OPERATING PRINCIPLES
• With release valve closed, an upward
stroke of the jack handle draws oil from the
reservoir tank into the plunger cavity.
Hydraulic pressure holds a valve closed,
which keeps the oil in the plunger cavity.
• A downward stroke of the jack handle
releases oil into the cylinder, which forces
the ram out. This raises the saddle. (NOTE:
To avoid damage to the cylinder if the load
exceeds the rated capacity of the jack, oil
is automatically released back into the
reservoir through the safety overload
valve.)
• W h e n t h e r a m r e a c h e s m a x i m u m
extension, oil is bypassed back into the
reservoir to prevent an over-extended ram
stroke and possible damage to the jack.
• Opening the release valve allows oil to flow
back into the reservoir. This releases
hydraulic pressure on the ram, which
results in lowering the saddle.
HOW TO USE YOUR JACK
RAISING THE JACK
• Chock the vehicle wheels with appropriate
devices to prevent vehicle from moving and
to ensure lifting stability.
• Close the release valve by turning the jack
handle clockwise until tight. (see Fig. 3)
• Refer to the vehicle manufacturer’s owner’s
manual to locate approved lifting points on
the vehicle. Position jack so that the saddle
(see Fig. 3) is centered under the load at
an appropriate lift point.
• Pump jack handle until saddle ALMOST
contacts the vehicle. Check to see that the
saddle is centered and will contact the load
lifting point firmly.
OPERATION
• Continue to pump the jack handle to lift the
vehicle to the desired height. After lifting,
immediately support the load with
appropriately rated jack stands BEFORE
working on the vehicle.
Rated capacity of jack stands is per
pair, it is NOT the sum of individual
capacities unless specifically noted to the
contrary by the jack stand manufacturer.
Do Not exceed rated capacity. Ensure that
the vehicle support points are fully captured
between the outer lugs of both jack stands.
Use a matched pair of jack stands per
vehicle to support 1 end only. Use 1 pair
per vehicle only. Failure to do so may
result in sudden loss of load, which may
cause personal injury and/or property
damage.
LOWERING THE JACK
To avoid crushing injuries and property
damage: Keep hands and feet clear of work
area when lowering load.
• Raise load high enough to clear the jack
stands, then carefully remove jack stands
(always used in pairs).
• SLOWLY open the release valve by turning
the handle counterclockwise, but never
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 affected jack and then the
stands.
c. Using the other jack, lower the load by
turning the operating handle counter-
clockwise, but no more than 1/2 full turn.
• After removing jack from under the load,
push saddle down to reduce ram exposure
to rust and contamination.
