WARNING
Avoid Carbon Monoxide Poisoning
All engine exhaust contains carbon monoxide,
a deadly gas. Breathing carbon monoxide can
cause headaches, dizziness, drowsiness, nausea, confusion, and eventually death.
Carbon Monoxide is a colorless, odorless,
tasteless gas which may be present even if you
do not see or smell any engine exhaust. Deadly
levels of carbon monoxide can collect rapidly
and you can quickly be overcome and unable
to save yours elf. Als o , de ad l y le ve ls of ca rbo n
monoxide can linger for hours or days in en-
2-3
closed or poorly ventilated areas. If you experience any symptoms of carbon monoxide
poisoning, leave the area immediately, get
fresh air, and SEEK MEDICAL TREATMENT.
● Do not run engine indoors. Even if you try to
ventilate engine exhaust with fans or open
windows and doors, carbon monoxide can
rapidly reach dangerous levels.
● Do not run engine in poorly ventilated or par-
tially enclosed areas such as barns, garages,
or carports.
● Do not run engine outdoors where engine
exhaust can be drawn into a building
through openings such as windows and
doors.

WARNING
When transporting the ATV in another vehicle,
be sure it is kept upright and that the fuel cock
is in the “OFF” position. Otherwise, fuel may
