Starting Engine - Komatsu D155A-6 Operation & Maintenance Manual

OPERATION

STARTING ENGINE

NORMAL STARTING
Sit down in the operator's seat before starting the engine.
Do not attempt to start the engine by short-circuiting the engine starting circuit. Such an act may cause serious bodily injury
or fire.
Check that there are no persons or obstacles in the surrounding area, then sound the horn and start the engine.
Exhaust gas is toxic. When starting the engine in confined spaces, be particularly careful to ensure good ventilation.
NOTICE
Do not crank the starting motor continuously for more than 20 seconds.
If the engine does not start, wait for at least 2 minutes, then repeat the
procedure from Step 2.
Before starting the engine, check that the fuel control dial is in the low
idling (MIN) position.
On this machine, to protect the turbocharger, a turbo protect function is
provided. In cold weather, even if fuel control dial (1) is moved
immediately after starting the engine, the engine speed may not change
for several seconds.
If the fuel control dial is in the FULL position, the engine will accelerate
suddenly and cause damage to the engine parts, so set it to an
intermediate or low speed position.
1. Set fuel control dial (1) to the low idling (MIN) position.
If the dial is at the high idling (MAX) position, always change it
to the low idling (MIN) position.
2. Insert the key into starting switch (2) and turn the key to the
START position (C). The engine will start.
