Step 1.
Ensure all electrical loads are removed from the generator.
Disconnect all the extension cords and ensure the main breaker
is in the OFF position. Remove all flammable materials and
debris from the area. Make sure the generator is level.
Step 2.
Check the oil level by removing the oil fill cap.
 Put the generator on a level surface with the engine
stopped.
 Remove the oil filler cap.
 Check the oil level. If the oil level is low, fill it until the oil is
overflowing. It will take approximately 1.1 - 1.5 quarts of
oil.
If additional oil is need, SAE 10W-30 engine oil is recommended
for most general purpose applications. In cold weather climate,
use SAE 5W-30.
Step 3.
Make sure there is fuel in the gasoline
tank. Look at the fuel level indicated
by removing the fuel cap to inspect
the contents of the fuel tank. The fuel
filter can also be inspected once the
fuel cap is removed. Ensure the fuel filter is clean of dirt and
debris. Tightly secure the fuel cap after your inspection is com-
plete.
Fuel can damage paint and plastic. Be careful not to spill fuel
when filling your fuel tank. Damage caused by spilling fuel is not
covered under warranty. Use unleaded gasoline with a pump
octane rating of 86 or higher. This engine is certified to operate
on unleaded gasoline. Unleaded gasoline produces fewer en-
gine and spark plug deposits and
extends exhaust system life. Never
use stale or contaminated gasoline
or an oil/gasoline mixture. Avoid
getting dirt or water in the fuel tank.
CARBON MONOXIDE GAS
CARBON MONOXIDE Using a generator indoors CAN KILL
YOU IN MINUTES.
Generator exhaust contains carbon monoxide (CO). This is
a poison you cannot see or smell. If you can smell the gen-
erator exhaust, you are breathing CO. But even if you can-
not smell the exhaust, you could be breathing CO.
NEVER use a generator inside homes, garages, crawl-
spaces, or other partly enclosed areas. Deadly levels of
carbon monoxide can build up in these areas. Using a fan
or opening windows and doors does NOT supply enough
fresh air.
ONLY use a generator outside and far away from windows,
doors, and vents. These openings can pull in generator
exhaust.
Even when you use a generator correctly, CO may leak into
the home. ALWAYS use a battery-powered or battery-
backup CO alarm in the home.
If you start to feel sick, dizzy, or weak after the generator
has been running, move to fresh air RIGHT AWAY. See a
doctor. You could have carbon monoxide poison.”
DANGER
Operating the Generator
DO NOT overfill the tank. Leave a 1 inch air gap in the tank.
Gasoline is highly flammable and explosive. You can be
burned or seriously injured when refueling.
 Stop engine and keep heat, sparks, and flame away.
 Refuel only outdoors.
 Wipe up spills immediately.
WARNING
Ethanol warning
This portable generator is not for use with
gasoline/ethanol blends with over 15%
ethanol.
For power outages, permanently installed stationary generators
are better suited for providing backup power to the home. Even a
properly connected portable generator can become overloaded.
This may result in overheating or stressing the generator compo-
nents, possibly leading to a generator failure.
