Caution :
Always wear safety glasses and hearing protection when grinding knives.
Gloves are also mandatory for performing the maintenance work.
Warning :
The blade has two cutting edges (reversible blade). Even though one side of the
blade can be blunt, the other side can still be razor sharp.
Caution :
Make sure that all chippings in the immediate vicini ty have been removed.
This minimises the risk of fire.
• Retain the existing cutting angle.
• Open the shredding chamber (see Chapter 11.2.4).
• Always grind the blade along the angled cutting edge (1).
• Never grind the rear side of a blade. In the case of
RESIST
TM
blades, the profile is on the rear side. If you
grind away the teeth, the blade will lose a great deal of
its cutting force.
• The grinding is performed by m oving the grinding disc
along the angled cutting-edge.
• Avoid excessive grinding in the same location (prevent
local discoloration of blades; this denotes heating that
causes the material structure to change locally and the
hardness to decrease).
• The top of the knife is subjected to the heaviest loads during shredding. Sharpen this as little as
possible so that it is not weakened.
Caution :
Minimise the duration of the grinding as much as possible in order to prevent
heating up. If a blade becomes discoloured, this denotes heating, and signifi cantly
decreases the operating li fe of the blade.
Correct and timely sharpening of the shredding knives will extend their
operating li fe. If the top of the blade is rounded-off, the shredding effi-
ciency will be reduced. In this event, further grinding of the blade serves
