Oil change
• Put the jack upright.

far as the edge of the opening.) Remove any
air as described under Troubleshooting (Air in

• Put the cap back in place.
• Regularly clean the pivoted joints and the
screwed extension to keep the jack in good
condition.
Only hydraulic oil should be used for
refilling. Do not use brake fluid.
