TROUBLESHOOTING & REPAIR
7. Install the new chipper knives using the two socket
head cap screws, and two new lockwashers, torque
to 18-20 ft. lbs. Never reinstall chipper knives with
used lockwashers, as used lockwashers may not
hold the knives adequately.
8. See Figure 18. Reinstall the access plug removed
earlier for capscrew access.
9. Reattach the shredder hopper and chipper cone
using the hardware removed during disassembly.
Replace any hardware that appears to be damaged
or worn excessively.
10. Check all hardware for tightness and correct
assembly before attempting to start your unit. Do not
attempt to start the unit if extra hardware is left over
after reassembly is complete. Check for proper
chipper knife assembly before proceeding.
11.Test the unit before attempting to use it to perform
chipping. Start the unit, and check for unusual noise
or vibration.
Shut the unit off immediately if either situation
occurs and reinspect chipping knives to confirm
correct positioning and assembly.
If assembly is correct, the blades may not have
been sharpened evenly--causing an imbalance.
Remove the blades and sharpen the evenly.
Recheck the unit. If problem persists, contact your
local dealer for assistance.
Deflector Shield
The deflector shield must pivot freely at all times, or
processed material could back up, clogging the unit and
requiring disassembly to clear.

Figure 19. Removing Chipper Knife Through Front
Opening
Never use the unit unless the deflector shield is in
place and operating properly. Material could be
ejected out of the discharge chute with great force,
injuring you or bystanders.
WARNING
Never use a malfunctioning unit to process
material, even if it appears to be chipping material
adequately. An unexpected kick back could occur,
causing serious injury to you or bystanders.
Serious equipment damage could also result,
voiding the warranty and requiring extensive
repairs by a qualified service location.
