CAUTION:
hot just after the engine is stopped. When replacing engine oil,
make sure that the engine main unit and engine oil are suffi-
ciently cooled down. Otherwise, there may remain a risk of scald.
Allow sufficient time after stopping engine for the engine oil to return
to the oil tank to ensure accurate reading of the oil level indicator.
If the oil filled above the limit, it may become
CAUTION:
dirty or may catch fire with white smoke.
Never discard replaced engine oil in garbage,

ground or sewage. Disposal of oil is regulated by law. In disposal,
always follow the relevant laws and regulations. For any points
remaining unknown, contact Authorized Service Agent.
Oil will deteriorate even when it is kept unused.

parts to a great extent. Be sure to check the period and quantity of
replacement.
