OPERATION
Lifting
WARNING: Only attachments and/or adapters supplied by the manufacturer shall be used.
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 rm 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 to appropriately rated jack stands.
Lowering
WARNING: Clear all tools and personnel before lowering load. Open release valve slowly. The further you turn the
release valve knob counter-clockwise, the faster the load will descend. Maintain control of the load at all times.
1. Raise load high enough to clear the jack stands.
2. Remove jack stands.
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.
