INDICATION
DESCRIPTION
Fig 70. Engine Indicator Chart
The HEST indicator will be displayed by itself when
the exhaust temperature is elevated due to an
automatic regeneration. The Telehandler may be
operated in this condition as long as there is no
concern for operating with high exhaust temperature.
The HEST Indicator will be displayed with a flashing ESC
Indicator when the exhaust temperature is elevated due to a
manual regeneration. The Telehandler must not be operated
in this condition.
The ESC Regen Disabled indicator will be displayed
if the ESC Regen has been manually disabled by
the user. The Telehandler should only be operated
in this condition if it is in an area where the high
exhaust temperature could cause problems, such as near
combustibles. As soon as the concern for high exhaust
temperature subsides, the automatic regeneration should be
enabled by pressing the Enter button or Regen soft button to
bring up the After Treatment Control menu and then pressing
the Regen Mode Auto soft button.
