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.

2. Specification & Parameter.

Model No. 10771
Jacking Capacity 50T/25T/10T/
Air Pressure 90-130 psi
Lowest Height 5.5”
Hoisting Height 50T: 2.2” 25T: 2.04” 10T: 2.2”
Weight 143 lbs.

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

wheels balanced with the operation rod in intermediate position.
(9) Don’t place the equipment upside down when using.
(10) Please keep the equipment cleaned & out of the reach of children when not using.
(11) It is natural & normal to appear a little bit of oil leaking when transporting, loading and using it in the

first time.

4. Transport:
The equipment should be packed in carton. Please see the carrying position as below picture:.

CARRYING POSITION

5. Equipment Installation, Disassembly and Test.

(1) Equipment installation, when Disassemble, please see (picture A/B/C/D/E/F).

(2) Equipment Test:

a. When the Equipment is off load within rated air pressure scope, operate the handle of hand

valve clockwise to make t he Jack move up to the rated hoisting height. After reach the rated
hoisting height, boosting system stops working automatically

(The MAX. air pressure of safety
valve is 130psi). Operate the handle of hand valve anticlockwise to make the jack move down.
Dust band and sealing of cylinder work in good order without gas leaking..

b. Test the equipment with heavy load by special te sting machine. It is able to rea ch the rated jacking

capacity and hoisting height within the rated air pressure scope. Dustband and sealing of cylinder
work in good order without gas leaking. (The MAX. air pressure of safety valve is 130psi)

6. Operation and Maintenance.
(1) Operation of air-operated hydraulic pressure jack.

a. Operate the handle of hand valve clockwise to carry out lifting. When the equipment lif ting

to the rated height then it will stop lifting automatically by itself with the limitation system.

b. Operate the handle of hand valve anticlockwise to carry out movi ng down. The equipment

will move down automatically by itself with reasonable design principle of air structure.

(2) Equipment maintenance and troubleshooting.

1) Equipment maintenance.
a. Add a few drops of lubricating oil regularly on the air inlet every 30 days once.
b. Don’t keep it at the acid, alkali and corrosiv e working place.
d. Check the oil tank to make sure whether there is enough hydraulic oil or not every 30 days

once.

c. Keep it clean daily after using.

Notice:

1. Carry the equipment with hands in the (carrying

position), see picture in left side.

2. Please operate it according to the relative warning

indication which sticks on carton.

3. The operator can move the equipment to any

places with the help of operation rod and wheels.
