WARMING UP ENGINE
1) After the engine starts, return the choke
knob to the half-way position. For
approximately the first 5 minutes after
starting, warm up the engine by operat-
ing at one fifth throttle or less. After the
engine has warmed up, completely push
in the choke knob. (Failure to do so will
shorten engine life.)
NOTE:
@
●
If the choke knob is left pulled out after
the engine starts, the engine will stall.
●
In temperatures of –5 °C or less, leave the
choke knob completely pulled out for
approximately 30 seconds after starting.
Then follow the standard instructions for
warming up the engine.

CHECKING POINTS AFTER
STARTING ENGINE
●
Check for a steady flow of water from the
cooling-water pilot hole.
●
Check that the low oil pressure warning
indicator light is off. (Refer to “WARNING
SYSTEM” section.)
●
After the engine has warmed up, check
that the engine idling speed is stable.
CAUTION:
@
If water is not flowing out of the pilot hole
at all times while the engine is running,
do not continue to run the engine. Over-
heating and serious damage could occur.
Stop the engine and check if the water
inlet on the lower casing is blocked. If the
problem cannot be found and corrected,
consult your Yamaha dealer.
