DISCONNECT SPARK PLUG WIRE FROM SPARK PLUG AND MAKE SURE ALL MOVING PARTS HAVE COME TO A COMPLETE STOP.
WARNING
1. Remove the discharge door by removing the retaining
bolt securing the discharge door to the chipper body.
2. Remove the two 5/16 x 3/4" bolts and nuts securing
the discharge screen to the frame. Pull the bottom of
the discharge screen outward to rotate the screen off
the lip.
3. Clean any trash or debris out from the screen area.
4. Place the top lip of the discharge screen into the slot
under the top slope of the chipper body and rotate the
screen so that the bolt holes align with the holes in the
chipper body.
5. Reinstall the bolts and torque to 17 Ft-lbs.
6. Replace the discharge door.
1. Remove the discharge door, discharge screen, belt
guards and rotor shaft end cap.
2. Loosen the bushing bolts holding the drive pulley to
the shaft and remove the pulley.
3. Loosen the set screw in the lock collars. Using
a punch and hammer, tap the lock collars in the
opposite direction of normal rotation. Remove the
lock collars.
4. Loosen the set screw in the center of the rotor
assembly.
5. Remove the two 3/8 x 1/2" bolts running through the
rotor shaft.
6. Using a rubber mallet or other soft hammer, drive the
shaft towards the chipper chute side of the machine.
7. Once the shaft has been removed, the rotor assembly
can be removed through the discharge opening.
8. To ease reinstallation, smooth any divots or marks in the
shaft caused by the set screws. Clean the shaft as much
as possible before reinstalling into the machine.
5.10 CLEARING A PLUGGED ROTOR
5.11 REMOVING THE ROTOR
The rotor weighs in excess of 100 lbs. It is extremely
important to support the rotor to prevent it from falling
or shifting as the shaft is removed.

8 h 8 h
1. Every 8 hours, lubricate PTO cross journals. Make
sure grease purges through all four bearings.
2. Every 8 hours, lubricate PTO inner tubes. Telescoping
members must have lubrication to operate successfully.
Telescoping members without fittings should be pulled
apart and grease should be added manually with a
brush.
3. Every 8 hours, lubricate the PTO shield retaining
bearing. Molded nipples on the guard near each guard
bearing are intended as grease fittings and should be
lubricated every 8 hours of operation.
WARNING
To prevent personal injury or property damage:
Disconnect the PTO driveline from the source providing
power or disconnect the driveline from the chipper
and make sure that all moving parts have come to a
complete stop, before servicing, adjusting or repairing.
