6. Start the engine, and then let it idle
for several minutes while checking
it for oil leakage. If oil is leaking,
immediately turn the engine off and
check for the cause.
7. Turn the engine off, and then check
the oil level and correct it if neces-
sary. Final transmission oil
EAUT1561
Final transmission oilThe final transmission case must be
checked for oil leakage before each ride.
If any leakage is found, have a Yamaha
dealer check and repair the scooter. In
addition, the final transmission oil must
be changed as follows at the intervals
specified in the periodic maintenance
and lubrication chart.
1. Start the engine, warm it up by
riding the scooter for several min-
utes, and then stop the engine.
2. Place the scooter on the
centerstand.
3. Place an oil pan under the final
transmission case to collect the
used oil.

CoolantThe coolant level should be checked
before each ride. In addition, the cool-
ant must be changed at the intervals
specified in the periodic maintenance
and lubrication chart. Coolant
EAUT1523
To check the coolant level
The coolant level should be checked as
follows before each ride. In addition, the
coolant must be changed at the inter-
vals specified in the periodic mainte-
nance and lubrication chart.
1. Place the vehicle on the
centerstand.TIP
8The coolant level must be checked
on a cold engine since the level
varies with engine temperature.
8Make sure that the vehicle is posi-
tioned straight up when checking
the coolant level. A slight tilt to the
side can result in a false reading.
2. Check the coolant level in the cool-
ant reservoir.TIP
The coolant should be between the mini-
mum and maximum level marks.ZAUM00**
