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.

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, coolant leaks, and for
proper operation of the indicators
and / or gauges.
• During the first hour of operation, vary
the engine speed and 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 4 to 5 hours.
• During the break-in period, carefully
observe the engine oil pressure and
engine temperature.

engine oil and coolant levels
frequently.
