PUD1301B/E Models
1. The pump-to-cylinder hose attaches directly to the output
port (A) of the control valve (see Figure 4).
2. If a gauge is desired to monitor system pressure, a gauge
adaptor must be installed into the valve outlet port (A). Install
a 0-10,000 psi (700 Bar) pressure gauge into the gauge port
of the gauge adaptor.

4.2 Valve Mounting (Figure 5)
1. Remove the plate (No. 1, D43918098).
2. Verify that the connector (2) is installed in the pump. If it is
not, install the connector, taking care to avoid shearing the
seals.

3. Mount the valve (3), taking care to avoid shearing the seals.
4.3 Adding Oil (Figure 6)
Check the oil level by unscrewing and removing the vent/fill plug
(F). Add Enerpac hydraulic oil until the oil level is 1/2 inch (1 cm)
below the vent/fill opening.
IMPORTANT: Add oil only when all system components are fully
retracted, or the system will contain more oil than the reservoir
can hold.

5.0 OPERATION
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.
5.1 Switch Operation (Figure 7)
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 1/2 meters) long.
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.
