NOTE:
The radiator fan is automatically
switched on or off according to the
coolant temperature in the radiator. If
the engine overheats, see page 6-40
for further instructions.
Cleaning the air filter element
1.Place the scooter on the center-
stand.
2.Remove the air filter case cover
by removing the screws.
3.Pull the sponge material out
along with the mesh sheet, clean
it with solvent, and then squeeze
the remaining solvent out.

Air filter and V-belt case air
filter elementsThe air filter and V-belt case air filter
elements should be cleaned at the
intervals specified in the periodic
maintenance and lubrication chart.
Clean both filter elements more fre-
quently if you are riding in unusually
wet or dusty areas.
EC000092
cC8Make sure that each filter ele-
ment is properly seated in its
case.
8The engine should never be
operated without the filter ele-
ments installed, otherwise the
piston(s) and/or cylinder(s)
may become excessively
worn.

2.Remove the blown fuse, and
then install a new fuse of the
specified amperage.
EC000103
cCDo not use a fuse of a higher
amperage rating than recommend-
ed to avoid causing extensive
damage to the electrical system
and possibly a fire.3.Turn the key to ÒONÓ and turn on
the electrical circuit in question to
check if the device operates.

EW000070
w8Do not remove the radiator cap when the engine and radiator are hot. Scalding hot fluid and steam may be
blown out under pressure, which could cause serious injury. Be sure to wait until the engine has cooled.
8After removing the radiator cap retaining bolt, place a thick rag, like a towel, over the radiator cap, and then
slowly rotate the cap counterclockwise to the detent to allow any residual pressure to escape. When the
hissing sound has stopped, press down on the cap while turning it counterclockwise, and then remove the
cap.Wait until the 
engine has cooled.
Check the coolant level in the 
reservoir and radiator.
The coolant level 
is OK.The coolant level is low.
Check the cooling system
for leakage.
Have a Yamaha dealer checkand repair the cooling system.Add coolant. (See NOTE.)
Start the engine. If the engine overheats again, 
have a 
Yamaha dealer check 
and repair the cooling system.
There is
leakage.
There is 
no leakage.
NOTE:
If coolant is not available, tap water can be temporarily used instead, provided that it is changed to the recommended
coolant as soon as possible.
