CAUTION
Observe the following
environmental operating
conditions to maintain engine
performance and avoid
premature engine wear:
• NEVER run the engine if the
ambient temperature is above
+40°C (+104°F) or below -16°C
(+5°F)
◆
If the ambient temperature
e40°C (+104°F) the
engine may overheat and
cause the engine oil to break
down.
◆
If the ambient temperature
falls below -16°C (+5°F)
rubber components such as
gaskets and seals will
harden causing premature
engine wear and damage.
◆
See your authorized Yanmar
marine engine dealer or
distributor if the engine will
be operated in either
temperature extreme.
• See your authorized Yanmar
marine dealer or distributor if
you need to operate the engine
at high altitudes. At high
altitudes the engine will lose
power, run rough, and produce
exhaust gases that exceed the
design specifications.
