Automatic (AUTO) Exhaust Filter Cleaning

Automatic exhaust filter cleaning is started when soot in the exhaust filter reaches a certain level. This occurs less frequently if the engine is operated for long periods under conditions where passive exhaust filter cleaning takes place. Automatic exhaust filter cleaning is initiated and performed without any intervention on the part of the operator. Automatic exhaust filter cleaning is performed only if the relevant function is activated on the exhaust filter cleaning mode switch.

If the system determines that soot buildup in the exhaust filter requires cleaning and engine speed is above 1200 rpm, an automatic cleaning is initiated and performed without any intervention on the part of the operator. High Exhaust Temperature Indicator (B) remains illuminated during the exhaust filter cleaning.

Do not disable automatic exhaust filter cleaning unless it is absolutely necessary.

CAUTION: To prevent fires, be sure to routinely clear any combustible materials (crop debris, animal nests, etc.) from the area of the engine and exhaust filter. Exhaust filter cleaning uses extremely high temperature.
