Preventive Maintenance
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. Inspect the jack before each use. Take corrective action if any of the following problems are found:
a. Cracked or damaged housing d. Scored or damaged piston rod
b. Excessive wear, bending, or other damage e. Loose hardware
c. Leaking hydraulic fluid f. Modified or altered equipment

2. Use only hydraulic jack oil. Do not use hydraulic brake fluid.
3. If the jack fails to operate, check the oil level and/or bleed the unit before seeking repair service.
IMPORTANT: Do not use this jack as a wash rack when washing or steam cleaning transmissions.
