10. Remove the oil dipstick and wipe it
clean.
11. Insert the dipstick and remove it again.
Be sure to completely insert the dipstick
into the dipstick guide, otherwise the oil
level measurement will be incorrect.
12. Recheck the oil level using the dipstick to
be sure the level falls between the upper
and lower marks. Consult your Yamaha
dealer if the oil level is out of specified
level.
13. Start the engine and make sure that the
low oil pressure-alert indicator remains
off. Also, make sure that there are no oil
leaks. NOTICE: If the low oil pressure-
alert indicator comes on or if there are
oil leaks, stop the engine and find the
cause. Continued operation with a
problem could cause severe engine
damage. Consult your Yamaha dealer
if the problem cannot be located and
corrected.
