SAFETY RULES

_ WARNING: TO REDUCE THE POTENTIAL FOR ANY INJURY, COMPLY WITH THE FOLLOWING

TRAINING

• Read this owner's manual carefully in its entirety before attempting to assemble or operate this machine. Be com- pletely familiar with the controls and the proper use of this machine before operating it. Keep this manual in a safe place for future and regular reference and for ordering replacement parts.

• Children must never be allowed to operate this equipment.

• No one should operate this unit while intoxicated or while

taking medication that impairs the senses or reactions.

• This equipment should never be operated in the vicinity of children, pets or other persons.

• Never run your machine in an enclosed area as the exhaust from the engine contains carbon monoxide, which is an odorless, tasteless and deadly poisonous gas.

• Never place your hands or any part of your body or cloth- ing inside the feeding chamber, discharge chute, or near any moving part while the machine or engine is running.

• If it is necessary for any reason to inspect or repair the

feeding chamber or any part of the machine where a mov-

ing part can come in contact with your body or clothing,

stop the machine, allow it to cool, disconnect the spark

plug wire from the spark plug and move it away from the

spark plug before attempting such inspection or repair.

PREPARATION

• Wear safety glasses provided with your unit while operat- ing the chipper-shredder to prevent injury from any mate-

rial which may be ejected out of the openings.

• Wear proper apparel. Avoid wearing loose fitting clothing.

Wear gloves when handling material.

• HANDLE GASOLINE WITH CARE as it is an extremely

flammable fuel.

• Check the fuel before starting the engine. Do not fill the

fuel tank indoors, while the engine is running, or while the engine is still hot. Turn the unit off and let the engine cool before refueling.

• Fuel your chipper-shredder in a clean area. Do not

smoke while refueling.

• Fuel tank cap must be secure at all times except during refueling.

• Avoid spilling gasoline or oil. Wipe the unit clean of any

spilled fuel or oil.

• Store fuel and oil in approved containers, away from heat

or open flame, and out of reach of children.

• This machine should be operated only upon a level surface.

• Assure that all screws, nuts and bolts and other fasteners

are properly secured.

OPERATION

• When feeding shreddable material into this equipment,

be extremely careful that pieces of metal, rocks, bottles, cans or other foreign objects are not included. Personal injury or damage to the machine could result.

SAFETY INSTRUCTIONS. FAILURE TO COMPLY WITH THE INSTRUCTIONS MAY RESULT IN

PERSONAL INJURY.

If the cutting mechanism strikes any foreign object or if your machine should start making an unusual noise or

vibration, immediately stop the engine, disconnect the

spark plug wire from the spark plug and move it away from the spark plug. Allow the machine to stop and take the following steps:

Inspect for damage.

Replace or repair any damaged parts. Check for any loose parts and tighten to assure contin-

ued safe operation.

• The engine must be kept clean of debris and other accu- mulations.

• Do not allow an accumulation of processed material to build up in the discharge area as this will prevent proper

discharge and can result in kick-back from feed opening.

• Never place your hands or any other part of your body or clothing inside the feeding chamber, discharge chute or near any moving part while the engine is running.

• Keep all guards and deflectors in place and in good work- ing condition to assure continued safe operation.

• Always stand clear of the discharge area when operating this machine.

• Keep your face and body back from the feed opening to

avoid accidental bounce back of any material.

• Do not over-reach. Keep proper balance and footing at all times.

• The engine governor settings on your machine must not be altered, changed, or tampered with. The governor controls the maximum safe operating speeds and pro- tects the engine and all moving parts from damage caused by overspeed.

• Do not transport machine while engine is running.

• Do not operate engine if air cleaner or cover directly over carburetor air intake is removed, except for adjustment. Removal of such parts could create a fire hazard.

MAINTENANCE AND STORAGE

• When this equipment is stopped for servicing, inspection, storage or to change an accessory, make sure the spark plug wire is disconnected from the spark plug and moved away from the spark plug. The machine should be allowed to cool down before making such inspection, adjustments, service, etc. Maintain your machine with care and keep it clean for the best and continued safe

operation.

• Do not use flammable solutions to clean the air filter.

• When not in use, your machine should be stored out of the reach of children. Keep where gasoline fumes will not reach an open flame or spark. For long periods of stor- age, refer to the "Storage" section of this manual.

HOW TO USEYOUR CHIPPER-SHREDDER

Do not attempt to shred or chip any material other than vegetation found in a normal yard (i.e., branches, leaves, twigs, etc.).

WARNING: THE CHIPPER-SHREDDER

,_ DISCHARGES MATERIALS WITH CONSID-

The chipper-shredder is designed for two different

methods of operation.

• Leaves and small branches up to 1/2" diameter

(recommended) or 1" diameter (maximum) can be fed into the hopper assembly. See figure 5. If it

becomes necessary to push material into the chip-

per-shredder, use a small diameter stick--NOT YOUR HANDS. The stick should be small enough that it will be ground up if gets into the impeller assembly.

ERABLE VELOCITY. KEEP AWAY FROM

THE AREA AROUND THE CHUTE

DEFLECTOR. ALWAYS STOP THE ENGINE AND DISCONNECT THE SPARK PLUG WIRE WHEN REMOVING OR

ATTACHING THE BAG, WHEN CHANGING CONTAINERS OR WHEN REMOVING THE

SHREDDED MATERIAL. WEAR SAFETY GLASSES AND GLOVES WHENEVER USING YOUR CHIPPER-SHREDDER.

WARNING: DO NOT PUT MATERIAL

LARGER THAN 1/2" IN DIAMETER (REC- OMMENDED) or 1" DIAMETER (MAXI- MUM) INTO THE HOPPER ASSEMBLY.

MATERIAL UP TO A MAXIMUM OF 3" IN DIAMETER MATERIAL MAY BE FED INTO THE CHIPPER CHUTE. DO NOT

ATTEMPT TO SHRED OR CHIP ANY MATERIAL LARGER THAN 3" IN DIAME- TER. PERSONAL INJURY OR DAMAGE TO THE MACHINE COULD RESULT.

IMPORTANT: There is a flail screen located inside the housing in the discharge area. If the flail screen

becomes clogged, remove and clean as instructed in the Service and Adjustments section. For best per-

formance, it is important to keep the shredding blade and the chipper blades sharp. If the composition of

the material being discharged changes (becomes

stringy, etc.) or if the rate at which the material is dis- charged slows clown considerably, it is likely that the shredding blade and/or chipper blades are dull and

need to be sharpened or replaced. Refer to Service and Adjustments section.
