Cleaning of Exhaust Filter

Cleaning of Exhaust Filter The exhaust filter retains the smut coming from the exhaust gas and decreases the emission values. With the exhaust filter cleaning operation which can be performed automatically or manually, the smut retained in the filter is burned with regular intervals so that the filter is emptied before filling up and being clogged. In this operation, the exhaust gas is heated by the engine and smut is burned. Driver is informed about the exhaust filter cleaning of the vehicle through the messages displayed on the indicator panel and explained in detain in the following sections WARNING Since the exhaust gas temperature is high during the exhaust filter cleaning; ensure that the vehicle is not in the same place with flammable (dry grass, leaves), inflammable and explosive materials or in enclosed space Otherwise, fire risk may occur. WARNING Ensure that vehicle exhaust cleaning is not performed in locations like hazardous material loading and unloading places or fuelling stations. When necessary, activate the exhaust filter cleaning blocking using exhaust filter cleaning prevention button.

When the fill rate of exhaust filter exceeds 100%, 9th level of the graphic shall start to flash. You may continue normal operation of your vehicle in this case. Optionally, you may perform a manual exhaust filter cleaning on your vehicle. When the last level of the graphic is filled, final 2 levels of the graphic shall start to flash. In this case, your vehicle is prevented from performing an automatic exhaust filter cleaning to protect the exhaust filter.

Graphic Example WARNING

When the exhaust filter reaches a specific fill rate, automatic filter cleaning operation shall start and the soot inside the filter shall be burnt under high temperature. It may be difficult for exhaust gas to reach high temperatures and automatic filter cleaning may be required to be repeated in vehicles that are used with low loads, frequent start and stop operations, operated in idle for long periods and used in short distances (e.g.construction vehicles, mixer series).
