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. Position the jack so that the saddle is directly beneath the lifting point.

• Consult the vehicle handbook to determine suitable lifting points.

3. Twist the handle clockwise to close the control valve.

4. Pump the handle to raise the saddle until it reaches 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. Position axle stands directly beneath suitable supporting points on the 

vehicle and very gently twist the handle anti-clockwise.

7. 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.

8. 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.

9. To stop it lowering at any point, turn the handle clockwise again. Always 

avoid a rapid descent by turning the handle slowly.

10. Carefully lower the vehicle onto the axle stand, checking constantly, 

preferably with an assistant, that the vehicles jacking point rests snugly and 
cleanly on the axle stand, and that the stand is stable before the weight is 
taken.

NOTE:

Ensure this operation is carried out under complete control. DO 
NOT allow the load to drop suddenly as this could damage 
internal parts.

11. Completely remove the jack from the vehicle.

WARNING: NEVER WORK ON THE VEHICLE WHEN SUPPORTED ONLY BY A 
JACK. THIS IS HIGHLY DANGEROUS. THE VEHICLE MUST BE SUPPORTED ON 
AXLE STANDS OR SUITABLE SUPPORTS, BENEATH THE CORRECT JACKING/
SUPPORT POINTS.
