Operating precaution

Be sure to break in the engine!
During the first 50 hours of operation, break in the
engine by using lighter loads and lower speeds
than normal. A proper break in contributes to the
maximum service life of the engine.
Warm up the engine before
operation!
After starting the engine, leave it idling for 5 to 10
minutes before operating under full load, for
maximum engine life.
NOTE: Long periods of warming up the engine are
not recommended. They can deposit carbon in
cylinders and cause incomplete fuel combustion.

Warm-up
ENGLISH
Stop the engine only after it has
cooled down!
Stopping the engine immediately after it has been
working under a load, can result in overheating
and accelerated wear of the engine components.
Before stopping the engine, leave it idling for 5 to
10 minutes. This allows the hot areas in the
engine to cool down gradually, which extends
engine life. While the engine is running, make a
walk-around inspection to make sure everything is
functioning properly.
Use the starting motor correctly!
When starting the engine, do not crank it for more
than 10 seconds at a time. After every 10 seconds
of engine cranking, allow 30 seconds for the
starting motor to cool before cranking it again.
