Preventive Maintenance
Important: Dirt is the greatest single cause of failure in hydraulic units. Keep the jack clean and well
lubricated to prevent foreign matter from entering the system. If the jack has been exposed to rain,
snow, or grit, it must be cleaned before it is used.
1. When the jack is not in use, keep the piston fully retracted. Store the jack on its base and in a
well protected area where it will not be exposed to corrosive vapors, abrasive dust, or any other
harmful elements.
2. Maintain the oil level at the bottom of the filler plug hole. If it is necessary to add oil, remove the
filler plug, and fill the reservoir with Chevron AW Hydraulic Oil MV or equivalent.
3. Visually 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
d. Scored or damaged piston rod.
e. Incorrectly functioning swivel heads or adj.screw
f. Loose hardware
g. Modified or altered equipment
