pump.
To Activate the Pump
Depress the
ADVANCE
end of the treadle as shown in
Figure 6, and the air motor will be activated to pump
hydraulic oil to the system.
To Hold Load Pressure
The air motor will stop and hold load pressure when the
treadle is in the free
NEUTRAL
position. See Figure 6.
To Release Load Pressure
To release load pressure or retract a cylinder, depress the
RELEASE
end of the treadle as shown in Figure 6.
PRIMING THE PUMP
If pump does not operate properly, it may have lost its prime. Follow the procedure
below to prime your pump, if necessary.
1. Fill pump with Enerpac hydraulic oil, if necessary. See filling instructions on page 2.
2. Place pump on horizontal surface.
3. Set air supply pressure to 30-40 psi [2,1 - 2,7 bar].
4. Move pump treadle to
RELEASE
position.
5. Depress the button under the treadle to activate pump. Operate pump in
RELEASE
position momentarily several times to allow oil to flow back into pump and fill
passage ways.
6. To verify that pump is primed, operate as normal with cylinder attached. If cylinder
does not advance, repeat step 5.
If pump still does not deliver oil, contact your Authorized Enerpac Service Center.
