Maintenance work

Always interrupt the energy supply before performing maintenance work.
Wear
All tools and tool components are wear parts and will be worn out after a given period of use.
They must then be replaced. The service life of the individual components varies.Apart from
wear caused by operating use, it also depends on the type and characteristics of the material of
the surface to be treated and on the requisite power during use.
Changing wear parts
All Von Arx wear parts and replacement parts are made on the latest machines. This guarantees
a perfect fit for all parts.
Do not use spare parts of unknown manufacture! Even if they look the same, there may be
considerable differences in manufacture and/or materials which may be prejudicial to active
and passive safety.
All warranty claims lapse if spare parts other than those made by Von Arx or recommended
makes are used.
