HOSES AND FITTINGS There exists the potential for shock in using anything other than certified nonconductive hoses and hydraulic oil with dielectric properties, when using system components near WARNING energized electrical lines. Failure to recognize these conditions could cause electrocution. Hoses and fittings used with this tool must comply with S.A.E.
Page 9: Operation Of Saw
PRE-OPERATION OF SAW WARNING! DO NOT connect hoses or fittings to this chainsaw before completing all the following instructions. Before attempting to run or use the saw, check all connections, including hoses, couplings, chain tension, cleanliness of the fiberglass extension, trigger latch, freely moving trigger, and the condition of the rubber behind the trigger.
Page 10: Safety Instructions
OPERATION Hold the fiberglass tube extension in one hand and the handle in the other hand. After positioning the saw in the cutting area, move the trigger safety latch to a forward position, allowing the trigger to be depressed. Depress the trigger slowly and allow the chain to start rotating.
Page 11 MAINTENANCE The service schedule should be followed as closely as possible. The life, reliability, and safety of the tool is dependent on maintenance and will help the tool to remain productive for a much longer period. DAILY MAINTENANCE CLEAN: All surfaces including handle, trigger, trigger safety latch, fittings, hoses, motor housing, and especially the fiberglass extension tube.
Page 12 SERVICE Automatic Chain Oiler: The automatic chain oiler is designed to continuously lubricate the chain and the guide bar while the chainsaw is running. This lubrication is an important factor in minimizing wear and tear on components as is commonly found in chainsaws. By utilizing the fluid from the supply circuit and sending the fluid through a metering valve, the fluid is then directed to the chain and guide in the quantity required.
Page 13 Saw Chain Tension: Tension checking and adjusting must be done frequently before start and during cutting operations. The chain must be set to the proper tension in order for the saw to function properly. If the chain is too loose, the chain can jump the track of the guide bar, probably causing damage to the bar and associated components.
