Checking the oil level
The trolley jack comes with oil inside but needs checking if the trolley jack is not operating
properly.
1.
Ensure the trolley jack is on a flat surface. Turn the handle anti-clockwise with one full
turn to open the release valve and lower the hydraulic cylinder to its lowest position. It
may be necessary to apply force to the head cap to lower.
2.
Remove the oil plug. Stand the trolley jack in a vertical position with handle socket
down. The oil level should match with the bottom of the fill hole. If not, top up with
more oil. Do not overfill.
3.
Cover with the oil plug and check the trolley jack can pump properly. Purge air from
the trolley jack if necessary.
Chocking
Chock the wheels on the vehicle that will not be raised. This will prevent the vehicle from
moving when raised.
