AIR REMOVAL
Removing air from the hydraulic system will help the cylinder to advance and retract smoothly.
Pump with Single-Acting Cylinder
• Position pump at higher elevation than cylinder.
• Position cylinder with plunger end down (up if using pull cylinder)
• Operate pump to fully extend the cylinder (retract if using pull cylinder)
• Depress release valve to retract cylinder (extend if a pull cylinder). This will force the trapped
air to move up to the pump reservoir.
• Repeat the above steps as necessary.
• Add oil if necessary.
• Return vent/ll cap to operating position.
How to ll the reservoir
1. Disconnect hydraulic coupler from application, remove air supply from pump.
2. Remove the vent /oil ller plug.
3. Fill reservoir to within ½ inch of the opening.
4. Wipe off any spilled uid and install oil ller plug.
NOTE:
Use only quality hydraulic fluid. Never use brake fluid, transmission fluid, motor oil
etc. Use of other than quality hydraulic oil will void the warranty and damage the
equipment.
AIR SUPPLY
• To obtain maximum performance and rated hydraulic pressure, air pressure should be 100 psi
minimum.
• To insure trouble-free performance, your air supply equipment should be equipped with an air
lter/dryer and the compressor tank should be drained of water everyday.
LUBRICATION
• To insure long service life, add a few drops of # 30 oil into the air inlet once a week.
MAINTENANCE
Use only recommended JACKCO hydraulic oil with theses pumps to promote long pump life and
protect your warranty. Contact your JACKCO representative for more information on these products
and their applications.
KEEPING OIL LINES CLEAN
When coupler halves are disconnected, always screw on dust caps. Use every precaution to guard
unit against entrance of dirt because foreign matter may cause pump, cylinder or valve failure.
CHANGING THE OIL
• Drain all oil and rell with clean JACKCO hydraulic oil every 12 months, if pump is used in dirty
environments, change the oil more often.
• Remove vent/ll cap or plug from reservoir
• Tilt pump to drain out old oil.
