SPECIFIC PRODUCT WARNINGS AND PRECAUTIONS

1. Do not exceed the maximum lift capacity (1200 pounds) for the T ransmission

Jack. Overloading the T ransmission J ack could cause personal injury and/or property

damage.

2. Use of the Transmission Jack is limited to the removal, installation, and

transportation (in the Jack’s lowered position) of transmissions and

differentials within the weight limitation specified. No alteration to the Jack or

adapters shall be made.

3. Never open or adjust the Bypass Valve. (Noted in Figure A, page 6.) The Bypass

Valve is an essential safety device that is factory-set. Adjusting the Bypass Valve

may cause serious personal injury, property damage, or hinder proper operation of

the Transmission Jack.

4. Make sure the Transmission Jack is used only on a dry, oil/grease free, solid,

level, concrete surface capable of supporting the weight of the entire vehicle,

Transmission Jack, and any additional tools and equipment.

5. Prior to using the Transmission Jack, make sure to read and understand all

warnings, safety precautions, and instructions as outlined in the vehicle

manufacturer’ s instruction manual.

6. Do not use the Transmission Jack with the vehicle’s engine running. Also,

make sure to place proper support devices (not included) under the vehicle.

7. Do not allow anyone in the vehicle while using the Transmission Jack.

Keep all bystanders a safe distance away from the vehicle.

9. Always keep hands, fingers, and feet away from the moving parts of the

Transmission Jack when applying or releasing a load. Remain clear of the

Transmission Jack when raising or lowering a transmission or differential.

10. Always evaluate your task before using the Transmission Jack. The

Transmission Jack is designed to support a transmission or differential as individual

components. Assemblies such as a differential with an axle, or a transmission with

bell housing, can be bulky and difficult to balance on the Jack’s platform or cradle.
