important: Use only good grade 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 failure of the jack and the potential for
sudden and immediate loss of load. We recommend Mobil DTE 13M or equivalent.
Adding oil
1. With saddle fully lowered set jack in its upright, level position. Locate and remove vent screw.
2. Fill with oil until ~3/16" above the inner cylinder as seen from the oil filler hole. If the oil level is too low, the jack
will not raise to its advertised maximum height. Reinstall the vent screw.
Changing oil
For best performance, replace the complete fluid supply at least once per year.
1. With saddle fully lowered, remove the vent screw and drain the fluid into a suitable container.
2. Fill with oil until
~3/16" above the inner cylinder as seen from the oil filler
note: Dispose of hydraulic fluid in accordance with local regulations.
Lubrication
A periodic coating of light lubricating oil to pivot points, axles and hinges will help to prevent rust and assure that
wheels, casters and pump assemblies move freely.
Cleaning
Periodically check the pump piston and ram for signs of rust/corrosion. Clean as needed and wipe with oily cloth.
note: Never use sandpaper or abrasive material on these surfaces!
Storage
When not in use, store the jack with saddle fully lowered. This will help prevent rust and corrosion to those critical
surfaces.
