Part No. 9010
Sears, Roebuck and Co., Chicago, I L. 60684 U.S.A.
RULES FOR SAFE OPERATION
IMPORTANT: Sometimes during shipment and/or
handling, air gets into the hydraulic system, causing
poor lifting performance. This is indicated by a
springy feet asyou pump the jack under a load.
PURGE ANY AIR FROM THE SYSTEM by simply
opening Release Valve (turn handle counter-clock-
wise) and operate pump handle rapidly severaltimes.
Raising the Jack
1. Close Release Valve TIGHTLY (by turning handle
clockwise)
2. Position jack under load so that saddle will contact
load firmly and is centered so it cannot slip.
3. Operate jack handle until saddle approaches contact
with load. Once again check to see that saddle iscor-
rectly positioned.
4. Raise load to desired height. Transfer to Jack Stands
if load is to be held up for an extended period.
Lowering the Jack
Open Release Valve VERY SLOWLY (by turning handle
counter-clockwise). When Release Valve is opened,
saddle can be easily lowered by the spring tension inside
the frame.
CAUTION: Keep hands or feet away from the hinge
mechanism of the jack.
Operating Principles
With ReleaseValve TIGHTLY CLOSED:
1. Upward stroke draws oil from Reservoir Tank into
Plunger Cavity. Hydraulic pressure keeps Valve
closed, keeping oil in cylinder.

2. Downward stroke of Plunger forces oil into Cylinder.
Ram is forced out, raisingsaddle.
if load exceeds rated capacity, oil is automatically
released back into Reservoir thru Safety Overload
Valve.
3. When Ram reaches maximum stroke, oil is by-passed
back into Reservoir, thus preventing overextended
Ram Stroke.
When Release Valve is opened, oil is allowed to flow
back into Reservoir, releasing hydraulic pressure on
Ram and permitting saddle go be lowered.
