Service and Maintenance
61
Replace broken shear bolts with one the same size. Always
determine the cause of the problem and correct it before
resuming work. Shear bolts are available from your distributor
or dealer.
8.6 Twig Breaker
Inspect the twig breaker for damage, bent or missing teeth
every 50 hours.
The twig breaker is located inside the lower rotor housing.
Material in the chipper is broken up into smaller pieces as the
discharge paddles rotate past it.
A damaged or worn twig breaker should be replaced.

8.7 Rotor Blades
Check rotor blade sharpness daily.
If the chipper is not pulling the material or material has to
pushed into the chipper, the rotor blades are probably dull.
Reverse or sharpen the blades if the cutting edge becomes dull.
Check blade sharpness more often if processing material with a
lot of sand, soil or dirt in it.
Keeping the blades sharp reduces the amount of power required
during operation.
Sharpening Rotor Blades
1.
Remove the blades from the rotor to sharpen. Sharpen at a
45° angle to provide the best cutting effect.
IMPORTANT! Make sure equal amount of material is
removed from each blade when sharpening to maintain
proper rotor balance.
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.
