CARE AND MAINTENANCE
NOTICE:
Use only good quality hydraulic jack oil. NEVER use brake fluid, turbine
oil, transmission fluid, motor oil or glycerin. Improper fluid can cause jack failure and
sudden loss of load. Mobil DTE13M or equivalent is recommended.
Adding Oil
1. With saddle fully lowered set jack in its upright, level position. Locate and remove
oil filler plug.
2. Proper oil level will vary from just covering inner cylinder to ~3/16” above inner
cylinder as seen from oil filler plug hole. If oil level is too low, jack will not raise to
advertised maximum height. Reinstall oil filler plug.
NOTICE:
Do not
overfill reservoir. Overfilled reservoir can cause a variety of
performance problems and create an oil spill on shop floor (see
Troubleshooting
,
page 6).
Changing Oil
For best performance and longest life, completely replace fluid supply at least once
per year.
1. With saddle fully lowered, remove oil filler plug.
2. Lay jack on its side and drain fluid into a suitable container.
NOTICE:
Dispose of hydraulic fluid in accordance with local environmental
regulations.
3. Fill with oil. Proper oil level will vary from just covering inner cylinder to ~3/16”
above inner cylinder as seen from oil filler plug hole. Reinstall oil filler plug.
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 pump piston and ram for signs of rust or corrosion. Clean as
needed and wipe with an oily cloth.
NOTICE:
Never use sandpaper or abrasive material on ram or pump piston.
Storage
Store the jack with pump piston, ram plunger, and saddle fully lowered and release
valve open, but never more than 1/2 turn. This will help prevent rust and corrosion to
critical surfaces.
