tact with the surface of the drain hole. Then
tighten 1/4 to 1/2 turn more. Tighten the drain

CAUTION:
If the low oil pressure warning indicator
does not turn off or if there are oil leaks,
stop the engine and find the cause. Con-
tinued operation with a problem could
cause severe engine damage. Consult
your Yamaha dealer if the problem cannot
be located and corrected.
6. Turn off the engine and wait 3 minutes.
Recheck the oil level using the dipstick to
be sure the level falls between the upper
and lower marks. Fill with oil if it is below
the lower mark, or drain to the specified
level if it is above the upper mark.
