4 PREVENTIVE MAINTENANCE
Important: The greatest single cause of failure in hydraulic units is dirt. Keep the service 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. Regularly lubrificate the moving parts in the wheels, arm, handle, and pump roller pin.
3. Replace the hydraulic fluid in the reservoir at least once per year. To check the hydraulic fluid level, lower the lifting arm completely. Remove the rubber
filler plug from the power unit. The hydraulic fluid level shoulb be at the bottom of the filler plug hole. If necessary, add hydraulic fluid and install the filler plug.
IMPORTANT : the use of alcohol or hydraulic brake fluid could damage the seals and result in jack failure.
4. Inspect the jack before each use. Take corrective action if any of the following problems are found;
a. Cracked, damaged housing
b. Excessive wear, bending, or other damage
c. Leaking hydraulic fluid
d. Scored, damaged piston rod
5. Keep warning labels and instructional decals clean and readable. Use a mild soap solution to wash external surfaces of the jack.
5 TROUBLESHOOTING GUIDE
Repair procedures must be performed in a dirt-free environment by qualified personnel who are familiar with this equipment.
