POISONOUS GAS HAZARD. Engine exhaust contains carbon
monoxide, a poisonous gas that could kill you in minutes. You
CANNOT see it, smell it, or taste it. Even if you do not smell exhaust
fumes, you could still be exposed to carbon monoxide gas. If you start
to feel sick, dizzy, or weak while using this product, shut it off and get
to fresh air RIGHT AWAY.See a doctor. You may have carbon
monoxide poisoning.
WARNING
Operate this product ONLY outside far away from windows, doors and vents to
reduce therisk of carbonmonoxide gas fromaccumulating and potentiallybeing
drawn towards occupied spaces.
Install battery--operated carbon monoxide alarms or plug--in carbon monoxide
alarms with battery back-up according to the manufacturer’s instructions.
Smoke alarms cannot detect carbon monoxide gas.
DO NOT run this product inside homes, garages, basements, crawlspaces,
sheds, or other partially-enclosed spaces even if using fans or opening doors
and windows for ventilation. Carbon monoxide can quickly build up in these
spaces and can linger for hours, even after this product has shut off.
ALWAYS place this product downwind and point the engine exhaust away from
occupied spaces.
