SPECIFIC SAFETY INSTRUCTIONS  

AND WARNINGS

WARNING

NEVER use for any purpose other than 

those uses outlined above!
1.  Verify that the product and application are compatible; 

if in doubt, call OEMTOOLS

®

 at 1-866-458-2472.

2.  Before using this product, read the operator’s manual 

completely and familiarize yourself thoroughly with 

the product and its components, and recognize the 

hazards associated with its use.

3.  Wear appropriate safety gear (including heavy duty 

work gloves and ANSI-approved safety goggles) during 

use.

4.  Ensure the Transmission Jack rolls freely. Raise and 

lower the unloaded Transmission Jack throughout the 

lifting range before putting into service to ensure the 

pump operates smoothly. Replace worn or damaged 

parts.

5.  DO NOT exceed the weight capacity of the 

Transmission Jack. Make sure weight is evenly 

distributed. Be aware of dynamic loading! Sudden load 

movement may briefly create excess load causing 

product failure. Exceeding the maximum capacity for 

this product is dangerous and can lead to serious injury 

or property damage.

6.  Never use this device as a work/repair station. Transfer 

the load immediately to a suitable work station.

7.  Always evaluate your task before using this product. 

This Transmission Jack is designed to support a 

transmission or a differential as individual components. 

Use only as intended.

8.  Assemblies such as differential with axle, or 

transmission with bell housing, can be bulky and 

difficult to balance. Lifting or supporting such 

assemblies, even within weight limit, can create an 

off-balance situation, causing the Transmission Jack 

to tip over and MAY lead to serious personal injury or 

property damage.

9.  The load should be evenly distributed on the 

Transmission Jack, and should not extend beyond the 

area of the caster wheelbase. Always use the chains 

provided to secure the load. If extra support is required, 

safety straps (not included) can also be used to secure 

the work piece.

10. Use only a hard, level and flat surface capable of 

bearing the combined weight of the Transmission Jack, 

the load being lifted, the operator and any tools being 

used.

11. If loaded Transmission Jack must be moved, make 

certain that the load is secured by appropriate means, 

is stable, is in the lowest possible position, is moved 

over a smooth, hard level surface, and that the lifting 

platform is level.

12. If you are working and the load becomes off-balance 

and/or the Transmission Jack begins to tip over, 

WARNING

DO NOT ATTEMPT TO CATCH OR LIFT 

THE LOAD WHEN FALLING. SERIOUS PERSONAL 

INJURY CAN RESULT! In this event, clear the area as 

quickly and safely as possible in order to avoid injury from 

the falling load, including getting hit with flying fragments.
13. Before each use, inspect the general condition of the 

Transmission Jack. Check for oil leaks, Transmission 

Jack operation, loose components, free rotation 

and pivoting of saddle adjustment components. If a 

problem occurs, have the problem corrected before 

further use. 

ASSEMBLY

1.  Connect Bases (#43) to the pump frame by using a Flat 

Washer (#48), Lock Washer (#49) and Bolt (#50).

2.  Attach 2 pieces of Locking Castors (#47) and 2 Wheels 

(#52) to the base by using Nut (#44), Flat Washer (#45) 

and Lock Washer (#46).

3.  Install the Saddle (#04) onto the Transmission Jack and 

tighten the bolt on the saddle to secure the saddle.

WARNING

: 

TO PREVENT SERIOUS INJURY: DO 

NOT USE A DAMAGED OR MALFUNCTIONING JACK

.

1.  Make sure the casters are locked before use.
2.  The Transmission Jack is not designed to lift or lower a 

vehicle.

3.  If in doubt about the safety of your project, we advise 

you to have the work done by a professional familiar 

with applicable safety practices.
