SAFETY
Yanmar is concerned for your safety and the
condition of your marine engine. Safety statements
are one of the primary ways to call your attention to
the potential hazards associated with Yanmar
marine engines. Follow the precautions listed
throughout the manual before operation, during
operation and during periodic maintenance
procedures for your safety, the safety of others and
to protect the performance of your marine engine.
Keep the labels from becoming dirty or torn and
replace them if they are lost or damaged. Also, if
you need to replace a part that has a label attached
to it, make sure you order the new part and label at
the same time.
