Safety Instructions

This chipper is designed and tested to offer reasonably safe service. However, failure to operate it in accordance with the following safety

instructions MAY RESULT IN PERSONAL IN-

JURY!

Before Operating

1. Become familiar with the owners manual before attempting to operate this equipment. See engine owners manual for additional safety information.

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.

secured. Once every 10 hours of operation, all screws, nuts, bolts, and other fasteners should be checked for proper tightness to insure everything is in proper working condition.

Operation

One of the critical moments in job safety, as well as chipper safety, is setting up your chipping site so you are not endangered by traffic and the public is not endangered by your work. Great care must be taken to provide adequate warning by way of signage and coning, if it is necessary to divert vehicle or pedestrian traffic.

A well-prepared traffic plan should include parking off the highway whenever possible. The work area should be coned off as soon as the chipper vehicle is stopped. A void sudden traf fic stoppage or lane diversion. Do not allow pedestrians to walk through the work area. Make sure chips or dust do not blow into traffic, parked cars, or pedestrians.

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

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

Preparation

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

2. A void wearing loose-fitting clothing. Never operate this machine wearing loose clothing particularly if it has drawstrings which could wrap around or get caught in the machine.

3. Operate the machine only on a level surface. 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.

4. Before starting the machine, visually check that all screws, nuts, bolts, and other fasteners are properly

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 come to a complete stop. After machine stops:

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

4. Every 10 hours of operation, check the bolts on the following for correct torque (75 ft. lbs.):

• Hydraulic feed roller bearing

• Hydraulic motor mounting

• Chipper rotor bearing

• Chipper blades

• Rotor paddles

• Chipper anvil

ECTION

Failure to maintain proper fastening torque (75 ft. lbs.) on bolts for the components listed above may result in severe damage to the chipper and/or personal injury .

5. 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.

6. Do not attempt to operate the chipper with any of the guards, deflectors, or shrouds removed. Keep away from moving parts.

7. Keep all guards, deflectors, and shrouds in good working condition.

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

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

10. Do not overreach. Keep proper balance and footing at all times.

1 1. Do not transport or move machine while the ma-

chine is running.

12. If the machine becomes clogged, shut off engine. Allow machine to come to a complete stop before clearing debris.

Additional Safety Rules for Towing

1. Before towing, rotate the discharge tube to face in the opposite direction of the vehicle that is towing it.

This will prevent the discharge tube from projecting over the trailer wheels and striking foreign objects.

2. Always connect hitch safety chains. Make sure

trailer hitch bolts are tight and secure. Do not attempt to attach the pintle hitch to a ball type vehicle hitch.

3. Maximum towing speed should not exceed 55 M.P.H. Inflate tires to manufactures specs. as stated on the tire sidewall. Check wheel lug bolts periodically to be sure they are tight and secure.

4. 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.

5. Never allow passengers to ride on the infeed chute while the vehicle is moving, whether the chipper is running or not.

Maintenance and Storage

1. When this equipment is stopped for servicing, inspection, storage, or to change an accessory, make sure that the key is removed from key switch. Disconnect battery.

2. Store the machine out of the reach of children and where fuel vapors will not reach an open flame or spark. For storage periods of three months or more, drain the fuel and dispose of it in a safe manner. Always allow the machine to cool before storing.

The Standard muffler installed on the

chipper engine does not include a spark arrestor. If this machine is to be used in an area where a spark arrestor is required by law, one will have to be added before use. Contact the local authorities to see if these laws apply to you. See your authorized engine dealer for spark arrestor options.
