Note:
The DEF Tank filler area must be protected or shielded from solid or liquid debris falling from normal refuse pick up op-
erations or body clean out operations.
Safety Information
MACK utilizes a diesel particulate filter (DPF) and selective catalytic reduction (SCR) to meet US2017 emissions. The sys-
tem is designed to require very little driver interface to maintain correct operation. The technology utilizes a aftertreatment
DPF passive regeneration; requiring no fuel to be injected to clean the DPF. In US 2007 an active regeneration (fuel was in-
jected) was required to clean out the DPF producing very high exhaust outlet temperatures. Certain vocational duty cycles
will require the use of fuel and/or a DPF parked regeneration to clean out built-up soot in the particulate filter. Exhaust gas
temperatures (EGT) will increase during a parked regeneration. When parking the vehicle to perform a parked regeneration
keep away from any flammable materials, vapors or structures.
DANGER
Exhaust gases and components can be at extremely high temperatures during aftertreatment DPF regeneration. When
parking the vehicle, keep away from any flammable materials, vapors, or structures.
DANGER
The temperature of the exhaust system components during the aftertreatment DPF regeneration process can exceed 350
° C (660 ° F). The exhaust gas leaving the system can reach 505 ° C (930° F). Various factors (including ambient air tem-
perature (AAT) and duration of the regeneration process) determine when these components will return to normal operat-
ing temperature after regeneration has completed. Be extremely careful around these hot components. Contact with these
components can result in serious personal injury.
