Caution

Failur e perform a r egeneration a timely manner after notification may r esult engine a clogged diesel particulate filter , damage the filter and engine

Danger

During the regeneration process (with either system), the temperature the exhaust gases will elevated. NOT park stop for extended period under low hanging overhead flammable objects such trees, awnings, structures, etc., that could damaged elevated exhaust temperatures. Further , the vehicle being operated area where flammable vapors exist, the regeneration process must interrupted. Failure heed these cautions may result fire explosion causing serious personal injury death.

When regeneration needed, icon the top the DPF Smart switch will illuminate notify the vehicle operator . The DPF Smart switch allows the vehicle operator either stop start regeneration. (Certain conditions must met, however , before regeneration can manually started.)

Note: the vehicle a location that may hazardous when active regeneration begins (i.e., close proximity flammable materials gases), the regeneration should stopped pushing the DPF switch the active regeneration stopped the vehicle operator , should initiated a later time when the vehicle a safe location. However , active regeneration stopped the vehicle may need taken a MACK service facility The service facility will use a service tool manually initiate the regeneration.

W Arning

The temperatur e the exhaust system components during the r egeneration ocess can exceed 500°C (1000°F). V arious factors (including ambient temperatur e and duration the r egeneration ocess) determine when these components will r eturn normal operating temperatur e after r egeneration has completed. extr emely car eful ound these hot components. Contact with these components can r esult serious personal injury .

DPF INHIBIT ROAD SPEED LIMITING (RSL)

The DPF Smart Switch can locked into the DOWN (or Inhibit Regen) position the driver . the DPF Smart Switch remains the locked position, the following vehicle speed limiting will occur:

1 V ehicle vehicle moving with the DPF Smart Switch the locked (DOWN) the vehicle speed will decrease down kph (10 mph) below the current speed until the driver releases the switch back the neutral (MIDDLE) https://www.truck-manuals.net/mack/

2 V ehicle Stationary and then Moving. the vehicle stationary with the DPF Smart Switch the locked (DOWN) position and the driver then begins move the truck, the vehicle speed will limited kph (10 mph) until the driver releases the switch back the neutral (MIDDLE) position.
