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 #52 in the handle socket item #31, 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 #35

bolt and item #33 nut. Tighten the bolt 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 #32 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 you are getting a 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 manufacturer's recommended support areas that provide stable support for the

raised vehicle. dO NOT CRAwl uNdER VEHIClE wHIlE lIFTINg VEHIClE OR PlACINg/REMOVINg THE JACk STANdS! Once jack

stands are positioned, turn the knob at the top of the handle assembly in a counterclockwise direction 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.

INSPECTION

visual inspection should be made before each use of the service jack, checking for leaking hydraulic fluid and dam aged, loose or missing parts. each

jack must be inspected by a man u fac tur er's repair facility im me di ate ly, if ac ci den tal ly sub ject ed to an ab nor mal load or shock. Any jack which appears

to be damaged in any way, is found to be badly worn, or operates abnormally MUST Be Re MOveD FROM SeR vICe until nec es sary repairs are made by

a man u fac tur er's au tho rized repair facility. It is rec om mend ed that an annual in spec tion of the jack be made by a man u fac tur er's au tho rized repair

facility and that any de fec tive parts, decals or warning labels be replaced with man u fac tur er's specified parts.
