Operation
Generator Capacity
To make sure your generator can supply enough running
watts and starting watts for the items you will power at the
same time, follow these three simple steps:
1 . Select the items you will power at the same time . See
following list for typical wattages .
Tool or Appliance
Light Bulb - 75 Watt
Sump Pump - 1/3 HP
Refrigerator/Freezer
Water Well Pump - 1/3 HP
Window AC - 10,000 BTU
Furnace Fan Blower - 1/2 HP
Microwave Oven - 1000 Watt
Plasma Television - 50"
Laptop
Garage Door Opener - 1/2 HP
* Typical wattages listed are approximate only . Check tool
or appliance for actual wattage .
** The momentary electrical current the generator can
provide to start electric motors, per Briggs & Stratton
standard 628K . It does not represent the power required
to continuously run electrical loads . It is the maximum
current that can momentarily be supplied when starting a
motor, multiplied by the generator's rated voltage .
2 . Total the running watts . This is the amount of power
your generator must produce to keep your items
running . See following example:
Example
Tool or Appliance
Window AC - 10000 BTU
Refrigerator/Freezer
Plasma Television
Light (75 Watts)
Total running watts
Highest starting watts
Total generator watts required
3 . Estimate the starting watts you will need . Because
not all motors start at the same time, total starting
wattage can be estimated by adding only the item
with the highest additional starting watts requirements
to the total running watts from step 2 .

Power Management
To manage generator power, sequentially add loads as
follows:
1 . With nothing connected to generator, start the engine
outdoors .
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 starting watts in generator
capacity .

CO Detection

Carbon Monoxide (CO) Shutdown System
CO Detection automatically shuts down the engine when
harmful levels of carbon monoxide accumulate around the
generator or a CO Detection fault occurs . After shutdown,
the CO Detection indicator light will blink for at least five
minutes per the chart below .
CO Detection DOES NOT replace carbon monoxide alarms .
Install battery-powered carbon monoxide alarm(s) in your
home . Don't run generator in enclosed areas .

Blue light will blink for five seconds at the startup of generator to
¥
show CO Detection functioning properly .
Step 5: Generator Shutdown
1 . Turn off and unplug all electrical loads from generator
panel receptacles . Never stop engine with electrical
devices plugged in and turned on .
2 . Let engine run at no-load for one minute to stabilize
internal temperatures of engine and generator .
3 . Push on/off switch to off (0) position .
4 . Move fuel valve to off (0) position .
Description
Carbon monoxide accumulated around
generator . Move generator to an open,
outdoor area 20 ft . (6 .1 m) from
occupied spaces with exhaust pointed
away . Automatic shutoff is an indication
generator was improperly located .
If you start to feel sick, dizzy, weak,
or your homes carbon monoxide alarm
sounds while using this product, get
to fresh air right away . Call emergency
services . You may have carbon monoxide
poisoning .
