PERIODIC MAINTENANCE
5-12 TNV IDI Service Manual
Introduction
CAUTION
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.
• Avoid operating in a corrosive
atmosphere such as salt water spray.
• NEVER install the engine in a
floodplain unless proper precautions
are taken to avoid being subject to a
flood.
• NEVER expose the engine to the rain.

CAUTION
Observe the following environmental
operating conditions to maintain engine
performance and avoid premature
engine wear:
• The standard range of ambient
temperatures for the normal operation
of Yanmar engines is from +5°F (-15°C)
to +113°F (+45°C).
• If the ambient temperature exceeds
+113°F (+45°C) the engine may
overheat and cause the engine oil to
break down.
• If the ambient temperature is below
+5°F (-15°C) the engine will be hard to
start and the engine oil may not flow
easily.
• Contact your authorized Yanmar
industrial engine dealer or distributor
if the engine will be operated outside
of this standard temperature range.

CAUTION
NEVER hold the key in the START
position for longer than 15 seconds or
the starter motor will overheat.
0000007en
CAUTION
For maximum engine life, Yanmar
recommends that when shutting the
engine down, you allow the engine to
idle, without load, for five minutes. This
will allow the engine components that
operate at high temperatures, such as
the turbocharger (if equipped) and
exhaust system, to cool slightly before
the engine itself is shut down.
0000008en
CAUTION
NEVER use an engine starting aid such
as ether. Engine damage will result.
0000009en
CAUTION
Make sure the engine is installed on a
level surface. If a continuously running
engine is installed at an angle greater
than (IDI = 25°, DI = 30°) in any direction
or if an engine runs for short periods of
time (less than three minutes) at an
angle greater than (IDI = 30°, DI = 35°) in
any direction, engine oil may enter the
combustion chamber causing excessive
engine speed and white exhaust smoke.
This may cause serious engine damage.
