Preventative Maintenance - Napa CARLYLE TOOLS 791-6620E Manual De Instrucciones

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.
5. 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
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.
STEP 2
a. Close the release valve knob by turning it in a clockwise direction until it stops.
b. Depress the air valve lever 6 to 8 successive times and hold it down on the last depression. If the jack's lift arm will not raise, repeat
steps 1 and 2 again.
c. If depressing the air valve will not raise the lift arm, follow step 3.
STEP 3
a. Close the release valve knob by turning it clockwise until it stops. Depress the foot pedal to raise the lift arm to its maximum height.
b. Depress the air valve while simultaneously turning the release valve 2 to 3 revolutions in a counterclockwise direction. The lift arm
should lower rapidly.
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 step 3
several times to achieve maximum performance.
STEP 4
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 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 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. DO NOT CRAWL UNDER VEHICLE WHILE LIFTING VEHICLE OR REMOVING THE JACK STANDS!
