PREVENTATIVE MAINTENANCE

WARNING
Failure to follow these Preventative Maintenance instructions may result in serious injury or death, and/or property damage.
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 all zerk grease
fittings, caster wheels, elevator arm, handle base pivot bolts, release mechanism and all other bearing surfaces. Jacks found to be defective due to worn
parts resulting from inadequate or no lubrication are not eligible for warranty consideration.
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.
In order to prevent seal damage and jack failure, never use alcohol, hydraulic brake fluid or transmission oil in the jack.
WARNING
Use Chevron Hydraulic Oil AW IS0 32 or its equivalent Unocal Unax AW150.
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. Contact Mac Tools® for a replacement label if your jack's label is unreadable.
5. Inspect the jack before each use. Do not use the jack if any component is cracked, broken, bent, shows sign 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.
6. 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.
