the engine on your power equipment, like most outdoor power equipment, is an internal combustion engine that burns gasoline (a hydrocarbon fuel). therefore, your power equipment must be equipped with a spark arrester

mufer in continuous effective working order. The spark

arrester must be attached to the engine exhaust system

in such a manner that ames or heat from the system will not ignite ammable material.

Failure of the owner/operator of the equipment to comply with this regulation is a misdemeanor under California law and may also be a violation of other state and/or federal regulations, laws, ordinances, or codes. Contact your lo-

cal re marshal or forest service for specic information

about which regulations apply in your area.

The standard mufer installed on the 13 HP Honda engine is equipped with a spark arrester. The mufer

installed on the 20 hP honda engine is noT equipped with a spark arrester. one must be added to the 20 hP

engine mufer before using this machine in an area

where a spark arrester is required by law. Contact the local authorities if these laws apply to you. See your authorized engine dealer for spark arrester options.

cauTion

obtain and wear safety glasses at all times when operating the machine. do not wear loose fitting clothing. the operator should always wear heavy boots, gloves, pants and shirt. use common sense and practice safety

to protect yourself from branches, sharp objects, and other harmful objects.

2. Select limbs that are up to 4 inches in diameter. trim side branches that cannot be bent enough to feed into the chipper chute. Small diameter branches can be held together in a bundle and fed in simultaneously.

3. 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 depends on the type of material fed and the sharpness of the cutting blades.

4. Never lean over the chute to push objects into the cutting device. use a push stick or brush paddle.

5. never use shovels or forks to push brush. they can go through the chipper, are expensive to replace, and

cause major damage. In addition, metal pieces can be shot back like shrapnel to injure or kill the operator or

bystanders.

6. Feed brush from the side of the chute, rather than from the front. then, step back to avoid being hit by the brush moving into the chipper.

7. never push brush into the feed chute with your feet.

8. Stop the material feeding and allow the engine to recover if the engine slows to where it may stall.

9. 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.

10. Chipping dead, dry material will create heat and dull the chipping blades quickly. alternate greener material with dry material to lubricate the chipping blades for longer life and better performance. When the chipping blades become dull, they will require sharpening. Refer to the Service and Maintenance section for more information on sharpening blades.

Warning

do not leave machine unattended. do not inspect, or service the machine unless the engine is stopped and the spark plug is disconnected from its wire.

the chipper is designed to chip a variety of materials into a more readily decomposing or handled condition. the following guidelines can be used to help you get started:

SERVICE & MAINTENANCE

Warning

Before inspecting or servicing any part of the machine, shut off power source, disconnect spark plugs, and make sure all moving parts have come to a complete stop. the chipping blades are sharp! use care when

working on machine to avoid injury.

4.2 SharPening chiPPer bladeS

chiPPing blade SharPening TiPS

poor chipping performance is usually a result of dull chipping blades. If your chipper's performance has decreased, check for the following symptoms:

• Severe vibration when feeding material into the chipper.

• Small diameter branches do not self-feed.

• Chips discharge unevenly or have stringy tails–especially when chipping green branches.

the chipper blades will eventually become dull, making chipping difficult. It is recommended that the chipper blades are sharpened every 5-15 hours of chipper operation. to remove the chipping blades for sharpening:

1. Remove the retaining bolt that holds the access cover (see Figure 4.1) to the main frame assembly.

2. tilt access cover over to allow rotor access. Rotate the rotor so that the bolts holding a chipping blade are most accessible.

3. Remove the two 5/16" bolts holding the chipper blade. Repeat for all four blades. the four chipping blades have two edges per blade and can be reversed one time each before sharpening. If both sides have not been used, remove and reverse the chipping blades. Reinstall chipping blades and proceed with chipping.

to grind the angled edge of the chipping blade to 45 degrees (see Figure 4.2): grind the blades on a slowspeed wet grinder if possible, or have them sharpened by a professional. If you use a bench grinder, be careful when grinding so that the blade material does not get too hot and change color–this will remove the blade's special heat treated properties. use short grinding times and cool with water. try to remove an equal amount from each blade to maintain balance. Replace the chipping blades and tighten

bolts to 25 ft-lbs. Close cover and replace bolt.

Before you sharpen the chipping blades, check for permanent damage. Replace the blade if:

• the blade is cracked (especially around the bolt holes) or the edges are too deeply chipped to be ground smooth.

• the base of the cutting edge is worn or has been resharpened so that it is too close to the rotor chipping slot.

Figure 4.2, Sharpening the chipper blades

4.3 SeTTing blade clearance

the four-edged chipping anvil located directly behind the chipper chute (Figure 4.3) should clear the chipping blades

by 1/16 inch to 3/16 inch. The chipping anvil is adjustable

and reversible.

4.3 SeTTing blade clearance (conT.)

To adjust chipping anvil:

1. lift rotor access cover and expose rotor. loosen the two 1/2 inch bolts that hold the chipper anvil to the frame.

SERVICE & MAINTENANCE

Check belt tension and adjust if needed. The belt deflection at the center of the belt should be 7/16" when a 20 lb. load is placed against it (see Figure 4.6).

Reinstall belt guard.

depress belt engagement pedal, start engine, engage

drive belt, and test unit. Readjust pulleys if needed.

2. Measure the amount of clearance between chipping blade and chipping anvil from inside of housing.

3. Adjust inward or outward to desired measurement.

4. tighten bolts on chipping anvil to 75 ft-lbs. Make sure all blades clear the anvil by 1/16" to 3/16" before operating.

If the chipping anvil edge is damaged or worn unevenly, remove the two bolts holding the anvil and use one of the

other three edges. Adjust for correct measurement.

4.4 adJuSTing/rePlacing drive belT

Check the condition of the drive belt annually or after every 25 hours of operating, whichever comes first. If the belt is

cracked, frayed, or worn, replace it. To replace or adjust
