9.7 Rotor Knife Maintenance
WARNING!
Never operate a machine with any guards
or shields removed. The machine is shown
here with guards and/or shields removed for
illustrative purposes only.
W001
CAUTION!
Wear heavy gloves, turn the rotor slowly, and be
aware of your hand positions. The rotor knives
are sharp and can cause cuts. Finger and hands
can become pinched or wedged between the
rotor and the rotor housing.
W032
IMPORTANT! If replacing or sharpening a knife, do the
opposite one on the rotor as well to maintain the rotor
balance. The clearance must be the same for each knife
when it passes the ledger knife.
IMPORTANT! Rotor knives can be sharpened on both sides,
as long as the correct clearance between the rotor knife and
the ledger knife is maintained.
IMPORTANT! When sharpening a rotor knife, make sure
that an equal amount of material is removed from each knife
to maintain the correct rotor balance.
Observe the rotor knife performance during operation.
The rotor knives need to be sharp for the best performance.
Keep the leading edges of the knives sharp to reduce the amount
of power required during operation. If the chipper is not pulling
the material or the material must be pushed into the chipper, the
rotor knife edges may be rounded over (are likely dull).
Check the rotor knife sharpness daily or every eight hours.
Check the rotor knife sharpness more often if you are
processing material with a lot of sand, soil, or dirt in it. If a rotor
knife become dull, rotate both knives. Set the opposite edge
of each knife to the leading edge. If the knives were previously
rotated, and both edges are dull, replace both knives or sharpen
all four knife edges.
Sharpen the rotor knives after every 50 hours of operation.
Always rotate, replace, or sharpen both knives at the same time.
