EMISSION INFORMATION
WARNING
WARNING TO ALL CALIFORNIA AND OTHER STATES OPERATING OUTDOOR POWER EQUIPMENT
Under California Law and under the laws of several other states you are not permitted to operate an internal combustion engine using hydrocarbon fuels on any forest covered, brush covered or grass covered land or on land covered with grain hay or other
flammable agricultural crop, without an engine spark arrester in continuous effective working order.
The engine on your power equipment, like most outdoor power equipment, is an internal combustion engine that burns gasoline, a hydrocarbon fuel. Therefore, your power equipment must be equipped with a spark arrester muffler in continuous effective working order. The spark arrester must be attached to the engine exhaust system in such a manner that flames or heat from the system will not ignite flammable material.
Failure of the owner/operator of the equipment to comply with this regulation is a misdemeanor under California law, and may also be a
violation of other state and or federal regulations, laws, ordinances, or codes. Contact your local fire marshal or forest service for specific information about what regulations apply in your area.
The standard muffler installed on the 25 HP engine is not equipped with a spark arrester. One must be added before use if this machine is intended to be used in an area where a spark arrester is required by law. Contact the local authorities if these laws apply to you. See your authorized engine dealer for spark arrester options.

Safety
BEFORE OPERATING
13.Use only in daylight or good artificial light.
14.Never use without proper guards in place.
15.Wear safety glasses at all times while operating this machine. One pair of safety glasses is provided.
16. Avoid wearing loose fitting clothing. Never operate this machine wearing clothing with drawstrings that could wrap around or get caught in the machine.
17.Check that all screws, nuts, bolts, and other fasteners are properly secured before starting the machine. Check all screws, nuts, bolts, and other fasteners for proper tightness to ensure everything is in proper working condition once every 10 hours of operation.
18.Keep all guards, deflectors, and shields in place and in good working condition.
19.Do not transport or move machine while the machine is running.
OPERATION SAFETY
1. Do not allow hands, or any part of body or clothing, inside the feeding chamber, discharge chute, or near any moving part.
DANGER
Keep hands, feet and clothing out of inlets and discharge openings while machine is operating to avoid serious personal injury.
WRONG
2.Check the cutting chamber to verify it is empty before starting the machine.
3.Exclude pieces of metal, rocks, bottles, cans, and other foreign objects when feeding chipable material into the machine.
4.Shut off engine immediately if the cutting mechanism strikes any foreign object or the machine starts making an unusual noise or vibrating. Allow the machine to stop completely. After machine stops:
A.Inspect for damage.
B.Replace or repair any damaged parts.
C.Check for and tighten any loose parts.
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.Stand clear of the discharge area when operating this machine.
7.Keep your face and body back from the feed opening.
WARNING
Material can kickup or shift suddenly and cause serious injury or death.
•Wear eye, and hearing protection.
•Stand to the side of the feed chute.
•Release and stand away from the material after feed roller starts pulling material into chipper or shredder.
8.Do not climb onto chipper shredder feed chutes or frame when operating. Do not overreach. Keep proper balance and footing at all times.
9.Keep the engine clear of debris and other accumulations.
WRONG
Bearcat Chipper Shredder Operator’s Manual |

Safety
10.Do not tamper with the engine governor settings on the machine; the governor controls the maximum safe operating speed and protects the engine and all moving parts from damage caused by over speed.
11.Setting up your chipping site so you are not endangered by traffic and the public is not endangered by your work is critical for safety. Take great care to provide adequate warning by way of signage and coning, if diverting vehicles or pedestrian traffic is necessary.
12. A well-prepared traffic plan includes parking off the highway whenever possible. Cone the work area as
soon as the vehicle is stopped. Avoid sudden traffic stoppage or lane diversion. Do not allow pedestrians to walk through the work area. Ensure chips or dust do not blow into traffic, parked cars, or pedestrians.
13. Check the bolts on the following for correct torque every 10 hours of operation:
1.Chipper shredder rotor assembly bearings (80 ft lbs).
2.Chipper blades (use 5/16” X 1” Grade 8 bolts) (20 ft lbs).
3.Shredder Knives (36 In lbs).
WARNING
Failure to maintain proper fastening torque (20 ft. lbs.) on chipper blade bolts may result in severe damage to the chipper and / or personal injury.
14.Shut off engine and allow machine to stop completely before clearing debris if the machine becomes clogged.
15.On electric start models, disconnect cables from battery before doing any inspection or service.
16.Rotate the discharge tube to face the opposite direction of the towing vehicle before towing. This prevents the discharge tube from projecting over the trailer wheels and striking foreign objects.
