Operation

WARNING: Before standing or working underneath any elevated vehicle or other object, be sure that the vehicle is properly and safely secured following recommendations of the lift manufacturer. For your safety and the safety of others, use good professional practice and common sense. Only use on a flat, level surface capable of supporting the weight of the jack, the workpiece and related tools.

1)The jack may easily be moved by rolling it on its casters. Locate the jack under the transmission. Using a 1/2” Drive Ratchet or Breaker Bar (neither one included) engaged in Bushing (35), rotate the Screw Rod (29) clockwise in order to raise the jack until the Saddle (3) nearly contacts the underside of the transmission. Adjust the position of the jack so that it is centered directly under the center of gravity of the transmission.

2)It is important for your safety to get a good contact between the Saddle (3) and the transmission. This will assure that the transmission is properly supported and balanced once removed from the vehicle and on the jack. Loosen the Wing Nuts (5) and raise the jack again until the Saddle (3) contacts the transmission and presses slightly against it.

3)Secure the transmission to the Saddle (3) by passing the Ratchet Tie-down (7) over the top of the transmission, and securing it using the buckle. Be sure that it is tight. Please review section on Ratchet Tie-down operation next page. Tighten the Wing Nuts (5) and raise the jack until the transmission’s weight is supported by it.

4)Remove the bolts and fittings attaching the transmission to the vehicle, as recommended by the vehicle’s repair instructions.

5)Lower the transmission slightly by turning the Bushing (35) counterclockwise. Recheck the transmission to assure that it is securely and safely attached to the Saddle (3). Make any necessary adjustments. When it is safe to do so, lower the transmission all the way by turning the Bushing (35). For safety, 2 people should be working together to perform these operations.

6)While stabilizing the transmission on the jack, roll the transmission out from under the vehicle to the work location where it will be repaired. It is a good idea to have an assistant help you lower and move the transmission.

WARNING: The use of this jack is limited to the removal, installation, and transportation in the lowest position, of transmissions and differentials. Do not store the transmission or any other part on the jack,unless the jack is in the lowered position. However, the jack is not appropriate as a long-term storage device. Never move the jack unless it is in its lowest position.

Do not overload. Overloading can cause damage to the jack and cause consequential personal or property injury. This jack is designed to use only on hard, level surfaces capable of supporting the load. Use on other surfaces may cause instability and possible property damage or personal injury.
