Yanmar 2TNV70 Operation Manual page 86

PERIODIC MAINTENANCE
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 +113°F (+45°C)
or below +5°F (-15°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 falls
◆
below +5°F (-15°C) rubber
components such as gaskets and
seals will harden causing premature
engine wear and damage.
Contact your authorized Yanmar
◆
industrial engine dealer or
distributor if the engine will be
operated in either temperature
extreme.
• Contact your authorized Yanmar
industrial engine 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.
CAUTION
NEVER hold the key in the START
position for longer than 15 seconds or
the starter motor will overheat.

For maximum engine life, Yanmar
recommends that when shutting the
engine down, you allow the engine to
idle, without load, for 5 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.
NEVER use an engine starting aid such
as ether. Engine damage will result.
Make sure the engine is installed on a
level surface. If a continuously running
engine is installed at an angle greater
than 30° (in any direction) or if an engine
runs for short periods of time (less than
3 minutes) at an angle greater than 35°
(in any direction) engine oil may enter
the combustion chamber causing
exessive engine speed and generate
white smoke. This may cause serious
engine damage.
