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.

I4.  f it becomes necessary to push material through the 

shredder hopper, use a small diameter stick. Do not use 
your hands or feet.

I5.  f 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.

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.

3.  Before cleaning, repairing, or inspecting, stop the engine 

and make certain the impeller and all moving parts have 
stopped. Disconnect the spark plug wire and ground it 
against the engine to prevent unintended starting.

4.  Do not change the engine governor settings or overspeed 

the engine. The governor controls the maximum safe 
operating speed of the engine.

5.  Maintain or replace safety and instruction labels, as neces-

sary.

6.  Follow this manual for safe loading, unloading, transporting, 

and storage of this machine.

7.  Never store the machine or fuel container inside where 

there is an open flame, spark or pilot light such as a water 
heater, furnace, clothes dryer, etc.

8.  Always refer to the operator’s manual for proper instructions 

on off-season storage.

9.  If the fuel tank has to be drained, do this outdoors.
10. Observe proper disposal laws and regulations for gas, oil, 

etc. to protect the environment.

Do not modify engine

To avoid serious injury or death, do not modify engine in any 
way. Tampering with the governor setting can lead to a runaway 
engine and cause it to operate at unsafe speeds. Never tamper 
with factory setting of engine governor.
