5 INCH CHIPPER/SHREDDER/BLOWER
SERVICE & MAINTENANCE
WARNING
BEFORE INSPECTING OR SERVICING ANY PART OF THIS MACHINE, SHUT OFF POWER SOURCE,
AND MAKE SURE ALL MOVING PARTS HAVE COME TO A COMPLETE STOP.
The chipping blades should clear the anvil by 1/16 to
1/8". Check the clearance every 8 hours of operation and
adjust if needed. The chipping anvil is reversible. All four
sides of the anvil can be used for chipping.
To adjust the anvil:
1. Loosen and remove the 3/8" carriage bolt securing
the knife access cover.
2. Open the knife access cover exposing the chipper
shredder compartment.
3. Remove the dust cover on the front side of the
machine.
4. Remove the belt guards on the rear of the machine.
(PTO models, remove the joint shield first).
5. Loosen the set screws holding the lock collars on the
front and rear 2-bolt flange bearings.
6. Use a punch and hammer to tap the lock collars
directly opposite normal rotation.
(On the front side,
tap punch in a CW rotation. On the rear side, tap
punch in a CCW rotation.)
7. Using a rubber mallet, tap the end of the rotor shaft
to obtain 1/16" to 1/8" clearance. Rotate the rotor and
check the clearance on all chipping blades.

8. Once clearance has been set, the lock collars must
be replaced and retightened. Using a punch and a
hammer, rotate the lock collars in the direction of
shaft rotation (i.e. counter-clockwise on the rear
bearing and clockwise on the front bearing) and set
them with a positive hammer tap. Tighten the lock
collar set screws.
9. Loosen the set screws holding the belt pulley on
the rotor shaft. Move the pulley on the shaft so it is
aligned with the engine drive pulley (towable models)
or PTO drive pulley (PTO models). The pulley should
be moved an equal but opposite amount that the rotor
was moved.
10. Insure the pulley drive key is completely seated under
the pulley and tighten the set screws.
11. Check pulley alignment by laying a straight-edge
across the pulley faces. Pulley faces should line up.
If not, determine which pulley to adjust and repeat
alignment check.
12.
Replace the (joint shield PTO models only) belt guard
and plastic bearing cap.
Feeding too large or too much material at once may plug
the chipper. To clear a plugged rotor, proceed as follows:
1. Move tractor throttle to slowest positions, disengage
PTO lever and allow machine to come to a complete
stop. Shut off tractor.
2. Loosen and remove the 3/8" carriage bolt securing
the chipper access cover.
3. Open the knife access cover, exposing the chipper
shredder compartment.
4. Clean the debris out of the shredding rotor and/or
chipper top discharge area and tube. Turn the rotor
by hand to be sure it is free to rotate.
5. Restart tractor and resume operation.
If the machine becomes plugged, shut off the engine,
disconnect the spark plug wire and allow the machine
to come to a complete stop before clearing debris.
Do not operate machine without proper guards and
screens in place.
