Depress the PUMP end of the treadle as shown in FIG. 5, the air motor will be activated to
pump hydraulic oil to the system.
Note:
If the pump doesn't work properly at first, it may have air in the hydraulic system.
If this happens you will need to prime the hydraulic system.
The air motor will stop and hold load pressure when the treadle is in the free NEUTRAL position.
To release load pressure or retract a cylinder, depress the RELEASE end of the treadle as
shown in FIG. 6, the release system will hold automatically. If you want fast release, depress the
RELEASE end until the pedal is clasped. If you want slow release, use only light foot pressure to
depress the RELEASE end and not to reach the clasped position.

Priming the Pump
If the pump doesn't work properly at first it may have air in the hydraulic system, if this happens
you will need to bleed the system.
1. Place pump on flat surface and depress the treadle RELEASE to clasp position in order to
ensure the oil back to reservoir.
2. Check the oil level. Fill the pump with high quality hydraulic oil, if necessary.
See filling instructions.
3. Move pump treadle to RELEASE position until the pedal is clasped tightly, then use a
screwdriver to depress the button under the treadle to activate pump. This will bleed the air
out of the system.
OPERATION
!
To verify that pump is primed, operate as normal with cylinder attached.
If cylinder does not advance, repeat the steps again. If pump still does not deliver oil,
please check the trouble shooting guide or contact your supplier for help.
