31.
AIR COMPRESSOR DOES NOT OPERATE.
Step 1.
Check for tripped main power supply and compressor circuit breaker.
a.
If breaker is tripped, turn main power supply and compressor
circuit breaker to ON. Refer to TM 10-3510-209-10.
b.
If circuit breakers are not tripped, proceed to next step.
Step 2.
Check for internal failure of air compressor. Listen for unusual
noise or overheating.
a.
If compressor operates but does not produce sufficient air
volume or pressure, replace air compressor. Refer to
paragraph 2-24.
b.
If air compressor is serviceable and problem persists, notify
your supervisor.
32.
AIR PRESSURE IS TOO LOW (BELOW 60 PSI [414 kPa]) or TOO HIGH (ABOVE 80 PSI
[552 kPa]).
Step 1.
Check for air leaks at fittings, lines, and tank.
a.
If leaks are found, repair air leaks. Refer to paragraph 2-25.
b.
If leaks are not found, proceed to next step.

b.
If filters are serviceable, proceed to next step.
Step 3.
Check for improperly adjusted pressure switch. Test run compressor:
on at 60 psi (414 kPa); off at 80 psi (552 kPa).
a.
If pressure is incorrect, adjust pressure switch. Refer to
paragraph 2-24.
b.
If pressure is correct, proceed to next step.
