Preventive Maintenance; Troubleshooting Guide - SPX OTC 5007 Instrucciones De Operación

Operating Instructions
If the oil supply runs too low, the jack may become air-bound and the handle take only a partial stroke. The following
procedure bleeds air from the system.
1. Remove the jack from service, and place it on a level surface.
2. Lower the lift arm completely.
3. Remove the filler plug, and clean around the filler plug area; this will help prevent contamination of the hydraulic system.
4. Add a high-grade hydraulic fluid equivalent to MIL-F-17111 until the oil level is within 1/4" to 3/8" below the filler hole.
Oil should cover the piston rod.
5. Install the oil fill plug. Clean up any spilled oil.
6. Raise the saddle; then lower the saddle while holding the foot pedal depressed. This will flush out any air in the system.
(Excess oil may run out of the vent.)
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.
Important: 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. Grease the jack once a month using a good bearing grease.
4. Keep warning labels and instructional decals clean and readable. Use a mild soap solution to wash external surfaces
of the jack.
5. Replace the oil in the reservoir at least once per year.
6. Inspect the jack before each use. Take corrective action if any of the following problems are found:
a. cracked, damaged housing
b. excessive wear, bending, other damage
Repair procedures must be performed in a dirt-free environment by qualified personnel who are familiar with this
equipment. CAUTION: All inspection, maintenance, and repair procedures must be performed when the jack is free
of a load (not in use).
Trouble
