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 item #2-8 in the handle socket item #1-37, 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 item #1-27 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 flex
shaft in front and below the handle socket is rotating simultaneously with the turning of the knob. Once the correct alignment is made,
tighten the nut item #1-36 and bolt item #1-39.
5. Before Use: Air may become trapped in the hydraulic system.
PURGING AIR FROM THE HYDRAULIC SYSTEM:
a. Rotate the knob at the top of the handle assembly in a clockwise direction until tight.
Now turn it in a counterclockwise direction two full turns.
b. Activate the foot pump pedal item #1-35 about 15 times.
c. Rotate the knob at the top of the handle assembly in a clockwise direction until tight.
d. Activate 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.
e. Repeat steps "a" through "d" until all air is purged from the system.
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 the foot pedal 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. Remember that foot pedal pump operation is only used to quickly raise the saddle to the load. The handle pump or
air valve operation of the jack is used to lift the load. 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 REMOVING THE JACK STANDS! Once jack stands are positioned, turn the knob at the top
of the handle assembly VERY SLOWLY. 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. NOTE. Once
the hand pump operation has ceased, the handle assembly can be locked in any of the three (3) handle locking positions. Typically, the
handle locking positions are used for moving the jack around the shop, keeping the handle out of the way or preventing the handle from
being pumped.
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 stands from under the load and away from the work area.
Turn the knob at the top of the jack's handle assembly 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 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.
