Important Safety Instructions
DANGER: Carbon Monoxide. Using an engine indoors can kill
you in minutes. Engine exhaust contains high levels of carbon
monoxide (CO), a poisonous gas you cannot see or smell. You
may be breathing CO even if you do not smell engine exhaust.
WARNING: This product and its exhaust contain chemicals
known to the State of California to cause cancer, and birth
defects and other reproductive harm.
• NEVER use an engine inside homes, garages, crawlspaces 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 outdoors and far away from open windows, doors and
vents. These openings can pull in engine exhaust.
• Even when the engine is used correctly, CO may leak into your
home. ALWAYS use a battery-powered or battery backup CO
alarm in your house. Read and follow all directions for CO
alarm before using. If you feel sick, dizzy or weak at anytime,
move to fresh air immediately. See a doctor. You could have
carbon monoxide poisoning.
