gine or the sun.

Be careful not to spill fuel, especially on the
engine or exhaust pipe which can cause a
fire and severe injury. Wipe up any spilled
fuel immediately.

Do not refuel right after the engine has been
running and is still very hot.

Be sure the fuel tank cap is closed securely.

Changing the carburetor settings
In extremely cold weather, it is necessary to
change the carburetor settings to maintain opti-
mum engine performance and to prevent engine
damage.
WARNING

EWB02000

Improperly servicing or adjusting the carbu-
retor could cause it to malfunction with the
possibility of an accident, or the carburetor
could leak fuel, which would be a fire hazard.

Carburetor adjustments should only be per-
formed by a Yamaha dealer. Do not attempt
to perform these procedures unless you
have mechanical knowledge and the neces-
sary tools.

Do not perform this procedure while the en-
gine is hot. Place a rag under the carburetor
to catch any fuel. Wipe up any spilled fuel
completely.

After servicing the carburetor, always check
the throttle lever operation before operating
the ATV to make sure it is working correctly.
