• The rated wattage of lights can be taken from light bulbs. The rated wattage of tools, appliances, and motors can be found on a data label or decal affixed to the device. • If the appliance, tool, or motor does not give wattage, multiply volts times ampere rating to determine watts (volts x amps = watts). • Some electric motors, such as induction types, require about three times more watts of power for starting than for running. This surge of power lasts only a few seconds when starting such motors.
1. Unplug all electrical loads from the unit's receptacles before starting engine. 2. Place generator on a level surface. 3. See Figure 3-2. Open the fuel shut-off valve (A). . ON OFF NOTE: If engine fires, but does not continue to run, move choke lever to Full Choke and repeat starting instructions. IMPORTANT NOTE: Do not overload the generator. Also, do not overload individual panel receptacles. These outlets are protected against overload with push-to-resettype circuit breakers.
