3.4 Filling Air Lubricator
The lubricator may be filled without shutting down equipment,
regardless of whether or not the system is under pressure. To fill
through the fill port, use a bottle with a long spout or a small funnel.
Slowly remove the lubricator fill plug and insert the tip of the bottle
spout or funnel to the bottom of the fill port recess, or oil back-out
will occur. Fill to 1⁄2" below the top of the bowl.
CAUTION: Maintaining the lubricator oil level is
critical to the life of the pump.
3.5 Air Lubricator Adjustment
The adjustment knob (C) is factory-adjusted so that when it is
turned fully clockwise, no oil is delivered to lubricate the system.
To make initial adjustment,
turn on the air and start flow
to the system. Turn knob to
adjust oil drip rate. Turning
knob counter-clockwise
increases drip rate. Set the
drip rate to one or two drops
per minute initially and fine
tune the rate after the
system reaches its normal
operating temperature.
To check lubrication, hold a
mirror near the equipment
exhaust. If a heavy film
develops, reduce
lubrication. Once the final
setting has been
determined, remove the knob to prevent tampering with the
adjustment setting.
IMPORTANT: If the lubricator is used in cycling applications, the
lubricator must stay pressurized during on and off cycles. Cycle
time must be at least 15 seconds, and the flow rate during each
cycle must be at least 4 SCFM.
WARNING: The lubricator has a polycarbonate
bowl. Synthetic base oils or oils containing
phosphate esters or chlorinated hydrocarbons will
attack polycarbonate bowls and can result in a rupture of
the bowl. Do not use an air compressor which uses these
oils. Do not expose the bowl to materials such as carbon
tetrachloride, trichlorethylene, acetone, paint thinner,
cleaning fluids, which will cause the plastic to craze or
rupture. Before using the lubricator, consult Enerpac for
further information if you are not sure if a substance in the
work environment will be harmful.

4.0 OPERATION
IMPORTANT: When possible, a single user should operate the
torque wrench and pump. This can prevent accidental activation
of the pump while the operator is positioning the wrench.

4.1 Air Removal

When the wrench is first connected
to the pump, air will be trapped in
the components. To ensure smooth and safe operation, remove
air by cycling wrench several times without load.
wrench advances and retracts without hesitation.
Check oil level before operation.

4.2 Gauge and Overlay Operating Procedure
The pump is supplied with a
pressure gauge installed. For your
convenience, torque overlays are
provided with each pump. A torque
overlay fits over the pressure
gauge dial face and easily converts
pressure
readings (see Fig. 5). The overlay
has imperial units (Ft-Lbs.) on one
side and metric units (Nm) on the
other. To change scales simply slip
overlay over.

Check all system fittings and connections to be sure they are
tight and leak free.
Check oil level in reservoir. Oil level should be one inch below
breather opening.
To start the pump, press the
green ADVANCE/ON button
(D) on the pendant. The tool
will advance as long as the
button is held down.
Release the button to retract
the wrench. The motor
remain on for 10-30 seconds.
Press the red OFF button (E)
on the pendant to stop the
pump motor. Oil from the
retract line will return to tank.

WARNING: Each overlay is sized for a specific
Enerpac torque wrench ONLY. Do not use with other
wrenches.
Remove the three black wing knobs which hold the front
gauge flange in place (see Fig. 6).
Remove the front flange and overlay (see Fig. 7).
