purge the air from the hydraulic
system.
• The jack is now ready to use.

‘Locked’ position as shown.
2. Turn the knob on the handle
counterclockwise to open the
release valve.

and are stable before full weight of the vehicle is taken on it.
• Make sure that the axle stands are in good condition and that they
can hold the load.

• DO NOT jerk the handle, make sure that it lowers slowly and in a
controlled manner on to the axle stands
