4.3 Air Supply Connections
Pump requires 60-100 psi dynamic air pressure at 20-100 cfm.
Attach incoming air supply to the 1/2" NPT port on the regulator/
fi lter/lubricator.
4.4 Fluid Level
Check the oil level of the pump prior to start-up, if necessary add
oil by removing the SAE #10 plug from the cover plate (see Fig. 2).
The reservoir is full when the oil level reaches the top of the sight
glass. (Fig. 4).
4 and 8 liter
Tank is full
when oil level
is here.
Figure 4
IMPORTANT: Add oil only when all system components are fully
retracted, or the system will contain more oil than the reservoir
can hold.
4.5 Connect Hydraulic Hoses
Connect hoses as shown in Figure 5.
1. (-E) Pump type for Enerpac SQD and HXD torque wrenches.
Be sure to use hoses marked “ENERPAC THC-700 SERIES
- 800 Bar/11,600 psi max.” The couplers on these hoses are
“polarized” at the factory to ensure correct wrench operation.
(See fi gure 5.)
A. Hose and wrench female couplers. Hand tighten threaded
coupler lock rings, no tools are required.
B. The (-E) pump’s female couplers are self locking, press
mating couplers together until coupler lock ring snaps
forward. To disconnect, twist coupler lock ring clockwise and
push away from connection.
2. (-Q) Pump type for Enerpac S and W torque wrenches
and other brands. Use hoses marked "Enerpac THQ-700
series-700 bar/10,000 psi max.". Couplers must be polarized
per fi gure 5 for correct wrench operation. Ensure couplers are
fully engaged and tightened before operating. Partial coupler
engagement will prevent proper wrench operation.
4.6 Filling Air Lubricator
Fill lubricator reservoir with a light misting type oil suitable for
compressed air tools.
CAUTION: Maintaining the lubricator oil level is critical
to the life of the pump.
4.7 Air Lubricator Adjustment
The adjustment screw (E) is factory-adjusted fully clockwise, so no oil
is delivered to lubricate the system. To make initial adjustment, turn
on the air and start fl ow to the system. Turn knob to adjust oil drip
rate. Turning knob counter-clockwise increases drip rate. (see Fig. 6)
Set the drip rate to one or two drops per minute initially and fi ne tune
the rate after the system reaches its normal operating temperature.
To check lubrication, hold a mirror near the equipment exhaust. If
a heavy fi lm develops, reduce lubrication.
4.8 Air Pressure Regulator Adjustment
Pull knob straight up to unlock. The
adjustment knob must be turned clockwise
to increase and counter-clockwise to
decrease outlet pressure setting. To reduce
pressure, fi rst reduce to a pressure less than
that desired, then increase to the desired
outlet pressure.
(See fi gure 6.)
