Explanation
The Exhaust System Cleaning
Required indicator illuminates amber
when the exhaust system is in need of
a cleaning.
The indicator will be lit continuously
during the early stages of required
cleaning. If this condition continues,
the indicator will begin to flash and a
slight engine derate will occur.
If this condition continues further, the
Engine Warning Light (8) will illuminate
in addition to the Exhaust System
Cleaning Required indicator and a
severe engine derate will occur.
If the Exhaust System Cleaning
Required indicator illuminates or
flashes, start the manual cleaning
process (see Exhaust System
Cleaning Switch, page 3-10)
When the Exhaust System Cleaning
Switch (8) (Figure 3-6) is in the inhibit
cleaning position, this indicator will
illuminate and both manual and active
cleaning will be inhibited.
During the exhaust cleaning process, it
is possible for the engine exhaust to
reach temperatures exceeding 1200°
F. The HEST indicator will illuminate
red to warn the operator of when
temperatures reach 640°C (1184°F)
and will stay on until the temperature
falls below 1157° F (625° C).
