When the starting switch is in the ON position before start-
ing the engine, lamps (1) in the diagram on the right light
up for approx. 3 seconds and the alarm buzzer sounds for
approx. 3 seconds.
After 3 seconds all lamps except lamps (2) go out.
Lamps (2) go out after the engine starts.
If any lamps do not light up there is probably a failure or a
disconnection, so please ask your Komatsu distributor to
carry out inspection.
q When the starting switch is turned ON, if the directional
lever is not at the neutral position, the central warning lamp
lights up and the alarm buzzer sounds intermittently. If this
happens, return the directional lever to the neutral position.
The lamp will go out and the buzzer will stop.
q Directional lever (6): Neutral position
Directional selector actuation switch (3): ON position
Directional selector switch (4): Forward or Reverse position
When the starting switch is turned to the ON position with
the levers and switches as above described, all directional
lever positional pilot lamps (5) will go out.
If directional selector switch (4) is then set to the N posi-
tion, directional lever positional pilot lamps (5) display the
normal condition “N“.
