Safety Precautions
NOTICE
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.
NOTICE
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.
TNV IDI Service Manual
NOTICE
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.
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.
NOTICE
• Only use the engine oil specified. Other engine
oils may affect warranty coverage, cause internal
engine components to seize and / or shorten
engine life.
• Prevent dirt and debris from contaminating the
engine oil. Carefully clean the oil cap / dipstick
and the surrounding area before you remove the
cap.
• NEVER mix different types of engine oil. This may
adversely affect the lubricating properties of the
engine oil.
• NEVER overfill. Overfilling may result in white
exhaust smoke, engine overspeed or internal
damage.
