PROCEDURE FOR MANUAL STATIONARY REGENERATION
k k
Exhaust gas temperature may increase higher than the
previous models during the aftertreatment devices regen-
eration. Avoid getting near the exhaust pipe outlet and
around the aftertreatment devices to prevent being burnt.
Also, keep combustible materials away from the exhaust
pipe outlet and around the aftertreatment devices to pre-
vent a fire.
The manual stationary regeneration can be performed while
KDPF soot accumulation pilot lamp (1) is lit.
