OPERATION
Lifting
Only attachments and/or adapters supplied by the manufacturer shall be used. Lift only on area 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.
Close the release valve by turning the handle 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, pump handle to contact lift point. To lift, pump handle 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.
Lowering
Be sure all tools and personnel are clear before lowering load.
Slowly open the release valve!
The more
you turn the handle 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.
3.
Slowly
turn the handle 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.
Use the functioning jack to lower the vehicle.
4. After removing jack from under the vehicle, fully lower the saddle to reduce ram exposure to rust and contamination.
