MAINTENANCE
NOTICE: Use only good quality hydraulic jack oil. Avoid mixing different types of fluid and NEVER use brake fluid,
turbine oil, transmission fluid, motor oil or glycerin. Improper fluid can cause premature failure of the jack and the
potential for sudden and immediate loss of load. Premium hydraulic jack oil is recommended.
Adding oil
1. With ram fully lowered, set pump unit in its normal, level position. Locate and remove oil filler screw.
2. Fill until oil is within 3/8" of the oil filler screw hole opening, re-install 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.
NOTICE: Dispose of hydraulic fluid in accordance with local environmental regulations.
3. Set pump in its level upright position.
4. Fill with good quality jack oil to within 3/8" of the oil filler screw hole opening.
5. Perform Bleeding/Air from System procedure (page 4). Reinstall oil filler screw.
Lubrication
A 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.
NOTICE: Do not use sandpaper or abrasive material on ram or pump piston surfaces.
Storage
When not in use, store with the pump piston and ram fully retracted.
