SELF-FEEDING WOOD CHIPPER
Wear Plate Sharpening
The Wear Plate edges become rounded and chipped during use and must be
squared off to ensure efficient operation.
Tools Needed:
• Flat File
1. Secure the Wear Plate in a vise.
2. File the edge of the Wear Plate to take out any nicks and to square rounded
edges (Figure 59).
Note: If the Wear Plate is filed enough times that the proper gap between the Knife
and Wear Plate cannot be set with the Gap Gauge, you will need to replace the
Wear Plate.

Yard-Tow model has pressed in bearings for easy transport. The road tow
model has tapered bearings designed for highway use. With use, tires or
bearings may need replacing. The following procedures will explain the
replacement procedures.
