Don't Overload Generator - Briggs & Stratton 030618 Operator's Manual

6. Start generator as described in the section Starting the Engine, then
place shelter over generator. Keep at least 1.5m (5 ft.) clearance on all
sides of generator including overhead with shelter in place.
WARNING Exhaust heat/gases could ignite combustibles, structures
or damage fuel tank causing a fire, resulting in death or
serious injury.
Contact with muffler area could cause burns resulting in
serious injury.
• DO NOT touch hot parts and AVOID hot exhaust gases.
• Allow equipment to cool before touching.
• Keep at least 1.5 m (5 ft.) of clearance on all sides of generator including
overhead.
• Remove shelter when temperatures are above 4°C [40°F].
7. Remove shelter when temperatures are above 4°C [40°F].
8. Turn engine OFF and let cool two (2) minutes before refueling. Let any
spilled fuel evaporate before starting engine.

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. This is the amount of
power your generator must produce to keep your items running. See
Wattage Reference Guide.
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.
Example:
Rated (Running)
Tool or Appliance
Window AC - 10,000 BTU
Deep Freezer
Television
Security System
Light (100 Watts)

Power Management
To prolong the life of your generator and attached devices, it is important to take
care when adding electrical loads to your 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
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.

NEVER add more loads than the generator capacity. Take special care to
consider surge loads in generator capacity, as described above.
