KNOW YOUR JACK
Compare Fig. 3 illustration with your jack
BEFORE operation to become familiar with
the location of various jack components.
SPECIFICATIONS
Rated Capacity: 3 Ton / 6000 LBS
Jack Dimensions: 28 1/2” x 14” x 6 5/16”
Lifting Range: 3 7/8” - 18 1/2 ” (99 - 470 mm)
Oil Capacity: 265 c.c.
Net Weight: 56.6 lbs
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.)
• When the ram reaches maximum 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.
• Continue to pump the jack handle to lift
the vehicle to the desired height. After
lifting, immediately support the load with
appropriately rated vehicle support stands
BEFORE working on the vehicle.
LOWERING THE JACK
• SLOWLY open the release valve by
turning the handle counterclockwise,
but never more than 1/2 full turn at a
time.
