5. Perform Bleeding/Venting Trapped Air procedure (page 4).
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 in line 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.
Note: Never use sandpaper or abrasive material on ram surfaces!
Storage
When not in use, store the jack with saddle fully lowered.
