DPF Regeneration (PIN required) allows an operator or technician to initiate
a stationary regeneration for the exhaust system DPF (diesel-particulate filter)
on the machines with Yanmar diesel engines. If the engine ECU identifies
that a stationary DPF regeneration is necessary, an advisory will occur on the
InfoCenter display.
Move the machine to a well ventilated area and initiate a stationary DPF
regeneration by pressing the left/right button (as indicated by the
bottom of the screen) and then pressing the down button (as indicated by the
Yes or at the bottom of the screen). Additional information can be found in
the Yanmar Engine Service Manual.
DPF Ash (PIN required) DPF ash is the level of ash accumulated in the DPF
(diesel-particulate filter) on the machines with Yanmar diesel engines. Ash
is the byproduct of performing numerous regeneration operations. An engine
fault will be generated if the ash accumulation exceeds 50 g/l. If excessive ash
accumulation levels exist, DPF replacement may be necessary.
