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

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
or top off the reservoir with hydraulic
unless there is an external leak. An external leak
requires immediate r
familiar with this equipment. Authorized Service Centers are recommended.
IMPORTANT:
In order to prevent seal damage and jack
failure, never use alcohol, hydraulic brake
or transmission oil in the jack. Use hydraulic jack oil, Chevron Hydraulic Oil AW ISO
32 or its equivalent Unocal Unax AW 150.
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.
