OWNER'S MANUAL
SETUP FOR 2 TON JACK (SUM-917072)
PLEASE REFER TO THE EXPLODED VIEW DRAWING IN THIS MANUAL IN ORDER TO IDENTIFY PARTS.
1. Depress the spring button at the bottom of the (#59) upper handle half and insert it in the (#49) lower handle half until the spring button
engages the hole in the lower handle half.
2. Remove the (#50) handle set screw from the (#53) handle yoke. Install the assembled handle into the (#53) handle yoke, making sure the
bottom of the handle engages the release valve u-joint (#61).
3. Install the (#50) handle set screw in the (#53) handle yoke and tighten the screw to secure the handle in the yoke.
4. Air may become trapped in the hydraulic system during shipping and handling. Trapped air will affect the pumping performance of the
jack. If this occurs, follow the air purging procedure below:
a) Remove the reservoir fill plug (#62).
b) With the saddle (#34) in its down position, look inside the oil fill screw hole. You should be able to see the top of the power unit's
pressure cylinder. The recommended hydraulic fluid level should be no higher than the top of the cylinder. Correct the fluid level if it
is not at the proper height with the recommended hydraulic fluid mentioned in the PREVENTATIVE MAINTENANCE section below.
c) Pump the jack against a load that is at least 500 lbs. (225 Kgs). After the load is raised, slightly turn the pump handle in a
counter clockwise rotation so the load is very slowly lowered. While the saddle is lowering, quickly pump the handle 5 or
6 full incremental pump strokes. After pumping, lower the saddle to its full rest position.
d) Repeat steps "a" through "d" until all of the air has been purged from the system.
SETUP FOR 3 TON JACK (SUM-917073)
PLEASE REFER TO THE EXPLODED VIEW DRAWING IN THIS MANUAL IN ORDER TO IDENTIFY PARTS.
IMPORTANT: In most cases the jack should work normally right out of the box but it is not unusual for air to get trapped in the jack's hydraulic
system during shipping and handling. There are several symptoms of an air trapped hydraulic system which include only partial incremental
pump stroke, jack will not lift load, jack will not sustain load or pumping feels spongy under load. The following procedure will purge air from
the hydraulic system and only needs to be done if experiencing the above mentioned conditions.
1. The (#36) saddle should be in its lowest position. Remove the oil filler plug in the reservoir of the (#50) hydraulic power unit.
2. Look inside the oil fill plug hole. You should be able to see the top of the power unit's cylinder. The hydraulic fluid level should be no
higher than the top of the cylinder. Correct the fluid level if it is not at the proper height. CAUTION: In order to prevent seal damage and
jack failure, never use alcohol, hydraulic brake fluid, or transmission oil in the jack. Use hydraulic jack oil, a light turbine oil, Chevron
Hydraulic Oil AW ISO 32 or Unocal Unax AW 150.
3. Close the release valve by turning the (#62) handle clockwise until it stops. Pump the jack against a load of at least 500 pounds
(225 Kgs). After the load is raised to maximum height, slightly turn the (#62) handle in a counterclockwise direction so the load is
very slowly lowered, while simultaneously and quickly pumping the handle 5 or 6 full incremental pump strokes. After pumping,
lower the lift arm to its full rest position.
4. Repeat steps 3) through 4) until all the air has been purged from the system. Reinstall the cover plate.
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 handle in a clockwise direction until tight. Position the jack under the load. Proceed to pump the handle 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 handle 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.
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!
