Don't Overload Generator
Capacity
You must make sure your generator cansupply enough
rated (running) and surge (starting) watts for the items you
will power at the same time. Follow these simple steps:
1. Selectthe itemsyou will power at the same time.
2. Total the rated(running) watts of these items. This is
the amount of power your generator must produce to
keepyour items running. Seethe table on the right.
3. Estimatehow many surge (starting) watts you will need.
Surge wattageis the short burst of power neededto
start electric motor-driven tools or appliancessuch asa
circular saw or refrigerator. Becausenot all motors start
atthe sametime, total surge watts can be estimatedby
adding only the item(s) with the highest additional surge
watts to the total ratedwatts from step 2.

Power Management
To prolong the life of your generatorand attacheddevices, it
is important to take carewhen adding electrical loadsto your
generator. Thereshould be nothing connectedto the
generator outlets before starting its engine.The correct and
safe way to manage generator power isto sequentiallyadd
loads asfollows:
1. With nothing connected to the generator,start the
engine asdescribed in this manual.
2. Plug in andturn on the first load, preferablythe largest
load you have.
3. Permit the generatoroutput to stabilize (engine runs
smoothly and attached deviceoperates properly).
4. Plug in andturn on the next load.
5. Again, permit the generatorto stabilize.
6. Repeatsteps 4 and 5 for eachadditional load.
