EMERGENCY SHUTDOWN PROCEDURE
NOTICE
The Emergency Stop switch should only be used
to stop the engine in case of an emergency or to lock
out operation during service. The Emergency Stop
switch should NEVER be used for routine stopping of
the engine.
1. To stop the engine in the event of an emergency, push
the Emergency Stop switch (Figure 57), located on
the side of the generator next to the output terminal
panel. Or, if equipped, press the optional Emergency
Stop switch located on the control panel.

2. Place the main, auxiliary, and GFCI circuit breakers
in the OFF position as shown in Figure 54.
3. The emergency stop switch is a push-locked type switch.
The switch contact can only be released by rotating
the button in the clockwise direction. The engine can
not be restarted until the contact is released (closed).
AUTOMATIC SHUTDOWN SYSTEM
This unit is equipped with safety devices to automatically
stop the engine in the event of low oil pressure, approximately
14 psi (97 kPa), high water temperature, approximately
212°F (100°C), or over crank (engine fails to start 3 times).
The alarm lamps on the ECU illuminate to signify the reason
for the shutdown.
NOTICE
Before inspecting the generator, check that the
Auto Start/Stop switch is in the OFF/RESET position,
and place all circuit breakers in the OFF position. Allow
sufficient time for adequate cooling. When ready to
restart, complete all steps in the Generator Startup
Procedure section of this manual.
