OPERATING INSTRUCTIONS….cont
LOWERING THE JACK
1. Push the handle into the handle base, use the bolt, washer and nut in the handle
base to secure.
2. Close the release valve by turning the release knob clockwise until firm resistance is
felt.
3. Locate the lifting point, centre the jack saddle under the lifting point.
4. Ensure the handle lock is released and the handle can move freely.
5. Pump the handle or foot pedal to contact the lifting point; continue to pump the
handle until the load reaches the desired height.
6. Transfer the load immediately to appropriately rated jack stands.
1. Raise the load high enough to allow it to clear the jack stands.
2. Carefully remove the jack stands.
3. Slowly turn the release knob anti-clockwise to open the release valve - Never turn
the release knob more than a ¼ of a turn at a time.
4. Allow the load to slowly lower to its original position.
5. Remove the jack from under the vehicle.
Caution:
Take care when lowering the jack that nothing can get trapped
in the moving parts of the jack, or under the load.
Note:
Follow the vehicle manufacturer’s recommended guidelines for lift-
ing. Engage the emergency brake and chock each un-lifted wheel in both
directions to prevent inadvertent vehicle movement.
Note:
Refer to the vehicle manufacturer owner’s manual to locate ap-
proved lifting points on the vehicle.
Note:
After removing the jack from under the vehicle, fully lower the saddle
to reduce ram exposure to contamination.
NEVER
use the hydraulic jack as a stand alone device!
ALWAYS
transfer the lifted load
IMMEDIATELY
to a pair of appropriately rated
jack stands. Use one pair of jack stands per vehicle. Do not exceed
the rated capacity.
