Summary
REGENERATION IN PTO MODE. WHEN A VEHICLE IS BEING OPERATED IN PTO MODE AND A DIESEL PARTICULATE FILTER (DPF) REGENERATION IS COMMANDED (EITHER AUTOMATICALLY OR MANUALLY), THE ENGINE MUST BE RUN AT A SPEED ABOVE THE MINIMUM SPEEDS LISTED IN THE TABLES BELOW (ACCORDING TO THE ALTITUDE AND AMBIENT TEMPERATURE IN WHICH THE VEHICLE IS BEING OPERATED) SO THAT SUFFICIENT HEAT CAN BE GENERATED IN THE CATALYST FOR REGENERATION TO OCCUR.

FSB 210-045, Regeneration in PTO Mode
(June 2015)
When a vehicle is being operated in PTO mode and a diesel particulate filter (DPF)
regeneration is commanded (either automatically or manually), the engine must be run at a
speed above the minimum speeds listed in the tables below (according to the altitude and
ambient temperature in which the vehicle is being operated) so that sufficient heat can be
generated in the catalyst for regeneration to occur.
Note: This bulletin does not apply to Mack Trucks Australia.
This is important to note, because the rated speed of the PTO must not be exceeded. For
example; if the maximum rated speed of the PTO is 900 rpm, the regeneration will not occur
while the PTO is engaged. When specifying a PTO for a chassis equipped with a DPF, a PTO
having a maximum rated speed above the minimum engine speed listed in the tables below
must be specified.
