ASSEMBLY TO ASSEMBLE THE TWO PIECE HANDLE Spring Pin • Locate the spring pin on bottom end of upper handle and the spring pin receiver on the upper end of lower handle. (Fig. 1). • Align the spring pin with the spring pin receiver. Connect the two handle pieces together by pressing the spring pin and insert until the spring pin is locked in the spring pin receiver. Spring Pin Receiver Upper Handle Lower Handle FIG. 1 1 Handle Socket TO ASSEMBLE THE HANDLE INTO THE SOCKET 2 1. Press and hold the handle socket to loosen the lock pin (Fig. 2). 2.

Allow the saddle to reach its lowest position. • Repeat the above procedure a few times. • To release air from the hydraulic system: • Open the release valve by turning the jack handle counterclockwise, but never by more than 1/2 full turn at a time. • Remove the oil filler screw from the cylinder (Fig. 4). • Rapidly pump jack handle through several full strokes. • Reinstall the oil filler screw into the cylinder again and jack is now ready to use. Compare Fig. 4 illustration with your jack BEFORE operation to become familiar with the location of various jack components. Jack Handle Magnetic Tool Tray (remove to access Oil Filler Plug) Oil Filler Plug (located beneath Tool Tray) Saddle Lifting Arm Handle Socket Front Wheel Release Valve (inside Handle Socket, engage with Jack Handle) Rear Castor FIG. 4 BEFORE EACH USE SPECIFICATIONS Make a visual inspection before each use of the floor jack by checking for abnormal conditions, such as cracked welds, leaks and damaged, loose, or missing parts. Rated Capacity: 4 Ton / 8000 Lbs Jack Dimensions: 27-1/4” x 13-1/4” x 67/16” Lifting Range: 5-3/4” ~ 19-13/16” (Approx.) (145 - 504 mm) Oil Capacity: 235 c.c. Net Weight: 89.1 Lbs (Approx.) DAMAGE TO JACK If you think jack has been subjected to an abnormal load or shock, have it inspected for damage at a Sears or other qualified service center before using it again. 4 OPERATION LOWERING THE JACK • SLOWLY open the release valve by turning the handle counterclockwise, but never more than 1/2 full turn at a time. 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. ! Warning: 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 one 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 ! Warning: 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: • Use another jack to raise the vehicle high enough to reinstall jack stands. • Remove the affected jack and then the stands • Using the other jack, lower the load by turning the operating handle counterclockwise, 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. Note: The release valve must be closed for the handle to remain upright. When the release valve is opened, the handle may lower to the floor. 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 (Fig. 4). • Refer to the vehicle manufacturer’s owner’s manual to locate approved lifting points on the vehicle. Position jack so that the saddle (Fig. 4) 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. 5 MAINTENANCE MAINTAINING OIL LEVEL ANNUAL INSPECTION Important: When adding or replacing oil, ALWAYS use a good grade Hydraulic Jack oil. 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. We recommend Mobil DTE13M or equivalent. 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 oil filler screw and open release valve. Turn jack over and drain old oil out through the oil filler hole. 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 screw and the jack is ready to use. ADDING OIL • Position the jack on level ground and fully lower the saddle. (Ram will be all the way in). Remove oil filler plug from the reservoir (see Fig. 4 & 5). • 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. The jack is now ready to use. LUBRICATION • Add lubricating oil to all moving parts as needed. PREVENTING RUST • Check ram and pump plunger (Fig. 5) every few months for any signs of rust or corrosion. Clean as needed by wiping with an oily cloth. • When not in use, ALWAYS store jack with saddle lowered all the way down. FIG. 5 6 TROUBLESHOOTING PROBLEM-SOLVING HINTS Symptom Possible Causes Corrective Action Jack will not lift load • Release valve not tightly closed • Overloaded - too much weight on jack • Ensure release valve is tightly closed • Reduce weight on jack Jack bleeds off (starts to lower) after lift • Release valve not tightly closed • Hydraulic unit malfunction • Ensure release valve is tightly closed • Replace power unit assembly Jack will not lower after unloading • Oil reservoir overfilled • Linkages binding • Drain fluid to proper level • Clean and lubricate moving parts Poor lift performance • Fluid level low • Air trapped in system • Ensure proper fluid level • With ram fully retracted, open release valve and remove oil filler screw, pump handle several times to expel trapped air. Re-install oil filler screw. • Fluid level low • Ensure proper fluid level Will not lift to full extension PARTS MODEL NUMBER: 50156 Not all components of the jack are replacement items, but are illustrated as a convenient reference of location and position in the assembly sequence.
