SERVICE & MAINTENANCE
BEFORE INSPECTING OR SERVICING ANY PART OF THIS MACHINE, SHUT OFF POWER SOURCE,
DISCONNECT SPARK PLUG WIRE FROM SPARK PLUG AND MAKE SURE ALL MOVING PARTS HAVE COME TO A COMPLETE STOP.
WARNING
ANVIL BLADE
GAP= 1/16"
-1/8"
The chipping blades should clear the chipper block,
located inside the frame on the bottom edge of the chipper
chute intake, by 1/16" to 1/8" (Figure 5.2). To adjust the
blade clearance, proceed as follows:
1. Remove the lower belt guard, discharge door,
discharge screen and the access cover.
2. Loosen the bushing bolts holding the pulley to the rotor
shaft on the front side.
3. Remove the rotor shaft cover on the rotor shaft rear
side.
4. Loosen the set screws on the lock collars.
5. Use a punch and hammer to tap the lock collars in the
opposite direction of normal rotation so they rotate and
can be removed.
6. Using a rubber mallet, tap the end of the rotor shaft to
obtain 1/16" to 1/8" clearance. The blade clearance can
be viewed through the discharge opening. Rotate the
rotor and check the clearance all chipping blades.
7. Once clearance has been set, the lock collars must
be replaced to retain the setting. Slip the lock collars
over the hub on the bearings. Using a punch and a
hammer, rotate the lock collars in the direction of shaft
rotation and set the lock collars with a hammer tap.
Tighten the lock collar set screws.
8. Loosen the bushing holding the belt pulley on the rotor
shaft. Move the pulley on the shaft so it is aligned
directly below the similar pulley on the engine shaft.
The pulley should be moved an equal but opposite
amount the rotor was moved.
9. Replace the rotor
shaft cover, discharge
door, discharge screen
and the lower belt
guard.

TO REMOVE:
1. Remove the discharge door by removing the pivot rod
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.
TO INSTALL:
1. Place the top lip of the replacement screen onto 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. Reinstall the bolts and
torque to 17 Ft-lbs.
2. Replace the discharge door.
