Wear Plate Sharpening
The Wear Plate edges can become rounded and chipped during use and must be squared off to ensure efficient operation.
Tools Needed:

Flat File

Straightedge
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 41).
3. Check with a Straightedge to ensure that the Wear Plate edge is flat and
straight.
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.
Removing and Replacing the Wheels
The Wheels on the DR SELF-FEEDING WOOD CHIPPER are pneumatic and have pressed in Bearings for easy transport. With
use, tires or Bearings may need replacing. The following procedures will explain the replacement procedures.
Tools and Parts Needed:

Large Flat Head Screwdriver

Cutting Pliers

Fine Tooth File

Soft Faced Hammer

Push Nut w/Cap
1. Jack up the side of the Chipper just until the Pneumatic Wheel is off the
ground.
2. Pry the Cap off the axle with a Flat Head Screwdriver (Figure 42).
3. Bend the Push Nut out with the Flat Head Screwdriver and cut it with
Cutting pliers so it can be pulled off the Axle.
4. Remove the Pneumatic Wheel from the Axle.
Note: There are spacers behind the wheel that must remain on the Axle when the
Pneumatic Wheel is replaced.
Note: File off any marks in the Axle if Wheel will not slide on easily.
5. Install the Pneumatic Wheel onto the Axle and against the Spacer with the
Valve side out.
6. Place a new Push Nut w/Cap over the Axle and tap it on with a Soft Faced
Hammer.
7. Check the Pneumatic Wheels for proper air pressure (see “Check the Tire
Pressure” in Chapter 2).
