NOTE
If you dry clean the DPF at the prescri-
bed interval, the
cleaning must follow
that same interval. Do not switch the
service strategy from dry cleaning to
wet cleaning and vise versa. Switching
service strategies may void warranty.
1. Dry clean using DPF cleaning
machine according to the
maintenance schedule.
2. Replace filter if necessary.
If a DPF is wet cleaned, then the
maintenance intervals may be switched to
stay on the dry cleaning strategy or start
with a wet cleaning strategy. See Diesel
Particulate Filter Service Strategy on page
71.
Diesel Particulate Filter (DPF) Wet
Cleaning
DPF can be wet cleaned at a dif
ferent
interval than a dry cleaning, but do not mix
the two intervals.
A new DPF unit may be wet
cleaned instead of being dry cleaned. This
interval only applies to new DPF units. It
does not apply to a unit that has been
dry cleaned. See Diesel Particulate Filter
Service Strategy on page 71 and Diesel
Particulate Filter (DPF) Dry Cleaning on
page 71 for details before making a
decision. Please contact your authorized
dealer for clarifications.
