AUTO-IDLE OPERATION

IMPORTANT: Never start engine with electrical loads connected. Start engine before adding electrical loads.

1.If engine is cold, turn the auto-idle switch OFF.

2.Start engine. Allow engine to warm up with no load for five minutes.

3.Turn auto-idle switch ON. Engine will slow to idle speed. Engine idle speed is preset. Idle speed adjustment should not be necessary.

4.Operate generator according to specifications outlined in owner's manual.

5.Engine will automatically increase to normal operating speed when you plug load into any generator outlet.

NOTE: The 250 Volt/50 Amp receptacle is not connected through the auto-idle circuit. The auto-idle switch must be turned off to get full power out of this receptacle (See Figure 30).

6.The auto-idle system should be turned OFF when generator is shut down.

ADJUSTING THE IDLE SPEED

IMPORTANT: Adjust the idle speed only:

¥If the idle speed becomes too high.

¥If the engine idle speed will not regulate (engine idles and speeds up again and again).

1.Turn auto-idle switch OFF. Start engine. Allow engine to warm up with no load for five minutes.

2.Remove engine linkage cover (Models 3WY46 and 3WY45 only).

3.Push plunger into solenoid body to manually engage solenoid and set idle speed.

4.Loosen the M8 nut that holds the solenoid mounting bracket to the generator (Models 3WY46 and 3WY45 only, See Figure 31). Do not loosen bolt that holds the solenoid mounting bracket to the generator on Model 3WY47, See Figure 32).
