number of possibilities for sharpening is unnecessarily reduced. For the
sharpening process, use soft grinding wheels (Quality 40 H or 46 K). Cutters,
which have grinding cracks, are not to be reused due to danger of breakage
during operation.
3. Whet the cutting edges of the cutting cutters using a whetstone.
NOTE: the service life of the cutting cutters can be increased by taking these
measures.
4. Set the cutters and bed knives (refer to “Setting the cutters”).
5. Mount the cutters and bed knives (see “Mounting the cutters and bed knives”).
NOTE: The cutting cutters, in particular the cutters, should only be sharpened or
replaced in sets. There is a danger of balance error if a combination of cutters from
different cutter sets is used.
Danger of cutting caused by sharp cutters at all times—even when rotor is at
standstill. Serious Injury especially to the hands and fingers can occur. Wear
protective gloves!
Setting the Cutting Knives
Cutters for the CMS series shredder do not have to be adjusted. All adjustments have to
be done with the bed cutters. To simplify cutter setting and shorten standstill periods
when replacing cutters, bed cutters have 4 adjusting screws, 2 each for pushing and
pulling the cutter. Having several cutter sets helps to avoid standstill periods. Correct
and careful setting of the gap between the cutters and bed knives (cutting gap) is
important for productive capacity of the shredder. Factors for the size of the cutter gap
are the size of the rotor, the design of the rotor, and the material to be ground.
