Adjusting the Knife to Wear Plate Gap

Tools Needed:

• 7/16" wrench

• Gap Gauge (provided with Chipper)

1. To adjust the Wear Plate Gap, loosen the three

Nuts

on the Carriage Bolts with a 7/16" wrench just enough
so the Wear Plate will move but still have a slight
resistance. Now you can slide the Wear Plate up or
down (in or out) to achieve the correct gap setting
(Figure 40).

NOTE: See Figure 41 for a more detailed look at the

relationship of the Knife to Wear Plate.

2. Take the Gap Gauge and slide it between the Knife and

Wear Plate. Adjust the Wear Plate against the Knife
Gauge and tighten the Locknuts.

3. Check the adjustment as described in the “Checking

the Gap” in the previous section.

4. Position the Chipper Hopper into the Hopper Bracket

and secure with the six Bolts, Washers and Locknuts.

5. Re-connect the negative battery terminal wire (electric

start only) and the spark plug wire.

Chipper Knife Sharpening

• You should never attempt to sharpen the Chipper Knife

freehand.

• It is extremely important to consistently maintain the 40-

degree angle for proper performance (Figure 42).

• Excessive heat generated during the sharpening process

will damage Knives and weaken the metal. Be sure not to
overheat the Knife during sharpening because it will
shorten the life of the Knife.

NOISES, CLICKING OR VIBRATION. IF YOU DETECT ANY OF THESE, INSPECT THE MACHINE FOR
DAMAGE, OR ANY LOOSE PARTS. REPAIR OR REPLACE ANY DAMAGED PARTS AND TIGHTEN ANY
