PREVENTATIVE MAINTENANCE

This is the safety alert symbol used for the PREVENTATIVE MAINTENANCE section of this manual to alert you to
potential personal injury hazards. Obey all instructions to avoid possible injury or death.
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 or grit before using.
2. Lubricate moving parts, excluding the telescopic rams, monthly with a general purpose grease.
3. It should not be necessary to refill or top off the reservoir with hydraulic fluid unless there is an external leak. An external leak
requires immediate repair which must be performed in a dirt-free environment by qualified hydraulic repair personnel who are
familiar with this equipment.
IMPORTANT: In order to prevent seal damage and jack failure, never use alcohol, hydraulic brake fluid or
transmission oil in the jack.
4. 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.
5. Do not attempt to make any hydraulic repairs unless you are a qualified hydraulic repair person that is familiar with this
equipment. Repairs must be performed by an authorized service center.
