OPERATION
NOTE: Preform the following
Once the direction of rotation has been determined to be correct and the Control Valve notation indicates the correct direction (in the case of dual direction installations), return the Grizzly to the horizontal position a foot or so above the ground and run it up to speed. It will probably be necessary to increase the engine speed to provide adequate hydraulic pressure/volume to reach maximum shaft speed.
WARNING! DO NOT EXCEED 1800 RPM. The shaft speed of the Grizzly must not - UNDER ANY CIRCUMSTANCES- exceed 1800 RPM. Operation in excess of the maximum RPM may result in damage to component parts and is a safety hazard.
Once it is verified that everything is working satisfactorily, shut the machine down and review the Daily Check List before proceeding.
Normal Operation
CAUTION! First, inspect the area to be cut. Walk through the area looking for rocks, boulders, culverts, stumps, etc. Mark the area with flags. (See Safety Section for instruction on Work Area Preparation).
Drive the tractor to the start of the inspected area, lower the cutter head close to the material to be cleared and engage the cutter. ALWAYS engage the cutter with the tractor engine at IDLE to avoid damage to the coupling.
Increase the engine speed to bring the cutter speed up to operational level. DO NOT EXCEED1800 RPM shaft speed. Lower the cutter to the material.
The "GATE" on the cutter shroud is normally on the "front" side of the shroud so the cutting swath is customarily outwards from the tractor.
Starting close to the tractor, cut or clear the material by sweeping the cutter outwards, then returning over the cleared area to start the next swath. Keep the cutting head parallel to the ground as far as possible to keep the debris from spraying outwards. Stop immediately and shut off the engine if the cutter hits a solid object, or vibrates excessively, and inspect for damage.
!!!!!!CEASE OPERATION IMMEDIATELY IF ANY PERSON OR ANIMAL ENTERS THE WORKING AREA!!!!!
DANGER! DO NOT OPERATE THE GRIZZLY WITHIN 10 FEET OF OVERHEAD POWER LINES!
WARNING! The operator's cab must be protected with a strong wire screen. Avoid cutting with the head tilted at such an angle that objects could be thrown towards the cab.
WARNING! Only engage the cutting head with the engine at IDLE. Provide a locking device to prevent accidental engagement when the operator is out of the cab.
