a. Cleaning.
Dry cleaning solvent, Federal Specification P-D-680, used to clean parts is
potentially dangerous to personnel and property. Avoid repeated and pro-
longed skin contact. Do not use near an open flame or excessive heat. Flash
point of the solvent is 100F - 138F (38C - 59C).
(1) Clean the air compressor by wiping off accumulated dirt and other foreign matter with a cloth dampened with
solvent, P-D-680, or equivalent, and dry thoroughly.
(2) Pay particular attention to cooling fins on intercooler, aftercooler, cylinder head, and cylinder. Accumulated
foreign matter in these areas prevents proper cooling.
b. Inspection.
(1) Visually inspect air compressor for any broken or cracked cooling fins and damage to other parts.
(2) While unit is operating, listen for knocks or rattle that could indicate internal damage.
(3) Listen for short start-stop cycling which would indicate leakage or faulty adjustment of pressure switch.
(4) While air compressor is running, use a soapy water solution applied with a brush to check air compressor
aftercooler safety valve for leakage. Leakage will be indicated by bubbling of the solution. Pull up on ring located on end
of safety valve to relieve pressure. Release ring; safety valve should reseat immediately. Again check for leakage with
solution. Notify Organizational Maintenance for replacement of leaking or defective safety valve.
(5) Notify Organizational Maintenance if any air compressor damage is detected.
c. Servicing. Service the
air compressor as
