OPERATING THE ENGINE
IMPORTANT :
• When ambient temperature is so low or when working with such extraordinary use of electricity that
the regeneration conditions are not satisfied, the regeneration indicator starts flashing.
If the regeneration indicator turns "ON" for a while and then starts flashing, keep on working
and rev up the engine to the maximum rpm so that the regeneration indicator stops flashing and
remains "ON".
3. When the engine-rpm-increase indicator
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.
