MAINTENANCE (SERVICE JACK)
NOTICE: Use only good quality hydraulic jack oil. Avoid mixing different types of uid and NEVER use brake uid,
turbine oil, transmission uid, motor oil or glycerin. Improper uid 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 saddle fully lowered set jack in its upright, level position. Remove vent screw.
2. Fill with oil until ~3/16" above the inner cylinder as seen from the oil ller hole. Reinstall vent screw.
Changing oil
For best performance and longest life, replace the complete uid supply at least once per year.
1. With saddle fully lowered, remove vent screw.
2. Lay the jack on its side and drain the uid into a suitable container.
NOTICE: Dispose of hydraulic uid in accordance with local environmental regulations.
3. Fill with oil until ~3/16" above the inner cylinder as seen from the oil ller hole. Reinstall vent screw.
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. Lubricate lift arm through grease ttings.
Cleaning
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 and pump piston surfaces.
Storage
When not in use, store the jack with saddle fully lowered.
MAINTENANCE (JACK STANDS)
Periodically inspect each stand. Ensure all parts move freely. Do not apply oil or grease to any portion of this product.
If rust appears, sand affected area and cover with suitable utility paint.
Storage
Store stands in upright position and in a clean, dry area.
