WARNING
EWB03420Batteries may produce explosive gases.
Ventilate when charging or using in a
closed space. Keep batteries away from
sparks, flames, cigarettes, or other sourc-
es of ignition. To remove the battery1. Turn the key to “ ” (off).
2. Remove the hood. (See page 8-10 for hood removal and installation proce-
dures.)
3. Remove the air intake duct panel by re-
moving the quick fastener screws. 4. Unhook the battery bands.
5. Disconnect the negative battery lead first,
then the positive battery lead by remov-
ing their bolt. NOTICE: When removing
the battery, the main switch must be

To install the batteryTIPBe sure the battery is fully charged. 1. Place the battery in its compartment.
2. Connect the positive battery lead first,then the negative battery lead by install-
ing their bolt. NOTICE: When installing
the battery, the main switch must be
off, and the positive lead must be con-
nected before the negative lead.
[ECB01111]
3. Hook the battery bands.
4. Install the air intake duct panel by install- ing the quick fastener screws.
5. Install the hood.EBU32650Jump-startingJump-starting the vehicle should be avoided.
The battery should be removed and charged
instead.
WARNING
EWB03430To avoid battery explosion and/or serious
damage to the electrical system:
 Do not connect the negative lead of the
jumper cable to the negative terminal of
the battery.
 Do not touch the positive lead of the
jumper cable to the negative lead.
 Do not reverse the polarity of the jumper
cables when connecting to the batteries. However, if the vehicle must be jump-started,
proceed as follows.
1. Positive battery lead (red)
2. Battery band
3. Negative battery lead (black)

If a fuse is blown, replace it as follows.1. Turn the key to “ ” (off) and turn off the
electrical circuit in question.
NOTICEECB00641To prevent accidental short-circuiting,
turn off the main switch when checking or
replacing a fuse. 2. Remove the hood. (See page 8-10 forhood removal and installation proce-
dures.)
3. Remove the blown fuse, and then install a new fuse of the specified amperage.
WARNING! Always use a fuse of the specified amperage. Never use any
material in place of the proper fuse.
Using an improper fuse can cause
damage to the electrical system and
may lead to a fire.

4. Install the bulb holder (together with thebulb) by turning it clockwise.EBU32700TroubleshootingAlthough Yamaha vehicles receive an inspec-
tion 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 vehicle
requires any repair, take it to a Yamaha deal-
er.
The skilled technicians at a Yamaha dealer-
ship have the tools, experience, and know-
how to properly service your vehicle. Use only
genuine Yamaha parts on your vehicle. Imita-
tion parts may look like Yamaha parts, but
they are often inferior. Consequently, they
have a shorter service life and can lead to ex-
pensive repair bills.
WARNING
EWB03450When checking the fuel system, do not
smoke and make sure there are no open
flames or sparks in the area, including pilot
lights from water heaters or furnaces.
Gasoline or gasoline vapors can ignite or
explode, causing severe injury or property
damage.

Engine overheating
Wait for the engine to cool before removing the radiator cap. WARNING! If the engine is not
cool when removing the radiator cap, hot fluid and steam could blow out under pressure
and burn you.
[EWB03460]
Place a thick rag over the cap and remove the cap slowly to allow any re-
maining pressure to escape.
TIPIf it is difficult to get the recommended coolant, tap water can be used temporarily, provided that
it is changed to the recommende d coolant as soon as possible. Wait until the
engine has cooled.
Check the coolant level in the
coolant reservoir and/or radiator.
Level is OK.Level is low, check the
cooling system for leakage.
No
leakage.Leakage.
Ask a Yamaha dealer to inspect
and repair the cooling system.Add coolant. (See TIP.)
Restart the engine. If the engine overheats again, ask a
Yamaha dealer to inspect and/or repair the cooling system.

CLEANING AND STORAGE
EBU33681CleaningFrequent, thorough cleaning of your vehicle
will not only enhance its appearance but will
improve its general performance and extend
the useful life of many components.1. Before cleaning the vehicle: a. Block off the end of the exhaust pipeto prevent water entry. A plastic bag
and strong rubber band may be used.
b. Make sure the spark plug and all filler caps are properly installed.
2. If the engine case is excessively greasy, apply degreaser with a paint brush. Do
not apply degreaser to the wheel axles.
3. Rinse the dirt and degreaser off with a garden hose. Use only enough pressure
to do the job. WARNING! Test the
brakes after washing. Apply the
brakes several times at slow speeds to
let friction dry the brakes. Wet brakes may have reduced stopping ability, in-
creasing the chance of an accident.
[EWB03471]

NOTICE: Excessive water pres-
sure may cause water seepage and
deterioration of wheel bearings,
brakes, transmission seals and electri-
cal devices. Many expensive repair
bills have resulted from improper high-
pressure detergent applications such
as those available in coin-operated car
washers.
[ECB00712]
TIPThe tailgate can be removed to make it easier
to clean the cargo bed. To separate the tail-
gate from the cargo bed, unhook the latches,
and then pull up the tailgate. (See page 4-21
for tailgate removal and installation proce-
dures.)

EBU33221For Europe only
The figures quoted are emission levels and
are not necessarily safe working levels. Whilst
there is a correlation between the emission
and exposure levels, this cannot be used reli-
ably to determine whether or not further pre-
cautions are required. Factors that influence
the actual level of exposure of work-force in-
clude the characteristics of the work room,
the other sources of noise, etc. i.e. the num-
ber of machines and other adjacent process-
es, and the length of time for which an
operator is exposed to the noise. Also the
permissible exposure level can vary from
country. This information, however, will en-
able the user of the machine to make a better
evaluation of the hazard and risk.
