Safe Handling of Gasoline:

To avoid personal injury or property damage use extreme care 

in handling gasoline. Gasoline is extremely flammable and the 

vapors are explosive. Serious personal injury can occur when 

gasoline is spilled on yourself or your clothes which can ignite.  

Wash your skin and change clothes immediately.

a.  Use only an approved gasoline container.
b.  Never fill containers inside a vehicle or on a truck 

or trailer bed with a plastic liner. Always place 

containers on the ground away from your vehicle 

before filling.

c.  When practical, remove gas-powered equipment 

from the truck or trailer and refuel it on the ground. 

If this is not possible, then refuel such equipment on 

a trailer with a portable container, rather than from a 

gasoline dispenser nozzle.

d.  Keep the nozzle in contact with the rim of the fuel 

tank or container opening at all times until fueling is 

complete. Do not use a nozzle lock-open device.

e.  Extinguish all cigarettes, cigars, pipes and other 

sources of ignition.

f. 

Never fuel machine indoors.

g.  Never remove gas cap or add fuel while the engine 

is hot or running. Allow engine to cool at least two 

minutes before refueling.

h.  Never over fill fuel tank. Fill tank to no more than ½ 

inch below bottom of filler neck to allow space for 

fuel expansion.

i. 

Replace gasoline cap and tighten securely.

j. 

If gasoline is spilled, wipe it off the engine and 

equipment. Move unit to another area. Wait 5 

minutes before starting the engine. 

k.  To reduce fire hazards, keep machine free of grass, 

leaves, or other debris build-up. Clean up oil or fuel 

spillage and remove any fuel soaked debris.

l. 

Never store the machine or fuel container inside 

where there is an open flame, spark or pilot light 

as on a water heater, space heater, furnace, clothes 

dryer or other gas appliances. 

Operation

1. 

Do not put hands and feet near rotating parts or in the 

feeding chambers and discharge opening. Contact with 

the rotating impeller can amputate fingers, hands, and 

feet.

2. 

Before starting the machine, make sure the chipper chute, 

feed intake, and cutting chamber are empty and free of all 

debris.

3. 

Thoroughly inspect all material to be shredded and remove 

any metal, rocks, bottles, cans, or other foreign objects 

which could cause personal injury or damage to the 

machine.

4. 

If it becomes necessary to push material through the 

shredder hopper, use a small diameter stick. Do not use 

your hands or feet.

5. 

If the impeller strikes a foreign object or if your machine 

should start making an unusual noise or vibration, 

immediately shut the engine off. Allow the impeller to 

come to a complete stop. Disconnect the spark plug wire, 

ground it against the engine and perform the following 

steps:

a.  Inspect for damage.
b.  Repair or replace any damaged parts.
c.  Check for any loose parts and tighten to assure 

continued safe operation.

6. 

Do not allow an accumulation of processed material to 

build up in the discharge area. This can prevent proper 

discharge and result in kickback of material through the 

feed opening.

7. 

Do not attempt to shred or chip material larger than 

specified on the machine or in this manual. Personal injury 

or machine damage could result.

8. 

Never attempt to unclog either the feed intake or discharge 

opening while the engine is running. Shut the engine off, 

wait until all moving parts have stopped, disconnect the 

spark plug wire and ground it against the engine before 

clearing debris. 

9. 

Never operate without the shredder hopper, chipper chute, 

or chute deflector properly attached to the machine. 

Never empty or change discharge bag while the engine is 

running. 

10.  Keep all guards, deflectors and safety devices in place and 

operating properly.

11.  Keep your face and body back and to the side of the 

chipper chute while feeding material into the machine to 

avoid accidental kickback injuries.

12.  Never operate this machine without good visibility or light. 
13.  Do not operate this machine on a paved, gravel or non-

level surface.

14.  Do not operate this machine while under the influence of 

alcohol or drugs.

15.  Muffler and engine become hot and can cause a burn. Do 

not touch.

16.  Never pick up or carry machine while the engine is running.
17.  If situations occur which are not covered in this manual, use 

care and good judgement. Contact Customer Support for 

assistance and the name of the nearest service dealer.

Maintenance & Storage

1. 

Never tamper with safety devices. Check their proper 

operation regularly.

2. 

Check bolts and screws for proper tightness at frequent 

intervals to keep the machine in safe working condition. 

Also, visually inspect machine for any damage and repair, if 

needed.
