EBU26931Oil temperature warning light“” 
This warning light comes on when the engine over-

as it is safe to do so, and allow it to cool.
The electrical circuit of the warning light can be
checked by turning the key to “ON”, with the engine
stop switch set to“”, and then pushing the start
switch.
If the warning light does not come on while the start
switch is being pushed, then go off after the start
switch is released, have a Yamaha dealer check
the electrical circuit.
If the warning light stays on, allow the engine to
cool. If the warning light stays on when the engine
is cool, have a Yamaha dealer check the electrical
circuit.NOTICEECB00010The engine may overheat if the ATV is over-
loaded. In this case, reduce the load to spec-
ification.Start the engine after making sure that the
warning light is out. Continuous use while
the warning light is on may cause damage to
the engine.

nition such as the pilot lights of water heaters
and clothes dryers.
2. Do not overfill the fuel tank. When refueling,
be sure to insert the pump nozzle into the fuel
tank filler hole. Stop filling when the fuel reach-
es the bottom of the filler tube. Because fuel
expands when it heats up, heat from the en-
gine or the sun can cause fuel to spill out of
the fuel tank.
3. Wipe up any spilled fuel immediately.
NOTICE: Immediately wipe off spilled fuel
with a clean, dry, soft cloth, since fuel may
deteriorate painted surfaces or plastic
parts.
 [ECB00981]
4. Turn the fuel tank cap fully clockwise to make
sure it is securely closed.

EBU25720Troubleshooting Although Yamaha ATVs receive a thorough in-
spection before shipment from the factory, trouble
may occur during operation. Any problem in the fu-
el, compression, or ignition systems, for example,
can cause poor starting and loss of power.
The following troubleshooting chart represents a
quick and easy procedure for checking these vital
systems yourself. However, should your ATV re-
quire any repair, take it to a Yamaha dealer, whose
skilled technicians have the necessary tools, expe-
rience, and know-how to service the ATV properly.
Use only genuine Yamaha replacement parts. Im-
itation parts may look like Yamaha parts, but they
are often inferior, have a shorter service life and
can lead to expensive repair bills.
WARNING
EWB02280Do not smoke when checking the fuel system.
Fuel can ignite or explode, causing severe inju-
ry or property damage. Make sure there are no
open flames or sparks in the area, including pi-
lot lights from water heaters or furnaces.U1AB60E0.book  Page 46  Wednesday, April 29, 2009  10:19 AM
