Operation
TIP:
If the choke knob is left in the "
●
position while the engine is running, the en-
gine will run poorly or stall.
When the engine is cold, for example, when
●
the ambient temperature is low in winter, it
needs to be warmed up. For further infor-
mation, see page 58.
Do not turn the throttle grip unnecessarily to
●
open and close the throttle before starting
the engine, otherwise the engine may be
difficult to start. If the engine is difficult to
start, place the throttle grip in the
" " (warm engine) position and
try again.
Starting procedure (warm engine)
