Question 12

DEF Tank

Answer 12

4.5 Gallon DEF tank

Question 13

High Exhaust System Temperature

Answer 13

The HEST light illuminates when exhaust is over
977°

Question 14

DEF Indicator Light

Answer 14

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.

Question 15

Warm Water Decon System

Answer 15

• 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.

Question 16

Onspot automatic
chains Operation

Answer 16

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.

Question 17

Ladder Rack

Answer 17

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

Question 18

Cavitation Protection

Answer 18

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.

Question 19

Pressure correction

Answer 19

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.

Question 20

Intake Relief Valves

Answer 20

will be left preset at
190.
– May cause vacuum leak when
drafting.

Question 21

Booster Reel

Answer 21

Located on Driver’s side
pump panel.
* 200’ of 1” hose.
* Very high friction loss
and designed for lower
flows (up to 60 GPM).
* Friction loss for 30gpm
is 37 psi per 50’
section.

Question 22

Foam System

Answer 22

• Foam is plumbed to all crosslays, and
  the hose reel.
• System automatically injects correct
  amount of foam to match flow.
• Preset at 0.4% for Class B fires.
  Reduce to 0.1% for Class A fires.
• Can flow 3,000 gpm at 0.4%.
• 20-gallon tank 7,500 gallons of
  solution at 0.4%.
