INSPECTION AND SETUP
This is the safety alert symbol used for the INSPECTION AND SETUP section of this manual to alert you to potential
personal injury hazards. Obey all instructions to avoid possible injury.
Visual inspection should be made before each use of the jack, checking for leaking hydraulic fluid and damaged, loose or missing parts. Any jack
which appears to be damaged in any way, found to be badly worn or operated abnormally MUST BE REMOVED FROM SERVICE. If the jack is
accidentally subjected to an abnormal load or shock, it must be inspected by a manufacturer's authorized repair facility immediately. It is recom-
mended that an annual inspection of the jack be made by a manufacturer's authorized repair facility and that any defective parts, decals, or warn-
ing labels be replaced with manufacturer's specified parts. A list of authorized repair facilities is available from the manufacturer.

OPERATING INSTRUCTIONS
This is the safety alert symbol used for the OPERATING INSTRUCTIONS section of this manual to alert you to potential
personal injury hazards. Obey all instructions to avoid possible injury or death.
1.
Lift the vehicle to the desired work height and support the vehicle in accordance with the lift manufacturer's recommended support
procedure and all the instructions and warnings in this manual.
2.
Use an under hoist stand rated greater than the weight of the engine to support the engine before unbolting the transmission from the
engine or bolting the transmission to the engine.
3.
Position the transmission jack directly under the transmission. Depress the foot pedal up and down in order to raise the saddle to a height
very close to the center of balance point of the transmission oil pan but do not touch the transmission.
4.
Adjust the fingers (#3-29) on the saddle so that the bent up section of the fingers will fit in the mounting flange around the perimeter of the
transmission oil pan. Once the fingers are properly positioned, tighten the wing nuts that secure the fingers to the saddle. Slowly and gently
pump the jack so the connection is made, and then secure the transmission to the jack's saddle with the safety chain (#3-26) provided.
Sometimes it is necessary to turn the fore and aft tilt knobs and side to side locating knob so the saddle is in the proper alignment with the
transmission pan before securing the load to the saddle.
5.
Make sure the safety chain (#3-26) is very tight when securing the transmission to the saddle and before raising or lowering the
transmission.
6.
Remove the transmission from the engine according to instructions in the vehicle service manual.
7.
Once the transmission has been disconnected from the engine, very slowly turn the release knob in a counterclockwise direction to make
sure the jack's saddle and transmission do not hang up on any under-car components, wiring, fuel lines, etc. Continue to lower the jack
all the way down.
8.
When installing a transmission, follow the above instructions but in the applicable order and according to the vehicle
manufacturer's installation procedure.
