Removing and Sharpening the Blade
•
Disconnect the spark plug wire and ground against the engine.
•
Remove chute and rotate the blade to align with the access hatch.
•
Remove the blade using an Allen key on the outside of the blade and an adjustable wrench on the impeller
assembly (through the discharge chute). Use a piece of pipe or wood to block the hammer blades, preventing
them from inadvertently turning.
•
Replace or sharpen the blade as desired.
•
When sharpening the blade, protect hands by using gloves.
NOTE: Make certain the blade is reassembled with the sharp edge facing upward.
Changing or Tightening the Belt
NOTE: The belt is designed to be the weakest link in the mechanical linkage between the engine and the
blade. This improves the safety and durability of the chipper/shredder.
Occasionally, changing or tightening the belt is required.
To change the belt:
•
Stop the engine and make certain the blades have come to a complete stop. Disconnect the spark plug wire
from spark plug and ground against the engine.
•
Remove the belt guard.
•
Loosen engine mount bolts and release belt tension.
•
Pry the belt off the pulley using a screw driver shaft as a wedge as you rotate the pulley.
•
Place a new belt on the pulleys in a similar fashion.
To tighten the tension on the pulleys, follow the above steps plus:
•
Scribe a mark on the base plate along the edge of the engine.
•
Remove the belt from the pulleys.
•
Remove the upper discharge chute and mulcher screen.
•
Loosen the four bolts securing the engine.
•
Slide the engine about 1/8" further back.
•
Tighten the engine mounting bolts securely.
•
Re-install the belt and verify the tension. If the belt is still too loose, move the engine back another 3mm by
repeating the above steps.
•
Reinstall guards and chute.
