Troubleshooting & Repair
TROUBLESHOOTING
While normal care and routine maintenance will extend
the life of your chipper/shredder, prolonged or constant
use may eventually require that service be performed to
allow it to continue operating properly. The troubleshoot-
ing guide below lists the most common problems, causes
and remedies.
See the service information on the following pages for
instructions on how to do most of these minor repairs
yourself. If you prefer, all of these procedures can be
performed for you by your local authorized dealer.
SYMPTOM
Engine won't start.
Engine runs, but rotor.
won't turn.
Engine runs, rotor turns, but no
material is being discharged.
Excessive branch vibration when
chipping materials.
Unusual noise or vibration when
processing material.
Vacuum not working.
Never attempt to perform any of these proce-
dures with the engine running. Always turn the
engine off, let the rotor come to a complete stop,
and disconnect the spark plug wire from the
