Units with External Brass Check Valve Replacement:
Motor:
The motor has a manual reset thermal overload protector switch. If the motor overheats for any
reason, the overload protector will shut off the motor. The motor must be allowed to cool down
before resetting the overload switch and restarting. If the overload protector shuts the motor off
frequently, check for a possible voltage problem. Low voltage can also be suspected when:
Air Filter - Inspection and Replacement:
Keep the air filter clean at all times. Do not operate the compressor with the
air filter removed.
A dirty air filter will not allow the compressor to operate at full capacity. Before
you use the compressor, check the air filter to be sure it is clean.
If it is dirty, check and replace the filter element.
WARNING: Safety Valve – Inspection ... IF THE SAFETY VALVE DOES NOT
WORK PROPERLY, OVER-PRESSURIZATION MAY OCCUR, CAUSING AIR TANK
RUPTURE OR AN EXPLOSION. OCCASIONALLY PULL THE RING ON THE
SAFETY VALVE TO MAKE SURE THAT THE SAFETY VALVE OPERATES
FREELY. IF THE VALVE IS STUCK OR DOES NOT OPERATE SMOOTHLY, IT
MUST BE REPLACED WITH THE SAME TYPE OF VALVE.
