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.

DESCRIPTION OF OPERATION

Understanding how your machine works will help you achieve the best results when using you Chipper Shredder. Read the following descriptions which define the operation of your machine.

CHIPPING OPERATION

The chipping operation takes place on the left side of the machine, where hardened steel chipper blades are mounted on a rotating rotor assembly . Material that is fed into the chipper chute is sliced into small chips which are then propelled out through a discharge chute which can be diverted into a container or onto the ground.

SHREDDING OPERATION

The shredding operation takes place on the rear of the machine, where hardened steel shredder knives grind up material that is fed into the shredder chute. The shredder adjuster lever, which can be adjusted to five settings, determines the chip size by keeping the chip in the shredder reservoir for a determined amount of time. The shredded material then leaves the shredder area by traveling through the discharge chute which can be diverted into a container or onto the ground.

ST ARTING TOW ABLE MODELS (FILLING THE T ANK)

DANGER

Gasoline is highly flammable and its vapors are explosive. T o prevent personal injury or property damage:

Store gasoline only in approved containers, in well ventilated, unoccupied buildings, away from sparks or flames. Do not fill the fuel tank while the engine is hot or running, since spilled fuel could ignite if it comes in contact with hot parts or sparks from ignition. Do not start the engine near spilled fuel. Never use gasoline as a cleaning agent.

FILLING THE FUEL T ANK

Fuel Type:

For best results use only clean, fresh, unleaded gasoline with a pump sticker octane rating of 87 or higher. In countries using the Research method, it should be 90 octane minimum. Purchase gasoline in small quantities and store in clean, approved containers. A container with a capacity of 2 gallons or less with a pouring spout is recommended. Such a container is easier to handle and helps eliminate spillage during refueling. DO NOT MIX OIL WITH GASOLINE.

Gasoline Alcohol blends

Gasohol (up to 10% ethyl alcohol, 90% unleaded gasoline by volume) is approved as a fuel for Kohler engines. Other gasoline/alcohol blends are not approved.

Gasoline Ether blends

Methyl Tertiary Butyl Ether (MTBE) and unleaded gasoline blends (up to a maximum of 15% MTBE by volume) are approved as a fuel for Kohler engines. Other gasoline/ether blends are not approved.

T o Add Gasoline.

1. Stop engine, wait for all parts to stop moving, and disconnect spark plug wire. Remove Key/T ool from key switch. Allow the engine and muffler to cool for at least three minutes.

2. Clean area around fuel fill cap and remove cap.

3. Using a clean funnel, fill fuel tank to 1/2-inch below bottom of filler neck to provide space for any fuel expansion. Install fuel fill cap securely and wipe up any spilled gasoline.

STARTING TOWABLE MODELS

Move machine to a clear, level area outdoors before starting. Do not operate in the vicinity of bystanders. Make sure cutting chamber is empty before starting.

1. Check engine oil level before starting.

2. Place the throttle control midway between the “slow” and “fast” positions. Place the choke control into the “on” position.

3. Depress the clutch pedal.

4. Start the engine by activating the key switch. Release the switch as soon as the engine starts.

Page 20 Bearcat Chipper Shredder Operator’s Manual

5. Move throttle to full position.

6. Slowly release the foot pedal to engage the chipper shredder.

NOTE:

Do not crank the engine continuously for more than 10 seconds at a time. If the engine does not start, allow a 60 second cool down period between starting attempts. Failure to follow these guidelines can burn out, or permanently damage, the starter motor.

NOTE:

Upon start up, a metallic ticking may occur. This is caused by the hydraulic lifter Ieakdown during storage. Run the engine for 5 minutes. The noise

will normally cease in the first minute. If noise continues, run the engine at mid-throttle for 20 minutes. If noise persists, take the engine to your local authorized Kohler Engine Service Dealer.

If the engine develops sufficient speed to disengage the starter but does not keep running (a false start), the engine rotation must be allowed to come to a complete stop before attempting to restart the engine. If the starter is engaged while the flywheel is rotating, the starter pinion and flywheel ring gear may clash resulting in damage to the starter.

Operation

If the starter does not turn the engine over, shut of f starter immediately . Do not make further attempts to start the engine until the condition is corrected. Do not jump start using another battery . See your Kohler Engine Service Dealer for service assistance

6. For a Cold Engine — Gradually return the choke control to the “off”

position after the engine starts and warms up.

The engine/equipment may be operated during the warm up period, but it may be necessary to leave the choke partially on until the engine warms up.

7. For a Warm Engine — Return

choke to “off” position as soon as engine starts.

STARTING INSTRUCTIONS: PTO MODELS

NOTE

This chipper is designed to be used with tractor PTO's rated at 15 to 45 horsepower. Using this chipper with PTO's above 45 horsepower may cause belt and machine damage in overload conditions.

1. Place tractor transmission in neutral and set parking brake.

2. Connect 3 pt. mounts between the

chipper and the tractor. Secure connections with snap pins. Adjust 3 pt. top link so that chipper sits level.

3. Connect PTO shaft to tractor. Make

sure you are using the correct RPM machine.

CHIPPING GUIDE

The Bear Cat chipper is designed to chip a variety of materials into a more readily decomposing or handled condition. The following guidelines can be used to help you get started.

• Run unit at full operating speed before starting to chip material.

• Select limbs that are up to 5 inches in diameter. Trim side branches that cannot be bent

Operation

enough to feed into the chipper chute. Hold small diameter branches together in a bundle and feed in simultaneously .

NOTE

Please read and follow all safety instructions in this manual. Failure to operate the chipper in accordance with the safety instructions MAY RESULT IN PERSONAL INJURY!

IMPORTANT

Exclude pieces of metal, rocks, bottles, cans, and other foreign objects when feeding chipable material into the machine.

• Feed brush from the side of the chipper chute, rather than from the front. Then, step aside to avoid being hit by the brush moving into the chipper.

• Do not lean over the chipper chute to push objects into the cutting device. Use a push stick or brush paddle.

• Never use shovels or forks to push brush. They can be chipped, are expensive to replace, and cause extensive damage. In addition, metal pieces can come back to injure or kill.

• Never push brush into the chipper chute with your feet.

• Place limb, butt end first, into the chipper chute until it contacts the chipper blades. The actual feed rate of the limb into the chipper will depend on the type of material fed and sharpness of the cutting blades.

• Stop the material feeding and allow the engine to recover if the engine slows to where it may stall.

• Remove the branch and rotate it before reinserting it into the chute if the chipper jams.

• Alternately insert and retract the limb or insert continuously at a rate that will not kill the engine.

• Chipping dead, dry material will create heat and dull the chipping blades quickly .

• Alternate greener material with dry material to lubricate the chipping blades for longer life and better performance.

• When the chipping blades become dull, they will require periodic sharpening. Refer to Service and Maintenance, "Sharpening Chipper Blades."

WARNING

Do not leave machine unattended, or attempt any inspection or service unless the engine is stopped and the key removed from key switch.

SHREDDING GUIDE

1. Place materials to be shredded (grass, leaves, garden refuse, sticks and branches less then 3/4 inch diameter and 24 inches long, etc.) into the hopper. Feed material evenly into the shredder so that the engine does not lug down or the shredder becomes plugged. Attempting to use the clutch to clear a plugged rotor will cause belt damage. Refer to Section 5, Clearing Plugged Rotor, for instructions. Branches or items that plug or cause the machine to stall should be fed in more evenly or put through the chipper chute.

SHARPENING CHIPPER BLADES

The chipper blades will eventually become dull, making chipping difficult. It is recommended that the chipper blades are sharpened every 5-15 hours of chipper operation. T o remove the chipping blades for sharpening, use the following procedure:

W ARNING

T o prevent personal injury or property damage: Shut of f engine, disconnect spark plug wire, remove ignition key , disconnect the PTO driveline from the source providing power or disconnect the driveline from the chipper shredder and make sure that all moving parts have come to a complete stop, before, servicing, adjusting or repairing.

The chipping blades are sharp! Use care when working on machine to avoid injury .

1. Loosen and remove the 3/8” carriage bolt securing the chipper top.

2. Open the chipper top cover exposing the chipper shredder compartment.

3. Rotate the rotor so that the bolts holding the chipper blade are most accessible.

NOTE

Never sharpen or grind on the back side of the chipper blade. This will cause the edge to roll and the chipping blade will be damaged, causing poor chipping and feeding of material. Small imperfections, nicks, burrs, etc. on the flat side of the blade will not affect performance of the machine.

Chipping Blade Sharpening Tips

Poor chipping performance is usually a result of dull chipping blades. If your chipper's performance has decreased, check for the following symptoms:

• Severe vibration when feeding material into the chipper.

• Small diameter branches do not self-feed.

• Chips discharge unevenly or have stringy tails–especially when chipping green branches.

Before you sharpen the chipping blades, check for permanent damage. Replace the blade if:

• The blade is cracked (especially around the bolt holes) or the edges are too deeply chipped to be ground smooth.

• The base of the cutting edge is worn or has been resharpened so that it is too close to the rotor chipping slot.

4. Remove the two hex head bolts holding the blade itself. Repeat for the second blade.

Grind the angled edge of the chipping blade to 45 degrees Grind the blades on a slow-speed wet grinder if possible, or have them sharpened by a professional. If you use a bench grinder, be careful when grinding so that the blade material does not get too hot and change color–this will remove the blade's special heat treated properties. Use short grinding times and cool with water. T ry to remove an equal amount off each blade to maintain balance. Replace the chipping blades and tighten bolts to 20 ft. lbs.

IMPORTANT

Do not exceed the recommended torque value of 20 ft. lbs. when tightening the bolts for the chipper blades.
