Yanmar L48N Operation Manual page 23

CAUTION
Make sure the engine is installed on a
level surface. If a continuously running
engine is installed at an angle greater
than 20° (in any direction) or if an engine
runs for short periods of time (less than
3 minutes) at an angle greater than 25°
in any direction, engine oil may enter the
combustion chamber causing exessive
engine speed and generate white smoke
and also may occur unsatisfactory oil
pressure. These may cause serious
engine damage.
CAUTION
New Engine Break In:
• On the initial engine start-up, allow the
engine to idle for approximately 15
minutes while you check for proper
engine oil pressure, diesel fuel leaks,
engine oil 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 100 hours.
• During the break-in period, carefully
observe the engine oil pressure and
engine temperature.
• During the break-in period, check the
engine oil levels frequently.
CAUTION
NEVER engage the starter motor while
the engine is running. This may damage
the starter motor pinion and / or ring
gear.
