1 General safety instructions and regulations
1.1 General
- VALX accepts no liability for any damage or physical injury caused by non-compliance with the safety
instructions and regulations in this manual, or by carelessness during any maintenance or repair task on the
VALX trailer landing gears.
⁻ Depending on the trailer type, the specic repair or maintenance task(s) that have to be carried out, the
workshop conditions, the environmental circumstances and the cargo that may be loaded, additional safety
instructions may be applicable. As VALX has no direct control over these specic working conditions or
trailer congurations, it is the workshop’s sole responsibility to ensure that the national accident prevention
guidelines and the local Health and Safety regulations are adhered to. Please inform VALX immediately if
you have dealt with unsafe situations that have not been described.
1.2 This manual
- Read this manual thoroughly before performing any maintenance or repair task on the trailer landing gears.
- Keep this manual for future reference. Retain the manual in a safe place in the workshop.
- Carry out the procedures in the order given. Do not change the order of the steps.
1.3 Decals and instructions on the trailer landing legs
- Decals or instructions ed on the trailer landing legs are part of the safety features provided. They must not
be covered or removed, but must be present and legible throughout the entire life of the trailer landing leg.
Damaged or illegible decals and instructions must be replaced or repaired immediately.
1.4 Warranty and original VALX parts
- All products of VALX are covered by warranty as stipulated in the “VALX Warranty Conditions” supplied
with the product. The “VALX Warranty Conditions” can also be downloaded from our website www.valx.
eu.
- Modication and / or conversion of the product without the wrien consent of VALX is not allowed at the
risk of forfeiting all warranty rights.
- When replacing parts, ONLY use original VALX spare parts. Parts approved by VALX for use in trailer
landing gears periodically undergo severe tests. As a result, VALX is able to guarantee the quality of these
parts.
- VALX can not assess for every single third-party product whether it can be used for VALX trailer landing
gears without any safety risk. This applies even if such products have already been tested by an accredited
test authority. Therefore, the guarantee becomes null and void if spare parts other than original VALX parts
are used.
1.5 Maintenance and repair
- In order to maintain the safe operation and the road worthiness of the trailer, all maintenance tasks must be
carried out according to the prescribed VALX service intervals (see the maintenance chart in chapter 6), and
in accordance with the operation and service instructions of the trailer builder.
- Maintenance and repair is strictly reserved to trained and qualied service technicians.
1.5.1 Before starting work
- Make sure that the trailer is properly secured against rolling.
- Support the trailer close to the landing legs so it can’t fall down.
- Make sure that unauthorized persons have no access to the working area.
- Make sure that the working area is suciently lit and ventilated.
- Dress properly. Do not wear torn or loose ing clothes, but wear protective clothing. Remove jewelry,
watches, etc. to prevent them from being caught in moving parts.
- Wear protective shoes and keep long hair out of the way.

M_2080-01_EN 9
1.5.2 During work
- Stay alert and watch what you are doing. Use common sense. Do not work on the trailer landing gears when
you are tired or have been taking alcohol, medicine or drugs. Do not smoke.
- Use a hoist when lifting 25 kg or more. Only use suitable and technically perfect lifting devices with
adequate lifting capacity built in compliance with all safety measures. Fastening of loads and instructions to
the operator of the lifting device are restricted to experienced personnel who are within sight or sound of the
operator of the lifting device.
- Only use tools, parts, materials, lubricants and service techniques that were approved by VALX. Do not use
contaminated or used lubricants. Used lubricants, cleansing agents and expended landing gears parts must
be disposed of in an environmentally safe way.
- Avoid bodily contact with lubricants.
- Never use worn tools and do not leave tools behind on the trailer landing gears or on the trailer.
- Never weld on any part of the trailer landing gears or suspension without the prior wrien permission of
VALX.
- Never re-use self-locking xing materials. Always replace them.
1.5.3 When work is nished
- Inspect the landing legs. Check for damage, leakage or defects. Any part removed for maintenance or repair
purposes must be reed and checked immediately upon completion of the work.
- Do not clear a trailer landing leg for operation unless it was established that it is absolutely safe and in
perfect working order.
1.6 A contribution to the protection of our environment
Please obtain information about recycling or environmentally friendly processing of parts and materials that
have been replaced during maintenance or repair tasks.
Almost all used lubricants are considered to be chemical waste. For the disposal of these a specialized company
must be contacted.
