OPERATION
CUTOFF WHEEL REPLACEMENT
1.Move the hydraulic system control valve to the Off posi- tion.
2.Disconnect the hydraulic hoses from the tool (first the input (supply) hose, then the output (return) hose).
3.Install the inside collar and blotter, rotate the collar to align the slot in the collar with the pin on the thrust collar.
4.The maximum rated speed of the hydraulic cutoff saw is 4500 rpm. Never install a cutoff wheel that is not rated equal to or greater than that of the tool to ensure the integ- rity of the wheel at the maximum tool speed.
5.Prior to installing the wheel, inspect it for chips, cracks or other damage and replace if damaged.
6.Install the outside blotter and collar, rotate the collar so that the flat on the motor shaft aligns with the flat on the outside collar.
7.Install the wheel nut using a wrench while gripping the cutoff wheel. Tighten securely.
COLD WEATHER OPERATION
Before using the tool in cold weather, preheat the hydraulic
fluid with the power unit operating at a low speed. The oil
should be at or above 50°F (10°C) with a viscosity of 400 SSU (82 cs) before operating the tool.
