7 Maintenance
Manually regenerate the exhaust after-treatment system
1. Run the diesel engine warm (coolant temperature at least 75 °C (167 °F)).
2. Park the machine on firm, non-flammable ground.
3. Lower the loader unit to the ground.
4. Apply the parking brake.
5. Do not stop the diesel engine, but let it run at idling speed.
6. Disable the lock for the operating hydraulics/road travel
– see chapter 5 “3rd control circuit” on page 5-40.
7. Start regeneration. To do this: press push button 49 to position A.
➥ Regeneration is in operation.
➥ Engine speed is automatically increased.
➥ The time required for regeneration is about 30 minutes.
8. Regeneration has finished successfully if:
➥ the idling speed of the diesel engine reduces,
➥ the symbol G/2 in the digital display as well as the warning light 66
goes out.
If the regeneration is interrupted for any reason (symbol G/2 flashes,
warning light 66
lights up, acoustic warning ON), then the entire
regeneration must be repeated as described above.
If the regeneration is interrupted again, have the exhaust after-treatment
system checked or replaced by an authorized service center.
Cleaning/replacing the diesel particulate filter (option)
During its entire service life, the diesel particulate filter also collects ash
that is not removed by regeneration.
This ash load over time leads to reduced regeneration intervals, which
then makes the replacement of the diesel particulate filter necessary as
part of maintenance.
The diesel particulate filter may only be cleaned or replaced by an
authorized service center.
Danger of engine damage within very short time under maximum load
condition!
► Immediately park the vehicle and switch off the diesel engine.
► Contact an authorized service center.
