Troubleshooting Guide
3.
Restore power to the pump by moving the saw head back until it contacts the power strip.
4.
Operate the loading arm hydraulic lever and read the pressure on the gauge. Hydraulic
pressure is factory-set at 2000 ±100 psi and should not need to be readjusted. The relief
valve adjustment screw shown may be used to fine-tune the hydraulic pressure:
Remove the adjustment screw nut. Tighten the adjustment screw (clockwise) to increase
pressure. Loosen the adjustment screw (counterclockwise) to lower pressure.
CAUTION!
Pressure should not exceed 2000 psi. If it does,
the amp draw will rise above the design maximum of 200
amps, and could cause battery and system problems. Pres-
sure above 2000 psi may also damage the hydraulic hoses.
