SERVICE & MAINTENANCE
WARNING
BEFORE INSPECTING OR SERVICING ANY PART OF THIS MACHINE, SHUT OFF POWER SOURCE, DISENGAGE THE
HYDRAULICS, OPEN SHIELD AND MAKE SURE ALL MOVING PARTS HAVE COME TO A COMPLETE STOP.
The chipper blades will eventually become dull, making
chipping difficult and adding extra strain on the machine.
CHECK THE SHARPNESS OF THE BLADES EVERY
5-15 HOURS OF OPERATION AND SHARPEN AS
NEEDED.
The controller will indicate a blade/anvil service reminder
every eight hours as a reminder to check the chipper
blades. To reset the service reminder, see Section 4.7.3.
Your blades need to be sharpened if:
●
Machine vibrates severely when material is fed into
the chipper.
●
Chips discharge unevenly or have stringy tails,
especially when chipping green branches.
Before you sharpen the chipping blades, check for
permanent damage. Replace the blade if:
●
There are cracks, broken corners or nicks greater
than 1/8" (see below).
●
The base of the cutting edge is worn or has been
re-sharpened so that it no longer extends past the
chipping slot (see below).
5.2 ROTOR LOCK
Follow the steps below to install the rotor lock:
1. There is a hole in the shaft cap, the rotor shaft and
a matching hole in the bracket mounted to the rotor

bracket.
3. Install pin into the rotor shaft cap, bracket and shaft.
4. Remove pin when service and/or maintenance is
completed.
The rotor assembly has a lock mechanism. When
working on the rotor assembly, use the lock mechanism
