MAINTENANCE

Monthly Maintenance

Lubrication is critical to jacks, since they support heavy loads. Any restriction due to dirt or rust can cause 
either slow jack movement or extremely rapid jerks, causing damage to the internal components. To keep 
the jack well lubricated, carry out the following steps.
1. Lubricate the linkages, the saddle and pump mechanism with light oil

2. Grease the wheel bearing and axles. 

3. Keep all jack surfaces and warning labels clean.

Three-Month Maintenance

At three-month intervals, check the pump for any signs of rust or corrosion. Clean the pump as required and 
wipe with an oil cloth.
