Parts List & Operating Instructions

IMPORTANT: The greatest single cause of failure in hydraulic units is dirt. Keep the transmission jack

clean and well lubricated to prevent foreign matter from entering the system. If the jack has been exposed to

rain, snow, sand, or grit, it must be cleaned before it is used.

1. Store the jack in a well-protected area where it will not be exposed to corrosive vapors, abrasive dust, or

any other harmful elements.

2. Lubricate moving parts at least once per month.

3. Regularly wipe the cylinder columns with a clean cloth to remove dirt and abrasives.

4. Replace the oil in the reservoir at least once per year.

5. Inspect the jack before each use. Take corrective action if any of the following problems are found:

a. Cracked or damaged housing

b. Excessive wear, bending, or other damage

c. Leaking hydraulic fluid

Repair procedures must be performed in a dirt-free environment by qualified personnel who are familiar with

this equipment.
