OPERATION
Note: Inspect before each use for evidence of fluid leaks, damaged
hydraulic fittings, bent or broken attachments and missing parts.
1. Locate and close release valve by turning it clockwise until firmly
closed. (Do not over tighten)
2. Operate by pumping handle. This will send fluid from the pump
reservoir into the high pressure hose assembly and into the ram
assembly.
3. Continue pumping until ram reaches desired height.
Note: Pump may be used in horizontal and vertical position as
illustrated (See figure 2).
To Release Pressure on work piece:
Slowly, carefully turn the release valve counterclockwise until ram
retracts to desired position. Never turn release valve more than
1/2 full turn. The ram return system is spring loaded, allowing
controlled retraction of the ram.

MAINTENANCE
Important: Use only good grade hydraulic oil. We recommend Hein-Werner HW93291. Avoid mixing different types of
fluid and Never use brake fluid, turbine oil, transmission fluid, motor oil or glycerin. Improper fluid can cause failure of
the pump and the potential for sudden and immediate loss of load.
Adding oil
1. With ram fully lowered, set pump unit in its normal, level position. Locate and remove oil filler screw (see Figure 1).
2. Fill until oil is within 1/4" (6 mm) of the hole opening, reinstall oil filler screw.
Changing oil
For best performance and increased system life, replace the complete fluid supply at least once per year.
1. With ram fully lowered, remove the oil filler screw from the pump reservoir as above.
2. Lay the pump on its side and drain the fluid into a suitable container.
Note: Dispose of hydraulic fluid in accordance with local regulations.
3. Set pump in its level upright position.
4. Fill with good quality hydraulic oil to within 3/8" of the oil filler screw hole opening. Reinstall oil filler screw.
Lubrication
A periodic coating of light lubricating oil to pivot points and hinges will help to prevent rust and assure that pump
assemblies move freely.
Cleaning
Periodically check the pump piston and ram for signs of rust or corrosion. Clean as needed and wipe with an oily cloth.
Note: Never use sandpaper or abrasive material on these surfaces!
Storage
When not in use, store with the pump piston and ram fully retracted.
