GENERATOR CAPACITY

NOTICE

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.

Make sure the generator can supply enough continuous 

(running) and surge (starting) watts for the items you will 

power at the same time. 
The total power requirements (Volts x Amps = Watts) of all 

appliances connected must be considered. Appliance and 

power tool manufacturers usually list rating information 

near the model or serial number.
To determine power requirements:

1. 

Select the items you will power at the same time.

2. 

Total the continuous (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 on the next page.

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, 

use 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 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.
