BEFORE USE
•Read the operator's manual completely
and familiarize yourself thoroughly with the
product, its components and recognize the
hazards associated with its use.
•Occasionally during shipment and/or
handling air can get trapped in the system,
which can interfere with the jacks lifting
performance.
•It is recommended to cycle the jack a few
times without applying load:
•Engage release valve with notched end
of jack handle. Close release valve by
turning the jack handle clockwise until
tight.
•Insert jack handle into handle sleeve.
Pump the handle until the jack saddle
reaches its maximum height.
•Engage release valve with notched end
of jack handle. Open release valve by
turning jack handle counterclockwise, but
no more than 1/2 full turn. Allow the saddle
to reach its lowest position.
•Repeat the above procedure a few times.
•To release air from the hydraulic system:
•Engage release valve with notched end
of jack handle. Open the release valve
by turning the jack handle
counterclockwise, but never by more than
1/2 full turn.
•Remove the oil filler plug from the cylinder.
(see Fig. 2)
•Insert jack handle into handle sleeve.
Rapidly pump jack handle through several
full strokes.
•Reinstall the oil filler plug into the cylinder
again and jack is now ready to use.

valve with this end

OPERATION
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.
•Adownward 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
•With notched end of the jack handlle (see
Fig. 1) close release valve by turning the
handle clockwise.
•Chock the vehicle’s wheel with appropriate
devices to ensure lifting stability.
•Refer to the vehicle manufacturer’s owners
manual to locate approved lifting points on
the vehicle. Position jack so that the saddle
is centered under the load at an appropriate
lift point.
•Insert jack handle into handle sleeve. 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,
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).
•With notched end of jack handle, 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.

MAINTENANCE
MAINTAINING OIL LEVEL
Important: When adding or replacing oil,
ALWAYS use a good grade Hydraulic Jack
oil. We recommend Mobil DTE13M or
equivalent. DO NOT use Hydraulic Brake
Fluid, Alcohol, Glycerine, Detergent, Motor
Oil or dirty oil. Use of an improper fluid can
cause serious internal damage to your jack.
ADDING OIL
•Position the jack on level ground and fully
lower the saddle. (Ram will be all the way
in). Remove oil filler plug located under
cover plate (see Fig. 2).
•Oil should be filled to the level of about
3/16” above the inner cylinder as seen from
the oil filler hole. If low, add oil as needed.
•Re-install oil filler plug and cover plate. The
jack is now ready to use.
LUBRICATION
•Add lubricating oil to all moving parts as
needed.
PREVENTING RUST
•Check ram and pump plunger (see Fig. 2)
every few months for any signs of rust or
corrosion. Clean as needed by wiping with
an oily cloth.
FIG. 2
•When not in use, ALWAYS store jack with
saddle lowered all the way down.
ANNUAL INSPECTION
To ensure that it is in optimum condition,
annual inspection of the jack at a Sears
Service Center is recommended.
REPLACING OIL
•To drain oil, remove cover plate and oil filler
plug and open release valve. Turn jack over
and drain old oil out through the oil filler
hole and into a suitable container.
Note: Dispose of hydraulic oil in accordance
with local regulations.
•Refill with new oil through the oil filler hole.
DO NOT allow dirt or foreign material to
enter the hydraulic system when filling.
•After refilling, remove any air from the
hydraulic system by opening the release
valve and rapidly pumping the jack handle
several times.
•Re-install oil filler plug and cover plate and
the jack is ready to use.

OPERATION
HOW TO USE YOUR JACK STANDS
TO SUPPORT A VEHICLE
1. Raise the vehicle or load with an
automotive jack.
2. Adjust jack stand height by pulling up
on ratchet bar. The weight of the locking
handle should lock the ratchet bar into
a secure position. To verify this, simply
push down on the locking handle to
ensure that the ratchet bar is secured.
3. Carefully position the stands beneath
the load so that when load is lowered it
will contact the center of the jack stand
saddles.

4. Always use jack stands as a pair and
only on those parts of a vehicle which
can be fully captured between the outer
lugs of each stand’s saddle.
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.
5. Slowly and carefully lower the load
completely onto the stands, ensure that
the load is centered and captured as
described in Step 4.
6. Check to ensure that load is secure on
stands before working under vehicle.
TO REMOVE AND STORE JACK
STANDS
1. Raise vehicle clear of stands with
suitable jack.
2. Raise the locking handle to allow ratchet
bar to glide down to lowest position.
3. Carefully remove stands.
4. Carefully lower vehicle with jack.
5. Ensure that all tools, equipment and
personnel are clear before lowering
load.
