Chapter 3 OPERATION
Start
The starting method varies depending on the application and specifications. Start the engine according to the spec-
ified procedure.
Warming-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 (0.3 MPa {3.1 kgf/cm
2
}
[21 psi] or more).
Also, make sure the oil pressure gauge is actuated
properly.
External Inspection During Warm-up
During warm-up operation, walk around the engine
and check for fuel, oil, coolant or exhaust gas leaks.
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 equipped.)
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 1 minute before
cranking again.
Do not approach rotating parts during operation. Entanglement by rotating parts can result in serious injury.
