w8Do 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.

EBU00300Carburetor settings
In extremely cold weather, it is necessary to
change the carburetor settings to maintain opti-
mum engine performance and to prevent engine
damage.w8
Improperly servicing or adjusting the carbu-
retors could cause malfunction with the pos-
sibility of an accident or the carburetors
could leak fuel, which would be a fire hazard.
8
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.
8
Do not perform this procedure while the
engine is hot. Place a rag under each carbu-
retor to catch any fuel. Wipe up any spilled
fuel completely.
8
After servicing the carburetors, always check
throttle operation before operating the ATV
to make sure it is working correctly.

EBU00413Troubleshooting
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 Yama-
ha 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 shorter
service life and can lead to expensive repair
bills.
