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 l'utilisateur ne peut lire l'anglais, 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. Set vehicle parking brake and block tires.
•
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 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.
•
Use only approved hydraulic fluid, such as Chevron AW Hydraulic Oil MV or equivalent.
Operating Instructions
To raise the jack, use narrow end of jack handle to tighten release valve clockwise (CW). Insert handle into socket, and operate pump.
To lower the jack, SLOWLY open the release valve knob by turning it counterclockwise (CCW).
To use the jack in a horizontal position, the pump MUST be lower than the reservoir. Position the jack as shown in Figure 1.

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 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

Trouble Cause Solution
Erratic Action 1. Air in system 1. With jack sitting on its base and ram
retracted, bleed air by opening release
valve & remove oil plug. Pump for 10
seconds.
2. Viscosity of oil too high 2. Change to a lower viscosity oil.
3. Ram sticking or binding 3. Look for dirt, gummy deposits, leaks,
misalignment, worn parts, or defective
packing.
4. Internal leakage in ram 4. Replace worn packings. Look for
excessive contamination or wear.
Ram does not advance 1. Release valve is open 1. Close release valve
2. Low/no oil in reservoir 2. Remove oil plug, fill jack with oil to
bottom of oil fill hole, & bleed system.
3. Air locked system 3. With jack sitting on its base and ram
retracted, bleed air by opening release
valve & remove oil plug. Pump for 10
seconds.
4. Load is above capacity of system 4. Use correct equipment.
Ram only extends partially 1. Low oil level in reservoir 1. Fill reservoir with oil, & bleed system.
and stops 2. Piston rod is binding 2. Look for dirt, gummy deposits, leaks,
misalignment, worn parts, or defective
packing.
Ram advances slowly 1. Pump not working correctly 1. Rework pump.
2. Leaking seals 2. Replace seals.
Ram advances but doesn't 1. Release valve is open 1. Close release valve
hold pressure 2. Ram seals are leaking 2. Replace seals.
3. Pump check valve not working 3. Clean / replace check valve.
4. Overload valve leaking or 4. Replace / adjust overload valve.
