PREVENTATIVE MAINTENANCE (CONT)
4.
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.
Use Chevron Hydraulic Oil AW 150 32 or its equivalent Unocal Unax AW150. Any jack found to be defective as a result of foreign
contaminants in the hydraulic system is not eligible for warranty consideration.
5.
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 an authorized service center for a replacement label if your
labels become unreadable.
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.
