Introduction
Purpose of this reference guide
This reference guide is designed to prepare you, as appropriate to your
role, to drive, operate and crew the Type 3 appliance in a safe and
efficient way.
This reference guide covers the basic information required to operate
this appliance. This reference guide and the associated training do not
replace specific driver, pump operator, and firefighter training.
Act
Training requirements
Before the vehicle can be operational at your station, all crew members
must:
• self-study using this reference guide
• familiarise themselves with the vehicle, as appropriate to their role
Information
• complete the Type 3 MAN NZFS T3 001 Familiarisation Checklist.
Appliance identification
Each Type 3 MAN appliance has a New Zealand Fire Service
identification number. This number is part of a sequential list (T3 001,
Official
T3 002, T3 003, etc.). It enables you to ensure this is the correct
reference guide for your specific vehicle. The identification number is
on the plate inside the driver’s door, next to the Fraser Fire and Rescue
ID.

Section 5: Driving
Electronic stability programme (ESP)
ESP is a safety system that assists the driver in critical situations, for
example:
• skidding (over steer and under steer)
• risk of overturning
Act
by
• improving the ability to control and steer the vehicle
• reducing the risk of overturning.
The ESP system includes sensors that measure the stability of the
appliance.
The ESP system is connected to the braking and engine management
systems and possesses two vehicle-stabilising sub-functions. One of Information
these is mainly active when adhesion values are low to medium, and
helps to counteract over steer and under steer. The other sub-function
mainly takes effect when adhesion is moderate to high, and reduces
the risk of overturning. The two sub-functions are linked via an
interface and operate together. The ESP check lamp on the instrument
panel screen flashes yellow when ESP is active.
Official
ESP directional stabilising
ESP keeps the vehicle stable over surfaces with low or moderate
the
adhesion, provided that the dynamic limits are not exceeded. It
counteracts the tendency to over or under steer in certain situations.
In these situations the ESP will apply the brakes to individual wheels
to correct the behaviour of the vehicle. The ABS system will ensure
wheel lock up is prevented. under
ESP to reduce the risk of overturning
This function is intended to prevent the vehicle from overturning in
certain situations (subject to being driven within the dynamic limits
imposed by the laws of physics). This function is mainly needed at
moderate to high levels of road grip.
ESP performs this function in two stages:
Released
1. The first stage reduces the vehicle’s road speed until lateral
acceleration is below the critical level at which overturning could
occur.

Type 3 MAN T3 001- Reference Guide
2. In the second stage, any wheel which leaves the road surface on
the vehicle is detected. If a vehicle wheel lifts away from the road
surface, the second ESP stage applies all the vehicle’s brakes. The
ABS system will ensure wheel lock up is prevented.

is full.
Act
The suction relief valves (one each side of the vehicle) are preset to
1150 kPa. They are designed to protect the supply line into the pump.
The suction relief valves are fitted between the collector head and the
intake valve. In the event of high intake pressure, the relief valve opens
and the excess water dumps to ground below the pump panel on each
side.
The high pressure pump has a preset (kunkle) pressure relief valve,
which has been set to 4200 kPa. When this valve opens; the water
goes to ground under the nearside pump step.
Information
The main pump is fitted with a Total Pressure Master (TPM) discharge

Hosereels
Two Fraser Fire and Rescue hose reels are mounted on top of the
pump module. Each is fitted with 92 metres of Boston booster hose
and TFT ULTIMATIC 125, 500 kPa model BL-BGH branches, and each
hose reel is fitted with power and manual rewind systems. Circuit
Breakers are fitted to the nearside pump panel. A water shutoff valve
is positioned on the main pump panel.
Act
A friction brake is fitted to each hose reel. In the event of a power
failure, the hose can be rewound manually. To rewind the hose, insert
the supplied handle through the front of the hose reel bollard onto the
bevel gear shaft. Then push to engage the manual rewind gear with

Section 7: Foam system
Foam Pro system
The foam system is a Foam Pro 2002 direct injection with a 53 litre
plastic tank and on-board foam refill pump.
Foam is available from both the nearside delivery outlets, both hose
reels, and the deck monitor.
The waterway is configured to deliver water only, from both offside
Act
delivery outlets.
The Foam Pro system is an electrically driven, flow-based
proportioning system that measures water flow and injects a
proportional amount of foam concentrate into the discharge side of the
pumps.
The foam system is designed for Class A foam only.
The foam proportioning and multi-flow gauges are mounted to the right
of the Foam Injector Selection switch.

Released
Upon receiving your new Type 3 appliance, the foam concentrate
system will need to be charged. To do this:
1. Fill the foam tank with Class A foam.
2. Turn the foam system on by pressing the red FOAM button and set
it to normal pressure.
3. Set the foam percentage to 10% by pressing the SELECT button
until the indicator is beneath “ % ”, then use the UP arrow to
increase the rate to 10%.

4. Open a foam capable low-pressure delivery outlet and run the main
pump up to approx 150 L/min until foam is present.
5. Switch the foam system to high pressure and run a hosereel
at something close to its normal maximum output until foam is
present.
6. Close down and flush the water pump waterway as usual.

7. Set the foam pump proportioner back to the normal operating
percentage. (Note: the lower the main water pump pressure the
faster the prime. Therefore do not fit a nozzle to the delivery outlet
being used).
Contents level
The foam concentrate contents gauge is mounted on the left side of
the pump panel next to the Foam Injector Selection switch.
Information
When the foam level drops to 1/8, the LED lights on the contents
gauge will begin to flash to alert the pump operator.

High / Low flow warning
Act
If the foam concentrate pump cannot supply the correct proportion of
foam it will display a warning on the foam control display.
“Lo.Flo” means there is so little water flowing that the foam system
cannot accurately supply such a small quantity of foam concentrate.
“Hi.Flo” means that there is so much water flowing that the foam pump
cannot supply enough foam concentrate to maintain the selected
concentration.

portable base
The monitor unit mounted in the pump frame, is a TFT 18” Extend-a-
gun with a crossfire monitor, and is fitted with a Master Stream 150-
1250 nozzle. Operation of the monitor is from the body roof platform
position. The waterway open/close switch is mounted on the monitor
support tube. It will not operate until the monitor is fully extended.
Act
There is a warning light in the cab, which comes on when the monitor
is extended.
The monitor can be ground mounted, by using the Safe-Tak 1250
portable base. To ground mount:
1. Position the monitor over the base.
2. Slide it onto the portable base until the pawls engage.
Ladders
Information
The appliance is fitted with three ladders:
• a 10.5 m rescue ladder (a 464 Rescue Ladder can be fitted)
• two access ladders.
Official
Rescue ladder is mounted on a fixed beam gantry on the top deck of
the appliance. Two access ladders are stowed in the rear locker.
To remove the rescue ladder, lift the manual release arm only when the

When housing the rescue ladder, ensure the head of the ladder is kept
up off the gantry, and the weight of the ladder is taken by the rollers at
the base of the gantry. Once the ladder gets beyond the tipping point
