Monthly maintenance is recommended.Lubrication is crifical 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 lubricated:
1. Lubricate the ram,linkages,saddle and pump mechanism with light oil.Grease wheel
bearings and axles.
2. Visually inspect for cracked welds,bent,loose,missing parts or hydraulic oil leaks.
3. If jack is subjected to abnrmal load or shock,remove from service and have it examined by
a customer service representative prior to use.
4. Clean all surfaces and maintain all labels and warnings.
5. Check and maintain the ram oil level.
6. Check ram every 3 months for any sign of rust or corrosion.Clean as needed and wipe with
an oil cloth.
When not in use, always leave the saddle and ram all the way down.
Always store your jack in the fully lowered position. this will help protect critical areas from
excessive corrosion.
Do not use brake or transmission fluids or regular motor oil as they can damage the seals.
Always purchase and use products labeled Hydraulic Jack Oil.
