Engine oil is extremely hot immediately af-
ter the engine is turned off. Coming in con-
tact with or getting any engine oil on your
clothes could result in burns.
ECJ00992
Do not run the engine with too much or not
enough oil in the engine, otherwise the en-

It is recommended to have a Yamaha dealer
change the engine oil and the engine oil filter.
However, if you choose to change the oil and
filter on your own, consult a Yamaha dealer.
