On new pumps, remove the reservoir shipping plug (A) and install
strainer washer (B) and filler cap (C). See Figure 3.

4.2 Adding Oil

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.
• Be sure that the reservoir outlet valve is in the open position.
See Figure 4.
The reservoir is FULL when the oil level in the upper sight glass
is about halfway up, as shown in Figure 4. 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.

4.3 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/bar.
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.
