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 axle.

-  Depending on the trailer type, the specific 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 specific working conditions or 

trailer configurations, 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 axle.

-  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 product

-  Decals or instructions fitted on the product 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 product. 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”. The 

“VALX Warranty Conditions” can also be downloaded from our website 

www.valx.eu.

-    Modification and / or conversion of the product without the written 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 the product 

periodically undergo severe tests. As a result, VALX is able to warranty the quality of these parts.

-  VALX can not assess for every single third-party product whether it can be used for the VALX product 

without any safety risk. This applies even if such products have already been tested by an accredited test 

authority. Therefore, the VALX warranty 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 roadworthiness of the trailer, all maintenance tasks must be 

carried out according to the prescribed VALX service intervals (see the maintenance chart in chapter 3), and 

in accordance with the operation and service instructions of the trailer builder.

-  Maintenance and repair is strictly reserved to trained and qualified service technicians.

 

1.5.1 

Before starting work

-  Make sure that the trailer is properly secured against rolling. See chapter 6.

-  Make sure that unauthorised persons have no access to the working area.

-  Make sure that the working area is sufficiently lit and ventilated.

-  Dress properly. Do not wear torn or loose fitting clothes, but wear protective clothing. Remove jewelery, 

watches, etc. to prevent them from being caught in moving parts.

-  Wear protective shoes and keep long hair out of the way.

-  Use a dust mask when advised.
