Preventative Maintenance - Napa CARLYLE TOOLS 791-3001 Manual Del Usuario

7. When the vehicle or load is lifted to its desired height, immediately place safety support stands (jack stands) in their designated
locations and adjust the stands' support columns up as close to the designated vehicle support points as possible. Although jack stands
are individually rated, they are to be used in a matched pair to support one end of the vehicle only. Stands are not to be used to
simultaneously support both ends or one side of a vehicle. Slowly and carefully turn the release knob in a counterclockwise direction to
gently lower the vehicle onto the safety support stands (jack stands). Make sure the vehicle is safely supported by the safety support
stands' (jack stands) saddles and not the locating lugs of the saddles. Inspect the relationship of the safety support stands (jack stands)
with the ground and the safety support stand (jack stand) columns and saddles with the vehicle to prevent any unstable conditions. If
conditions look unstable, close the jack's release knob and depress the air valve to raise the vehicle off the safety support stands (jack
stands). Make the appropriate setup changes and slowly and carefully lower the vehicle onto the safety support stand saddles.
8. After the work is done, close the release knob and depress the air valve until the jack is high enough to remove the vehicle or load from the
safety support stand saddles. Be sure load is stable. If it is not, lower load back onto safety support stands. Make appropriate setup
corrections and repeat the step again. Remove the safety support stands from under the vehicle, being very careful not to move
the vehicle.
9. Turn the release knob in a counterclockwise direction very slowly and carefully to lower the vehicle or load down to the ground.

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.
IMPORTANT: The number one cause of jack failure in air/hydraulic jacks is dirt and moisture in the air motor and/or hydraulic system.
The shop air supply should be equipped with water and dirt filter traps that should be emptied or cleaned according to a monthly
maintenance schedule. An in line oil lubricator will extend the life of air/hydraulic jacks. Inoperable jacks caused by poorly equipped or
maintained shop air systems are not eligible for warranty consideration. Contaminants can also enter the air/hydraulic system when
the shop air line is disconnected from the jack air line and the line is dropped on the floor. Contaminants in the air couplers, once reconnected,
will be driven into the system.
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 the
threads on the extension screw. Do not lubricate any portion of the lift saddle and make sure the saddle is free from grease, any kind of
lubricant, or debris before using the jack. 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. Authorized Service Centers are recommended. IMPORTANT: In order to prevent seal damage and jack failure, never use
alcohol, hydraulic brake fluid, or transmission oil in the jack. Use NAPA hydraulic Jack Oil #765-1541.
4. Every jack owner is responsible for keeping the jack label clean and readable. Use a mild soap solution to wash external surfaces of the
jack but not any moving hydraulic components.
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.
