The chipping blades should clear the anvil by 1/16 inch to
1/8 inch. 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. Lift rotor access cover and expose rotor. Loosen the
two 1/2" bolts that hold the chipper anvil to the frame.
2. Measure the amount of clearance between chipping
blade and chipper anvil from inside of housing. The
gap should be 1/16" to 1/8".
3. Adjust inward or outward to desired measurement. Use
the nuts on the adjustment bolt (See Fig. 5.3).
4. Tighten bolts on chipping block to 75 ft. lbs. and resume
operation.
Remove the two bolts holding the anvil and use one of the
other three edges if the chipper anvil edge is damaged or
worn unevenly. Adjust for correct measurement.

Feeding too large or too much material at once may plug
the chipper. To clear a plugged disk, proceed as follows:
1. Allow all moving parts to come to a complete stop.
2. Remove the two 3/8” retaining bolts holding the access
cover to the chipper frame and lift up access cover.
3. Remove the lock pin from storage position (see
below).
4. Turn check valve clockwise to engage the jack pump.
5. Pump the handle to raise the feed roller until the lock pin
position aligns with one of the support bracket holes.
6. Secure the position by putting the lock pin through the
support bracket and lock pin position.
7. Clean the debris away from the chipper disk. Turn the
disk by hand to be sure it is free to rotate. Be careful
to avoid the chipper blades when cleaning out the
debris.
8. Remove the lock pin and put it back in storage
position. LEAVING THE LOCK PIN IN ANY OTHER
POSITION MAY INTERFERE WITH FEED ROLLER
OPERATION.
9. Turn the check valve counterclockwise to disengage
the pump and lower the jack.
10. Close access cover and replace bolts.
7. For blades that have been repeatedly sharpened,
ensure that the sharpened surface extends past the
chipping slot opening. If it does not extend past the
opening, the blades should be replaced.
