PREVENTATIVE MAINTENANCE (CONT.)
IMPORTANT: any jack found to be defective as a result of worn parts due to insufficient or lack of lubrication is 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.
IMPORTANT: In order to prevent seal damage and jack failure, never use alcohol, hydraulic brake fluid or transmission oil in the jack. Any jack
found to be defective as a result of foreign contaminants in the hydraulic system is not eligible for warranty consideration. Use NAPA hydraulic
Jack Oil #765-1541.
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 NAPA for a replacement label if your jack's label is not readable.
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.
