OPERATION

Lifting
Only attachments and/or adapters supplied by the manufacturer shall be used. Lift only on areas of the
!
vehicle as specified by the vehicle manufacturer.
1. Follow the vehicle manufacturer's recommended guidelines for lifting. Engage the emergency brake and chock each
unlifted wheel in both directions to prevent inadvertent vehicle movement.
2. Locate and close the release valve by turning the release valve knob clockwise until firm resistance is felt.
3. Refer to the vehicle manufacturer owner's manual to locate approved lifting points on the vehicle. Center jack saddle
under lift point.
4. Verify lift point then use handle pump to contact lift point. To lift, pump handle or squeeze air control valve (model
HW93667 & HW93662) until load reaches desired height.
5. Transfer the load immediately to appropriately rated jack stands.
NEVER use 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. Rated capacity is per pair
only! Do not exceed rated capacity.
!
Overloading may cause hydraulic system failure.
Lowering
Be sure all tools and personnel are clear before lowering load. Slowly open the release valve!
!
The more you turn the release valve knob counter-clockwise, the faster the load will come down. Maintain
control of the rate of speed at which the load lowers at all times!
1. Raise load high enough to clear the jack stands.
2. Remove jack stands, carefully (always used in pairs).
3. Slowly turn the release valve knob counter-clockwise, but no more than 1/2 full turn. If the load fails to lower:
a. Use another jack to raise the vehicle high enough to reinstall jack stands.
b. Remove the malfunctioning jack and then the jack stands.
c. Using the functioning jack, lower the load by turning the release valve knob counter-clockwise, but no more
than 1/2 full turn.
4. After removing jack from under the load, push saddle down to reduce ram exposure to rust and contamination.
