Maintenance instructions
The following installation, operating and maintenance instructions relate to BPW rubber
suspension axles, torsion bar axles, towing equipment and chassis. They are a constituent
part of the warranty conditions. Adhere to the relevant operating instructions of the vehicle
manufacturer or of the other vehicle component manufacturers.
Completion of the maintenance work in accordance with the prescribed intervals is essen
tial in order to maintain the operating safety and roadworthiness of the vehicle.
The correction of any defects found or the replacement of any worn parts should be
carried out by a BPW aftersales service workshop, unless the vehicle user has at his
disposal appropriately skilled incompany workers and the necessary technical facilities.
When installing spare parts, it is strongly recommended that only original
BPW components are used. Parts approved by BPW for trailer axles and
suspensions regularly undergo special test procedures and as a result BPW
is able to guarantee their quality.
However, BPW cannot assess for every single thirdparty product whether it
can be used for BPW trailer axles and suspensions without any risk to safety.
This applies even if such products have already been tested by an accredited
test authority.
Our warranty becomes null and void if spare parts other than original BPW
parts are used.
