Safety & Operating Instructions

VISUAL Inspection of the Chipper Knife (Before every use) and Wear Plate (minimum every 25
hours)
Routinely check the wear plate for a sharp square edge. Using a rounded or chipped wear plate will decrease
performance and cause excessive vibration that will cause damage to the GRAVITY SELF-FEEDING WOOD CHIPPER and
make chipping difficult for the operator.
Routinely check the chipper knife for sharpness. Using a dull knife will decrease performance and cause excessive vibration
that will cause damage to the GRAVITY SELF-FEEDING WOOD CHIPPER.

1. Remove the lowest four 5/16-18 x 3/4" Truss Head Bolts and thin Nylon
Locknuts that attach the Hopper Assembly onto the Hopper Neck from
each side of the Hopper Assembly (Figure 48).

(rounded) edges (Figure 49).
