Before You Begin Servicing
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 30° (in any direction) or if an engine
runs for short periods of time (less than
three minutes) at an angle greater than
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.
TNV DI Service Manual
New Engine Break-in:
• On the initial engine start-up, allow the
engine to idle for approximately 15
0000007en minutes while you check for proper
engine oil pressure, diesel fuel leaks,
engine oil leaks, coolant leaks, and for
proper operation of the indicators
and / or gauges.
• During the first hour of operation, vary
the engine speed and the load on the
engine. Short periods of maximum
engine speed and load are desirable.
Avoid prolonged operation at
minimum or maximum engine speeds
and loads for the next four to five
hours.

• During the break-in period, carefully
observe the engine oil pressure and
engine temperature.
• During the break-in period, check the
engine oil and coolant levels
0000009en
frequently.
NEVER engage the starter motor while
the engine is running. This may damage
the starter motor pinion and / or ring
gear.
It is important to perform daily checks.
Periodic maintenance prevents

unexpected downtime, reduces the
number of accidents due to poor
machine performance and helps extend
the life of the engine.
