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

OURS

M-F, 8 a.m. to 5

p.m. Central Time

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 Bear Cat engines 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.

SERIAL NUMBER LOCATION

Always give your authorized Bear Cat dealer the serial number of your Crary Bear Cat Chipper Shredder when ordering parts, requesting service or any other information. The serial number decal for Model # 70050(S) is located at the rear of the machine (See Fig. # 2). The serial number decal for Model # 70080(S), 70085, 70180(S), 70380(S) & 70385 is located at the rear of the machine (See Fig. # 3). The serial number decal for Model # 70580(S) is located at the left, rear of the machine (See Fig. # 4). Please record the serial number in the space provided below and on the warranty and registration card.

Chipper Limited Warranty

Crary Bear Cat Chipper Shredders are warranted for two years from date of sale for consumers and 90 days from the date of sale for commercial or rental operations.

Within the above stated period, Crary Co. will replace any part(s) found to be defective in material and/or workmanship, after the receipt of the part in our plant. Labor costs to replace these defective parts will be paid at a Crary established labor rate and time allowed (flat rate) for repair. All transportation charges incurred in shipping part(s) are the responsibility of the purchaser.

This warranty is void in the case of accidents, failure to perform normal maintenance, or failure to follow those instructions listed in the service manual. This warranty is also in lieu of all other expressed warranties and voids any implied warranty as to the merchantability or fitness of the product for a particular purpose and of any other obligation on the part of Crary Co. Some states do not allow limitations on how long the implied warranty lasts, so the above limitation may not apply to you.

This warranty applies only to parts or components which are defective, and does not cover necessary repair due to normal wear, misuse, accidents, or lack of proper maintenance.

Regular routine maintenance of the unit to keep it in proper operating condition is the responsibility of the owner.

All warranty repair reimbursable under the Crary Co. warranty must be performed by an authorized Bear Cat service dealer using Bear Cat approved replacement parts. Repair or attempted repair by anyone other than an authorized Bear Cat service dealer, or repairs using parts not approved by Bear Cat are not reimbursable under the Crary Co. warranty. In addition, these unauthorized repair attempts may result in additional malfunction, the correction of which is not covered by warranty.

Crary Co. is not liable for indirect, incidental, or consequential damages in connection with the use of this product including any cost or expense or providing substitute equipment or service during periods of malfunction or non-use.

Some states do not allow the exclusion of incidental or consequential damages, so the above exclusion may not apply to you. This warranty gives you specific legal rights. You may also have other rights which vary from state to state.

Operation

Section

WARNING

Before operating your machine, be sure you read and understand all safety, controls and operating instructions in this Owner/Operators manual and on your machine.

Read this section thoroughly before you start the engine. The instructions given here will help you become familiar with your machine and have you operating efficiently in a short time.

This Section explains how to:

• Fill the tank

• Start Electric models

Failure to follow these instructions can result in serious injury or property damage.

As with any other piece of outdoor power equipment, getting the “feel” for how your machine operates and getting to know the best techniques for particular jobs are important to overall good performance.

FILLING THE TANK

DANGER

Gasoline is highly flammable and its vapors are explosive. To 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.

• Start recoil models

• Stop the machine

• Chip

• Shred

• Change the discharge screen

• Clear the machine of a plugged rotor

FILLING THE FUEL TANK

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 Briggs and Honda 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 Briggs and Honda engines. Other gasoline/ether blends are not approved.

To Add Gasoline.

1. Stop engine, wait for all parts to stop moving, and disconnect spark plug wire. Remove Key/Tool 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” below bottom of filler neck to provide space for any fuel expansion. Install fuel fill cap securely and wipe up any spilled gasoline.

STARTING ELECTRIC MODELS

Operation

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

4. Move throttle to full position.

5. Slowly engage the hand lever to start 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

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, damage to the starter may result.

NOTE

If the starter does not turn the engine over, shut off starter immediately. Do not make further attempts to start the engine until the condition is corrected. Do not jump start using another battery.

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 RECOIL 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. Turn the key switch to “on” (if equipped). Pull the recoil starter until the engine starts. Make sure the starting cord retracts.

4. Move throttle to full position.

5. Slowly engage the hand lever to start the chipper shredder.

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

STOPPING THE CHIPPER/SHREDDER

1. Move the throttle to the “slow” or “low” idle position.

WARNING

Allow the machine to come to complete stop before inspection or servicing. The rotor is

heavy and has inertia built up that will allow the rotor continue to turn for some time after the clutch has been disengaged. You can distinguish when the rotor has come to a complete stop when there is no noise, vibration, or by reengaging the clutch to slow the rotor to a stop.

2. Disengage the clutch engagement arm.

3. Allow the engine to run at idle for 30-60 seconds; then stop the

4. Allow machine to come to a complete stop.

SHARPENING CHIPPER BLADES

The chipper blades will eventually become dull, making chipping difficult and adding extra strain on the machine. Sharpen

the chipper blades every 5-15 hours of chipper operation. To remove the chipping blades for sharpening, follow

the procedure below:

Removing The Blades:

WARNING

To prevent personal injury or property damage: Shut off engine, disconnect spark plug wire, remove ignition key (if applicable), disconnect the driveline from the source providing power 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.

Service & Maintenance

2. Be sure to use short grinding times and cool with water between grinding.

3. Try to remove an equal amount off each blade to maintain balance.

NOTE

Never sharpen or grind on the back side of the chipper blade. This will cause the edge to roll and damage will occur to the chipping blade, 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.

4. The maximum that can be ground off the blades is .30

inches, after this the blades must be replaced. For refer ence, new blades are 2”.

Reinstalling the blades:

1. Place a blade back on the rotor and attach with 5/16” bolt. Repeat for the second blade.

1. Flip the discharge cover up.

2. Remove the 5/16” bolt and nylock nut holding the shredder screen.

3. Disconnect and remove the shredder screen from the machine.

4. Remove the two 5/16” hex head bolts holding the chipper blade itself. Repeat for the second blade.

5. Inspect blades to see if cracks or nicks are visible. If

cracks are present, replace the blades. If nicks can not be removed by sharpening blade, replace the blade.

Sharpening the Blades:

1. When sharpening the blades grind the angled edge of the chipping blade to 45 degrees. This is best accomplished on a slow-speed wet grinder. 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.

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

2. Reinstall the shredder screen on the unit.

3. Attach the shredder screen to the machine with the 5/16” bolt and nylock nut.

4. Place the discharge cover in the normal operating position.

Tips

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

1. Severe vibration when feeding material into the chipper.

2. Small diameter branches do not self-feed.

3. 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:

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

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

Service & Maintenance

SETTING CHIPPING BLADE CLEARANCE

WARNING

To prevent personal injury or property damage: Shut off engine, disconnect spark plug wire, remove ignition key (if applicable), 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.

The chipping blades should clear the chipper block located directly opposite the chipper chute intake by 1/16 inch to 1/ 8 inch. To adjust the blade clearance, proceed as follows:

1. Loosen the set screws holding the lock collars on the 2-bolt flange bearings.

2. Use a punch and hammer to tap the lock collars directly opposite of normal rotation.On the front side

tap punch in a CW rotation. On the rear side tap punch in a CCW rotation

mer, rotate the lock collars in the direction of shaft rotation (i.e. counterclockwise on the rear bearing and clockwise on the front bearing) and "set" them with a positive hammer tap. Tighten the lock collar set screws.

5. Loosen the set screws holding the belt pulley on the rotor shaft. Move the pulley on the shaft so it is aligned with the engine drive pulley. The pulley should be moved the same amount the rotor was moved, only in the opposite direction.

6. Insure the pulley drive key is completely seated under the pulley and tighten the set screws.

7. Check pulley alignment by laying a straightedge across the pulley faces. Pulley faces should line up. If not, repeat steps 9 and 10 until the pulley is lined up.

3. Using a rubber mallet tap the end of the rotor shaft to obtain 1/16” to 1/8” of an inch clearance. Rotate the rotor and check the clearance on all chipping blades.

4. Once clearance has been set, the lock collars must be replaced and retightened. Using a punch and a ham-

GREASING

Service & Maintenance

Use an SAE multi-purpose high temperature grease with extreme pressure (EP) performance meeting or exceeding the NLGI # 2 rating for all requirements. Also acceptable is an SAE multi-purpose lithium based grease.

Care should be taken when re-greasing bearings to not overfill the bearing. Over greasing can lead to overheating and/ or unsealing the bearing seals.

WARNING

To prevent personal injury or property damage: Shut off engine, disconnect spark plug wire and make sure that all moving parts have come to a complete stop before, servicing, adjusting or repairing.

1. Use a hand-held grease gun for all greasing.

2. Wipe grease fitting with a clean cloth before greasing, to avoid injecting dirt and grit.

3. Replace and repair broken fittings immediately.

4. If fittings will not take grease, remove and clean thoroughly. Also clean lubricant passageway. Replace fitting if necessary.
