Attention!
When working with upturned blades, in particular, please ensure that no coarse
fragments reaches the mechanical parts under the hand guard of the device. Moveable
parts of the device could be blocked as a result and even be destroyed.
The device must be checked for dirt and impurities in the mechanical part after each
of such applications, and cleaned if necessary.
Unscrew handle and pull back the hand guard according to illustration 1.
Clean dirt and shards from mechanical parts as shown in Illustration 2 and blow
out with compressed air carefully.
If the hand guard tabs to the blades are considerably worn or torn, the entire hand
guard must be replaced.
12.2.2 Main checks
The mechanical transfer elements on the device are subject to very high
mechanical stresses and therefore they must be checked after 500 operating
hours at latest. Thereby, appearances of attrition can be detected early so that
breakages can be avoided by timely replacement of these worn parts.
Perfect parts can be reassembled after careful lubrication with LUKAS special
grease.
Parts with limited wear (fretting marks) can be refurbished by polishing and reassembled
after careful lubrication with the corresponding grease.
If there are heavier traces of wear, the damaged parts must be replaced (in pairs).
At these intervals, it is essential to check the blades for crack. A special crack test
kit is available.
From time to time the cutter must be cleaned and lubricated with oil to protect it
against external corrosion.
