d. Inspection.
NOTE
Although switches are different, inspection is the same for both.
(1) Inspect switch for damage.
(2) Inspect pressure tube for cracks.
(3) Inspect power cables for cracked insulation, bare wires, and damaged wire lugs.
(4) Inspect coupling nut and mounting hardware for stripped heads and threads and bent or broken
shanks.
e. Cleaning. Clean dirt and rust from mounting hardware and coupling nut.
f. Repair or Replace.
(1) Replace all gaskets.
(2) Replace damaged or unserviceable pressure tube assembly.
(3) Replace damaged or unserviceable pressure switch assembly.
(4) Send damaged switch to Direct Support Maintenance for repair.
(5) Replace damaged or worn electrical power cables.
(6) Replace all damaged screws, bolts, nuts, and washers.
