Operation
HOW IT WORKS
The jack power unit consists of plunger, oil tank, cylinder and ram.
An upward stroke of the jack handle draws oil from the tank into the plunger. Hydraulic pressure closes
a valve that keeps oil in the cavity.
A downward stroke of the jack handle forces oil in to the cylinder, pushing out the ram and raising the
saddle. NOTE: As a protective feature, when the ram reaches maximum extension, sufficient oil passes
back into the tank to prevent an overextended ram stroke and possible jack damage.
When the release valve is open, oil flows back into the tank, causing the ram to retract, lowering the saddle.
It is the owner and/or operators responsibility to study all warnings, operating and maintenance
instructions found on the product sticker and instruction manual before using this unit. The
owner/operators shall retain product instructions for future reference.

Pumping the Jack Handle
6
Lifting the Vehicle
□
Pump the jack handle until
saddle nears contact with
vehicle. Check to see that
the saddle is centered and
will contact the lifting point
firmly.
□
Continue to pump the jack
handle to lift the vehicle
to a height slightly above
the jack stands or other
supports. Then turn the
handle very slowly counterclockwise to
open the release valve to lower the
vehicle onto the supports.
WARNING:
To avoid pinching or crushing
hands or feet, ALWAYS keep them clear of
the jack hinge and ground contact area
when lowering the vehicle. The jack is a
lifting device only. DO NOT move or dolly
the vehicle while it is on the jack.
