Please read the warnings and instructions carefully in the manual since they are concerning the important
indications and safety of operation and maintenance. The Manufacturer is in no way responsible for eventual
damages to persons, animals or equipments caused by improper, erroneous, incorrect and unreasonable
application.
1. Application: Air-operated hydraulic pressure jack is a newly-designed lifting equipment. It utilizes
compressed air to promote booster cylinder, to make the hydraulic oil which is stored in oil tank infuse into oil
cylinder to move hydraulic cylinder up & down. It adopts the machinery design combination of hydraulic
pressure with great advantages of delicate design, small dimension, convenient moving, wide scope of usage,
strong jacking capacity and low lifting part. It is a convenient lifting equipment and low labor intensity of
automobile manufacturing, repairing, engineering mechanism or heavy-facility.

3. Safety Notice
(1) Install the operation rod and host together with fixed axis of operation rod. Place the retaining ring in
good order. Insert the air-operated connectors into pipe connectors according to their different outer
size. Pull the locked operation rod to carry out 3 different directions: lever direction of operation rod &
host, direction of 45 degrees and 90 degrees. (As for operation procedure, please see the label of
<Air-operated hydraulic pressure Jack installation instruction> which sticks on the operation rod.)
(2) Make reasonable choice of clean and dry air pressure (Grease filter much be installed on the air resource),
its application scope should be 90-130psi (The MAX. air pressure of safety valve is 130psi) and within
the rated air pressure scope to guarantee life.
(3) Connect it with air pipe. (See picture A)
(4) Place the air-operated hydraulic pressure jack on a stable, flat, resistant, dry surface without drains or
holes when using. If necessary, place a wood board under the air-operated hydraulic pressure jack to
avoid any deflection. (Please carefully read the label of <Warnings> which sticks on the operation
rod.) .
(5) When lifting, place some secured stands or solid supports on the suitable area under raised vehicle to
assure security.
(6) Before lifting, please estimate the weight of object and vehicles to avoid overload. The life of equipment
will be affected strongly if it is overloaded.
(7) The air-operated hydraulic pressure jack uses 32w hydraulic oil. Make sure there is enough filtered &
clean hydraulic oil to support the jack, or the jack is unable to reach it rated hoisting height. If it lacks
of oil, please screw off the bolt of oil tank’s filling opening and fill suitable amount of oil then screw
on.
(8) Don’t shake it sharply when using. To move the air-operated hydraulic pressure jack, please keep the
