DON'T OVERLOAD GENERATOR

CAPACITY

Make sure the generator can supply enough rated (running) and surge (starting) watts for the items you will power at the same time. Follow these simple steps:

1.Select the items you will power at the same time.

2.Total the rated (running) watts of these items. This is the amount of power the generator must produce to keep the items running. See the wattage reference chart at the right.

3.Estimate how many surge (starting) watts you will need. Surge wattage is the short burst of power needed to start electric motor-driven tools or appliances such as a circular saw or refrigerator. Because not all motors start at the same time, total surge watts can be estimated by adding only the item(s) with the highest additional surge watts to the total rated watts from step 2.

Example:

Tool or Appliance	Rated (Running)			Surge
	Watts		(Starting) Watts
Window Air	1200			1800
Conditioner
Refrigerator	800			1600
Deep Freezer	500			500
Television	500			−
Light (75 Watts)	75			−
	3075 Total		1800 Highest
	Running Watts			Surge Watts
				Maximum
Total Rated (Running Watts)		= 3075		Allowed
				5800
Highest Additional Surge Watts		= 1800
Total Generator Output Required		= 4875		6200

POWER MANAGEMENT

To prolong the life of the generator and attached devices, it is important to take care when adding electrical loads to the generator. There should be nothing connected

to the generator outlets before starting the engine. The correct and safe way to manage generator power is to sequentially add loads as follows:

1.With nothing connected to the generator, start the engine as described earlier in this manual.

2.Plug in and turn on the first load, preferably the largest load you have.

3.Permit the generator output to stabilize. (engine runs smoothly and attached device operates properly.)

4.Plug in and turn on the next load.

5.Again, permit the generator to stabilize.

6.Repeat steps 4 and 5 for each additional load.

Never add more loads than the generator capacity. Take special care to consider surge loads in generator capacity as previously described.

WARNING:

Do not overload generator's capacity. Exceeding generator's wattage/amperage capacity can damage generator and/or electrical devices connected to it.
