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/ Changing Oil
For best performance and longest life, replace the complete fluid supply at least once per year.
1. With saddle fully lowered remove cover plate, then oil filler screw.
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. Set jack in its upright, level position.
4. Fill with oil. Proper oil level is just below the rim of the opening. Reinstall the oil filler screw.
5. Perform
Bleeding/Venting Trapped Air
procedure (page 2 & 3).
Lubrication
A periodic coating of light lubricating oil to pivot points, axles and hinges will help to prevent rust and assure that
wheels move freely and the pump functions smoothly. To help ensure trouble free operation, an inline air dryer and
oiler is recommended.
Cleaning
Periodically check the 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 and pump piston surfaces.
Storage
When not in use, store the jack with saddle fully lowered.
REPLACEMENT PARTS
Not all components of the jack are replacement items, but are illustrated as a convenient reference of parts location.
When ordering parts, give part number and parts description. Call your distributor for current pricing.
