Manual regeneration
Important information about the manual regeneration
If the symbol G/2 or the symbol G/4 flashes, the exhaust after-treatment
must be manually regenerated.
The symbol G/4 only appears if a diesel particulate filter (optional) is
installed in the vehicle.
Important! Before changing the oil, a manual regeneration of the exhaust
after-treatment system (DOC and SCR catalytic converter) must be
performed for DEUTZ engines with EU exhaust emission level IV (EPA
tier4f) .Then the maintenance counter must be reset in the DEUTZ engine
controller.
The parts of the exhaust after-treatment become very hot. There is a
risk of fire and explosion!
Failure to observe this can cause serious injury.
► When stopping the machine while the engine is running, ensure that
there is no flammable or combustible material in the immediate vicinity
of the exhaust opening (for example paper, dry grass, straw, wood,
wood ceilings, oil, fuel, etc.).
► Do not touch the area of the exhaust outlet since regeneration
(combustion of soot) creates temperatures of about 650 °C (1202 °F)!
► Perform manual regeneration only outdoors, not in enclosed premises.
The manual regeneration of the exhaust after-treatment system can only
be performed if the following points are met:
► Park the machine on firm, non-flammable ground.
► The machine must not be moved during regeneration.
(The time required for regeneration is about 30 minutes.)
► Engine coolant temperature must be at least 75°C (167°F).
► Hand brake applied.
► Work hydraulics locked.
