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.
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 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 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.
