Automatic Active Regeneration
While Driving or Pumping

A

The
following vehicle conditions must be met:
* Sufficient accumulation of soot in the filter.
* Sufficient exhaust flow and temperature
conditions (typical pumping or driving).
* Speedometer showing 5 mph or higher vehicle
speed.
There is no need to inhibit regeneration during

Parked Regen

A

When needed, (DPF Light On)

Park apparatus outside, safely off roadway, on
clean/clear surface that will not melt (not asphalt!)
with minimum 5 ft. clearance around exhaust and
away from people, or any flammable materials or
structures. Exhaust temperatures during a normal
regeneration event can get up to 1500 °F.
Caution: Do not place ladders near exhaust

Q

Stationary Active Regeneration

A

Park Brake must be set, Transmission must be
in Neutral, Accelerator, and foot brake pedals
must not be pressed, Apparatus and pump
governor at idle.
* With Engine parked and running at idle, press
and hold ‘DPF REGEN’ switch for 5 seconds.
(DPF light must be illuminated to initiate parked regen)

25
Q

High Exhaust System Temperature

A

The HEST light illuminates when exhaust is over
977°

26
Q

Parked Regen

A

Once the parked regen has completed, 20-40
minutes, engine will return to normal idle speed
and operation.
- HEST light will remain illuminated until the
exhaust temp drops back to normal (or vehicle
speed exceeds 5 mph).
- All other indicator lights should turn off.
- If DPF light remains on, attempt another regen.
- If DPF light remains on after 2nd regen, or if ‘Check
Engine’, ‘Stop Engine’ or ‘MIL’ light remain on, take
out of service.

27
Q

Cancelling a Parked Regen

A

If it’s necessary to cancel a parked regen (such as
the need to respond to a call), the driver can press
the ‘REGEN INHIBIT’ switch. The engine should
return to idle.
Stepping on the throttle, releasing the parking
brake, putting the transmission in gear, or turning
the ignition off, will also cancel a parked regen.

28
Q

Check Engine Light

A

Engine may have exceeded limits, the ECU
may have found a fault – check gauges.
Contact apparatus maintenance.

29
Q

Stop Engine Light

A

Indicates a major engine fault, serious damage
may result. Move to nearest safe location,
shut down and taken out of service.

30
Q

Malfunction Indicator Light (MIL),

A

Malfunction Indicator Light (MIL), indicates a
fault of an emission related component.
Contact apparatus maintenance.

31
Q

Diesel Particulate Filter (DPF)
Light Solid

A

Light is on Solid (not Flashing)
Vehicle requires regen in reasonable
amount of time.
* Initiate an active regen with
highway driving or pumping
conditions
* OR perform a parked regen
Note: The apparatus can remain in
service during a parked regen.

32
Q

Diesel Particulate Filter (DPF)
Light Flashing

A

Light is Flashing
Vehicle requires regen as soon as
possible.
* Initiate an active regen with
highway driving or pumping
conditions
* OR perform a parked regen
* One or the other should be done as
soon as possible

33
Q

Diesel Particulate Filter (DPF)
Light With Check Engine

A

Parked regen must be performed. If
DPF light remains on after parked
regen, repeat. If light remains on
after 2nd regen, take out of service.

34
Q

Diesel Particulate Filter (DPF)
Light With Stop Engine

A

Vehicle should immediately be
moved to nearest safe location, shut
down and taken out of service.
Serious engine damage may result if
driven. Contact apparatus
maintenance.

35
Q

High Exhaust Temperature
System (HEST) Light

A

Indicates that an Active Regen has
been initiated and exhaust temp is
elevated above normal levels.
Only occurs when vehicle is
stationary or moving less than about
five mph.

36
Q

DEF Indicator Light

A

SOLID – Between 1/4 and 1/8 full
* FLASHING – Below 1/8 full

If the DEF indicator light and any
or all of these additional indicators
come on, the DEF tank is below
1/4 gallon, and should be refilled
immediately.

37
Q

Fan Engagement

A

The fan clutch will engage to provide
airflow to cool the engine when one or more
of the following conditions are met:
– The engine coolant or air intake temperature
reaches the engine manufacturer’s preset
temperature for fan engagement (220 F).
– Placing the truck in “pump gear”.

38
Q

Shoreline Plug

A

In addition to charging the
apparatus batteries:
– Powers the receptacle in the L-3
compartment to charge the Blow
Hard Fan located in the rear
compartment. It also powers the
E-draulics and Hilti battery
chargers located in L-3.
– Powers the water heater for the
decontamination rinse system.
* If the station GFI breaker trips, turn
off the power to the water rinse
system 120 volt heating element.

39
Q

Warm Water Decon System

A
  • Separate 18-gallon water tank. Located above
    Cross lay compartment.
  • Two water heaters, 12v & 120v.
  • Designed to keep water tank warm 24/7 and
    ready for use immediately.
  • Full tank of cold water takes approximately 45-
    60 minutes to fully warm on shore power.
40
Q

Electronic Transmission Fluid Check

A

The fluid temperature is
above 140 F, and below 220
F.
* The transmission is in
Neutral.
* The engine is at idle.
* The transmission output
shaft is stopped.
* The vehicle has been
stationary for approximately
two minutes to allow the
fluid to settle.

41
Q

Antilock Braking System

A

– ABS also allows for Anti-Slip-Resistance (ASR) feature.
If one wheel is off the road, spinning, ASR will apply
that brake to increase torque to the other wheel,
allowing it to pull the apparatus out.
– If both wheels are spinning, ASR will reduce the
engine torque to match the conditions.
– ASR is completely automatic, the driver does not need
to do anything.

42
Q

ASR

A

Sometimes, you may not want the ASR to
work at 100%, such as when trying to climb
out of deep mud or snow, loose dirt or sand.
– In that case, press the Off Road Traction Control
switch. This will allow some slippage (spinning) to
assist in climbing out.
– Press again to turn off. It will also reset with the
ignition switch cycling.

43
Q

Stability Control

A

Roll stability control (RSC) senses when a rollover may
occur and intervenes by reducing throttle, application
of the retarder, and/or selective brakes.
– Electronic Stability Control (ESC) compares where you
are steering and where you are actually going
(skidding) and tries to correct by selectively applying
the brakes and throttle/transmission.
* The driver still needs to provide steering input.

44
Q

Onspot automatic
chains

A

Onspot automatic
chains are on the rear
inside duals.
* Effective up to about
four inches. Advantage
is ability to turn on for
snowy or icy roads and
off for clear roads.

45
Q

Onspot automatic
chains Operation

A

Engage when traveling between 2-25 mph just
before reaching slippery conditions.
– Do not exceed 35 mph.
– Can stop on chains and start again, as long as
switch is still in the active position.

46
Q

Command Zone

A

The Command Zone system is a control and monitoring device for the
apparatus multiplex system. The Command Zone system
communicates with assigned components of the apparatus to inform
the operator of current status of those components.

47
Q

Ladder Rack

A

The Extension Ladder is Now a 28’ 2 section ladder, it weighs 87
lbs. Compared to a 35’ 3 section weighing 129 lbs.

48
Q

To Activate Pump –

A

Stop, Shift, set the
brake (setting the Brake automatically shift
trans to neutral), Engage pump switch and
wait for the OK to Stationary Pump.

49
Q

To Pump and Roll -

A

Stop, set the brake,
Engage pump switch, Set up the pump for
desired discharge, Release Brake and wait
for the OK to Pump and Roll. Only use 1st
gear for Pump and Roll.

50
Q

Preset

A

125 psi. Or, 1000 RPM
depending on mode

51
Q

Cavitation Protection

A

If PSG cannot recover, it switches to RPM Limit Mode.
* Pressure LED stays on.
* Displays flash and states Operator / RPM Limit.
* Pressure Setting Does not change, but Preset is disabled.
* PSG acts like manual throttle.
* If pressure recovers or operator corrects, returns to Pressure
Control Mode – normal operation.
* If it does not recover but stays above 45 psi, remains in RPM
Limit Mode.

If pressure falls below 45 psi, but above 15 psi, enters
Lo Water Mode
– Displays Lo Water
– Sets rpm at 1100
– After seven seconds goes to idle.
* If pressure falls below 15 psi, enters No Water Mode
– Displays No Water
– Goes to idle.

52
Q

Pressure correction

A

In the RPM Limit, Lo Water, No Water Modes,
if the pressure recovers, it goes back to
Pressure Control. If the operator intervenes
and brings the RPMs to a point where it is not
in cavitation, it goes back to the Pressure
Control Mode.
* If it goes to idle and stays more than 3
minutes, it enters the Idle mode and cancels
the pressure setting.

53
Q

Priming

A

Normally left in Auto.
– Priming will start when in pump gear,
and shut off when primed (20 psi).
– If loss of prime while operating, will automatically
Re-Prime.
