NOTICE
If any indicator illuminates during engine
operation, stop the engine immediately.
Determine the cause and repair the problem
before you continue to operate the engine.
If the alarm window with audible alarm fails
to display and go out about three seconds
later when the ignition switch is in the ON
position, see your authorized Yamar marine
dealer or distributor for service before
operating the engine.
Observe the following environmental
operating conditions to maintain engine
performance and avoid premature engine
wear:
• Avoid operating in extremely dusty
conditions.
• Avoid operating in the presence of
chemical gases or fumes.
• 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 is below -16°C
(+5°F), rubber components such as
gaskets and seals will harden causing
premature engine wear and damage.
• Contact your authorized Yanmar marine
engine dealer or distributor if the engine
will be operated outside of this standard
temperature range.
NEVER engage the starter motor while the
engine is running. Damage to the starter
motor pinion and / or ring gear will result.
