3.1.2 PM warning level and required procedures for Auto Regeneration Mode
During
“Auto Regeneration Mode”
when the PM level has built up in the DPF, the regeneration cycle will begin
automatically. If the regeneration cycle is interrupted or the regeneration conditions are not satisfied, the buzzer starts
sounding and the indicator display changes in response to the PM level in order to prompt the operator to perform the
required procedure listed in the following table.
IMPORTANT :
• Once the regeneration level has been reached, immediately perform the required procedure for
regeneration.
Interrupting the regeneration cycle or continuing operation by while ignoring the warning signs may
cause DPF and engine damage.
