Symptoms & remedies

SymptomCauseRemedy
Crankcase pressure might blow out hot oil and cause serious burns.Do not attempt to check oil while the generator set is running. Add oil until it reaches the top of the oil port.
Fuel level indicator looks damaged or loose.Install a new indicator before starting generator set.
Generator set operates on a slight grade, and the fuel tank is completely filled.Do not fill completely if the generator set will operate on a slight grade.
Faulty electrical equipment connected to the generator presents an electrical shock hazard.Check all electrical equipment for frayed cords or breaks in the insulation before using. Properly applied and maintained ground fault circuit interrupters can afford additional protection against the hazard of electrical shock.
