Hydraulic Pressure Test
To check hydraulic pressure:
See Figure 6-2.
Operate the loading arm hydraulic lever and read the pressure on the gauge. Hydraulic
pressure is factory-set at 2200 psi (15,17 MPa) 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 2200 psi
(15,17 MPa). If it does, the amp draw will rise above the
design maximum of 200 amps, and could cause battery and
system problems. Pressure above 2200 psi (15,17 MPa)
may also damage the hydraulic hoses.
