Introduction
These instructions have been written to help the user more effectively use and maintain OTC jacks. Some of the information applying to construction, installation, operation, inspection, and maintenance of hydraulic jacks was selected from ANSI B30.1 and ASME/ANSI PALD-1. It is strongly recommended that the user read these two documents, which may be ordered from the American Society of Mechanical Engineers, United Engineering Center, 345 East 47th, New York, New York 10017.
Safety Precautions
WARNING: Failure to heed the following warnings can result in personal injury and / or equipment damage. These warnings cannot cover every situation, so have safety foremost in your mind when setting up a job.
Read, understand, and follow the operating instructions, and the ANSI B30.1 and ASME
• PALD-1 safety standards for jacks. If the operator cannot read English, operating instructions
and safety precautions must be read and discussed in the operator’s native language.
Si el operador no puede leer inglés, las instrucciones de operación y las precauciones de
seguridad deberán leerse y comentarse en el idioma nativo del operador.
Si lutilisateur ne peut lire langlais, les instructions et les consignes de sécurité doivent
lui être expliquées dans sa langue maternelle.
Wear eye protection that meets the requirements of ANSI Z87.1 and OSHA.
Inspect the jack before each use; do not use the jack if it is damaged, altered, or in poor
condition. To prevent tipping, set up the jack on a hard, level surface.
The load must not exceed the rated lifting capacity of the jack. Lift only dead weight.
Center the load on the jack saddle, because off-center loads can damage the seals and
cause hydraulic failure. Use the jack for lifting purposes only. This jack is designed to LIFT loads, not support
loads. Immediately support a lifted load with jack stands. Stay clear of lifted loads.
The safety valve is set at the factory; no further adjustment is needed.
Use only approved hydraulic fluid, such as Chevron AW Hydraulic Oil MV or equivalent.
Operating Instructions
1. Before using the bottle jack, add 1/2 oz. clean lubricating oil to the air inlet. (Lack of oil causes pump malfunction.)
2. Connect air supply. IMPORTANT: To prevent damage to the air pump, the air supply must be clean and dry.
3. Tightly close the release knob by turning it clockwise.
4. Center the load on the jack saddle. Push the air valve lever to raise the load.
5. Transfer the load to support stands.
6. To lower the jack, open the release valve knob by SLOWLY turning it counterclockwise.

Preventive Maintenance
IMPORTANT: Dirt is the greatest single cause of failure in hydraulic units. Keep the 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. When the jack is not in use, keep the piston and pump rods fully retracted. Store the jack on its base and in a well protected area where it will not be exposed to corrosive vapors, abrasive dust, or any other harmful elements.
2. Maintain the oil level at the bottom of the filler plug hole. If it’s necessary to add oil, remove the filler plug, and fill the reservoir with Chevron AW Hydraulic Oil MV or equivalent.
2. Visually inspect the jack before each use. Take corrective action if any of the following problems are found:
a. Cracked or damaged housing e. Incorrectly functioning swivel heads or adj. screw b. Excessive wear, bending, or other damage f. Loose hardware c. Leaking hydraulic fluid g. Modified or altered equipment d. Scored or damaged piston rod
Troubleshooting Guide
Repair procedures must be performed in a dirt-free environment by qualified personnel who are familiar with this equipment.
Trouble Cause Solution
Erratic Action 1. Air in system
2. Viscosity of oil too high
3. Ram sticking or binding
4. Internal leakage in ram
Ram does not advance 1. Release valve is open
2. Low/no oil in reservoir
3. Air locked system
4. Load is above capacity of system
Ram only extends partially 1. Low oil level in reservoir
2. Piston rod is binding
Ram advances slowly 1. Low air pressure
2. Pump not working correctly
3. Leaking seals
Ram advances but doesn’t 1. Release valve is open hold pressure 2. Ram seals are leaking
3. Pump check valve not working
4. Overload valve leaking or not adjusted
1. With jack sitting on its base and ram retracted, bleed air by opening release valve. Pump for 10 seconds.
2. Change to a lower viscosity oil.
3. Look for dirt, gummy deposits, leaks, misalignment, worn parts, or defective packing.
4. Replace worn packings. Look for excessive contamination or wear.
1. Close release valve.
2. Fill with oil & bleed system.
3. With jack sitting on its base and ram retracted, bleed air by opening release valve, running pump for 10 seconds.
4. Use correct equipment.
1. Fill reservoir with oil, & bleed system.
2. Look for dirt, gummy deposits, leaks, misalignment, worn parts, or defective packing.
1. Adjust air pressure to 90–180 psi.
2. Rework pump.
3. Replace seals.
1. Close release valve.
2. Replace seals.
3. Clean / replace check valve.
4. Replace / adjust overload valve.
Jack leaks oil 1. Worn or damaged seals Ram will not retract, or 1. Release valve is closed
retracts slowly 2. Reservoir too full
3. Ram damaged internally
