SAFETY
The safety messages that follow have NOTICE
level hazards.
Any part which is found defective as a result of
inspection or any part whose measured value does
not satisfy the standard or limit must be replaced.

safety features such as defeating the engine speed
limit control or the diesel fuel injection quantity
control.
NEVER attempt to adjust the low or high idle speed
limit bolt. This may impair the safety and
performance of the engine and shorten its life.
Modifications of this type may void the warranty. If
adjustment is ever required, contact your
authorized Yanmar marine dealer or distributor.
Modifications may impair the engine's safety and
performance characteristics and shorten the

its warranty. Be sure to use Yanmar genuine
replacement parts.

other governmental agencies for the
proper disposal of hazardous materials
such as engine oil, diesel fuel and

2-6
NEVER dispose of hazardous materials by
dumping them into a sewer, on the ground or into
groundwater or waterways.
If any indicator illuminates during engine operation,
stop the engine immediately. Determine the cause
and repair the problem before continuing to operate
the engine.
Make sure the engine is installed on a level surface.
If a Yanmar Marine engine is installed at an angle
that exceeds the specifications stated in the
Yanmar Marine Installation Manuals, engine oil may
enter the combustion chamber causing excessive
engine speed, white exhaust smoke and serious
engine damage. This applies to engines that run
continuously or those that run for short periods of
time.
