DPF Regeneration Switch (Tier 4 Engines
Only)
The Engine DPF (Diesel Particulate Filter) Switch (9)
(Figure 3-4) is located on the right side of the overhead
control panel. This switch is a three position switch, Inhibit
Regen/Permit Regen/Start Regen. Press this switch to start
engine regeneration or to disable regeneration:
• Start Regeneration
(7649-10)
• Inhibit Regeneration (7649-11)
To manually regenerate, set the crane parking brake, the
crane transmission must be in neutral and have all pedals
released.
Set up a safe area around the crane’s exhaust; remove tools,
rags, grease or any debris from the engine exhaust area. As
a warning, the light (1, Figure 3-5) below the exhaust pipe (2,
Figure 3-5) will flash during regeneration.
With the engine idling push the DPF Regen Switch (9) to
initiate regeneration.
Within 5 seconds the engine should rev up to 1000 to 1400
rpm. The engine will continue to run at this speed for up to 45
minutes.
Pressing the brake or throttle pedal during regeneration or
activating the Inhibit Regen Switch will interrupt the
regeneration process.
Make sure the crane and surrounding area are monitored
during manual regeneration. If any unsafe condition occurs,
shut off the engine immediately.
During this period the sound of the engine may change.
When regeneration is complete the engine will return to its
normal idle speed.
WARNING
Fire or Burn Hazard!
During the regeneration process the exhaust becomes
very hot. Do not park the vehicle near flammable objects.
Use caution near the exhaust tailpipe during regeneration
as it will become very hot.
CAUTION
Avoid Crane Damage!
Do not engage the park brake while the vehicle is moving.
Damage to the crane can occur.
Disengage the park brake before driving. Damage to the
crane can occur.
