MONTHLY MAINTENANCE

Periodic 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.

6.1.1

Lubricate the linkages, the saddle, and the pump mechanism with light oil.
