Wear
All tools and tool components such as brushes, cutters, flail shafts and drum cores are subject
to wear and will be worn out after a given period of use. They must then be replaced. The ser-
vice 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.
The service life of the drum core can be increased greatly by frequent changing of the flail
shafts.The flail shafts must be replaced at the latest when the diameter of the grooves which
form in the flail shafts has diminished by 1 mm in relation to the original shaft diameter. The flail
shafts must be changed with each set of cutters.
The consequence of waiting too long before changing the flail shafts is the formation of „oval"
flail shaft holes in the drum core. Drum cores damaged in this way must also be replaced by
new ones.
Worn flail shafts may break in use and cause serious damage to the drum core and drive!
Changing parts subject to wear
Only use original Von Arx EOOD spare parts or the replacement parts indicated in the parts
lists.
Changing the dust apron
Check the dust aprons regularly and replace them in good time.
