Warnings & Instructions

General Application and Warning Instructions for Projection Screens - By the Meter 

Valid from January 1, 2014

1. Creases
Projection films are generally packed and shipped folded. After opening and stretching the projection films evenly on all sides, the creases usually disappear completely. As far as technically possible, projection films can also be shipped rolled – at an additional cost for packaging and transport. This increases the likelihood of crease-free or complete crease recovery. The recovery process depends on room temperature, tension during installation, and time. Any visible remaining creases do not constitute a reduction in the value of the projection film.

2. Proper use of projection films
Projection films are optimized for front or rear projection depending on the type, for use with the usual angles of light incidence in video, slide, or film projections. A smooth and flat surface is only achieved by evenly tensioning the projection films on all sides. When used under strip or side lighting, uniform tension on all sides is essential. Any visible remaining creases, seams, or waves caused by tension or installation do not reduce the value of the projection film.

3. Evaluation of color deviations and brightness differences
Projection films are manufactured in large-scale facilities of the PVC industry and are subject to strict quality controls. However, even this industry has tolerances. These are very small and often cannot be noticed under normal lighting conditions. Rarely, these deviations become visible under certain application conditions. Please note that color deviations, which only become visible when the viewing angle corresponding to half the luminance is exceeded, are technically inherent and do not reduce the value of the film.

4. Use in roller screens
All projection films can be made by Tüchler® in roller screens in Superflat versions. Please request a quotation. The installation of projection films by third parties in roller screens is done at their own risk. Tüchler® is free of any liability and/or claims for damages in this regard.

5. Dimensional stability + tolerances for cut material
Projection films are made of a thermoplastic material. The material changes its stretch behavior, softness, and length with changes in room temperature. Therefore, cuts are always subject to a tolerance of +- 5% at a room temperature of 22°C.

6. Use in winter and cold regions
Please note that projection films can cool down significantly during transport. In such cases, projection films must be stored and warmed before opening in such a way that the core temperature inside the film package reaches >= 21°C. If the film is opened at a core temperature lower than 21°C, it will be stiff and may suffer cuts or irreversible impressions and white marks from moderately sharp edges. A too low core temperature before unfolding also causes persistent creases.

7. Lifespan of projection films
With proper use and storage at room temperature, your projection film can last for many years. Projection films contain plasticizers that gradually evaporate over time. After several years, this may cause effects such as color changes, yellowing, brittleness, or oily spots on the surface. These effects are not warranty-relevant defects but are normal material-related signs of aging.

8. Exclusion of DIN and other projection standards
The projection film has been optimized for use in theaters, operas, events, exhibitions, tours, and similar applications, and is characterized by its specific color, projection behavior, robustness, and fire resistance. The film was not developed for use in cinemas or similar environments. Any assessment according to applicable standards for projection surfaces, particularly DIN standards, and complaints based on them are excluded unless contractually agreed in writing on a case-by-case basis.


General Application and Warning Instructions for Projection Screens - Welded

Valid from 1 January 2014

1. Welds
Projection surfaces in which both edge lengths are produced larger than the web width of the selected projection films are welded from individual webs of the projection films. This welding is carried out using high-frequency technology. The resulting seams are very fine and invisible or non-disturbing for most applications as described in point 3. The noticeableness of the welds depends essentially on the film type, projection type or direction and does not represent a reduction in value.

2. Creases due to folding in storage:
Generally, projection foils are - if not offered separately - packaged folded up and sent off. In general, these creases disappear after opening and stretching the projection foils on all sides. If it is at all technically possible, projection foils can be sent rolled up too – for an additional fee for packaging and transport. This increases the likelihood of the foils being crease-free, or that the creases will disappear during the recovery process. The recovery process depends on room temperature, assembly stress and time. In the case of remaining visible creases, this does not constitute a reduction in projection foil quality.

3. Intended use for projection foils:
Depending on the type of product used, projection foils are optimised for use in incident or backlight projection for customary light incidence angles for video, slide or film projection. A smooth flat surface can only be achieved by stretching the projection foil on all sides with equal tension. The development of ripples and warping does not constitute a reduction in projection foil quality if the projection foil is not tensioned evenly on one or more sides. Use with strip or side lighting: even tension on all sides is mandatory. Visible remaining creases, seams and warping due to tension or assembly do not constitute a reduction in projection foil quality.

4. Evaluating colour deviations and variations in brightness:
Projection foils are manufactured in large-scale PVC industry plants and are subject to strict quality controls. However, there are variations within this industry too. These are very slight and are not noticeable in normal light conditions. These deviations are only visible in certain application conditions. Please note that colour deviations only become visible when the viewing angle corresponding to half-light density is surpassed; this is dependent on technical factors and does not constitute a reduction in quality.

5. Usage for rolling projection screens:
Tüchler® can provide all projection foils as rolling projection screens with a Superflat (tab-tension) finish. Mounting of projection foils on rolling projection screens by third parties is at your own risk. Particularly if non-tensionable (standard welded) screens are used with (electric-)rollers, waves, pleats or even damages are to be expected. Tüchler® remains free from all liability and/or damage compensation claims.

6. Dimension stability and tolerances:
Projection foils are made of thermoplastic material. Therefore, the material’s stretching properties, softness, and measurements vary according to changes in room temperature. Thus, cut products are subject to a tolerance of +- 2% at 22°C room temperature.

7. Use in winter and cold regions:
It must be noted that projection foils can cool off significantly during transport. In such cases, before opening the foils, ensure that the core temperature inside the packaging is at least 21°C. If the foil is opened with a core temperature below 21°C, it will stiffen and may tear or suffer irreversible impressions and stress whitening from moderately sharp edges. Low core temperatures before unfolding also result in persistent creases that do not disappear.

8. Projection foil shelf life:
With correct usage and storage at room temperature, you will be able to use your projection foil for many years. Projection foils contain softening agents that are exuded over time. Therefore, after a few years, colour change, yellowing, brittleness, oily patches on the surface can occur, and it may tear more easily. These appearances are not defects covered by warranty; these are customary, material-related effects due to aging.

9. Exclusion of DIN and other photography or cinematography standards:
The projection foil has been optimised for use in theatres, opera, events, trade fairs, tours, and similar, and therefore different types are distinguished by colour, projection behaviour, sturdiness, and flammability. The foil was not developed for use in cinemas or similar. Therefore, all evaluations based on norms for projection surfaces, in particular DIN, and claims based thereupon are excluded, unless this was expressly agreed upon in writing.

General application and warning instructions for flame-retardant cotton fabrics

Valid from 1 January 2014

Unless expressly noted otherwise, cotton fabrics marked flame retardant (hardly flammable) are treated with a semi-permanent flame retardant. This means that as long as the material is not soaked or washed, the flame retardant characteristics will persist. Therefore, soaking or washing will cause the loss of fire retardant characteristics. Flame retardant characteristics can be maintained through professional dry cleaning without stain removing agents and a low proportion of water. It is mandatory to carry out tests after dry cleaning.


General application and warning instructions for materials made of Trevira CS and polyester FR fibers

valid from November 2019

1. Washing properties of flame retardant materials
Trevira CS and Polyester FR fibre-based material can be washed according to the care label, without loss of fire retardant characteristics.

2. Loss of flame retardant characteristics due to care products
The use of fibre-affine care products such as fabric conditioners (e.g. Silan) can cause the loss of the material’s flame retardant characteristics!

3. Loss of flame retardant characteristics due to contamination
Soiling or applying foreign substances (e.g. painting/printing) to the fabric can cause the loss of the material’s flame retardant characteristics!

4. Regular inspection of flame retardant characteristics
Therefore, please make sure you ask an expert to regularly check the cloth’s flame retardant characteristics.


General application and warning instructions for velvets

valid from 1 January 2014

1. Packaging and acceptance of stage velvets sold by the metre:

All stage velvets sold by the metre are carefully packed, hanging in transport boxes. In general, the transport boxes are shipped lashed down horizontally on pallets.

WARNING: Upon acceptance, the purchaser must check that the transport boxes are delivered lashed down horizontally on pallets. If this is not the case, he must note this on the shipping documents. If the transport boxes arrive loosely (without being lashed down), it is probable that the boxes were transported or stored vertically. This leads to irreversible damage to the stage velvets. Noticeable signs are zebra /harmonica-shaped creases and pressure points which repeat in an arch shape along one or both edges. The shipper/transport company is responsible for such unambiguous transport damages.

However, the purchaser can only claim for this if he immediately notes the loose delivery of the boxes in the shipping documents upon delivery or completely refuses acceptance. Even if there is no visible damage on the outside of the boxes, it is possible that damage has occurred to the product! For all further matters, item 10 of the Tüchler Bühnen- & Textiltechnik GmbH General Terms and Conditions applies unmodified.

2. Colour accuracy and reflective stripes

2.1 Despite due care in the dyeing process, it is not possible to completely avoid minor colour deviations due to technical grounds. This also applies to within one and the same colour portion. Slight colour deviations, especially those which are not or hardly noticeable in velvets used to make curtains with folds, do not constitute a reduction in the quality of the stage velvet.

2.2 The angle of the pile can vary within a roll of velvet. This is due to technical grounds when winding the velvet, and causes a variation in reflection of the incident light. This can create the false impression that the colour is fading (=slow or continuous change of colour within a roll). This does not constitute a reduction in quality.

2.3 From the moment stage velvets are packaged, they are subject to a relaxation process caused by the material’s characteristics. This leads to micro-movements. As stage velvet can only move in one direction, in reaction to the pile on the roll, the rolls lose their circular shape. These non-circular rolls often show a clearly noticeable edge, which creates the impression that the stage velvet was not wound properly. The pile angle on this edge often contrasts significantly with the rest of the velvet roll which has remained round. This regularly causes very noticeable, but reversible reflective stripes. These reflective stripes do not constitute a reduction in quality.

2.4 Dependent on room conditions, the pile will realign itself after some time. The consistency and luxuriance of the velvet is only fully re-established after this takes place. This process can often take weeks. If reflective stripes or colour fading due to reflection persist despite a long recovery period, lightly steaming and softly brushing in the direction of the pile can shorten or support the pile recovery process. Please note: This process can take even longer in centrally heated, hot rooms lacking humidity.

3. Using velvet in assembly

3.1 The pile for velvet curtains is longitudinal. Therefore, it can either be assembled pile “up” or pile “down”. If the customer does not expressly ask for a specific pile direction, Tüchler finishes curtains pile up. This means that the colour appears richer and deeper when observed from a horizontal angle. In all cases, this means that pressure points or reflective stripes are less visible.

3.2 If the customer asks for pile down velvet or assembles the velvet in such a way, the customer is responsible for the risk that reflective stripes and pressure points are more visible.

3.3 After hanging, finished velvet curtains require time to recover. Dependent on the room climate, the pile only realigns itself after some time. The consistency and luxuriance of the velvet is only fully re-established after this takes place. This process can often take weeks. If reflective stripes or colour fading due to reflection continue to be present despite a long recovery period, lightly steaming and softly brushing in the direction of the pile can shorten or support the pile recovery process. Please note: This process can take even longer in hot rooms lacking humidity. The appearance and hue of the velvet can vary according to the height of the curtain and the observer’s angle of vision due to varying reflection of light.

4. Light fastness

Tüchler velvets are coloured under high standards. This also relates to light fastness. However, please note that no textile is absolutely lightfast. Sunlight damages all dyes and fibres. Therefore, curtains made of stage velvet should be lined, especially if they are exposed to direct sunlight. If the customer does not order lined curtains or lines the curtains themselves, then Tüchler remains free from all liability and/or damage compensation claims.

5. Light transmission

Generally speaking, velvet is not a perfect black out material. In daylight, or artificial backlighting, light can shine through so-called pinpricks and other smaller irregularities in the weave. These irregularities are due to construction and do not constitute a reduction in quality of the stage velvet.


General application and warning instructions for VIS 2000 velvet enhancement spray

valid from 1st November 2019

1. Application

Your cotton velvet must not be saturated with VIS 2000 to the point of dripping or running. If this happens, the flame-retardant effect may be compromised.

The treatment should only be performed while the velvet is hanging. Allow the velvet to dry thoroughly while hanging. Folding or creasing the velvet while it is damp or insufficiently dry can cause severe creasing that may not be removable.

2. Suitable materials

Use VIS 2000 exclusively on cotton velvets!
VIS 2000 is not suitable for polyester velvets, Trevira CS, or other types of fibers.

3. Application on cotton velvet from other manufacturers

When applying to flame-retardant cotton velvets from manufacturers other than TÜCHLER, test on a sample to ensure that the flame-retardant properties remain unchanged.

4. Color change

VIS 2000 does not alter the color of your cotton velvets but typically leads to a deepening and richer tone. Test on a separate sample before application! Never treat parts or sections of a curtain, always treat the entire surface.

5. Expiry date and storage

Observe the expiry date for storage. After expiration, the effect may be reduced, and spots may form after treatment, which are difficult to remove. If VIS 2000 develops an unpleasant odor, the storage time has been exceeded.

6. Handling sediment

If sediment forms before the expiry date, shake it well.

7. Use of sprayers

Use only sprayers that ensure fine and even atomization. Large droplets can cause staining.

8. Safety Data Sheet

Refer to the Safety Data Sheet.


General application and warning instructions on the topic of "sprinkler suitability"

Effective from 1 September 2024

1. Assessment of sprinkler suitability
The assessment of "sprinkler suitability" is carried out by Tüchler based on tests conducted according to the VdS guideline, showing that neither significant changes in water distribution nor delays in water penetration are caused.

2. Guidelines for using the material under fire suppression systems (sprinklers)

2.1 There are no known EN, DIN, ÖN, or other standards that have internationally recognized validity regarding the assessment of sprinkler suitability of materials.

2.2 In Germany, there may be requirements from insurance institutions (VDS). However, these are not required for every venue or trade show and have no legal basis outside Germany.

2.3 Check local regulations before using the material!

2.4 Have the material approved by local authorities before use!

2.5 Complaints or claims for damages arising from the "non-approval" of materials marked by Tüchler as "sprinkler suitable" in any form are excluded.

General application and warning instructions for the use, storage, and installation of dance and floor coverings

valid from September 1, 2024

1. Purpose and Quality Assessment
TÜCHLER dance and floor coverings are designed for use in the event industry, on stages, in theatres, operas, events, and similar applications. Please observe the indicated ratings and usage instructions! Quality assessments are therefore only possible in relation to the product-specific stated function. TÜCHLER dance and floor coverings are not designed for home or project use. Any assessment according to standards applicable to flooring or carpets, particularly DIN standards, and complaints based on them, are excluded unless otherwise agreed in writing in a contract.

2. Important Notice on Shoe and Sneaker Abrasion Marks
Since around 2023, shoes, particularly sports shoes (sneakers) with sole material, have appeared on the market that can leave significant abrasion marks on dance floors. These marks are caused by the rubbing of the sole material, which creates an extremely strong bond with the floor surface and is difficult to remove, even with the use of strong solvents and cleaning machinery. Light soles on dark floors and vice versa are particularly affected. Please note that such abrasion marks do not indicate a defect in the floor, but are caused by inappropriate footwear. Therefore, test the compatibility of shoes, especially sports shoes (sneakers) with elastic soles, with the dance floor before use.

3. Risk of Slippery or Slick Spots
Slippery spots on dance floors pose a risk of accidents. These are primarily caused by:

3.1. the interaction of skin oils and sweat, as well as polishing through dancing

3.2. the use of gloss cleaners and waxes

3.3. polishing during floor cleaning

Check your floors for slippery or slick spots before use and eliminate them with proper cleaning. If the required friction values of the dance floor are no longer achieved after several years of use, then the floor has reached the end of its technical lifecycle and must be replaced.

4. Cleaning
Therefore, clean your floor regularly and only with appropriate products, such as TÜCHLER cleaners, ANTISTAT, and BISON.
Never use gloss or polishing agents!

5. Storage of Dance and Floor Coverings
Recommended storage methods:

5.1. Store your floor covering rolled up, standing upright, or rolled on pipes, ideally on TÜCHLER dance floor transport trolleys.

5.2. When storing rolls horizontally in a stack, use load-distributing layers such as Styrofoam strips.

5.3. Never stack more than 4 layers (i.e., a maximum of 3 layers on the bottom one; for ConfiDance and Consor 20m rolls, 3 layers, i.e., a maximum of 2 layers on the bottom one) on top of each other, as the cores may deform and cause deep pressure marks.

5.4. If you receive floor coverings packaged in boxes, never stack more than 3 boxes on top of each other, i.e., a maximum of 2 boxes on the bottom one.

Dance floors may show pressure lines running across the length when stored correctly in horizontal layers, which do not affect their usability for dancing and therefore do not reduce their value.

6. Temperature Conditions
Dance and stage floors are made of thermoplastic PVC. Before rolling out, ensure the core temperature of the rolls is not below 21°C. Using the floor at a lower core temperature can cause stiffness and waves. There is a risk of breakage at arctic temperatures. Direct sunlight can cause permanent damage and significantly increased friction values.

7. Installation Methods

7.1. Portable (mobile) installation
The portable installation method is typical for stages, theatres, operas, but also for temporary event, performance, and rehearsal spaces, where this temporary use can often last for years. The floor strips are loosely rolled out, edge to edge, and taped together on the surface with tape. Please note that this installation method does not comply with general flooring installation standards. Complaints based on relevant flooring standards are therefore excluded. Note that the tape wears out and must be replaced regularly, the floor may shift, water may seep under the floor during wet cleaning if the tape is damaged, and waves may form. Using floor cleaning machines can lead to accidents and damage to the floor.

7.2. Semipermanent installation
The semipermanent installation method is typical for temporary event, performance, and rehearsal spaces where no tape is visible on the surface. This temporary use can also often last for years. The floor strips are loosely rolled out, edge to edge, and taped underneath with double-sided tape. Please note that this installation method does not comply with general flooring installation standards. Complaints based on relevant flooring standards are therefore excluded. Note that the tape may leave marks on the subfloor, the floor covering may form waves that need to be fixed by lifting and retaping, and water may seep under the floor during cleaning. Using floor cleaning machines can lead to accidents and damage to the floor.

7.3. Permanent installation
The permanent installation method must be carried out by professionals in accordance with general flooring installation standards. Please check if your floor covering is suitable for this installation method as noted above.

8. Subfloor Requirements
The subfloor must be dry, perfectly smooth, and free of cracks, non-adhering materials, loose layers, anti-adhesive chemicals, and dust. For concrete subfloors, the moisture content must not exceed 2.5%, and for screed, it must not exceed 0.5%. Check the relevant floor data before installation. A primer may be required for pre-treatment.

9. Gluing
Roll out the dance floor on site and allow it to acclimate for 24 hours at a minimum of 21°C. After the floor has relaxed, trim it with +5cm excess length on each side. Fold back the floor strips halfway and apply adhesive to the subfloor with a notched trowel. Press the strips into the adhesive bed from the center, free of air bubbles, and press firmly. We recommend Thomsit K 188E adhesive from Henkel. Please also observe the adhesive manufacturer's instructions! Note that dance floors are thin and unpatterned, so even the slightest irregularities on the surface will be visible, especially under raking, counter, or side lighting. This does not affect usability for dancing and does not reduce the value.

10. Welding

10.1. Hot air welding
After the adhesive has dried (please observe the drying times of your adhesive), open the seams with a suitable milling machine and clean them of any adhesive residues. We recommend using only TÜCHLER® welding rods designed for the Consor dance floor. Set the hot air to a minimum of 300°C. Before final welding, test and adjust your machine settings for temperature and speed. After the weld seam has cooled, remove the excess welding rod in two steps. First, remove about half of the rod with a suitable knife or planer. Only after the weld has completely cooled, shave off the remaining rod flush with the floor surface. Note that the colors of the welding rods may not exactly match the colors of the floors.

10.2. Cold welding
All suitable commercially available chemicals can be used. Preliminary tests must be conducted, and the cold welding agents must be used according to the manufacturer's instructions.


General application and warning instructions for Pallas protective covering

•Protective carpet tile Pallas was specially developed to be quick and easy to lay and take up and is ideal for both temporary and permanent installations.

•The carpet tile Pallas is a protective flooring for hall floors. It protects the hall floor from dirt and moisture (e.g. cigarette ash or spilled drinks during an event in the hall), and absorbs liquids. The carpet tiles will be subject to irreversible wear and tear but will thus prolong the life of your hall floor. Please observe the load capacity of your floor and do not place heavy objects (e.g. ladders or working platforms) directly and permanently on the carpet tiles. In order to prevent the carpet tiles from warping or lifting at the edges, avoid rolling across them with transport means.

•The color may vary between different production batches.

•The carpet tiles must be stored in the room where they are to be installed for at least 24 hours. If the Pallas carpet tiles are too cold when they are laid, they could be stiff and retain a so-called “residual tension”, which means that the self-laying property of the carpet tiles is limited and may even be subject to shrinkage afterwards.

•Please be sure the room temperature is approx. 18-25 °C with a relative humidity of approx. 50-70% when laying the carpet tiles. Strong temperature variations should be avoided. Suitable floors should be dry, clean, flat and free of cracks, dust, PVC, and wax.

•An arrow is printed on the latex bottom side of the carpet tile. The carpet tiles should be installed with all the arrows pointing in the same direction. If several pallets of carpet tiles are to be laid, they should be laid successively. Failure to do so may lead to the impression of apparent color differences when light falls on the carpet tiles.

•Our carpet tiles are characterized by very good self-laying properties and low slip behavior. To ensure the carpet tiles fit perfectly and do not move, the edge regions should be fixed in place with suitable fixing means such as gaffer tape. Double sided tape will damage the latex backing of the carpet tile!

•The carpet tiles should be vacuumed to clean them of any loose dirt before they are removed. Only powerful industrial vacuum cleaners with a brush attachment should be used.

•We recommend in any case that you clean the entire carpet surface to avoid any visual differences later. If possible, stains should be removed immediately with a fresh, clean, white, slightly damp cotton cloth. A mild cleaning spray can be used for stronger stains.

•The carpet tiles must be dry before they are stacked flatly on top of each other with the edges aligned! The carpet tiles should then be stored either on pallets with a flat solid surface or on storage carts available from Tüchler. Max. load capacity approx. 500 kg, (equivalent to approx. 90 carpet tiles or 180 m²). Please observe the maximum carrying capacity of your floor! There is a risk that the weight of the loaded cart may damage the floor!

•When storing the carpet tiles, they should not be stacked any higher than 1.1 m. The carpet tiles should be stacked carefully with carpet surface to carpet surface and latex surface to latex surface.

•Due to the wide variety of applications and locations where the carpet tiles can be used, we do not assume any responsibility for, cleaning, storage and working conditions that are beyond our control and can not guarantee the installation results.



Special warnings about flame retardants and their application

valid from September 1, 2024

1. Observe work instructions, safety data sheet, and warnings
Before processing, observe the work instructions, safety data sheet, and warnings. Always impregnate only fully dried and clean materials. In general, cover all materials exposed to spray mist. Metals, plugs, electrical and electronic devices, as well as wood, stone, and sensitive textiles and wallpapers, can be sensitive to moisture. Residues of fire protection chemicals can cause damage such as rust or discoloration and are excluded as grounds for complaint.

2. Carry out preliminary tests!
There are fabrics and floor coverings, especially made from synthetic fibers and blends, that cannot be made sufficiently flame retardant according to the current state of the art! Therefore, preliminary tests are absolutely necessary!

3. Health and Occupational Safety
For general occupational safety and health protection, please observe the following points: Keep out of reach of children; Keep away from food, drink, and animal feed; Do not eat, drink, or smoke while working; Do not inhale spray mist; Wear a respirator mask; Wear safety goggles; Avoid eye contact - rinse with plenty of water if necessary - consult a doctor if symptoms occur; If swallowed, seek medical advice; After finishing work, thoroughly clean hands, clothing, and equipment with water; Be aware of the risk of corrosion to iron and non-ferrous metals (cover); Rinse containers thoroughly with water before disposal; Follow the safety data sheet!

4. Skin compatibility

ECOGARD® STANDARD 100 contains an active ingredient certified as an ACP (Accepted Chemical Product) according to OEKO-TEX®, making it suitable for textiles in direct contact with the skin of babies and young children. This flame retardant was specially developed for high skin compatibility and can be safely used in areas where direct skin contact is unavoidable.

The flame retardant products ECOGARD® CELL and BIO PLUS are also generally very skin-friendly. However, allergic reactions cannot be completely ruled out in individual cases, so direct skin contact with the products or treated materials should be avoided where possible. Therefore, the use of these products for upholstered furniture with skin contact is not recommended.

ECOGARD® B45 V.2 has specific hazard warnings according to CLP Regulation (EC) No. 1272/2008 and is currently recommended exclusively for applications without skin contact.

5. Observe official regulations!
Observe local official regulations. The buyer is responsible for inquiring in good time with the relevant authority as to which standards and proofs must be met. In many cases, authorities require proof of proper impregnation by a specialist company, such as factory certificates. Tüchler or ECOGARD® distributors offer these services. Note that there are no general approvals for flame retardants. All certificates are intended solely to document the general suitability of a flame retardant for a specific material or material group. Neither flame retardant certificates nor factory certificates may be used as evidence or proof of compliance with a fire-retardant class for the impregnated material.

6. Lighter test
The lighter test may only be carried out for personal safety by trained personnel, over non-combustible surfaces, in well-ventilated rooms, and only on separated material samples of approximately 10 x 20 cm. Note that the lighter test does not provide any indication of passing a standard test!

7. Attention after wetting, washing, or dry cleaning
ECOGARD® flame retardants are water-soluble. Wetting or washing dissolves ECOGARD®, and re-treatment is mandatory. After dry cleaning, the flame retardant effect must be checked.

8. Limitations of flame retardant impregnation
Flame retardants protect against small fires caused by accidents and carelessness. In the event of a major fire, arson, or the use of accelerants such as gasoline, flame-retardant materials fail and must be included in the fire load.

9. Side effects and disclaimer of liability
ECOGARD® products are designed for commonly used materials. Depending on the material, unwanted side effects may occur, such as: Impairment of colorfastness, such as lightfastness, rub fastness, etc., color shifts, reduced tear strength, corrosion, changes in texture, dimensional changes, altered soiling behavior, edge formation due to water droplets, allergic reactions such as skin irritation, dripping of the flame retardant from synthetic fibers, especially acrylic. Complaints and claims for damages based on the aforementioned or similar occurrences are excluded, regardless of the time between the occurrence of the unwanted event and the impregnation.

10. Flame retardant impregnation by TÜCHLER
Warranty claims by the buyer under the General Terms and Conditions can only be asserted if the items (materials) to be impregnated and other nearby items (materials) are approved in writing by TÜCHLER. Otherwise, the risk of color changes, dimensional changes, and any other changes, as well as compliance with the relevant standards of the impregnated items (materials) and any nearby items (materials), is borne by the buyer. The above points apply in full, especially points 5 and 9.

Note: Withdrawal from the purchase, exchange, or return of flame retardants is only possible for unopened original containers with undamaged seals. If the seal has been opened, broken, or otherwise altered, withdrawal and exchange are excluded even in the case of transactions subject to e-commerce or distance selling law.

General application and warning instructions for adhesive tapes

Valid from January 1, 2014

1. Adhesive tape ratings
Please note that the ratings are based on comparisons within our product range.

2. Adhesive residues
Please note that all adhesive tapes, even with the best rating, can leave adhesive residues depending on the surface, pressure, mechanical stress, and application duration.

3. Aging of adhesive tapes
Please note that adhesive tapes may age during storage (more than 1-2 years), depending on the temperature, which alters their properties, particularly adhesion and residue behavior.

4. Caution with stone floors and porous surfaces
Be especially cautious with stone floors and other porous surfaces such as terracotta or clinker, as these often absorb chemical components of adhesives, which can lead to dark streaks on the stone that fade only slowly or not at all.

5. Proper tape removal technique
Always remove adhesive tapes evenly. Jerky removal increases the likelihood of leaving adhesive residues and can damage the substrate due to material peeling. Pay particular attention to this on wooden floors, lacquered and coated surfaces, and other sensitive surfaces.

6. Testing before use
Always test before use:
6.1. on the respective surfaces,
6.2. according to the planned duration of adhesion,
6.3. under the planned mechanical stress,
6.4. under the planned mechanical pressure.

7. Complaints and disclaimer of liability
If adhesive residues and other results are due to the typical properties of an adhesive tape, complaints are excluded. Claims for damages are in any case excluded.

Connections should only be made by personnel trained in the respective field.

2.3 During commissioning/operation:

Before first commissioning and daily operation, a visual inspection and the prescribed checks must be carried out.

Electric chain hoists/winches should only be operated if the existing protection and safety devices are functional.

Any damage to the electric chain hoists/winches and any changes in operating behavior must be immediately reported to the responsible person.

After switching off or stopping the electric chain hoists/winches, they must be secured against unintended and unauthorized use.

Avoid any operation that compromises safety.

3. Documentation of usage time

As an operator, you are required to annually determine the usage time and resulting remaining service life for each chain hoist/winch and record this in the inspection book, or provide proof of standard use within the framework of service life determination. If the determination and documentation of the remaining service life are not carried out, the affected chain hoists/winches must be decommissioned after 10 years or undergo a complete overhaul, which could significantly exceed the costs of a new investment.

4. Recurring inspections

Each device/system operator must properly record all inspections, maintenance, and revision work in the inspection book and have them confirmed by the responsible/specialist person.

ATTENTION! Equipment and cranes must be periodically inspected by a specialist. Essentially, visual and functional inspections must be performed, assessing the condition of components for damage, wear, corrosion, or other changes. Furthermore, the completeness and effectiveness of safety devices must be evaluated. Dismantling may be required to assess wear parts.

ATTENTION! Load-bearing elements must be inspected along their entire length, including concealed parts.

ATTENTION! All periodic inspections must be initiated by the operator.

5. Warranty

The warranty will be voided if installation, operation, inspection, and maintenance are not carried out according to these operating instructions. Repairs and fault rectifications under warranty may only be performed by qualified personnel after consultation and authorization by the manufacturer/supplier. The warranty also expires if modifications are made to the product or if non-original spare parts are used.

6. National and regional regulations

Please observe the national and regional regulations relevant to the respective application, which may differ significantly even between EU member states.

In Austria, chain hoists/winches are generally subject to the Austrian Occupational Health and Safety Act §37, §38, Austrian Workplace Equipment Regulation §8, §16, ÖVE/ÖNORM E 8701, and ÖNORM-DIN-EN 17206.

In Germany, chain hoists/winches are generally subject to the UVV, DGUV Regulation 3/4, 17/18, EN 50678:2021-02 / EN 50699:2021-06 VDE 0701/0702, and ÖNORM-DIN-EN 17206.
