Remove shipping screw located on the top side of the cover. Replace shipping screw with the
supplied oil dipstick. Do not use a wrench or over tighten when installing the dipstick. Please
keep the shipping screw if needed for shipping or transport.
The pump is filled with high quality hydraulic oil at the factory. Prior to operation check that the
hydraulic fluid level is at the correct fluid level. If you need to add fluid unscrew the dipstick and
use a small funnel to fill. Use only high quality hydraulic fluid. Use of any other fluid will void
warranty and damage the pump. Never use brake fluid, transmisstion fluid, motor oil etc.

OPERATION
!
Hydraulic Connection
• Remove the plastic cap FIG 1. Please keep this cap for shipping or storage.
• Connect NPT 3/8" hydraulic line to the output port.
• If needed the unit comes with an adaptor to attach a 1/4" NPT hydraulic line FIG 2.
FIG 1 FIG 2
Air Connection
• Remove plastic cap FIG 3, Please keep this cap for shipping or storage.
• Connect your 1/4" NPT air nipple (not included) to the air input port FIG 4.
• Tighten the air nipple but do not overtighten.
FIG 3 FIG 4
• Connect air source to the hose conector.
• Ensure that air source can dedicate 9 cfm air supply. Use a good quality 3/8" air line hose.
Always secure threaded port connections with high grade, pipe thread sealant.
• When using the pump always use on a flat level surface. If the pump needs to be fixed to
a level service, unit comes with 4 self tapping screw holes. Maximum screw length into the
pump is 10-13 mm.

OPERATION
!
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.
FIG. 5 FIG. 6
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.
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.

MAINTENANCE AND STORAGE
!
Add several drops of lubrication to the air-inlet port periodically to lubricate the air motor.
When the unit will be stored for a long time without using, please follow the instructions below:
• Wipe the entire unit clean.
• Disconnect all air pressure and hydraulic lines to prevent accidental operation.
• Remove the oil dipstick and replace with the plug.
• Take off the air hose connector and replace it with the plug.
• Take off the 3/8" oil hose or adaptor with the NPT 1/4" oil hose and replace it with the plug.
• Put the pump into the package and store it in a clean, dry environment.
• DO NOT expose equipment to extreme temperatures.
