170 Mack, US10 Emissions Solution
Note: If the vehicle is in a location that may be hazardous when an active regeneration
begins (i.e., in close proximity to flammable materials or gases), the regeneration
should be stopped by pushing the DPF switch to the "Stop Regeneration" position.
If an active regeneration is stopped by the vehicle operator, it should be initiated at a
later time when the vehicle is in a safe location. However, if an active regeneration is
stopped too many times, the vehicle must be taken to a MACK service facility. The
service facility will use a service tool to manually initiate the regeneration.
WARNING
The temperature of the exhaust system components during the regeneration
process 350 degrees C (660 F). The exhaust gas leaving the system can reach
505 degrees C (930 F). Various factors (including ambient temperature and
duration of the regeneration process) determine when these components will
return to normal operating temperature after regeneration has completed.
Be extremely careful around these hot components. Contact with these
components can result in serious personal injury.
CAUTION
When the inhibit position is pressed, the switch will remain in a locked position. It
is important, therefore, to immediately set the switch back to the neutral position
when safe to do so. Failure to set the switch back to the neutral position may result
in an engine derate, clogged diesel particulate filter or damage to the filter.
DPF INHIBIT ROAD SPEED LIMITING (RSL)
The DPF Smart Switch can be locked into the DOWN (or Inhibit Regen)
position by the driver (if equipped). If the DPF Smart Switch remains in the
locked position, the following vehicle speed limiting will occur:
1 Vehicle Moving. If vehicle is moving with the DPF Smart Switch in the locked
(DOWN) position, the vehicle speed will decrease down to 16 kph (10 mph) below
the current speed until the driver releases the switch back to the neutral (MIDDLE)
position.
2 Vehicle Stationary and then Moving. If the vehicle is stationary with the DPF
Smart Switch in the locked (DOWN) position and the driver then begins to move
