Diesel Particle Filter Regeneration; Manual Brake - Signalization - Zetor FORTERRA HD Series Operator's Manual

Diesel particle filter regeneration

During the operation of a tractor, diesel particle
filter is clogged by solid particles originating in engine run
when burning fuel. Clogged diesel particle filter
automatically regenerates the temperature of exhaust
fumes with higher load of the engine.
When operating the tractor with low load of the engine ,
e.g. with long-term operation on idle run, there is a partial
clogging of diesel particle filter. This condition is signalized
with the engine run by a lit red control of diesel particle
filter, and followingly also by acoustic signal and on the
display of displaying unit of diesel particle filter by failure
code
E:36
If this situation occurs, increase the load of engine and
continue working until red control of diesel particle filter
switches off and acoustic signal does not stop.
By increasing the engine load, the temperature of exhaust
fumes increases and the solid particles which clog diesel
particle filter burn.
The conditions suitable for diesel particle filter
regeneration are signalized by a lit green control on the
dashboard.
Depending on the temperature of exhaust fumes and the
degree of diesel particle filter clogging, regeneration can
take up to thirty minutes.
When regeneration is achieved, notification
information signalization goes out (error 36). If this
signalization does not go out, repeat this procedure. If
it still does not go out, you need to address an
authorized service.
Increased load of engine shall be work with
a tractor at higher engine revolutions(1 800 RPM) with
connected tools, power intake via PTO shaft or outer
hydraulic circuit.

Manual brake - signalization

If the tractor is not braked by a manual brake, a warning is
displayed on a display (a letter P in a circle) and at the
same time there is a sound signal.
This situation occurs in two cases
a - a tractor unbraked by a manual brake with engine
running and a driver leaves its seat
b - a tractor unbraked by a manual brake standing with
engine off and the key is shifted in '0' position.
Brake the tractor with a manual brake.
