DEF (Diesel Exhaust Fluid) level pilot lamp
(10)
This warning lamp indicates, when illuminated, that exhaust
temperatures are high due to SCR cleaning.
The lamp will also illuminate during a manual SCR cleaning.
When this lamp is illuminated, be sure the exhaust pipe outlet is
not directed at any surface or material that can melt, burn, or
explode.
When this lamp is illuminated, the exhaust gas temperature
could reach 800 ˚C [1500 ˚F], which is hot enough to ignite or
melt common materials, and to burn people.
The lamp does not signify the need for any kind of equipment
or engine service; It merely alerts the equipment operator to
high exhaust temperatures. It will be common for the lamp to
illuminate on and off during normal equipment operation as
the engine completes the SCR cleaning.
