THE NATURE OF HAZARDOUS SITUATIONS
The use of portable automotive supporting devices are subject to certain hazards that cannot be prevented by mechanical means,
but only by the exercise of intelligence, care, and common sense. It is therefore essential to have owners and personnel involved in the
use and operation of the equipment who are careful, competent, trained, and qualified in the safe operation of the equipment and its
proper use. Examples of hazards are dropping, tipping or slipping of loads caused primarily by improperly securing loads, overloading,
off-centered loads, use on other than hard level surfaces, and using equipment for a purpose for which it was not designed.
METHODS TO AVOID HAZARDOUS SITUATIONS
• Read, study, understand and follow all instructions before operating this device.
• Inspect the jack before each use. Do not use if damaged, altered, modified, in poor condition, leaking hydraulic fluid or unstable due
to loose or missing components. Make corrections before using.
• Use only on a hard level surface free from obstructions so the jack is free to reposition itself during lifting and lowering operations.
• Lift only on areas of the vehicle as specified by the vehicle manufacturer.
• User and bystanders must wear eye protection that meets ANSI Z87.1 and OSHA standards.
• Do not use stand beyond its rated capacity. Do not shock load.
•This is a lifting device only. Immediately after lifting, support the vehicle with jack stands capable of sustaining the load before
working on the vehicle.
• Center load on saddle. Be sure setup is stable before working on vehicle.
• Do not move or dolly the vehicle while on the jack.
• Do not use any materials that may serve as risers, spacers or extenders between the stock lifting saddle and the load.
• Do not use any adaptors that replace the stock lifting saddle unless approved or supplied by the jack manufacturer.
• Always lower the jack slowly and carefully.
• Do not use (or modify) this product for any other purpose than that for which it was designed without consulting the manufacturer's
authorized representative.
• Failure to heed these warnings may result in serious or fatal personal injury and/or property damage.
WARNING: This product can expose you to chemicals including nickel, which is known to the State of California to cause cancer and
birth defects or other reproductive harm. For more information go to www.P65Warnings.ca.gov.
CONSEQUENCES OF NOT AVOIDING HAZARDOUS SITUATIONS
Failure to read this manual completely and thoroughly, understand its OPERATING INSTRUCTIONS, SAFETY WARNINGS,
MAINTENANCE INSTRUCTIONS and not comply with them, and neglecting the METHODS TO AVOID HAZARDOUS SITUATIONS
could cause accidents resulting in serious or fatal personal injury and/or property damage.

INSPECTION
Visual inspection should be made before each use of the jack, checking for leaking hydraulic fluid and damaged, loose or missing parts. Each
jack must be inspected by a manufacturer’s repair facility immediately, if subjected to an abnormal load or shock. Any jack which appears to be
damaged in any way, is found to be badly worn, or operates abnormally MUST BE REMOVED FROM SERVICE until necessary repairs are made by
a manufacturer’s authorized repair facility. It is recommended that an annual inspection of the jack be made by a manufacturer’s authorized repair
facility and that any defective parts, decals or warning labels be replaced with manufacturer’s specified parts. A list of authorized repair facilities is
available from the manufacturer.
SETUP
Please refer to the exploded view drawing on page 6 in this manual in order to identify parts:
1. Remove the 2-piece handle from box. Insert narrow portion of top section (#32) into bottom section (#30) and secure with the spring
button.
2. Grease the inside of the handle yoke (#25) and remove the handle set screw (#29) from the yoke (#25). Insert the handle (#30) all the way
in the handle yoke (#25) until it engages the universal joint assembly (#48). Secure the handle (#30) to the handle yoke (#25) with the
handle set screw (#29).
3. 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) Rotate the handle. in a clockwise direction until tight. Rotate the handle in a counterclockwise direction two complete revolutions.
b) Pump the handle approximately 10-15 complete pump strokes.
c) Rotate the handle in a clockwise direction until tight. Proceed to pump the jack to maximum lift height.
d) Repeat steps "a" through "c" until all air has been purged from the system.
OPERATION
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.
1. Put vehicle transmission in park or in gear and then apply the emergency brake.
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 jack handle VERY SLOWLY in a counterclockwise direction to 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. DO NOT CRAWL UNDER VEHICLE WHILE LIFTING VEHICLE OR PLACING
OR REMOVING THE JACK STANDS! 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, 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, its equivalent Unocal Unax AW 150 or hydraulic jack oil.
4. Every jack owner is responsible for keeping the jack labels clean and readable. Use a mild soap solution to wash external surfaces of the
jack but not any moving hydraulic components.
5. Inspect the jack before each use. Do not use the jack if any component is cracked, broken, bent, shows sign of damage or leaks
hydraulic fluid. Do not use the jack if it has loose or missing hardware or components, or is modified in any way. Take corrective action
before using the jack again.
6. Any hydraulic repairs within the warranty period must be performed by an authorized service center.
PROPER STORAGE
It is recommended that the jack be stored in a dry location with all wheels touching the ground on a relatively level surface.

TROUBLESHOOTING
Important: Service jacks are self-contained devices used for lifting, but not sustaining, a partial vehicular load. In accordance with ASME PASE-
2019 Load Sustaining Test: “A load not less than the rated capacity…shall not lower more than 1/8" (3.18mm) in the first minute, nor a total of
.1875" (4.76mm) in 10 minutes.” Lowering within this range is considered normal operation and is NOT a warrantable defect.
PROBLEM ACTION
1. Unit will not lift rated load. Purge air from hydraulic system by following procedure under
SETUP.
2. Unit will not sustain rated load or feels “spongy” under rated load. Purge air from hydraulic system as above.
3. Unit will not lift to full height. Purge air from hydraulic system as above.
4. Handle tends to raise up while the unit is under rated load. Pump the handle rapidly several times to push oil past ball
valves in power unit.
5. Unit still does not operate. Contact Cornwell Customer Service.
