7�2�5 ROTOR BLADES:
The rotor and ledger blades need to be sharp for the Chipper to perform as expected. Periodic inspection
is recommended. Keep the blades sharp to reduce the amount of power required during operation.
Watch the sharpness of the blades when processing material with a lot of sand, soil or dirt mixed with
it. Reverse or sharpen the blades if the cutting edge becomes dull.
The rotor is equipped with 4 blades spaced evenly to keep the rotor in balance. If one needs to be
changed, the one opposite should also be changed.
It is recommended that the rotor blades be removed from the rotor when sharpening. Always sharpen
the blades at a 45° angle to provide the best cutting effect as it meets the stationary blade. Be sure to
tighten the blade mounting bolts to their specified torque when re-installing the blades to the rotor.
1.
Ensure the machine is set in
Safe Condition
(See Section 7.2).
2.
Remove the bolt that secures the
upper rotor housing, and carefully
open the rotor housing.
3.
With care, slowly rotate chipper rotor
plate until the rotor lock lines up with
lock hole in the rotor plate.
4.
Engage the rotor lock, and ensure
it snaps into the lock hole. Do not
allow the rotor lock to snap into the
chipper blade slot, damage to the
blade may result.
5.
Remove the bolts that hold the rotor blade
to the rotor, remove the blade.
6.
Rotate the blade and reinstall or replace
with new or re-sharpened blade.
7.
Ensure the blade is properly oriented, with
the leading edge out. The blade is designed
to fit into the rotor one way only. See
diagram for proper installation.
8.
Tighten bolts as specified in the torque
chart.
9.
Repeat steps for remaining blades.

Caution: Avoid Serious Injury
The rotor is very heavy, turn
rotor slowly and be aware of
hand positioning: avoid getting pinched or
wedged between the lower rotor housing
and rotor.
