SPARK ARRESTER WARNING TO RESIDENTS OF CALIFORNIA AND SEVERAL OTHER STATES

Under California law, and under the laws of several other states, you are not permitted to operate an inter­ nal combustion engine using hydrocarbon fuels on any forest, brush, hay, grain, or grass covered land; or land covered by any flammable agricultural crop with­ out an engine spark arrester in continuous effective working order.

The engine on the unit is an internal combustion engine which burns gasoline, a hydrocarbon fuel, and must be equipped with a spark arrester muffler in con­ tinuous 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 unit to comply with this regulation is a mis­ demeanor under California law (and other states) 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 informa­ tion about which regulations apply in your area.

6.Familiarize yourself with all safety and operating decals on this equipment and on any of its attachments or accessories.

7.Do not run engine in an enclosed area. Engine exhaust contains carbon monoxide gas, a deadly poison that is odorless, col­ orless, and tasteless. Do not operate this equipment near buildings, windows, or air conditioning equipment.

8.Do not put hands, feet, face, or any other part of your body or clothing near the chipper chute, shredder hopper, or discharge area. The cutting blades begin to rotate and build up speed once the engine is running and continue to rotate for some time after the engine is stopped. Serious personal injury will occur if con­ tact with the blades is made while they are rotating. Wait for all moving parts to stop completely.

9.Before inspecting or servicing any part of the equipment, shut off engine, make sure all moving parts have come to a complete stop, then disconnect spark plug wire from spark plug and move wire away from the plug.

Preparation

1.The operation of the unit can result in foreign objects being thrown by high speed rotating parts. Wear safety approved eye protection (with side shields) when using the unit.

2.Do not wear loose-fitting clothing, such as scarves, which could be caught by moving parts. Tie up or restrain long hair.

3.Make sure the unit is level and stable before starting the engine. Operate unit

only on level ground.

4.Do not operate unit on a paved, hard, or gravel surface. Discharged material may bounce from a hard surface and cause injury. Always operate unit on a level, earthen surface.

5.Each time before starting the unit, make a visual check to see that all screws, nuts, bolts and other fasteners are prop­ erly secured. The discharge screen (or

the optional bar grate), chipper chute and all safety covers must be correctly and securely installed. Disconnect spark plug wire and move it away from

spark plug before performing this check.

CHIPPER/SHREDDER FEATURES AND CDNTRDLS

SHREDDER HOPPER (INLET)

The shredder hopper (see Figures 3-1 and 3-1 A) is the opening at the top of the unit for material to be shredded. Material up to 1/2' in diameter can be processed through the shredder hopper. In the shredder chamber, rotating cutting blades shreS the material.

A rubber retainer flap (Figure 3-1 A) is installed at the shredder hopper opening. Material is pushed past this retainer flap (using only the leaf tamper supplied with unit) and enters the shredder

chamber. The retainer flap prevents kickback of materialsl Do not use the unit unless the retainer flap is securely fastened and is hanging freely inside the hopper opening. Immediately replace the retainer flap if it is torn or damaged.

A DANGER

Shredded particles can kick back up through the shredder hopper inlet. The retainer flap is designed to reduce kickback of particles and must be in place and securely fastened.

Perform maintenance and service only after the engine is off, the spark plug wire is disconnected and moved away from the spark plug, and all moving parts have come to a complete stop. Then use only a long wooden stick or a long handled shovel to clear away dis­ charged materials or blockages.

CHIPPER CHUTE (INLET)

Material up to 3" in diameter (such as small branches and vines) can be pro­ cessed through the side-mounted chipper chute (Figure 3-1). Material fed into the chipper chute is turned into chips by a chipper blade mounted on a revolving fly­ wheel (Figure 3-1A).

the holes in the screen determines how finely the materials are shredded.

CHIPPER/SHREDDER CHAMBER

Inside the chipper/shredder chamber is a flywheei/cylinder assembly that is beltdriven by the engine drive shaft.

The flywheel has a chipper blade (A, Figure 3-2) attached to one side. The cylinder assembly holds 12 shredder cutting blades

(B). During operation, the chipper blade and shredder blades revolve at the same time, allowing you to either chip or shred.

Material fed into the shredder hopper is shredded and ground when the shredder cutting blades force material against the chamber baffles and the discharge dis­ charge screen. When shredded finely enough, the material is forced out through the holes in the discharge screen (or between the bars of the optional bar grate).

The chipper cutting blade is separated from a stationary anvil by a gap of 1/16' to 1/8". Material fed into the chipper chute is

The unit comes equipped with a screen that has 3/4" holes. Optional screens having 3/8", 1" or 1-3/4" holes are avail­ able. The smaller holes produce more finely shredded particles. The larger holes produce more coarsely processed material and may not clog as readily when wet, soggy or green materials are processed. (A bar grate for processing very wet, heavy materials is also available). To remove and install a discharge screen, refer to Removal/lnstallation Discharge Screen or Bar Grate in Section 4.

IMPORTANT: Rotating shredder cutting blades pass within 1/4" of the discharge screen or bar grate. Keep hands and feet away at all timesi Never operate machine unless a discharge screen or bar grate is secureiy installed.

Figure 3-3: Standard discharge screen has 3/4" diameter holes.

BAR GRATE AHACHMENT (OPTION)

The bar grate attachment (Figure 3-4) has slotted openings that are wide enough to efficiently process wet or soggy materials such as matted leaves, spoiled or leftover vegetables, manure, etc. If desired, this coarsely shredded material can then be dried and later run through the shredder when a discharge screen is installed. To remove and install a bar grate, refer to

Removal/lnstallation Discharge Screen or Bar Grate in Section 4.

Figure 3-4: Optional bar grate.

CLUTCH LEVER

Use the clutch lever (Figure 3-5) when starting the engine. Engaging the lever releases tension on the cylinder assembly drive belt (Figure 3-6) to make engine starting easier.

When starting the engine, squeeze the clutch lever against the handlebar while pulling the recoil rope starter. Release the clutch lever slowly when the engine starts and is running smoothly. This action puts tension on the drive belt to rotate the shredder cylinder assembly.
