ELECTRICAL

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.

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 its 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 later in this manual.

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

load you have.

*Wattages listed are approximate. Check tool or equipment for actual wattage.

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.

CAUTION:

Do not overload the generator’s capacity. Exceeding

the generator’s wattage/amperage capacity can

damage the generator and/or electrical devices

connected to it.
