OWNERS MANUAL
BEFORE OPERATION
It is the owner and/or operator's responsibility to completely read and understand these instructions and warnings before operating the jack.
ASSEMBLY INSTRUCTIONS
1. Jack handle is shipped in two pieces. Locate the lower section of the handle and place into the handle socket of jack assembly
shown in Figure #2. Ensure the knurled handle base screw retainer bolt is unthreaded allowing handle to drop into position.
Once handle is fully seated, tighten the knurled handle base screw retainer bolt. Note: Handle should turn freely and should
not come out of handle base.
2. Place the upper section of handle into the lower section aligning the detent ball with hole in the lower section of the handle.
Once the upper handle piece is seated into the lower handle piece, the detent ball should lock both pieces together.
WARNING
1. Jack is designed for lifting vehicles only and is not intended for any other purpose.
2. Consult vehicle owner’s manual prior to jacking up of a vehicle.
3. Use jack on solid, level ground. Ensure front wheels of the vehicle being raised are in a parallel position.
4. No person should remain in vehicle that is being jacked up.
5. When lifting a vehicle, be sure to place the center of the jack saddle directly under the axle or frame.
6. After lifting vehicle, place jack stands under the axles and or frame rails.
7. No person should be under a vehicle that is supported by jack only.
8. Never move the jack while it is supporting a vehicle.
9. When lowering a vehicle, make sure nobody is near or under the vehicle. Slowly lower vehicle with careful
attention to the position of jack saddle.
10. The safety valve is factory adjusted and no further adjustment is required.
11. While not in use, always store with handle in an upright position.
OPERATING INSTRUCTIONS
1. To release air trapped in hydraulic system some jacks have a bleed valve located in the top of the base as shown in Figure #2.
Opening the bleed valve will release trapped air.
2. Opening the release valve by turning handle counter-clockwise and slowly pumping 10-15 full strokes should remove any
excess trapped air. If additional bleeding or filling is required, reference the Filling and Bleeding Section on page 2.
3. Close release valve by turning handle clock-wise until seated. Use caution when tightening handle, over tightening handle
will damage release valve.
4. Jack is now ready to lift.
5. To lower jack, open release valve by turning handle counter-clockwise.

WARNING
1. Use jack for loading less than rated capacity. Do not overload, otherwise a dangerous situation my occur.
2. Jack is designed for lifting vehicles only and not for any other purpose. Support car with jack stands once the
load has been lifted. Stay clear of lifted loads.
3. Center the load on the jack saddle. Off center loads can damage the seals and cause jack failure.
4. Lift only dead weight.
5. Jack is to be used by professional personnel only. To prevent dangerous situations that may occur, use by non
professional personnel is not recommended, especially children.
Filling / Bleeding the Hydraulic Oil
Tools required: #3 Phillips head screwdriver and 8mm Hex wrench.
Filling: – #3 Phillips head screw to the left of the pump piston on the back of the jack reservoir. See Figure #1.
1. Clean around fill plug.
2. Stand and support the jack on the large roller.
3. Remove Phillips screw (Figure #1) and fill reservoir to top with hydraulic jack oil. Replace Phillips screw, lower jack to ground.
Bleeding: – 8mm Allen socket plug on the top of reservoir to the left of the valve adjustment shaft. See Figure #2.
1. Clean around bleed plug.
2. Loosen the 8mm plug on the top.
3. Use the jack handle to close the release valve, then pump the jack slowly. The pad should move up slowly and
oil should come out around the 8mm plug.
4. If the oil has air bubbles, open the 8mm plug more and continue to pump the jack slowly for several strokes. Note: Do not
completely remove plug. If air is still present, close the 8mm plug, stand jack on large roller again and top off oil through fill.
plug. Repeat until air bubbles cease, then close both plugs.
5. Use for a few weeks then recheck for air by repeating the filling and bleeding process.
NOTE: If repairing pieces inside 8mm plug hole, these pieces they are very easy to damage or lose. BE CAREFUL.
