Heavy Duty Power Equipment
Always stop engine, disconnect spark plug, and
ground against engine before cleaning,
lubricating or doing any kind of maintenance on
your machine.
Removing and Sharpening the Blade
The chipper was shipped with one blade attached and
one blade in the hardware bag. You can extend the belt
life by operating the chipper with a sharp blade.
 Disconnect the spark plug wire and ground against
the engine.
 Remove the blade access hatch and rotate the
blade to align with the access hatch.
 Remove the flail screen in the discharge chute by
removing the pins that secure it at the top and
bottom of the screen.
 Remove the blade using a 3/16” Allen wrench 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
flails, preventing them from inadvertently turning.
 Add, replace or sharpen the blade as desired.
 When sharpening the blade, protect hands by using
gloves and following the original angle of
grind.Torque to 250–300 in. lbs.
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 chipper/
shredder has 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:
Maintenance & Storage
 Scribe a mark on the base plate along the edge of
the engine.
 Remove the belt from the pulleys.
 Remove the handle, discharge chute and 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 1/8” by
repeating the above steps.
 Reinstall guards, chutes, and screens.
Cleaning the Chipper/Shredder
