DANGER: This machine was built to be operated according to the rules for safe operation in this
manual. As with any type of power equipment, carelessness or error on the part of the operator can
result in serious injury. This machine is capable of amputating hands and feet and throwing objects.
Failure to observe the following safety instructions could result in serious injury or death.

Training

1. Read, understand, and follow all instructions on the ma-

chine and in the manual(s) before attempting to assemble

and operate. Keep this manual in a safe place for future

and regular reference and for ordering replacement parts.

2. Be familiar with all controls and their proper operation.

Know how to stop the machine and disengage them

quickly.

3. Never allow children under 16 years old to operate this

machine. Children 16 years old and over should read and

understand the operation instructions and safety rules in

this manual and should be trained and super vised by a

parent.

4. Never allow adults to operate this machine without proper

instruction.

5. Keep bystanders, helpers, pets, and children at least

75 feet from the machine while it is in operation. Stop

machine if anyone enters the area.

6. Never run an engine indoors or in a poorly ventilated area.

Engine exhaust contains carbon monoxide, an odorless

and deadly gas.

7. 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.

8. Never attempt to unclog either the feed intake or

discharge opening, remove or empty bag, or inspect and

repair the machine while the engine is running. Shut the

engine off and wait until all moving parts have come to a

complete stop. Disconnect the spark plug wire and ground

it against the engine.

1. Thoroughly inspect the area where the equipment is to

be used. Remove all rocks, bottles, cans, or other foreign

objects which could be picked up or thrown and cause

personal injury or damage to the machine.

2. Always wear safety glasses or safety goggles during opera

tion or while performing an adjustment or repair, to protect

eyes. Thrown objects which ricochet can cause serious

injury to the eyes.

3. Wear sturdy, rough-soled work shoes and close-fitting

i. Never store the machine or fuel container inside where

there is an open flame, spark, or pilot light (e.g. furnace,

water heater, space heater, clothes dr yer, etc.)

j. To reduce a fire hazard, keep machine free of grass,

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

spillage and remove any fuel soaked debris.

k. Allow machine to cool at least 5 minutes before storing.

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.

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

your hands or feet.

5. 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 per form 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,
