overload protector
cuts out repeatedly.
The incorrect fuse type is
being used.
The wrong gauge wire or
length of extension cord is
used.
There is a defective check
valve or unloader.
There is low voltage from
the power source.
There is a lack of proper
ventilation, or the room
temperature is too high.
