If you did not receive a battery with your machine, you will need to purchase one. 6. After filling, battery should be charged to the specifications below and put into service immediately. Temperature over 60° F: 3 amperes for 4 Hours. Temperature under 60° F: 3 amperes for 6 Hours. 2. Use a battery that meets or exceeds the following specifications: 7.
3 Controls Section 3.1 TOWABLE MODELS 5. Jack Stand. Always have up and clear from the ground when moving the unit. When the in use, be sure jack stand is down and locked in position with the snap pin. 1. Engine: (See Fig. # 6) Refer to Honda Engine Operators Manual. 6. Foot Pedal: Used to engage rotor drive belt. Pressing the pedal releases tension on the drive belt. 2. Engine Fuel Tank. Use unleaded fuel only. DO NOT MIX OIL AND GASOLINE. 6.
Controls 3.2 PTO MODELS 1. 3 pt. Hitch Connections: Mount chipper/shredder to tractor (Fig. # 7). Connect direct for categories 0 & 1. A bushing kit must be installed on 3 pt. connections for category 2 hitches. 2. PTO Shaft: Connects tractor PTO to chipper/ shredder drive shaft. Avoid angle greater than 15 degrees up or down when unit is in use. 3. Leg Stands: Adjustable to allow proper driveshaft angle. Do not move machine unless the legs clear the ground. 4.
4 Operation Section 4.0 OPERATION 4.2 STARTING (PTO MODELS) 4.1 STARTING (TOWABLE MODEL) 1. Place tractor transmission in neutral and set parking brake. Move machine to a clear, level area outdoors before starting. Do not operate machine on a paved, concrete, or gravel surface. Do not operate in the vicinity of bystanders. Make sure cutting chamber is empty before starting. 1. Before starting, check engine oil level and fill if necessary.
Operation 4.4 HYDRAULIC FEED INSTRUCTIONS 3. Fill the inlet line leading from the reservoir to the hydraulic pump before start-up. Loosen the fitting on the pump inlet line until oil bleeds out. 4. Start the engine and run at the lowest possible RPM. 4.4.1 FLUIDS Handle pressurized hydraulic fluid carefully. Escaping pressurized hydraulic fluid can have sufficient force to penetrate your skin causing serious injury. This fluid may also be hot enough to burn.
Operation 4.4.3 CONTROL ARM OPERATION l. Start the chipper engine or engage the PTO. Bring the chipper up to operating speed. Refer to and follow the engine starting, chipper operation, and engine stopping instructions. 2. Engage the hydraulic feed by moving the control arm. The control arm has four positions: Reverse, Forward, Stop, and Reverse. 3. Feed the branch (up to five inches in diameter). 4. Reverse the feed by moving the control arm to either reverse position if the chipper jams.
Operation 4.5 FEED SENSOR INSTRUCTIONS B. ENTER LOW (L=LOW) RPM The feed sensor monitors the chipper rotor RPM to maximize chipping efficiency. The low RPM setting is the rotor speed when the feed roller stops. The feed sensor restarts the feed roller when the chipper rotor RPM reaches the return operating speed. This ability to automatically stop the feed roller prevents the engine from overloading and stalling. The low setting is the RPM speed where the feed roller stops.
Operation 4.6 CHIPPING TIPS 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. 1. Run unit at full operating speed before starting to chip material. 2. Select limbs that are up to 5 inches in diameter. Trim side branches that cannot be bent enough to feed into the chipper chute. Hold small diameter branches together in a bundle and fed in simultaneously. 3.
5 Service & Maintenance Section WARNING Before inspecting or repairing any part of the machine, shut off the engine and make sure all moving parts have come to a complete stop. 5.0 SERVICE AND MAINTENANCE 5.
Service and Maintenance 5.2 SHARPENING CHIPPER BLADES WARNING 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. The chipping blades are sharp! Use care when working on machine to avoid injury. The chipper blades will eventually dull, making chipping difficult. It is recommended to sharpen chipper blades every 5-15 hours of chipper operation. 5.
Service and Maintenance 5.4 SETTING CHIPPING BLADE CLEARANCE 5.5 CLEANING PLUGGED ROTOR The chipping blades should clear the chipper block located directly under the chipper chute by 1/16 inch to 1/8 inch. To adjust the blade clearance, proceed as follows: Feeding too much chipable material at once can plug the chipper. To clear plugged rotor, proceed as follows: 1. Lift rotor access cover and expose rotor. Loosen the two 1/2 inch bolts that hold the chipper anvil to the frame. 2.
Service and Maintenance 5.6 REPLACING DRIVE BELTS (TOWABLE MODELS) 5.7 REPLACING DRIVE BELTS (PTO MODELS) Check the condition of the drive belt annually or after every 25 hours of operation, whichever comes first. Replace cracked, frayed, worn, or stretched drive belt. Only replace drive belt with original banded type belt, do not use single type belts. To adjust the drive belt, proceed as follows: 1. Remove large belt guard (three 5/16" bolts). 2. Loosen eye bolt. 3.
Service and Maintenance 5.8 REMOVING ROTOR 5.9 TRAILER SERVICE TIPS 1. Remove the one 3/8 inch retaining bolt holding access cover to main frame assembly. Tilt access cover over to allow rotor access. 1. Check wheel bolt torque every 10 hours of towing use. 2. Check air pressure in tires every 10 hours of towing. 2. Remove large belt guard (three or five 5/16 inch bolts). 3. Check and repack wheel bearings with grease every 12 months. 3.
