1.1 SAFETY ALERT SYMBOL

1.2 EMISSION INFORMATION

The Owner/Operator’s manual uses this symbol to alert you of potential hazards. Whenever you see this symbol, read and obey the safety message that follows it. Failure to obey the safety message could result in personal injury, death or property damage.

DANGER

Indicates an imminently hazardous situation that, if not avoided, will result in death or serious injury.

WARNING

Indicates a potentially hazardous situation that, if not avoided, could result in death or serious injury.

CAUTION

Indicates a potentially hazardous situation that, if not avoided, may result in minor or moderate injury.

Under California Law and the laws of several other states, you are not permitted to operate an internal combustion engine using hydrocarbon fuels on any forest covered, brush covered or grass covered land or on land covered with grain, hay or other flammable agricultural crops, without an engine spark arrester in continuous effective working order.

The engine on your power equipment, like most outdoor

power	equipment, is
an internal combustion
engine		that	burns
gasoline		or	diesel
fuel	(hydrocarbons).
Therefore,		your	power
equipment		must	be
equipped		with a	spark
arrester		muffler	in
continuous		effective

working order. The spark arrester must be attached to the engine exhaust system in such a manner that flames or heat from the system will not ignite flammable 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 local fire marshal or forest service for specific information about which regulations apply in your area.

Thestandardmufflerinstalledontheengineisnotequipped with a spark arrester. One must be added 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.

3 Features & Controls

Section

Understanding how your machine works will help you achieve the best results when using your machine. The following descriptions define the features and controls of your machine.

engagement handle

During engine start-up, the engagement handle must be in the disengaged position (Figure 3.1). With engine at full throttle, carefully engage the rotor by slowly pushing the engagement handle down, allowing the rotor to speed up gradually (Figure 3.2). Engaging the clutch too quickly with the engine at full or half throttle will bog down the engine and will shorten the life of the belt. To disengage the rotor, first idle the engine down and then lift the engagement handle up

shredder chute

Materials to be shredded are fed through the shredder chute to the shredder knives.

chipper chute

Materials to be chipped are fed through the chipper chute to the chipper blades.

jack stand

4 4 Operation

Section

As with any other piece of outdoor equipment, getting the feel for how your machine operates and getting to know the best techniques for particular jobs are important to overall good performance.

CHIPPING OPERATION

The chipping operation takes place on the front of the machine, where hardened steel chipper blades are mounted on a rotating disk assembly. Material fed into the chipper chute is sliced into small chips and propelled out through a discharge tube.

Shredding OPERATION

In this operation, hardened steel shredder knives grind up material fed into the shredder chute. The shredded material then leaves the shredder area by traveling through the discharge screen. The shredded material can be diverted into a container or onto the ground.

WARNING

Move machine to a clear, level area outdoors before starting. Do not operate in the vicinity of bystanders. Make sure cutting chamber is empty before starting.

WARNING

Before operating your machine, be sure you read and understand all safety, controls and operating instructions in this owner's manual and on your machine. Failure to follow these instructions can result in serious injury or property damage.

4.1Starting recoil models

1.Check engine oil level before starting.

2.Place the throttle control midway between the slow and fast positions.

3.Place the choke control into the choke position.

4.Turn the key switch to on (if equipped).

5.Pull the recoil starter until the engine starts. Make sure the starting cord retracts.

6.Move throttle to full position.

7.Slowly push the engagement handle down to engage the chipper/shredder.

For a Cold Engine — Gradually return the choke control to the off position after the engine starts and warms up. The machine may be operated during the warm up period, but it may be necessary to leave the choke partially on until the engine warms up.

For a Warm Engine — Return choke to the off position as soon as engine starts.

4.2 Starting electric models

Do not crank the engine continuously for more than 10 seconds at a time. If the engine does not start, allow a

60 second cool down period between starting attempts.

Failure to follow these guidelines can burn out, or permanently damage, the starter motor.

If the engine develops sufficient speed to disengage the starter but does not keep running (a false start), the engine rotation must be allowed to come to a complete stop before attempting to restart the engine. If the starter is engaged while the flywheel is rotating, damage to the starter may result.

If the starter does not turn the engine over, shut off starter immediately. Do not make further attempts to start the engine until the condition is corrected. Do not jump start using another battery. Follow the steps below to start the machine.

1.Check engine oil level before starting.

2.Place the throttle control midway between the slow and fast positions. Place the choke control into the choke position.

3.Start the engine by activating the key switch. Release the switch as soon as the engine starts.

4.Move throttle to full position.

5.Slowly push the engagement handle down to engage the chipper/shredder.

6.For a Cold Engine — Gradually return the choke control to the off position after the engine starts and warms up. The machine may be operated during the warm up period, but it may be necessary to leave the choke partially on until the engine warms up.

For a Warm Engine — Return choke to the off position as soon as engine starts.

4.4operating the chipper/shredder

WARNING

Read and follow all safety instructions in this manual.

Failure to operate the machine in accordance with the safety instructions MAY RESULT IN PERSONAL

INJURY!

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 a long-sleeved shirt.

Use common sense and practice safety to protect yourself from branches, sharp objects, and other harmful objects.

The machine chips and shreds 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 3 inches (7.5 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.Material fed into the shredder chute must be ¾ inches (2 cm) in diameter or less. Common shredding materials include grass, leaves, garden refuse, sticks, and small branches.

4.Exclude pieces of metal, rocks, bottles, cans, and other foreign objects when feeding material into the machine.

5.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.

6.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.

7.If the engine slows to where it may stall, stop feeding material and allow the engine to recover. Feed material more evenly.

8.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.

WARNING

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

Never use shovels or forks to feed brush. They can cause extensive damage if they contact the blades. In addition, metal pieces can be ejected from the chipper chute and cause serious injury or death.

Never feed brush into the chute with your feet.

Never use hands or feet to clear materials that build up in the chute.

9.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.

10.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.

11.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.

WARNING

To prevent personal injury or property damage: shut off engine and make sure that all moving parts have come to a complete stop before, servicing, adjusting or repairing. Disconnect the battery and remove ignition key where applicable.
