6.2- Chopper knives sharpening
This operation is more important on machine
maintenance, because aim at good performance and
durabilityoftheknives(1).
The sharpeness should be made in such a way to
preserve the characteristics of the knives and the
temperingofthesteel.
Sharpen the knives when you see that the quality of
theparticlesisdecreasing.
Procedure:
a) Loosen the latch (2) and open cover (3) from the
motorcompartment.
b) Lock the impeller (4) with a wood shim to avoid that it
turnduringboltremoval(5).
c)Removeboltsandnuts(5)andremovetheknives(1).
IMPORTANT:Sharpenalwaysalltheknifes!
d) Sharpen each knife with an appropriate emery,
avoiding overheting and variation on wire color. See
tablebelow.
IMPORTANT:
-Don’tcoolhotknifeswithwater.Itcancauselashing.
- Do not sharpen the knife chamfered surface, but the
