The foregoing obligation is our sole liability under this or any implied warranty and under no circumstances shall we be liable for any incidental or

CONTACT INFORMATION:
Please contact the dealer/distributor where the item was purchased . Be certain to include with any returned products your name and address,
evidence of the purchase date, and description of the suspected defect .
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 or grit 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 .
IMPORTANT:
Any jack found to be defective as a result of worn parts
due to lack of lubrication or air/hydraulic system contaminated with
water, rust and /or foreign materials from the air supply or other outside
source 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 . 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
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 .
5 . Do not attempt to make any hydraulic repairs unless you
are a qualified hydraulic repair person that is familiar with
this equipment .
6 . Any hydraulic repairs within the warranty period must be
performed by an authorized service center .
