OPERATION
Before use, inspect the jack for oil leaks or any other sign of damage. Should
any be apparent, have the jack repaired by a qualified technician.
1. Ensure the vehicle to be raised is stable and on firm level ground with the
wheels chocked.
2. To ensure safe lifting, position the jack at a 90
o
angle to the vehicle and
under the appropriate jacking point.
• Consult the vehicle handbook to determine suitable jacking points.
3. Twist the handle clockwise until it stops to close the control valve.
4. Pump the handle to raise the saddle is in contact with the jacking point.
5. Make sure that the saddle is in full contact with the lifting point and that
there is nothing that will prevent a clean lift. Keep all personnel at a safe
distance before lifting the vehicle.
6. Continue pumping the handle until the vehicle is at the required height.
• CAUTION: Observe the vehicle carefully during the lifting operation.
The jack should move in the direction of the vehicle during lifting.
Should this not be the case, there is a strong possibility that the
vehicle will slide off the jack.
7. Position axle stands directly beneath suitable supporting points on the
vehicle and very gently twist the handle anti-clockwise.
8. This will open the control valve to lower the load onto the stands.
• Make sure that the axle stands are in good condition and that they
can hold the load.
9. Ensure that the axle stands cannot move when supporting the load. Use
suitable wheel chocks to stop the vehicle from moving.
NOTE: The jack may move slightly during operation. It is important
therefore, that the floor is clean and completely free from debris.
10. To stop it lowering at any point, turn the handle clockwise again. Always
avoid a rapid descent by turning the handle slowly.
11. Carefully lower the vehicle onto the axle stand, checking constantly,
preferably with an assistant, that the vehicles jacking point rests snugly and
WARNING: NEVER WORK ON THE VEHICLE WHEN SUPPORTED ONLY BY A
JACK. THIS IS HIGHLY DANGEROUS. THE VEHICLE SHOULD BE SUPPORTED
ON AXLE STANDS OR SUITABLE SUPPORTS, BENEATH THE CORRECT
JACKING/SUPPORT POINTS.
