OPERATING INSTRUCTIONS
5.
Make sure the safety chain 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 depress the release pedal to make sure the jack's saddle
and transmission do not hang up on any undercar components, wiring, fuel lines, etc. Continue to lower the jack 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 transmission 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 or grit before using.
2.
Lubricate moving parts, excluding the telescopic rams, monthly with a general purpose grease. Periodic lubrication should be
subject to a maintenance schedule based on frequency of use. A weekly lubrication inspection is suggested. Premature wearing
of components due to lack of or inadequate lubrication is not eligible for warranty consideration.
3.
Inspect the jack before each use. Do not use the jack if any component is cracked, broken, bent, shows sign of damage or leaks
hydraulic fluid. Do not use the jack if it has loose or missing hardware or components, or is modified in any way. Take corrective
action before using the jack again. Premature wearing or damage to components caused by loose or missing hardware is not
eligible for warranty consideration.
4.
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 150 32 or its equivalent Unocal Unax AW150. Any jack found to be defective as a result of foreign
contaminants in the hydraulic system is not eligible for warranty consideration.
5.
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. Contact Sunex for a replacement label if your jack's label is not
readable.
6.
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.
