tion)

- backward) to find defects according to flash-
ing codes of signal lamps 18 or 19.
Note
In the event that the engine idle switch 15 is in the position
of idle speed and the engine diagnostics switch 16 is
switched off, it is possible to select, using the switch 17,
an idle engine speed within the range of 650 to 1,200 RPM
by repeated switching in the switch 17. By switching in the
upper half of the switch 17, the idle engine speed is
reduced. By switching in the lower half of the switch 17,
the idle engine speed is increased. The selected speed
is stored into the memory of the engine computer and it
is set to the last pre-selected value with a new start. Within
the factory setting, the idle engine speed is set to 850 RPM
and the machine parameters are adjusted at this setting.
