possible.
If the warning indicator and the warning light
do not go off, check the engine oil level in the
oil tank (see page 56 for engine oil level
checking procedures), and add engine oil if
necessary.
If the warning indicator and the warning light
still remain on, have a Yamaha dealer check
the snowmobile.
Oil pressure warning
The warning indicator comes on and “OP-LO”
(oil pressure low) appears in the odometer
display if the engine oil pressure is low when
the engine is started. At the same time, the
engine speed is limited to less than the clutch
engagement speed until the warning indicator
goes off.
If the engine oil pressure remains low for one
minute, the engine stops. If this occurs, have
a Yamaha dealer check the snowmobile.

If there is no engine oil in the oil passages
when the engine is started, such as after the
engine oil is changed, the warning indicator
