Shredder Hopper: The shredder hopper is on top f the unit. Leaves and other light waste can be loaded into the shredder hopper. NEVER insert hands into the hopper .

Debris Bag: Use the debris bag to collect the material discharged from the unit. Do not operate the unit without the debris bag on place.

Operation

General Operating Safety

Be sure to read all information in the Safety and

Operation sections before attempting to operate this unit.

Become familiar with all of the controls and how to stop the unit.

Upon start-up and shut-down, you may hear the metalto-metal sound of the triangular hammers and Jhammers positioning themselves on the rotor. This is normal. If this sound continues after the machine has reached full speed, contact your dealer for an inspection of the unit. Overloading the equipment will shorten its life, and can cause mechanical failures.

Chipper Operation

The chipper is designed to handle tree limbs and branches up to approximately 3” (7,6 cm) in diameter.

The chipping knives also permit the processing of course organic matter like corn stalks. Tree branches must be inserted large-end first into the chipper cone. Since occasional kick-backs may occur, always stand off to the side of the unit. Allow the self-feeding action of the unit to draw the sticks in.

Shredder Operation

The shredder is designed to shred light brush, leaves, and other soft but bulky organic waste. As material is loaded into the shredder hopper it is pulled into path of the triangular and J-hammers by air flow.

Vacuum Attachment (Optional)

DANGER

The exhaust from this product contains carbon monoxide gas. Carbon monoxide is a colorless, orderless, and tasteless gas that can cause dizziness, nausea, unconsciousness, or even brain damage and death if inhaled for prolonged periods.

Operate the unit outdoors in a well ventilated location only. Keep children, pets, and bystanders away.

Failure to follow these instructions may result in serious injury or death.

Adding Fuel

Do not use gasoline containing METHANOL, gasohol containing more than

10% ETHANOL, gasoline additives, or white gas because engine/fuel system damage could result.

WARNING

To avoid serious personal injury from rotating cutting blades, keep hands out of inlet while machine is running.

In addition to the chipper cone and hopper, loose debris may be processed by the Vacuum hose adapter kit.

Leaves may be raked directly into the leaf tray where vacuum action will draw them into the shredder. For hard-to-reach areas, the nozzle and hose assembly may be used. The strength of the Vacuum may be changed using the rotating sleave on the nozzle.

Operating Location

Select an area with firm, level ground, covered by dirt or grass. Do not operate on wet or slick surfaces, or near bystanders. Locate and organize the materials to be processed so that you don’t have to walk in front of the inlet or discharge openings, and so you have adequate room to work safely.

WARNING

Gasoline is highly flammable and must be handled with care. Never fill the tank when the engine is still hot from recent operation. Do not allow open flame, smoking or matches in the area. Avoid over-filling and wipe up any spills.

To add fuel:

1. Remove the fuel cap (see Figure 1).

2. Fill the tank. Do not overfill. Leave room in the tank for fuel expansion. Refer to your engine manual for specific fuel recommendations.

3. Install and hand tighten the fuel cap.

10

Starting the Engine

1. Set the throttle to FULL.

2. Close the choke.

NOTE: A warm engine may not require choking.

3. Place one foot on the front support leg to hold the unit firmly in place.

4. Pull the starting rope out to begin turning the engine over. Pull slowly at first and increase speed with each successive pull.

5. After the engine starts, open the choke and move the engine throttle control to SLOW. Warm up the engine by running it for at least a minute.

8. Set throttle to FULL and begin chipping/shredding.

Stopping the Engine

NOTE: In the event of an emergency the engine can be stopped by setting the throttle control to STOP.

1. Slide the throttle control fully left to the STOP position.

NOTE: Upon start-up and shut-down, you may hear the metal-to-metal sound of the triangular hammers and Jhammers positioning themselves on the rotor. This is normal.

2. After the engine has stopped moving, remove the spark plug wire and remove any debris from the unit and engine.

Processing Materials

Most materials to be processed can be handled more efficiently by following these tips.

Chipping Tips:

• Prune branches down close to the main branch to make feeding them into the chipper cone easier.

• Large, hard, dried tree branches that resist chipping can be processed by rotating them as you alternately insert and retract them.

• If the material to be chipped is extremely hard, kicks back forcefully when being fed into the chipper cone, or cannot be easily controlled, remove the material immediately and set it aside.

• If additional force is required to insert materials into the chipper, the blades probably need to be sharpened. Consult the Troubleshooting and Repair section of this manual, or see your authorized dealer.

• Maintain control of the materials you are feeding to prevent them from whipping around.

• Do not insert short pieces of material into the chipper cone by hand. Use a larger piece of material to force them into the chipper cone.

Shedding Tips

• Don’t overload the shredder by dumping large volumes of material into the hopper opening.

• Alternate loads of wet and dry material to prevent the discharge from becoming plugged.

• Never use any object to force material into the shredding chamber. It could get caught in the shredding hammers and damage the unit.
