MAINTENANCE
Monthly maintenance is recommended. Lubrication is critical to jacks as they support heavy loads. Any restriction due to
dirt, rust, etc, can cause either slow movement or cause extremely rapid jerks damaging the internal components. The
following steps are designed to keep the jack well maintained and operational.
Important: Dirt is the greatest single cause of failure in hydraulic units. Keep the jack clean and well lubricated to prevent
foreign matter from entering the system. If the jack has been exposed to rain, snow, sand, or grit it must be cleaned before
it is stored or used.
Only use replacement parts that are approved by the manufacturer. Disconnect the air supply before performing any
maintenance operation.
Lubricate the ram, linkages, saddle, wheels and pump mechanism with light Hydraulic oil.
Visually inspect for cracked welds, bent, loose, missing parts or hydraulic oil leaks.
Any hydraulic jack found to be damaged, worn or operates abnormally must be removed from service until repaired by
an authorised service representative.
Regularly clean all surfaces and maintain all labels and warnings.
Check and maintain the hydraulic ram oil level.
Check the ram every three months for any sign of rust or corrosion. Clean as needed and wipe with a clean oily cloth.
When not in use always leave the saddle and ram all the way down.
Always store your jack in the fully retracted position. This will help protect critical areas from corrosion. Do not use brake
or transmission fluids or regular motor oil as they can damage the seals.
ONLY USE HIGH QUALITY HYDRAULIC FLUID – ISO68
