cleaning products, solvent or

●Do not use high-pressure was-
hers or steam-jet cleaners sin-
ce they cause water seepage
and deterioration in the follo-
wing areas: seals (of wheel and
swingarm bearings, fork and
brakes), electric components
(couplers, connectors, instru-
ments, switches and lights),
breather hoses and vents.
●For scooters equipped with a
windshield: Do not use strong
cleaners or hard sponges as
they will cause dulling or scrat-
ching. Some cleaning com-
pounds for plastic may leave
scratches on the windshield.
Test the product on a small hid-
den part of the windshield to
make sure that it does not lea-
ve any marks. If the windshield
is scratched, use a quality
plastic polishing compound
after washing.
After normal use
1. Remove dirt with warm water, a
mild detergent, and a soft, clean
sponge, and then rinse tho-
roughly with clean water. Use a
toothbrush or bottlebrush for
hard-to-reach areas. Stubborn
dirt and insects will come off
more easily if the area is covered
with a wet cloth for a few minutes
before cleaning.
After riding in the rain, near the sea or
on salt-sprayed roads
1. Since sea salt or salt sprayed on
the roads during winter are extre-
mely corrosive in combination
with water, carry out the following
steps after each ride in the rain,
near the sea or on salt-sprayed
roads.
TIP
Salt sprayed on roads in the winter
may remain well into spring.
1. Clean the scooter with cold water
and a mild detergent after the
engine has cooled down. NOTI-
CE:Do not use warm watersince it increases the corrosive
action of the salt.
[ECA10791]
2. Apply a corrosion protection
spray on all metal, including
chrome- and nickel-plated, surfa-
ces to prevent corrosion.
After cleaning
1. Dry the scooter with a chamois or
an absorbing cloth.
2. Use a chrome polish to shine
chrome, aluminum and stainless-
steel parts, including the exhaust
system. (Even the thermally indu-
ced discoloring of stainless-steel
exhaust systems can be removed
through polishing.)
3. To prevent corrosion, it is recom-
mended to apply a corrosion pro-
tection spray on all metal, inclu-
ding chrome- and nickel-plated,
surfaces.
4. Use spray oil as a universal clea-
ner to remove any remaining dirt.
5. Touch up minor paint damage
caused by stones, etc.
6. Wax all painted surfaces.
7. Let the scooter dry completely
before storing or covering it.

3. Fill up the fuel tank and add fuel
stabilizer (if available) to prevent
the fuel tank from rusting and the
fuel from deteriorating.
4. Perform the following steps to
protect the cylinder, piston rings,
etc. from corrosion.
a. Remove the spark plug cap
and spark plug.
b. Pour a teaspoonful of engine
oil into the spark plug bore.
c. Install the spark plug cap
onto the spark plug, and then
place the spark plug on the
cylinder head so that the
electrodes are grounded.
(This will limit sparking during
the next step.)
d. Turn the engine over several
times with the starter. (This
will coat the cylinder wall with
oil.) WARNING! To prevent
damage or injury from spar-
king, make sure to ground
the spark plug electrodes
while turning the engine
over. e. Remove the spark plug cap
from the spark plug, and then
install the spark plug and the
spark plug cap.
5. Lubricate all control cables and
the pivoting points of all levers
and pedals as well as of the
sidestand/centerstand.
6. Check and, if necessary, correct
the tire air pressure, and then lift
the scooter so that both of its
wheels are off the ground. Alter-
natively, turn the wheels a little
every month in order to prevent
the tires from becoming degra-
ded in one spot.
7. Cover the muffler outlet with a
plastic bag to prevent moisture
from entering it.
8. Remove the battery and fully
charge it. Store it in a cool, dry
place and charge it once a
month. Do not store the battery in
an excessively cold or warm pla-
ce [less than 0 °C (30 °F) or more
than 30 °C (90 °F)]. For more
information on storing the bat-
tery, see page 6-19.TIP
Make any necessary repairs before
storing the scooter.
