ECA15192
Some models are equipped with
matte colored finished parts. Be
sure to consult a Yamaha dealer for
advice on what products to use be-
fore cleaning the vehicle. Using a
brush, harsh chemical products or
cleaning compounds when cleaning
these parts will scratch or damage
their surface. Wax also should not
be applied to any matte colored fin-ished parts.
EAU50832
Care While the open design of a scooter re-
veals the attractiveness of the technol-
ogy, it also makes it more vulnerable.
Rust and corrosion can develop even if
high-quality components are used. Fre-
quent and proper care does not only
comply with the terms of the warranty,
but it will also keep your scooter looking
good, extend its life and optimize its
performance.
Before cleaning1. Make sure that the seat is properly closed before cleaning.
2. Make sure that all caps and covers as well as all electrical couplers
and connectors, are tightly in-
stalled.
3. Remove extremely stubborn dirt, with a degreasing agent and a
brush, but never apply such prod-
ucts onto seals, gaskets and wheel
axles. Always rinse the dirt and de-
greaser off with water. Cleaning

water could splash on the bat-
tery or built-in charger. This
could cause an electric shock or
short circuit.

Do not wash the charging cord
and charging plug. Wipe cleanwith a dry rag.
NOTICE
ECA17122


cleaners, especially on spoked
wheels. If such products are
used on hard-to-remove dirt, do
not leave the cleaner on the af-
fected area any longer than in-
structed. Also, thoroughly rinse
the area off with water, immedi-
ately dry it, and then apply a cor-

sure the motor is cool before covering
the scooter.NOTICE
ECA17130

Storing the scooter in a poorly
ventilated room or covering it
with a tarp while it is still wet,
will allow water and humidity to
seep in and cause rust, power
unit failure, electric leakage, or
short-circuiting.

To prevent corrosion, avoid
damp cellars, stables (because
of the presence of ammonia)
and areas where strong chemi-cals are stored.
