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 #54 in the handle socket item #32, 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 frame.

3. Now rotate the "T" handle portion of the handle assembly so it is perfectly aligned with the jack before tightening the item #36 bolt, #35

washer and item #34 nut. Tighten the bolt, washer, and nut so the handle can not rotate. 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.

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 #33 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. If it does not feel your are getting full incremental pump stroke at anytime during the pumping operation, 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

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.

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.

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 all

zerk grease ﬁttings, caster wheels, front axle wheels, elevator arm, handle base pivot bolts, release mechanism and all other bearing

surfaces. Jacks found to be defective due to worn parts resulting from inadequate or no lubrication are not eligible for warranty

consideration.
