Chapter 3 OPERATION
Starting
The starting method changes based on the application and specifications.Start the engine according to the specified
procedure.
Warm up operation
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 warm up operation, check if the oil pressure is
in the range of standard value (0.15 MPa {1.5 kgf/cm
2
}
[21 psi] or more).
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 en-
gine 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 fuel,
engine oil and coolant leakage, or exhaust gas leak-
age from joints.
Before starting the engine, check to make sure no one is near the engine and that tools are not left on or near the
engine.In a loud voice, notify people in the area when starting the engine.
Do not apply a load to the engine at starting. (Disengage the clutch if installed.)
Continuous operation of the starter will drain the battery power and cause the starter to seize. Do not use the
starter for more than 10 seconds at a time. When the engine does not start, wait for more than one minute before
cranking again.
Do not approach rotating parts during operation. Entanglement by rotating parts can cause serious injury.
