RAPID-FEED™ CHIPPER
• Take the Chipper Knife to a machine shop for proper sharpening.
• How many times a Knife can be sharpened is determined by how much material needs to be taken
off to sharpen or to compensate for dents or gouges.
• A new Chipper Knife has 1.579" measurement between the short side bevel edge and the Knife Top
Edge (Figure 43 “New Knife”).
• The knife should never be sharpened to the extent that more than 3/32" is taken off this
measurement.
• Once this measurement is below 1.485" (see Figure 43 “Sharpened Knife”), or if you are unable to
remove dents or gouges with these guidelines, replace the Knife.
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 44).
NOTE: If the Wear Plate is filed enough times that the proper
gap between the Knife and Wear Plate can not be set with the
Gap Gauge, You will need to replace the Wear Plate.
