Fault finding

Dealing with problems

If there is too little oil in the jack: Remove the covering plate 5,
undo the blind plug 4 and then replenish the oil reservoir with
appropriate hydraulic jack oil.
To de-aerate the hydraulic cylinder, remove the covering plate 5
and undo the blind plug 4.
The jack could have an air lock.
Open the release valve 1 one full turn. Bring the jack into the
vertical position by raising the rear wheels from the ground.
Move the handle forcefully up and down.
Close the release valve again and operate the jack.
The valves are probably not fully closed.
Lower the lifting arm and close the release valve.
With one foot on a front wheel, pull the lifting arm upwards by
hand. Open the release valve again and lower the lifting arm.
The jack should now be ready for use again.
The lifting arm return spring is probably broken or has become
detached.
Replace or re-attach the lifting arm return spring and grease it.
Clean and oil all moving parts on the lifting mechanism.
