Fill Hydraulic Reservoir
The unit is shipped without hydraulic fluid.
Refer to Figure 2-12:
1. Make sure all four park stands are properly pinned at
the same height and properly support the tank on a
hard level surface. Make sure bottom drain plug (#1)
is screwed in tight and ball valve lever (#3) is turned
off (90
o
to the valve).
2. Remove fill cap (#7) and add 35 gallons of Mobil 424
with viscosity rating of 10W-30 to the empty hydraulic
reservoir. Use care to ensure that dust or other
foreign particles do not contaminate the fluid.
3. Remove filler cap with dipstick (#3) from reservoir
and wipe clean. Fully insert filler cap with dipstick and
remove. Check oil level on dipstick.
4. Fill with recommended oil to full mark if low.
Replace filler cap and dipstick.

Ball valve (#3) must be open as
shown during pump operation or damage will occur.
Control Box Hook-up
Figure 2-13
Control Box Hook-up
Refer to Figure 2-13:
If Hydraulic Reservoir System is equipped with a
solenoid valve or oil cooler, then an electrical control box
with wiring harness is included. Make sure the control
box wiring is connected to a 12 volt electrical system.
The center red toggle switch turns power to the unit on
when pushed and off when pulled to neutral position. A
red lamp below the switch illuminates when switch is on.
The blue toggle switch is for continuous operation such
as a hydraulic motor. Push on the toggle switch to run a
hydraulic motor in one direction and pull to run the motor
in the opposite direction. Return switch to center position
to stop motor operation. A red lamp below the switch
illuminates while toggle switch is on.
The yellow toggle switch on the control box is for
momentary operation such as a hydraulic cylinder. Push
and hold the toggle switch to move the cylinder rod.
Release the toggle switch to stop movement. Push and
hold toggle switch in the other direction to reverse
cylinder rod movement.
The oil cooler is equipped with an oil temperature
sensing switch that turns on the fan when oil
temperatures reach 140
o
F.
Two of the weather proof terminals on the wiring harness
are for connecting to the solenoid and the other weather
proof terminal is for connecting to the oil cooler.
1. Locate and mount control box in a convenient
location for the operator.
2. Route wiring harness with ring terminals to a 12 volt
battery. Secure wiring harness with ties. Make sure
harness will not become pinched along the route.
a. Connect red terminal ring to the 12 volt positive
post (+) on the battery.
b. Connect black terminal ring to ground.
