Lubrication
1. A periodic coating of light lubricating oil to pivot points, axles and hinges will help to prevent rust and assure that
pump assemblies move freely.
2. When used on a daily basis, air pump should be internally lubricated before each use. Use premium quality air
tool lubricant. If no inline oiler is used, pour a teaspoon of air tool oil into the inlet of the air control valve. Simply
operate the jack using the air feature in order to fully distribute the oil.
Cleaning
Periodically check the pump piston and ram plunger 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 pump piston and ram plunger fully retracted and air supply disconnected.
