Safety Information

Mack utilizes the use a Diesel Particulate Filter (DPF) and Selective Catalytic Reduction (SCR) meet A2010 The system designed require very little driver interface maintain correct The technology utilizes a passive regeneration; requiring fuel injected clean the DPF A2007 active regeneration (fuel was injected) was required clean out the DPF producing very high exhaust outlet

Danger

Exhaust gases and components can extremely high temperatures during When parking the keep away from any flammable

Danger

Certain vocational duty cycles will require the use fuel and/or a parked regeneration clean out built - soot the particulate filter Exhaust temperatures will increase during a parked When parking the vehicle perform a parked regeneration keep away from any flammable vapors

The temperature the exhaust system components during the regeneration process can exceed 350 degrees C (660 The exhaust gas leaving the system can reach 505 degrees C (930 V arious factors (including ambient temperature and duration the regeneration process) determine when these components will return normal operating temperature after regeneration has extremely careful around these hot Contact with these components can result serious personal injury .
