OWNER'S MANUAL
SETUP INSTRUCTIONS
IMPORTANT: Before attempting to raise any vehicle, check vehicle service manual for recommended lifting surfaces.
1 Remove the 2-piece handle from box Depress the upper handle lock button and insert the smaller diameter end of the upper handle into the lower handle end with hole
Make sure the button engages the hole
2 Grease the inside of the handle yoke so the handle will rotate freely inside the yoke Remove the handle yoke screw Insert the end of the lower handle all the way in the
handle yoke until it engages the release valve assembly Secure the handle in the handle yoke by reinstalling the handle yoke screw and tightening the screw Rotate the
handle to see if it is rotating the release valve assembly Pull on the handle to make sure it is secured in the handle yoke If the release valve assembly is not rotating and/
or the handle pulls out of the handle yoke, repeat step 2
3 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 any of the above
mentioned conditions
a) The saddle should be in its lowest position Remove the four screws that secure the cover plate to the jack frame so the oil filler screw can be removed from the
hydraulic power unit reservoir tube
b) Look inside the oil fill screw 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
c) Close the release valve by turning the 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 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
d) Install the oil fill screw Rotate the handle in a clockwise direction until tight and pump the lift arm to maximum height without a load Repeat steps a) through d) 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 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!
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, grit, oil, grease or other foreign matter 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, elevator arm, handle base pivot bolts, release mechanism and all other bearing surfaces Worn parts resulting from inadequate or no lubrication are not eligible for
warranty consideration See page 5 for lubrication instructions
3 It should not be necessary to refill or top off the reservoir with hydraulic fluid unless there is an external leak An external leak requires immediate repair which must be
performed in a dirt-free environment by an authorized service center
IMPORTANT: In order to prevent seal damage and jack failure, never use alcohol, hydraulic brake fluid or transmission oil in the jack Use Chevron Hydraulic Oil AW ISO 32 or its
equivalent Unocal Unax AW 150
