 WARNING 

Batteries can emit explosive gases. To reduce the possibility of personal injury, always ventilate the compartment before servicing the batteries. To reduce the possibility of arcing, remove the negative (-) battery cable first and attach the negative (-) battery cable last.
 WARNING 

To reduce the possibility of personal injury, avoid direct contact of hot oil with your skin.
 WARNING 

Some state and federal agencies have determined that used engine oil can be carcinogenic and cause reproductive toxicity. Avoid inhalation of vapors, ingestion, and prolonged contact with used engine oil. If not reused, dispose of in accordance with local environmental regulations.
 CAUTION 

Use caution when draining oil or replacing filters that oil is not spilled or drained into the bilge area. The oil and oil filters must be discarded in accordance with local environmental regulations.

NOTE: The engines use a variety of combinations of gaskets and/or RTV for sealing. When installing the oil pan, use the same combinations of gasket and/or RTV that were on the pan.
