17OPERATING THE ENGINE
BRegeneration Operating Procedure
1. Start the engine and press the auto regeneration switch, and the switch lamp illuminates.
Operating Procedure for Auto Regeneration Mode
(1) Auto regeneration switch
(2) Parked regeneration switch
(3) Regeneration indicator
(4) Engine RPM increase indicator
(5) Engine warning indicator
(6) Parked regeneration indicator
Switch lamp ON: Auto Regeneration Mode activated.
Switch lamp OFF: Inhibit Mode activated.
A When the key switch is turned off, the regeneration system returns to Inhibit Mode (Default). To select the Auto
Regeneration Mode, turn on the key switch and press the auto regeneration switch. Check to make sure the switch
lamp stays on.
2. When the regeneration indicator starts flashing:
A specific amount of PM has built up in the DPF.
Continue to operate the tractor, and the regeneration process will begin automatically, make sure you are
working in a safe area as DPF and exhaust temperature will rise.
When the engine rpm increase indicator starts flashing, keep on working and increase the engine rpm until
the indicator turns off.
A Even if the Auto Regeneration Mode is selected, DPF regeneration may not begin because system requirements
have not been satisfied.
A The engine rpm increase indicator is used as a guide to satisfy the regeneration conditions. If the engine load is
too heavy, the engine rpm increase indicator may continue to flash, even though regeneration system conditions
are satisfied and regeneration may begin automatically. (See the tips on the DPF regeneration.)
3. When the regeneration conditions are satisfied:
The regeneration indicator stops flashing and remains constant "ON".
The regeneration starts automatically whether the tractor is in motion or stationary.
When the regeneration cycle has completed, the indicator turns "OFF".
A If you press the auto regeneration switch during regeneration, the regeneration cycle will be interrupted. (The
Inhibit Mode is now activated (Default mode). Auto Regeneration Mode is turned "OFF".)
A During regeneration, do not lower the engine rpm. Otherwise, the regeneration cycle may be interrupted.
