2) Changing from automatic idle to manual idle
1. The idle mode is changed by pressing the return to idle control button (3) for 3 seconds. The audible warning
device (2) sounds for 3 seconds. The mode, "ON" or "OFF" is displayed on the control screen (LCD).
- "ON" = automatic return to idle
- "OFF" = manual return to idle by pressing the return to idle control button.
2. When the machine is started up, it will be in the previous return to idle mode.
3. If no function is operated and idle mode is "ON", the engine speed automatically returns to idle after 5 seconds.
(This timing can be changed to between 1 and 30 seconds).
4. If automatic idle is on and the engine is at idle, the engine speed automatically returns to the original speed when
one of the machine functions is operated.
5. If the automatic idle is on, the engine can be returned to idle by pressing the return to idle control button (3). But if
automatic idle is not on, the only way to return to idle is to press the control button (3).
6. When automatic or manual idle mode is on, the "ENG. IDLING" message appears on the control screen (LCD).
