Snowmobile engines discharge fuel and exhaust which
contain chemicals known to the State of California to
cause cancer and birth defects or other reproductive
harm onto the snow on which they operate. Keep this
engine properly tuned and avoid unnecessary idling
and spillage during fueling.
Do not smoke or allow open flames or sparks in or near
the area where refueling is performed, gasoline is
stored, or gasoline is used.

If you get gasoline in your eyes or if you swallow
gasoline, see your doctor immediately.
Never start the engine or let it run in an enclosed area.
