ADVERTENCIA ! â¢S tudy, understand, and follow all instructions provided with and on this device before use. ⢠Do not exceed rated capacity. ⢠Use only on hard, level surfaces. â¢L ifting device only. â¢I mmediately after lifting, support the vehicle with appropriately rated jack stands. â¢D o not move or dolly the vehicle while on the jack. ⢠Failure to heed these markings may result in personal injury and/or property damage. W ARNING ! ! SAFETY MESSAGE ! Be sure all tools and personnel are clear before lowering load. No alterations shall be made to this device. Only attachments and/or adapters supplied by the manufacturer shall be used. Lift only on areas of the vehicle as specified by the vehicle manufacturer. NOTE: Jack stands are rated per pair unless otherwise noted. Use 1 matched pair per vehicle only. FIG. 1 FIG. 2 TO ASSEMBLE THE TWO PIECE HANDLE Assemble two piece handle by aligning holes in upper and lower handles. (see Fig. 1) Secure handle with provided bolt.

4 OPERA TION FIG. 3 KNOW YOUR JACK Compare Fig. 3 illustration with your jack BEFORE operation to become familiar with the location of various jack components. BEFORE USE â¢R ead the operator's manual completely and familiarize yourself thoroughly with the product, its components and recognize the hazards associated with its use. â¢O ccasionally 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: â¢C lose release valve by turning the jack handle clockwise until tight. ⢠Pump the handle until the jack saddle reaches its maximum height. ⢠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. â¢T o release air from the hydraulic system: â¢O pen 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. 4) â¢R apidly pump jack handle through several full strokes. ⢠Reinstall the oil filler plug into the cylinder again and jack is now ready to use. Jack Handle Handle Socket Rear Caster Front Wheel Lifting Arm Oil Filler Plug (Not Shown, on Reservoir) Saddle Release V alve SPECIFICA TIONS Rated Capacity: 3 T on / 6000 Lbs Jack Dimensions: 25â x 13 7/16â x 6 7/16â Lifting Range: 5 1/2â - 19â (140mm - 483mm) Oil Capacity: 150 c.c. Net Weight: 80.7 Lbs
OPERA TING PRINCIPLES â¢W ith 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. â¢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 T O USE YOUR JACK RAISING THE JACK â¢C hock the vehicle wheels with appropriate devices to prevent vehicle from moving and to ensure lifting stability. â¢C lose the release valve by turning the jack handle clockwise until tight. (see Fig. 3) â¢R efer to the vehicle manufacturer âs owner âs 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. â¢P ump jack handle until saddle ALMOST contacts the vehicle. Check to see that the saddle is centered and will contact the load lifting point firmly. OPERA TION â¢C ontinue to pump the jack handle to lift the vehicle to the desired height. After lifting, immediately 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. â¢R aise load high enough to clear the jack stands, then carefully remove jack stands ( always used in pairs). ⢠SLOWL Y 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. â¢A fter removing jack from under the load, push saddle down to reduce ram exposure to rust and contamination. 5 ! !
6 MAINTENANCE MAINT AINING OIL LEVEL Important: Use only a good grade hydraulic jack oil. Avoid mixing dif ferent types of fluid and Never use brake fluid, turbine oil, transmission fluid, motor oil or glycerin. Improper fluid can cause failure of the jack and the potential for sudden and immediate loss of load. We recommend Mobil DTE13M or equivalent. 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. 3 & 4). â¢O il should be filled to the level of about 3/ 16â 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. LUBRICA TION â¢A dd lubricating oil to all moving parts as needed. PREVENTING RUST â¢C heck ram and pump piston (see Fig. 4) every few months for any signs of rust or corrosion. Clean as needed by wiping with an oily cloth. â¢W hen not in use, AL W A YS store jack with saddle lowered all the way down. FIG. 4 ANNUAL INSPECTION To ensure that it is in optimum condition, annual inspection of the jack at a Sears Service Center is recommended. REPLACING OIL â¢T o drain oil, with saddle fully lowered, remove oil filler plug and open release valve. T urn 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. â¢R efill with new oil through the oil filler hole. DO NOT allow dirt or foreign material to enter the hydraulic system when filling. â¢A fter 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 the jack is ready to use.
