2. Tilt access cover open to allow access to rotor.
Rotate the rotor so that the bolts holding the blades
are best accessible.
3. Secure the rotor in place by installing the disk lock.
4. Remove the two bolts that hold the blade to the
disk. The hardware can be reused. Repeat for
remaining blade.
5. The blades have two edges and can be reversed
one time before sharpening.
6. Place a blade on the disk and attach using two
M16 x 2.0 bolts and washers. Torque bolts to 120
lbs-ft. Repeat for the remaining blade.
SHARPENING THE BLADES
The blades can be ground on a bench grinder or by a
professional.
1. Never sharpen or grind the mounting surfaces of
the blades. This will cause the edge to roll and the
blade will be damaged, resulting in poor chipping
performance.
2. Regrind the angled edge of the chipping blades to
45 degrees. (See Figure 5). Make sure some type
of fixture is used to correctly hold the blade at the
proper angle.
3. Be careful when grinding so that the blade does
not become overheated and change color. This will
remove the heat-treated properties.
Figure 5. Blade Sharpening
4. Use short grinding times and cool with water or
some type of liquid coolant.
5. Remove an equal amount off each blade to
maintain rotor balance.
6. Small imperfections such as nicks and burrs on the
flat side of the blade will not affect the chipping
performance of the machine.
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.

ADJUSTING THE CHIPPER ANVIL
The chipping blades should clear the anvil by 1/16 inch
to 1/8 inch. Check the clearance every 8 hours of oper-
ation and adjust if needed. The chipping anvil is revers-
ible. All four sides of the anvil can be used for chipping.
To adjust the anvil:
1. Remove the two 3/8" bolts on the rotor access
cover.
2. Lift rotor access cover and expose rotor.
3. Measure the amount of clearance between
chipping blade and chipping anvil from inside the
housing.

4. Loosen the three 1/2" bolts that hold the chipper
anvil to the frame. The bolts are accessed
underneath the feed roller. (See Figure 9).

5. Adjust anvil inward or outward to the correct
clearance. Check how all blades clear the anvil.
