Exhaust Filter Gauge Indicators and
Switches

A - Exhaust Filter Cleaning Switch:

This switch con-

trols the function of the exhaust filter. It has 3 positions
as follows:

A1 Center position:

In this position the exhaust fil-

ter cleaning procedure is set to the automatic
(AUTO) mode. Operating the engine in this cen-
ter AUTO Mode allows the ECU to perform intel-
ligent exhaust filter cleaning as required.

A2 Bottom position:

In this position the auto exhaust

filter cleaning is disabled.

A3 Top position:

In this position the operator initi-

ates a manual exhaust filter cleaning operation.
This process allows the system to clean the
exhaust filter when the operator previously dis-
abled exhaust filter cleaning by pressing the bot-
tom of the switch. The top of the switch will need
to be pressed for at least three seconds, and the
park brake engaged to activate. The indicator in
the switch will illuminate when activated and be
off when the exhaust filter cleaning is complete.

B - Exhaust Filter Gauge:

This gauge displays the

four indicators you will see through the operator initi-
ated or auto exhaust filter cleaning and disable
processes.

NOTE:

The indicators in the exhaust filter gauge

will all illuminate when the keyswitch is put in the
“ON” position for a momentary lamp check.
During normal operation all lamps will never all be
illuminated at the same time. This image is only to
illustrate the indicators you may see during oper-
ation.

B1 - Exhaust Filter Cleaning Indicator:

This

indicator will illuminate when exhaust gas tem-
perature is at optimal regeneration temperature,
elevated idle is active, or exhaust filter cleaning is
in process.

When this indicator is illuminated, the machine
can be operated as normal unless the operator
determines the machine is not in a safe location
for high exhaust temperatures and disables auto
cleaning.

B2 - Auto Cleaning Disabled Indicator:

This

indicator will illuminate when the operator has
disabled the auto exhaust filter cleaning function
from the exhaust filter cleaning switch (A). This
icon will remain illuminated until the operator re-
engages automatic exhaust cleaning from the
exhaust filter cleaning switch (A). Disabling the
auto mode is not recommended for any situation
unless it is safety related or if the fuel tank lacks
the recommended 1/4 tank of fuel to complete the
cleaning process.

B3 - Exhaust Filter Indicator:

This indicator

will illuminate when the exhaust filter is in need
of cleaning because the soot level of the exhaust
filter is slightly high and the operator has disabled
auto exhaust filter cleaning. If conditions are safe,
the operator should enable the auto exhaust filter
clean setting or perform manual exhaust filter
cleaning.

B4 - Exhaust Filter Warning Indicator:

This

amber or red indicator works in combination with
the Exhaust Filter Indicator (B3).

•

If this indicator is illuminated amber when the
Exhaust Filter Indicator (B3) is illuminated, the
engine performance will be reduced by the ECU
because the soot level of the exhaust filter is mod-
erately high. If conditions are safe, the operator
should enable the auto exhaust filter clean func-
tion. If conditions are not safe, the operator should
move the machine to a safe location and engage
the auto exhaust filter cleaning mode.

•

If this indicator is illuminated red when the
Exhaust Filter Indicator (B3) is illuminated, the
engine performance will be further reduced by the
ECU because the soot level of the exhaust filter is
extremely high. If this combination is present, con-
tact your authorized Gehl dealer.

•

This indicator will also illuminate red when an
engine fail condition exists. Refer to the multi-
function screen for error code information.
