SYSTEM OF ADDITIONAL TREATMENT OF EXHAUST GASES

Limitation of the engine power and engine revolutions

If there is a serious error of SCR system or if the level of urea in the tank is low, the reaction of the system is
reduced engine power output and revolutions.
According to the error type, so-called one-stage or two-stage reduction of engine output is performed.
stage 1 Reduction of engine power by 20%
stage 2 Reduction of engine power by 20%
Reduction of engine revolutions to 1,200 rpm

Indication of amount of urea in the tank

The amount of urea in the tank is displayed on the
corresponding main screen in percentage of the urea tank
volume.
Small amount of urea in the tank is indicated with urea
signal lamp (1), defect signal lamp (2), acoustic signal and
reduced engine power output and revolutions.

Long-term shutdown of tractor

During a long-term shutdown of the tractor, the urea filling must be drained from the tank.
Before operating the tractor, the urea tank must be filled with a new filling again and the urea filter element
must be replaced.
The urea filling should not stay in the tank longer than four month; then it should be replaced.

Repairs and maintenance of the system of additional treatment of exhaust gases

All repairs and maintenance of the system of additional treatment of exhaust gases must
always be performed by a professional service All interventions in the system, except authorised
service, are prohibited.
