●
When continuing operation about ten hours without
conducting manual regeneration even while

”
is lighting, it will
be impossible to conduct manual regeneration and it
leads to low idling operation only. In this case, it
becomes necessary to clean DPF (Diesel particulate
filter). Please contact our nearest dealer.
 When DPF regeneration required lamp goes on, take immediate specified action to
conduct manual regeneration.
If it is continuously operated without manual regeneration, excessive soot will
accumulate and it could damage DPF due to abnormal burning, and it could cause a
fire.
 Do not stop engine during enforced regeneration operation, except for unavoidable
conditions.
