1. SHUTDOWN BYPASS PREHEAT
SWITCH:
Two functions are built into this switch: The
preheating of the engine, and bypassing of
the engine safety shutdown circuit, enabling a
quicker start. Hold switch in up position 10-20
seconds before starting engine, and continue
holding in up position while starting engine.
Holding the switches on too long can burn out
the heater elements.
