cleaning products, solvent or
thinner, fuel (gasoline), rust
removers or inhibitors, brake
fluid, antifreeze or electrolyte.
●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
Remove dirt with warm water, a mild
detergent, and a soft, clean sponge,
and then rinse thoroughly with clean
water. Use a toothbrush or bottle-
brush for hard-to-reach areas. Stub-
born 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
Since sea salt or salt sprayed on the
roads during winter are extremely
corrosive in combination with water,
carry out the following steps after
each ride in the rain, near the sea or
on salt-sprayed roads.
NOTE:
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.
ECA10790
CAUTION:
Do not use warm water since it
increases the corrosive action of
the salt.
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.
