will notice a significant reduction in engine power. Turn
off inhibit and perform a manual regeneration cycle
immediately.
Diesel Particulate Filter (DPF) Regeneration Inhibited
When on, this light indicates that diesel particulate
filter (DPF) active regeneration has been inhibited.
A5—Diesel Particulate Filter (DPF) Switch
The CENTER position (maintained) is for normal
engine operation. In this position, regeneration
occurs automatically.
The TOP position (momentary) is for manual
regeneration. If manual regeneration is needed
as indicated by the diesel particulate filter (DPF)
regeneration light, press the top of the rocker
switch and then release it. The engine control
module (ECM) will control a manual DPF
regeneration cycle.
A manual regeneration cycle will begin only if the following
conditions exist:
• All joysticks are in the neutral position (no functions
engaged).
• The engine is at low idle.
• The accelerator pedal is not being pressed.
NOTE: A guard over the top of the rocker switch prevents
accidental manual regeneration.
It is normal for the high exhaust system
temperature light to come on during regeneration
and remain on for a short time after regeneration.
The BOTTOM position (maintained) inhibits active
regeneration. The amber DPF regeneration light will flash
and the red Engine Stop light will glow.
Use the INHIBIT position only if directed to do so by the
Manitowoc Crane Care Lattice Team or an authorized
Manitowoc Cranes technician.
NOTE: See the engine manufacturer’s manual for
additional information on regeneration and inhibit.
A6—Diesel Exhaust Fluid (DEF) Gauge and Light
This light indicates the level of the reducing agent
in the diesel exhaust fluid (DEF) tank on the left
side of the rotating bed.
The crane operator will be warned in the following manners
when the DEF tank is low:
• The DEF light (in gauge) is the first warning that the DEF
tank is low. The DEF light will glow.
• The amber Engine Warning light (on front console) is the
intermediate warning that the DEF tank needs to be
filled. The DEF light (in gauge) will also flash.
• The red Engine Stop light (on front console) is the final
warning, before inducements kick in, that the DEF tank
is low.
NOTE: Once the DEF tank is empty and a key cycle has
occurred, or after an extended idle period, engine
power will be reduced. The DEF light will flash and
the red Engine Stop light will glow steady.
Do not store DEF for long periods of time. DEF will
deteriorate relative to time and temperature. Low-
quality DEF may require the tank to be drained and
the system purged.
CAUTION
Aftertreatment System Damage!
Do not place the diesel particulate filter (DPF) switch in
the INHIBIT position unless directed to do so by a
Manitowoc Cranes or Cummins technical advisor.
If DPF regeneration is prevented for an extended period,
the DPF will be damaged and require replacement.
Inhibiting regeneration may result in a loss of engine
power or shutdown by the engine control module (ECM)
and the need to service or replace the DPF.
CAUTION
Avoid Exhaust System Damage or Engine
Shutdown!
Prolonged engine operation with regeneration inhibited
may result in damage to the DPF and loss of engine
power or engine shutdown by the engine control module
(ECM).
Use the BOTTOM position (INHIBIT) of the diesel
particulate filter (DPF) switch only for special
circumstances in which it is desirable to inhibit active
regeneration.
WARNING
Chemical Hazard!
Diesel exhaust fluid (DEF) contains urea. Avoid the
possibility of death or serious injury. Do not swallow. If
DEF is ingested, contact a physician immediately.
Do not get DEF in your eyes. In case of contact,
immediately flush eyes with large amounts of water for a
minimum of 15 minutes.
