OPERATION
Switch Operation (Figure 6)
Pump Control Valve
NOTE: To avoid power losses between the electrical outlet and pump motor, use the
shortest possible extension cord. The pump motor will function at low voltage, but
motor speed and oil flow will be reduced.
1. Check all system fittings and connections to be sure they are tight and leak free.
2. Check the fluid level and add fluid, if necessary.
3. Open the pump vent plug (F) located on the front right corner of the reservoir by turning it 1 or
2 complete turns.
CAUTION
The vent plug must be open whenever the pump is running.
The "B" version requires a 15 amp, 120 V. grounded 1 Ph. circuit. The "E" version requires 220
V. 1 Ph. The pump power cord is 5 ft. (1
1. The pump switch is located on the side of the shroud. It is a three position switch, top detent is
"ON", middle is "OFF", bottom is momentary on "MOM". Pressing the top "ON" position
activates the electrical circuit, but does not turn the pump motor on. The pump motor is
activated by the pendant switch (G).
2. Pressing the lower portion of the switch will activate the pump motor as long as the switch is
held down. Releasing the switch stops the pump. This momentary position is used as an
alternate to the pendant control.
PUJ-1200B/E and PUJ-1201B/E models
The pump control valve directs hydraulic fluid output or return from the hydraulic system
components. These models have 3 way, 2 position valves.
Valve positions are shown in Figure 7: 1 - Advance
To advance the cylinder, shift the valve to the advance position (1) and press the pendant switch.
The cylinder will advance until the pendant switch is released.
To retract the cylinder, shift the valve to the retract position (3). The cylinder will retract with or
without the pump running.
