Safety Instructions for Operation

This chipper is designed and tested to offer reasonably safe service. However, failure to operate it in accordance with the following safety instructions MAY RESUL T IN PERSONAL INJUR Y!

Before Operating

Preparation

1. Become familiar with the owners manual before attempting to operate this equipment.

2. Do not allow children to operate this equipment.

3. Do not operate this equipment in the vicinity of bystanders.

4 . Carbon monoxide can be extremely dangerous in enclosed areas; do not run

the machine in an enclosed area. The exhaust from the engine contains carbon monoxide, which is colorless, odorless, and tasteless.

5. Do not allow hands, or any part of body or clothing inside the feeding chamber, discharge chute, or near any moving part.

6. Before inspecting or servicing any part of the machine, shut off the power source, disconnect the spark plug, and make sure all moving parts have come to a complete stop.

1. Obtain and wear safety glasses at all times while operating the machine. One pair of safety glasses is provided with each chipper.

2. Avoid wearing loose-fitting clothing.

3. Operate the machine only on a level surface.

4. Do not operate the machine on a paved, concrete, or hard gravel surface. Operating on a hard surface may cause discharged material to rebound and kickback. It will also cause increased machine vibration. Increased vibration may cause the machine to move and will promote premature wear of parts or loosening of fasteners.

5. Before starting the machine, visually check that all screws, nuts, bolts, and other fasteners are properly secured. Once every 10 hours of operation, all screws, nuts, bolts, and other fasteners should be checked with wrenches for proper tightness to insure everything is in proper working condition.

Operation

1. Before starting the machine, make certain the cutting chamber is empty .

2. When feeding chipable material into the machine, be extremely careful to exclude pieces of metal, rocks, bottles, cans, and other foreign objects.

3. If the cutting mechanism strikes any foreign object or if the machine should start making an unusual noise or vibration, immediately shut off the engine and allow the machine to stop.

a) Inspect for damage. b) Replace or repair damaged parts. c) Check for and tighten loose parts.

4. Do not allow processed material to build up in the discharge area; this may prevent proper discharge and can result in kickback of material through the feed opening.

Safety Instructions

Cont.

5. Do not allow hands or other part of the body or clothing inside the feeding

chambers, discharge chute, or near any moving part.

6. Keep all guards and deflectors in place and in good working condition.

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

8. Keep your face and body back from the feed opening.

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

10. Do not transport or move machine while the machine is running.

11. If the machine becomes clogged, shut off engine. Allow machine to come to a

complete stop before clearing debris.

Additional Safety

Rules for Towable

Models

Maintenance and

Storage for Towable

Models

1. Before towing, rotate the chipper chute opening to face in the opposite

direction of the vehicle that is towing it. This will prevent the chipper chute

from projecting over the trailer wheels and striking foreign objects.

2. Lock the rotor by inserting a bolt or punch through the locking holes on the side

of the rotor housing.

3. Use a 2 inch trailer ball, and always connect safety chains. Make sure trailer

hitch bolts are tight and secure.

4. Maximum towing speed should not exceed 55 MPH. Tire pressure should be 60

psi; check wheel lug bolts periodically to be sure they are tight and secure.

5. Make sure that the jack stand on trailer is in the UP position to clear the

ground during towing. Place the jack stand on a level surface and secure it in the DOWN position before use.

6. Shut off fuel supply to engine when towing.

1. When this equipment is stopped for servicing, inspection, storage, or to change

an accessory , disconnect the spark plug wire from the spark plug. Disconnect battery.

2. Store the machine out of the reach of children and where gasoline vapors will

not reach an open flame or spark. For storage periods of three months or more, drain the gasoline and dispose of it in a safe manner. Always allow the machine to cool before storing.
