OPERATION
4.3 operaTInG THe CHIpper
The machine chips a variety of materials into a more readily decomposed or handled condition. The following guidelines
will help you get started.
1. run unit at full operating speed before starting to chip material.
2. limbs fed in to the chipper chute must be 4 inches 10 cm) in diameter or less. Trim side branches that cannot
be bent enough to feed into the chipper chute. Hold small diameter branches together in a bundle and feed in
simultaneously.
3. exclude pieces of metal, rocks, bottles, cans, and other foreign objects when feeding material into the
machine.
4. Feed brush from the side of the chipper chute, rather than from the front. Step aside to avoid being hit by the
brush moving into the chipper.
5. place limb, butt end first, into the chipper chute until it contacts the chipper blades. The actual feed rate of
the limb into the chipper will depend on the type of material fed and sharpness of the cutting blades.
6. If the engine slows to where it may stall, stop feeding material and allow the engine to recover. Feed material
more evenly.
7. If the chipper jams, remove the branch and rotate it before reinserting it into the chute. Alternately insert and retract
the limb or insert continuously at a rate that will not kill the engine.
8. Do not use the clutch to clear a plugged rotor. This may cause belt damage. Refer to the instructions for clearing
a plugged rotor in the service and Maintenance section.
9. alternate greener material with dry material to lubricate the chipping blades for longer life and better performance.
Chipping dead, dry material will create heat and dull the chipping blades quickly.
10. sharpen the chipping blades periodically. Check the sharpness of the blades every 5-15 hours. Refer to the
Service and Maintenance section for sharpening instructions.
