DON'T OVERLOAD

GENERATOR

Capacity

You must make sure your 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. See Figure 6.

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.Total surge watts is estimated by adding only the one item with the highest additional surge watts to the total rated watts from step 2.

For Example:

Tool or Appliance	Rated (Running)		Additional Surge
	Watts		(Starting) Watts
Refrigerator	800		1600
Deep Freezer	500		500
Television	500		-
Light (75 Watts)	75		-
	1875 Total Running		1600 Highest Surge
	Watts		Watts
Total Rated (Running) Watts		= 1875
Highest Additional Surge Watts		= 1600
Total Generator Output Required		= 3475

Power Management

It is important to take care when adding electrical loads to your generator.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 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.

OPERATION

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 generator capacity.Take special care to consider surge loads in generator capacity, as described above.
