NOTE:
It is strongly recommended that Polaris Carbon
Clean be added regularly as directed to the fuel systems
of all Polaris ATVs. Carbon Clean stabilizes the fuel,
preventing clogging of the small passages and orifices
common to ATV carburetors, and ensures constant
performance, reliability and easier starting.

WARNING
Gasoline is extremely flammable and explosive
under certain conditions.
Always stop the engine and refuel outdoors
or in a well ventilated area.
Do not overfill the tank. The tank is at full
capacity when the fuel reaches the bottom of
the filler neck. Leave room for expansion of
fuel.
Never start the engine or let it run in an
enclosed area. Gasoline powered engine
exhaust fumes are poisonous and can cause
loss of consciousness and death in a short
time.
Never drain the float bowl when the engine is
hot. Severe burns may result.
Do not smoke or allow open flames or sparks
in or near the area where refueling is
performed or where gasoline is stored.
If you get gasoline in your eyes or if you
should swallow gasoline, seek medical
attention immediately.
If you spill gasoline on your skin or clothing,
immediately wash with soap and water and
change clothing.
