TJHAIR1000 1/2 Ton Air/Hydraulic Telescopic Transmission Jack
when the first stage air ram is only partially raised, the jack's ram may drop suddenly.
4. Adjust the ratchet arms on the saddle so that the bent up section of the arms will fit in the mounting flange around
the perimeter of the transmission oil pan. Slowly and gently pump the jack so the connection is made and then
secure the transmission to the jack's saddle with the tie down strap provided. Sometimes it is necessary to turn the
fore and aft and also the side to side tilt knobs so the saddle is in the proper alignment with the transmission pan
before securing the load to the saddle.
5. Make sure the tie down strap 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 valve knob on the
second stage hydraulic block in a counter clockwise direction. Make sure the jack's saddle and transmission do not
hang up on any under car components, wiring, fuel lines, etc.
IMPORTANT: Continue to lower the load until the second stage bottoms out and then depress the first stage "UP"
pedal for a second to increase air pressure before depressing the "DOWN" pedal to lower the transmission 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.
PREVENTATIVE MAINTENANCE
This is the safety alert symbol used for the PREVENTATIVE MAINTENANCE section of this manual to alert
you to potential personal injury hazards. Obey all instructions to avoid possible injury or death.
1. Always store the jack in a well protected area where it will not be exposed to inclement weather, corrosive vapors,
abrasive dust, or any other harmful elements. The jack must be cleaned of water, snow, sand, grit, oil, grease or other
foreign matter before using.
2. Lubricate moving parts, excluding the telescopic rams, monthly with a general purpose grease.
IMPORTANT: any jack found to be defective as a result of worn parts due to insufficient or lack of lubrication is not
eligible for warranty consideration.
3. It should not be necessary to refill or top off the reservoir with hydraulic fluid unless there is an external leak. An
external leak requires immediate repair which must be performed in a dirt-free environment by qualified hydraulic
repair personnel who are familiar with this equipment.
IMPORTANT: In order to prevent seal damage and jack failure, never use alcohol, hydraulic brake fluid or
transmission oil in the jack. Use Chevron Hydraulic Oil AW ISO 32, its equivalent Unocal Unax AW 150 or hydraulic
jack oil.
4. Every jack owner is responsible for keeping the jack labels clean and readable. Use a mild soap solution to wash
external surfaces of the jack but not any moving hydraulic components.
5. Do not attempt to make any hydraulic repairs unless you are a qualified hydraulic repair person that is familiar
with this equipment. Repairs must be performed by an authorized service center.
PROPER STORAGE
It is recommended that the jack be stored in a dry location with all wheels touching the ground on a relatively level
surface.
