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
only
good 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 ram for signs of rust or corrosion. Clean as needed and wipe with an oily cloth.
Note:
Never use sandpaper or abrasive material on these surfaces !
STORAGE
Store the jack with ram fully retracted and air supply disconnected when not in use.
