Safety Precautions
Caution: To prevent personal injury and damage to equipment,
•Study, understand, and follow all instructions, including ASME PALD Part 10 for service
jacks.
•If the operator cannot read these instructions, operating instructions and safety
precautions must be read and discussed in the operator’s native language.
•Before using the service jack to lift a vehicle, refer to the vehicle service manual to
determine recommended lifting surfaces on the vehicle chassis.
•Wear eye protection that meets ANSI Z87.1 and OSHA standards.
•Inspect the jack before each use; do not use the jack if it’s damaged, altered, or in poor
condition. Take corrective action if any of the following conditions are found: cracked
or damaged housing; excessive wear, bending, or other damage; leaking hydraulic
uid; scored or damaged piston rod; loose hardware; modied or altered equipment.
•A load must never exceed the rated lifting capacity of the jack.
•Only use the jack on a hard, level surface.
•Use the jack for lifting purposes only. Stay clear of a lifted load. Place support stands
under the axles before working on the vehicle.
•Center the load on the jack saddle. Off-center loads can damage seals and cause jack failure. Lift
only dead weight.
•Do not use blocks or other extenders between the saddle and the load being lifted.
•
Do not modify the jack or use adapters unless approved or supplied by OTC. Do not adjust the safety
valve.
•Lower the jack slowly and carefully while watching the position of the jack saddle.
• Use only approved hydraulic uid (Mobil DTE #11 or equivalent). The use of alcohol, hydraulic brake
uid, or automatic transmission uid (ATF) could damage seals and result in jack failure.
This guide cannot cover every situation, so always do the job with safety rst.
Operating Instructions
1. Connect the shop air supply to the jack. (90–175 psi of clean, dry air is required for the capacity of this
jack.)
2. Position the jack under the vehicle using the manufacturer’s recommended lifting points on the chassis.
3. Close the release valve by turning the knob clockwise (CW) as far as it will go.
4. Press the air valve lever to raise the jack saddle until it touches the vehicle.
5. Check the placement of the jack; the load must be centered on the jack saddle. CAUTION: Avoid wheel
obstructions such as gravel, tools, or uneven expansion joints. The jack must be free to roll forward
11 inches during lifting, and backward 11 inches during lowering. The load could become unstable,
or even fall off the saddle, if the rolling movement of the jack is impaired.
6. Finish lifting the vehicle.
7. Place approved support stands under the vehicle at points that will provide stable support. Before making
repairs on the vehicle, lower it onto the support stands by SLOWLY and carefully turning the release knob
counterclockwise (CCW).

Preventive Maintenance
CAUTION: The greatest single cause of failure in hydraulic units is dirt. Keep the service jack clean and
well lubricated to prevent foreign matter from entering the system. If the jack has been exposed to rain, snow,
sand, or grit, it must be cleaned before it is used.
1. Store the jack in a well-protected area where it will not be exposed to corrosive vapors, abrasive dust, or
any other harmful elements.
2. Lubricate rotating and sliding parts at least once per month.
3. Lubricate the air inlet on the jack using 1/2 oz. clean lubricating oil; lack of oil may cause pump malfunction.
4.Greasethejackonceamonthusingagoodbearinggrease.(Therearegreasettingslocatedonthepivot
tube of the lift arm, the block on the rod end of the cylinder, and on all four wheels of the jack.)
5. Keep warning labels and instructional decals clean and readable. Use a mild soap solution to wash the
external surfaces of the jack.
6. Replace the oil in the reservoir at least once per year.
7. Inspect the jack before each use. Take corrective action if any of the following problems are found:
a. Cracked or damaged housing d. Scored or damaged piston rod
b. Excessive wear, bending, or other damage e. Loose hardware
 c.Leakinghydraulicuid f. Modiedoralteredequipment
Adding Hydraulic Fluid
1. Remove the jack from service, and place it on a level surface.
2. Lower the lift arm completely.
3. Disassemble the top cover by removing the four pan head screws.
4.Cleanaroundthesurfaceoftheoilllplug;thiswillhelppreventcontaminationofthehydraulicoilsystem.
5.Removetheoilllplug,andcheckthehydraulicoillevel.Theuidshouldbevisibleandjustcoveringthe
hydrauliccylinder.Iftheuidlevelislow,addahigh-gradehydraulicuidequivalenttoMobilDTE#11until
the oil level just covers the cylinder.
6.Installtheoilllplug.Cleanupanyspilledoil,andsecurethetopcoverbackontotheframe.
7. Test the jack for normal operation. If the lift pad doesn’t rise to the correct height, repeat Steps 2–6, adding
two more ounces of oil. If this doesn’t solve the problem, call the OTC Technical Services Dept.
