3. a. Remove the chipper chute support brace from the
frame by removing the two hex bolts and saddle
washers which secure it. See Figure 9.
b. Remove the chipper chute by removing three hex
nuts and washers which secure it to the impeller
housing. See Figure 9.
• Rotate the impeller by hand until one of the two
chipper blades is visible through the impeller
housing opening.
c. Remove the blade by removing the internal hex
screws, lock washers and hex nuts which secure it
to the impeller. Retain the hardware.
NOTE
: Use a 3/16” hex key (Allen) wrench on the outside
of the blade and a 1/2” box (or socket) wrench on the
inside of the impeller. Hold the Allen wrench stationary
and rotate the box (or socket) wrench to loosen the nut.

by using gloves. Follow the original angle of grind and
make sure to remove an equal amount from each blade.

guide to impeller housing. See Figure 11.
• Carefully separate the hopper assembly from the
impeller housing and set it aside.
• Insert a piece of wood into the chute deflector
opening to stabilize the impeller and prevent it from
rotating when removing the shredder blade.
b. Remove the two internal hex screws, hex lock nuts,
and lock washers which secure the shredder blade
to the impeller. See Figure 11.

the original angle of grind as a guide. Make certain each
cutting edge receives an equal amount of grinding to
prevent an unbalanced blade. Remove metal from the
heavy side until it is balanced evenly.
