OWNER'S MANUAL
SETUP
PLEASE REFER TO THE EXPLODED VIEW DRAWING IN THIS MANUAL IN ORDER TO IDENTIFY PARTS.
1. In order to install the handle assembly (#62) in the handle socket (#36), first align the main handle tube with the largest hole in the handle socket
and the lock pin rod with the smaller hole in the handle socket.
2. Make sure the lock pin rod is in the down/lock position before insertion in the handle socket. Once the main handle tube and lock pin rod are
aligned with their respective holes in the handle socket, push the handle assembly in the handle socket so the end of the handle tube engages the
release valve mechanism in the bottom of the handle socket and the lock pin rod engages one of the three (3) locking holes in the (#1) frame.
3. Disengage the lock pin rod by pulling up on the lever and engaging the lever with the slot in top of the handle assembly. The handle assembly
should be free to pump up and down.
4. In order to check for proper handle assembly alignment with the handle socket, see if the lock pin rod will engage with the three locking holes
in the frame. Also, turn the release valve knob at the top of the handle assembly left and then right to see if the release valve u-joint in front and
below the handle socket is rotating simultaneously with the turning of the knob. Once the handle is properly aligned with the handle socket (#36),
tighten the bolt (#40) and nut (#38).
5. Install the quick disconnect air nipple of your choice in the air valve (#61) and connect the shop air line.
6. Before Use: Air may become trapped in the hydraulic system resulting in insufficient pump stroke, spongy pump feeling or inability to pump lift
arm to maximum height. Follow the air purging instructions below:
STEP 1 FOR MANUAL OPERATION
a. With the release valve knob in the closed position, turn the knob in a counterclockwise direction 2 to 3 complete revolutions.
b. Depress the foot pedal 15 to 20 times.
c. Close the release valve knob by turning it in a clockwise direction until it stops. Depress the foot pump until the lift arm is raised to maximum
height. You should experience a full pump stroke with each incremental pump of the pedal.
d. Repeat steps "a" through "c" until all air is purged from system.
STEP 2
a. Close the release valve knob by turning it clockwise until it stops. Turn the knob counterclockwise 2 or 3 rotations.
b. Depress the air valve for about 15 seconds.
c. Close the release valve knob by turning it clockwise until it stops. Depress the air valve to see if lift arm will raise. If not, repeat steps "a" and
"b" several times to achieve maximum performance.
d. If the jack's lift arm will not raise by depressing the air valve, apply 4 to 5 drops of pneumatic oil in the end of the valve's quick-disconnect
nipple, reattach the air line and repeat step 2. NOTE: The pneumatic oil may temporarily mist out from the air motor's vent, but this is
normal and should not be considered a leak.
OPERATING INSTRUCTIONS
This is the safety alert symbol used for the OPERATING INSTRUCTIONS section of this manual to alert you to potential personal injury
hazards. Obey all instructions to avoid possible injury or death. IMPORTANT: Before attempting to raise any vehicle, check vehicle service
manual for recommended lifting surfaces.
OPERATION:
1. To raise load: Turn the knob at the top of the handle assembly in a clockwise direction until tight. Position the jack under the load. Proceed
to pump the handle or activate the air valve in order to raise the lift arm to the load. As the saddle at the end of the lift arm gets closer to the
load, reposition the jack so the saddle will contact the load firmly and the load is centered on the saddle. Make sure the saddle is correctly
positioned. Raise the load to the desired work height. Place jack stands of appropriate capacity at the vehicle manufacturers's recommended
support areas that provide stable support for the raised vehicle. DO NOT CRAWL UNDER VEHICLE WHILE LIFTING VEHICLE OR PLACING
OR REMOVING THE JACK STANDS! Once jack stands are positioned, turn the jack handle VERY SLOWLY in a counterclockwise direction to
lower the load to rest on the jack stands. Inspect the relationship between the jack stands and load to make sure the setup is stable and safe.
If the setup is not stable or safe, follow the preceding steps until corrected.
2. To lower load: Follow the procedures mentioned in "To raise load" section of the OPERATING INSTRUCTIONS in order to raise the load off the
jack stands. Once the load has cleared the jack stands, remove the jack stands from under the load and away from the work area. Turn handle
very slowly in a counterclockwise direction until the load is completely lowered to the ground. Once the jack's lifting saddle has cleared the load,
remove the jack from under the load. CAUTION: Keep hands and feet away from the hinge mechanism of the jack. DO NOT CRAWL UNDER
VEHICLE WHILE LIFTING VEHICLE OR PLACING OR REMOVING THE JACK STANDS!

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.
