4.0 PUMP SET-UP
4.1 Oil Reservoir
Check pump oil level prior to start-up. Before checking oil level:
• Be sure that air-shutoff valve is CLOSED and that oil return-to-
tank valve is OPEN. See Figure 1.
• Be sure that the pump hydraulic pressure and air pressure
gauges both indicate zero [0] psi/bar.
The reservoir is FULL when oil level is at the top of the reservoir
as shown in Figure 3. Oil capacity is approximately 1 US gallon
[3,8 liters]. Use Enerpac Type HF Oil.
IMPORTANT: Add oil only when all system components are fully
retracted, or the system will contain more oil than the reservoir
can hold.

4.2 Air and Hydraulic Connections
WARNING: Before connecting air supply, ensure that
the air-shutoff (on-off) valve is closed (i.e. handle in
vertical position) and that the oil return-to-tank valve is
open. See Figure 1. Also, be sure that the air pressure regulator
is fully turned off, so that pump air pressure gauge indicates zero
[0] psi.
Make connections as required:
• The pump air inlet is located on the air pressure regulator
assembly. It is a standard 1/2" NPT connection.
• The pump hydraulic oil outlet is a 1/4" female BSPP connection.
On pumps used in bolting applications, a female quick-disconnect
coupler is typically installed in the BSPP connection.
4.3 Air Requirements
Pump air consumption is approximately 21 SCFM [113 l/min] of
free air at 100 psi [6,8 bar] oil discharge pressure. At lower air
pressures and higher hydraulic pressures, air consumption will
be reduced proportionally to the flow rates indicated.
IMPORTANT: Pump air supply pressure should not exceed 90
psi [6,2 bar] static.
WARNING: The pump air pressure relief valve is factory
set at approximately 90 psi [6,2 bar]. To prevent personal
injury and equipment damage, do not attempt to raise
relief valve setting.
Use only dry and filtered compressed air. Use of a water separator
is strongly recommended.
Pump internal components are self-lubricating. Lubricated air is
NOT required.
