DPF Level 1: The DPF is loaded with soot and
needs to be regenerated. When safe, please uninhibit
automatic active regeneration.
DPF Level 2: The soot level has continued to
accumulate. Increase engine RPMs (if at idle) and
engine load to prompt automatic regeneration.
NOTE: If the operator is inhibiting automatic
regeneration and does not perform parked
regeneration, the soot level will continue to
rise.
DPF Level 3: An orange message alert banner
may appear to warn the operator that soot levels are
extremely high. (Figure 4-36) If you have allowed
the exhaust soot level to reach Level 3, automatic
regeneration is not possible. If this message appears,
the operator must perform parked regeneration at the
earliest opportunity. When safe, complete a parked
regeneration as described on Pages 4-32 and 4-33.
Continued operation without
completing a parked regeneration can cause engine
damage and will void engine warranty. The operator
should perform parked regeneration immediately!

DPF Level 4: If the operator continues ignoring DPF
level warnings and the soot level reaches Level 4, a red
message alert banner appears on the engine and pave
screens. (Figure 4-37)
Engine output is limited and the operator can no longer
perform regeneration. Regeneration is required
IMMEDIATELY by a qualied engine or OEM service
technician using specialized equipment. Move the
paver to a safe location, shut down, and contact your
authorized dealer for service.
If the soot level reaches Level 4 or
5, specialized equipment is needed to perform
regeneration and the machine must be serviced
by your authorized dealer. The DPF system may
become damaged and require replacement.
Therefore, performing regeneration BEFORE
reaching Level 4 is imperative for preventing costly
repair.
