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 recommended 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
EBU32730CleaningFrequent, 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 pipe to 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 out the linings. Wet brakes may have reduced stopping
ability, increasing the chance of an ac-
cident.
[EWB03470]

NOTICE: Excessive wa-
ter pressure 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,
lift the left side of the tailgate and pull the tail-
gate to the left. 4. Once the majority of the dirt has been hosed off, wash all surfaces with warm
water and mild, detergent-type soap. An
old toothbrush or bottle brush is handy
for hard-to-get-at places.

5. Rinse the vehicle off immediately withclean water and dry all surfaces with a
clean chamois towel or soft, absorbent
cloth.
6. Clean the seats with a vinyl upholstery
cleaner to keep the covers pliable and
glossy.
7. Automotive-type wax may be applied to
all painted and chrome-plated surfaces.
Avoid combination cleaner-waxes. Many
contain abrasives which may scratch the
paint or protective finish. When finished,
start the engine and let it idle for several
minutes.EBU32740StorageLong term storage (60 days or more) of your
vehicle will require some preventive proce-
dures to guard against deterioration. Make
any necessary repairs before storing the vehi-
cle. After thoroughly cleaning the vehicle, prepare
for storage as follows:
1. Fill the fuel tank with fresh fuel and add the specified amount of Yamaha Fuel
Stabilizer and Conditioner or equivalent
product. Operate the vehicle for at least 5
minutes to distribute treated fuel through
the fuel system.
2. Remove the spark plug, pour about one tablespoon of SAE 10W-40 or 20W-50
motor oil in the spark plug hole and install
the spark plug. Ground the spark plug
wire and turn the engine over several
times to coat the cylinder wall with oil.
3. Lubricate all control cables.
4. Block up the frame to raise all wheels off the ground.
Specified amount:1 oz of stabilizer to each gallon of fuel (or
7.5 ml of stabilizer to each liter of fuel)
