PREVENTATIVE MAINTENANCE (CONT.)
1. Always store the jack in a well protected area where it will not be exposed to inclement weather, corrosive vapors, abrasive dust, or any
other harmful elements. The jack must be cleaned of water, snow, sand, grit, oil, grease or other foreign matter before using.
2. The jack must be lubricated periodically in order to prevent premature wearing of parts. A general purpose grease must be applied to
caster wheels, front axle, elevator arm, handle base pivot bolts, release mechanism and all other bearing surfaces.
from inadequate or no lubrication are not eligible for warranty consideration. IMPORTANT: In order to prevent seal damage and jack fail-
ure, never use alcohol, hydraulic brake fluid, or transmission oil in the jack. Use hydraulic jack oil, a light turbine oil, Chevron AW ISO 32 or
Unocal Unax AW 150.
3. Every jack owner is responsible for keeping the jack labels clean and readable. Use a mild soap solution to wash external surfaces of the
jack but not any moving hydraulic components.
4. Inspect the jack before each use. Do not use the jack if any component is cracked, broken, bent, shows signs of damage or leaks hydraulic
fluid. Do not use the jack if it has loose or missing hardware or components, or is modified in any way. Take corrective action before using
the jack again.
