Mack, Emissions Solution 183
DANGER
During the regeneration process, the temperature of the exhaust gases will be elevated.
DO NOT park or stop for an extended period under low hanging overhead flammable
objects such as trees, awnings, structures, etc., that could be damaged by elevated
exhaust temperatures. Further, if the vehicle is being operated in an area where
flammable vapors exist, the regeneration process must be interrupted. Failure to heed
these cautions may result in fire or explosion causing serious personal injury or death.
Note: Do not initiate a parked regeneration if the vehicle is in a location that may be
hazardous (i.e., in close proximity to flammable materials or gases),
If a parked 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 a parked 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 exhaust gas leaving the system can reach 500–625 ° C (932–1157° 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.
