7.21 Exhaust gas treatment
The machine is equipped with a particulate matter catalyst for cleaning the
exhaust gas (only Tier IV).
The soot produced by burning diesel fuel is collected and burned in the
particulate matter catalyst at regular intervals. This process is called
regeneration.
Regeneration takes about 30 minutes. The more often the automatic
regeneration mode is corrected or modified, the longer regeneration
takes.
If the dirt in the particulate matter catalyst reaches a critical value, engine
power is reduced and machine operation has to be stopped.
Regeneration is only performed if the engine is at operating temperature.
Health hazard due to exhaust gases!
Can cause serious health hazards or death.
► Do not inhale exhaust gases.
► Use exhaust-gas suction systems suitable for exhaust-gas
temperatures of up to 600 °C (1,112 °F).
► Ensure sufficient ventilation during operation in enclosed premises.
Burn hazard at the exhaust system!
During regeneration, the exhaust system develops exhaust-gas
temperatures of about 600 °C (1,112 °F), even if the engine is running at
idling speed , which can cause serious burns or death.
► Keep a safe distance from the exhaust system.
Fire hazard during regeneration!
Hot exhaust gases in easily flammable environments cause serious injury
and death.
► In environments with easily flammable material, disable the automatic
regeneration mode.
► Do not perform manual regeneration in environments with easily
flammable material.
► Use only exhaust-gas suction systems suitable for exhaust-gas
temperatures of up to 600 °C (1,112 °F).
