Preventive Maintenance
Important: Dirt is the greatest single cause of failure in hydraulic units. 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.
• Store the jack in a well-protected area where it will not be exposed to corrosive
vapors, abrasive dust, or any other harmful elements.
• Refer to the illustration, and regularly (at least once per month) lubricate the
moving parts shown.
• Add grease to upper arm grease nipple (shown) every three months.
• If necessary, add approved anti-wear hydraulic jack oil. Important: the use of
alcohol, hydraulic brake fluid, detergent motor oil, or transmission oil could
damage the seals and result in jack failure.
• Inspect the jack before each use. Take corrective action if any of the following
problems are found:
a. Cracked or damaged frame b. excessive wear , bending, or other damage
c. Leaking hydraulic uid d. Scored, damaged piston rod
e. Malfunctioning swivel heads or
adjusting screws
g. Modied or altered equipment

f. Loose hardware
