Inspecting the Chipper Knife and Wear Plate
Routine inspection of the Chipper Knife and Wear Plate will ensure that your DR 16.50 FTP PRO Rapid
Feed Chipper is operating at full efficiency (see “Regular Maintenance Checklist” at the beginning of this
Chapter). Operating with a worn or damaged Chipper Knife or Wear Plate will cause extreme stress and
vibration to the machine and make chipping difficult for the operator.
VISUAL INSPECTION OF THE CHIPPER KNIFE (before each use)
Tools Needed:
• 5/16" Wrench
1. Remove the four Screws that secure the Front Access
Cover with a 5/16" wrench and remove the Access
Cover (Figure 33).
2. Rotate the Flywheel with a long stick until the Knife is
visible.
3. If the Knife has visible nicks or damage it must be
sharpened or replaced (see “Removing and Replacing
the Chipper Knife” in this chapter).
4. If the Knife does not appear to have any damage,
replace the Access Cover and secure with four Screws
using a 5/16" wrench.
VISUAL INSPECTION OF THE CHIPPER KNIFE AND WEAR PLATE (every 8-10 hours)
Tools Needed:
• Two 1/2" Wrenches
1. Have someone support the Hopper as you use two
1/2" wrenches to remove the six Bolts, Washers and
Locknuts that support the Hopper to the Chipper
Assembly (Figure 34).
2. Remove the Hopper from the Chipper Assembly.
3. Use a stick to rotate the Flywheel until the Knife is next
to the Wear Plate.
