ASSEMBLY AND OPERATING INSTRUCTIONS
NOTE: For additional references to the parts listed in the following pages, refer to the
Assembly Diagram on page 11.
To Assemble The Handle:
1. Prior to operation, the Handle (36) must be attached to the Transmission Jack.
To do so, loosen the Hex Cap Screw (44) that is located on the Handle Socket
(46). Insert the open end of the Handle fully into the Handle Socket. Then,
firmly retighten the Hex Cap Screw. (See Figure A, next page.)
To Purge The Hydraulic System Of Excess Air:
1. IMPORTANT! Make sure to thoroughly test the Transmission Jack for
proper operation prior to its actual use. If the Transmission Jack appears
Lifting such assemblies, even within the weight limit, can create an off-balance
situation, causing the Transmission Jack to tip over and lead to serious personal
injury and/or property damage. The load should be evenly distributed on the
Transmission Jack, and should not extend beyond the area of the caster wheelbase.
Always use safety straps and/or chains to secure the load.
11. If you are working and the load becomes off-balanced and/or the Transmission
Jack begins to tip over, DO NOT attempt to catch or lift the Jack when it is
falling. In this event, clear the area as quickly and safely as possible in order to
avoid injury from the falling load or getting hit with flying fragments.
12. If in doubt about the safety of your project, it is recommended that you have
the work done by a qualified technician familiar with applicable safe practices.
13. Do not use the Transmission Jack as a permanent stand for a transmission or
differential. Use the Transmission Jack only while making repairs. Then, immediately
remove the transmission or differential from the Transmission Jack.
14. Before lowering the Transmission Jack, make sure tools, tool trays, vehicle
parts, and all other equipment are removed from under the Jack.
15. Maintain labels and nameplates on the Transmission Jack. These carry important
information. If unreadable or missing, contact Harbor Freight Tools for a replacement.
