Warming-up operation
:$51,1*
Do not approach rotating parts during operation.
Entanglement by rotating parts can cause serious
injury.

Do not conduct warm-up operation for a prolonged
period of time.
Prolonged warm-up operation causes carbon buildup
in the cylinders that leads to incomplete combustion.
Do not turn the battery switch to OFF. Turning off the
battery switch while the engine is in warm-up opera-
tion not only stops the instrument operations but also
may deteriorate the alternator diode and regulator.
Never turn the key to the START position during
warm-up operation, as it damages starter.
During warming-up operation, do not operate the
engine in an overloaded condition (if overloaded,
black smoke is exhausted). Operating the engine in
an overloaded condition not only increases fuel con-
sumption but also generates excessive carbon depos-
its inside the engine which considerably shortens the
service life of the engine.
After the engine starts, operate the engine in a no load
condition at low idling speed for 5 to 10 minutes to
warm up the engine.
Checking engine oil pressure
During warming-up operation, check if the oil pressure
is in the range of standard value.
Also, make sure the oil pressure gauge is operating
properly.
Note:
The oil pressure gauge may indicate a higher
level than normal level immediately after the
engine starts, due to the low oil temperature.
The pressure gradually lowers to the normal
level as the oil temperature rises.
External inspection during
warm-up
Visually check the external view of the engine for
leaks of fuel, engine oil and coolant, or leaks of
exhaust gas from joints.
