OPERATION

Starting

The starting method varies depending on the appli-
cation and specifications. Start the engine accord-
ing to the specified procedure.
Before starting the engine, check to make sure
no one is near the engine and tools are not left
on or near the engine. In loud voice, notify peo-
ple in the area when starting the engine.
Never load the engine at starting time. (Disengage
the clutch if it is installed.)
Warming-up Operation
Do not approach rotating parts while in opera-
tion.
Entanglement by rotating parts can cause seri-
ous injury.
Do not conduct warm-up operation for an extended
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 the
battery switch to OFF while the engine is in warm-
up operation causes malfunctioning of instruments
and deteriorates the diodes and transistors in the
alternator.
Never turn the key to START position. If so, starter
may be damaged.
During warming-up operation, do not load the
engine if exhaust smoke is black. Overloading the
engine (indicated by black smoke) not only causes
high fuel consumption but also excessive carbon
deposits inside the engine, thus it can reduce the
service life of the engine.
After the engine starts, operate at no load min.
rated speed speed for 5 to 10 minutes to warm up.

During warming-up operation
During warming-up operation, check if the oil pres-
sure is in the range of standard value.
Also, make sure the oil pressure gage is operating
properly.
Note: The oil pressure gage indicates higher pres-
sure than normal immediately after the
engine starts since the oil temperature is low.
This does not denote an abnormality. The
pressure gradually lowers to the normal level
as the oil temperature rises.
External inspection during warming-up
Check the external view of the engine to make sure
there is no fuel, oil, cooling water or exhaust gas
leakage from joints.
