4TNV98 & 4TNE98 Diesel Engine
Section 2. Periodic Maintenance
37
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 e113°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.
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.
CAUTION
NEVER use an engine starting aid such as ether.
Engine damage will result.
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.
