EAU15593
The condition of a vehicle is the owner’s responsibility. Vital components can start to deteriorate quickly and unexpec-
tedly, even if the vehicle remains unused (for example, as a result of exposure to the elements). Any damage, fluid lea-
kage or loss of tire air pressure could have serious consequences. Therefore, it is very important, in addition to a tho-
rough visual inspection, to check the following points before each ride.
NOTE:
Pre-operation checks should be made each time the vehicle is used. Such an inspection can be accomplished in a very
short time; and the added safety it assures is more than worth the time involved.

Tires
To maximize the performance, durabi-
lity, and safe operation of your vehi-
cle, note the following points regar-
ding the specified tires.
Tire air pressure
The tire air pressure should be chec-
ked and, if necessary, adjusted befo-
re each ride.
EWA10500
s s
WARNING
●The tire air pressure must be
checked and adjusted on cold
tires (i.e., when the temperatu-
re of the tires equals the
ambient temperature).
●The tire air pressure must be
adjusted in accordance with
the riding speed and with the
total weight of rider, passenger,
cargo, and accessories appro-
ved for this model.EWA11200
s s
WARNING
Because loading has an enormous
impact on the handling, braking,
performance and safety characte-
ristics of your vehicle, you should
keep the following precautions in
mind.
●NEVER OVERLOAD THE VEHI-
CLE! Operation of an overloa-
ded vehicle may result in tire
damage, loss of control, or
severe injury. Make sure that
the total weight of rider, pas-
senger, cargo, and accessories
does not exceed the specified
maximum load for the vehicle.
●Do not carry along loosely pac-
ked items, which can shift
during a ride.
●Securely pack the heaviest
items close to the center of the
vehicle and distribute the
weight evenly on both sides.
●Adjust the tire air pressure with
regard to the load.
●Check the tire condition and air
pressure before each ride.
Tire air pressure (measured on
cold tires):
0~90 kg (0~198 lb):
Front:
175 kPa (25 psi) (1.75 kgf/cm
2)
Rear:
200 kPa (28 psi) (2.00 kgf/cm
2)
CS50/CS50M 90~169 kg
(198~373 lb)
CS50Z 90~166 kg (198~366 lb):
Front:
175 kPa (25 psi) (1.75 kgf/cm
2)
Rear:
225 kPa (32 psi) (2.25 kgf/cm

Maximum load*:
CS50/CS50M 169 kg (373 lb)
CS50Z 166 kg (366 lb)

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.)
e. Remove the spark plug cap from
the spark plug, and then install
the spark plug and the spark plug
cap.EWA10950
s s
WARNING
To prevent damage or injury from
sparking, make sure to ground the
spark plug electrodes while turning
the engine over.
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 ºC (30 ºF) or more
than 30 ºC (90 ºF)]. For moreinformation on storing the bat-
tery, see page 6-19.
NOTE:
Make any necessary repairs before
storing the scooter.
