Electric Generators

Operation (Continued)

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 protective coating on the control board.

5.Slowly pull solenoid bracket away from engine (on Model 3WY47 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 mounting bracket (Models 3WY46 and 3WY45 only).

8.Turn auto-idle switch ON. Make sure solenoid is engaged. When engaged, the plunger is pulled back into the solenoid.

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

10.Replace the engine linkage cover (Models 3WY46 and 3WY45 only).

HIGH ALTITUDE OPERATION

This generator will not perform well at high altitudes without proper adjustment. See engine ownerÕs manual for details.

ADDING ELECTRICAL LOADS

IMPORTANT: Do not overload generator. Make sure total wattage of all electrical loads does not exceed rated wattage of generator. Overloading may shorten generator life. It could also cause internal damage to generator. Overloading

will trip circuit breaker.

IMPORTANT: Keep full power selector switch in the 120 VOLT ONLY position if only powering 120V items. Only move switch to 120/240 VOLT position if powering 240V items.

1.Check items to be powered. Their nameplate lists their wattage ratings.

NOTE: The wattage ratings for some electrical motors are misleading. They may require 3 to 6 times their rated wattage to start. You must figure total electrical load wattage. Make sure total wattage of all electrical loads does not exceed rated wattage of generator. See ÒDetermining Electrical Load for Generator,Ó page 11.

2.Start engine. Let engine reach full speed.

3.Connect electrical loads one at a time. If the load consists of electric motors, start them first. Always start the largest first. Start each motor individually.

DISCONNECTING ELECTRIC LOADS

Remove electrical loads one at a time. Remove voltage sensitive items first. Voltage sensitive items include TVs, VCRs, and other home electronic items.

STOPPING ENGINE

IMPORTANT: The engine speed is preset. The throttle is locked in preset position. Do not adjust throttle.

Follow the steps below to stop engine.

1.Remove all electrical loads from generator (See ÒDisconnecting Electrical Loads,Ó above). Remove electrical loads one at a time.

2.Let engine run for two or three minutes after removing electrical loads. This lets engine cool slightly.

3.Turn engine switch to the OFF position (See Figures 33 and 34).
