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 or corrosion. Clean as needed and wipe with an oily
cloth.
NOTICE:
Do not use sand paper or abrasive material on ram and pump piston surfaces.
Storage
When not in use, store the jack with saddle fully lowered.
