8Do not overfill the fuel tank. Fuel expands
when it heats up. If the fuel tank is over-
filled, fuel could spill out due to heat from
the engine or the sun.
8Be 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.
8Do not refuel right after the engine has
been running and is still very hot.
8Be sure the fuel tank cap is closed secure-
ly.

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.
w
8Improperly servicing or adjusting the car-
buretor could cause malfunction with the
possibility of an accident or the carburetor
could leak fuel, which would be a fire haz-
ard.
8Carburetor adjustments should only be
performed by a Yamaha dealer. Do not
attempt to perform these procedures
unless you have mechanical knowledge
and the necessary tools.
8Do not perform this procedure while the
engine is hot. Place a rag under the carbu-
retor to catch any fuel. Wipe up any spilled
fuel completely.
8After servicing the carburetor, always
check throttle operation before operating
the ATV to make sure it is working correct-
ly.

Troubleshooting
Although Yamaha machines receive a rigid
inspection before shipment from the factory,
trouble may occur during operation.
Any problem in the fuel, compression, or ignition
systems can cause poor starting and loss of
power. The troubleshooting chart describes a
quick, easy procedure for making checks. If
your machine requires any repair, take it to a
Yamaha dealer.
The skilled technicians at a Yamaha dealership
have the tools, experience, and know-how to
properly service your machine. Use only gen-
uine Yamaha parts on your machine. Imitation
parts may look like Yamaha parts, but they are
often inferior. Consequently, they have a short-
er service life and can lead to expensive repair
bills.
