Regeneration operating procedure
1. Start the engine.
Make sure that the DPF inhibit switch lamp is “OFF” .
Switch lamp “OFF” : Auto regeneration mode activated.
Switch lamp “ON” : Regeneration inhibit mode activated.
NOTE :
• When the engine is started, the “Auto regeneration” mode is automatically activated.
• “Regeneration inhibit” mode is activated when the DPF inhibit switch is pushed after the engine is
started.
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 the working
place is in a safe area as DPF and exhaust temperature will rise.
3. When the engine rpm increase indicator starts flashing:
Keep on working and increase the engine rpm until the indicator turns “OFF” .
NOTE :
• Even if the auto regeneration mode is selected, DPF regeneration may not begin because system
requirements have not been satisfied.
• 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.
