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 26).

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 (en- gine idles and speeds up again and again).

1. Turn Auto-Idle switch OFF. Start en-

gine. Allow engine to warm up with no

8.Turn Auto-Idle switch ON. Make sure solenoid is engaged. When engaged, the punger is pulled back into the solenoid.

9.If the engine speed is too slow, the en- gine will want to "hunt" or speed up and slow down repeatedly. When this occurs, increase engine speed by adjust- ing throttle stop screw on carburetor (refer to Carburetor Adjustment in Honda Engine Manual).

10.Replace the engine linkage cover (Models MGH4000CI, MGH5000DI, MGH5000DIE, MGH6000DI, and MGH7000DI).

AUTO-IDLE OPERATION

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

load for five minutes.

WARNING: Always set the idle speed before turning on the Auto- Idle. If idle speed is not set, the larger resistor on the control board may become hot. Heat from the resistor may damage the protec- tive coating on the control board.

1.If engine is cold, turn the Auto-Idle switch OFF (see Figure 26).

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 speci- fications outlined in owner's manual.

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

loosen bolt that holds the solenoid

mounting bracket to the generator on

Model MGH10000A (see Figure 28).

5. Slowly pull solenoid bracket away from

engine (on Model MGH10000A this will

require bending the bracket slightly).

6. With a volt meter, check the no-load

output voltage at the 120-volt duplex

receptacle. At proper idle speed (2680

minimum RPM) the meter should read

50-60 volts. Lower settings will cause

the Auto-Idle to not operate properly.

7. After reaching proper idle speed,

tighten M8 nut to secure solenoid
