OPERATION  
KNOW YOUR JACK  
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.  
Compare Fig. 1 illustration with your jack  
BEFORE operation to become familiar with  
the location of various jack components.  
• Occasionally during shipment and/or  
handling air can get trapped in the system,  
which can interfere with the jacks lifting  
performance.

OPERATION  
• Continue to pump the jack handle to lift the  
OPERATING PRINCIPLES  
vehicle to the desired height. After lifting,  
support the load with appropriately rated  
jack stands BEFORE working on the  
vehicle.  
• 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.  
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  
• 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.  
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:  
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.  
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  
• When not in use, ALWAYS store jack with  
saddle lowered all the way down.  
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.  
ANNUAL INSPECTION  
To ensure that it is in optimum condition,  
annual inspection of the jack at a Sears  
Service Center is recommended.  
REPLACING OIL  
ADDING 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.  
• 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.  
• Re-install oil filler plug and cover plate and  
the jack is ready to use.  
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.
