Note: Inspect before each use for evidence of fluid leaks, damaged hydraulic fittings, bent or broken attach-
ments 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.
Important: Use only a good grade hydraulic oil. We recommend Mobil DTE13M. 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 3/8" (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.
