NORMAL SHUTDOWN PROCEDURE

To shutdown the generator, use the following procedure:
1.  Place the 

Main, Aux.

 and 

Duplex 

circuit breakers 

(Figure 51) in the 

OFF

 position.

Figure 51. Main, Aux. and Duplex  

Circuit Breakers (OFF)

2.  Place the engine speed control switch (Figure 52) in 

the Start/Idle position (down).

Figure 52. Engine Speed Switch 

Start/Idle Position

3.  Let the engine cool by running it at low speed for 3-5 

minutes with no load applied.

4.  Place the 

Auto-Off/Reset Manual Switch

 in the 

OFF/Reset 

position () to start the engine.

Figure 53. Auto-Off/Reset

 Manual;Switch  

(Off/Reset Position)

5.  Remove all loads from the generator.
6.  Inspect entire generator for any damage or loosening 

of components that may have occurred during 

operation.

NOTICE

NEVER

 stop the engine suddenly except in an 

emergency.

EMERGENCY SHUTDOWN PROCEDURE

1.  If equipped (option), push the 

Emergency Stop

 

Pushbutton Switch 

(Figure 54).

Figure 54. Emergency Stop Button

2.  If unit is not equipped with an emergency stop switch, 

place the 

Auto Off/Reset Manual Switch

 (Figure 50) 

in the 

Off/Reset

 position.

AUTOMATIC SHUT-DOWN SYSTEM

This unit is equipped with safety devices to automatically stop 

the engine in the event of low oil pressure, approximately 

14.2 psi (96.5 kPa), or high water temperature, approximately 

212° F (100° C). The LED alarm indicators on the Engine 

Control Unit (ECU) illuminate to signify the reason for the 

shutdown.

NOTICE

Before inspecting, place all circuit breakers in the

 

OFF

 position and allow sufficient time for adequate 

cooling.  When ready to restart, complete all steps in 

the Generator Startup Procedure section of this manual.
