SAFETY MESSAGES
There are several specific safety messages on this
machine. The exact location of the hazards and
description of the hazards are reviewed in this
section. All personnel working on or operating the
machine must become familiarized with all the
safety messages.
Make sure that all of the safety messages are
legible. Clean the safety messages or replace the
safety messages if you cannot read the words.
Replace the illustrations if the illustrations are not
legible. When you clean the safety messages, use a
cloth, water and soap. Do not use solvent, gasoline
or other harsh chemicals to clean the safety
messages. Solvents, gasoline or harsh chemicals
could loosen the adhesive that secures the safety
messages. Loose adhesive will allow the safety

WATER TANK (MTT)
The MEGA steel water tank consists of a water
tunnel, primary floor, vertical baffles, bulkheads,
outer skins, internal piping and external piping.
The tank design is patented and known as the
Mega Anti-surge Stabilization System (MASS).
The tank structure is built around and on top of the
tunnel super structure. The tunnel provides
support to the floor plate, pivot structure, baffles
and mounting for the water pump. The floor plates
carries loads while the baffles and bulkheads add
to tank strength and dampen water surges.
External and internal piping is also used to carry
water from the water pump to spray heads, water
cannon, spray bar, hose reel, dump bar and tank
drain.
WATER PUMPS
The unit is configured with different types of water
pumps depending on tank capacity and customer
specifications. These water pumps are very similar
in design. For the purposes of this manual, the M-4
Pump (6 inch inlet & 4 inch outlet) is used to
present component information. The unit may
instead be equipped with an M-4B Pump or a
Berkeley Pump.
M-4 Water Pump
M-4 Water Pump Major Components and
Functions
1. BRACKET – Main frame of the pump that allows a
pump to be bolted to the tanker and provides
the means to direct mount the hydraulic drive
motor.
2. VOLUTE CASE – A “snail shell” shaped case that
encloses the impeller. It is narrow at the center
and enlarges from there to the discharge area.
3. WEAR RING – Acts as a bearing surface between
the impeller and volute case. Constructed of
bronze material.
4. IMPELLER – Rotating wheel attached to the shaft
that accelerates the speed of the water
producing water flow and pressure.
5. SHAFT SEAL – Confines grease to the inner and
outer bearing area while keeping foreign
material from entering the bearing area and
seals water inside the volute case.

6. ROPE SEAL – Provides a seal around the rotating
pump shaft at the volute case. Constructed of
a graphite rope material that is designed to
drip water and allow shaft lubrication.

for the pump shaft.
HYDRAULIC DRIVE MOTOR
M-4 Pump Drive Motor And Cross-over
Assembly
The M-4 pump rotates clockwise as viewed from
the drive end of the assembly:
The hydraulic drive motor may be installed in 4
different orientations depending on the water
pump location or application.
Hydraulic Drive Motor Port Identification
The hydraulic drive motor requires hydraulic flow
from a valve to the motor pressure port, return oil
flow to the hydraulic reservoir and a free to tank
case drain.

Hydraulic Drive Motor Speed Control
(Crossover Assembly)
The hydraulic drive motor speed control
(Crossover Assembly) consists of a flow control
valve, 2 hydraulic manifolds, crossover hose and
test ports.
Hydraulic Flow Control Valve
The hydraulic flow control is directional. The arrow
on the body indicates the direction of oil flow to
meter the bypassing oil. The adjusting knob on the
valve will allow adjustment of the oil flow to
bypass the drive motor, up to135 LPM (35 GPM) or
up to 700 RPMs (RPM increase/decrease will vary
depending on the size of hydraulic drive motor the
unit is equipped with).
If the flow control is reversed, the flow control
adjusting knob will not function and the full flow
capacity of the valve will bypass. This can result in
water pump rpm being below specifications with
no adjustment capability of the adjusting knob.
By turning the adjusting knob clockwise, the
hydraulic oil that is bypassing will be reduced,
increasing the speed of the water pump. Turning
the knob counter-clockwise will increase the
volume oil being bypassed reducing the water
pump speed. The flow control valve is typically
mounted on the PRESSURE manifold of the
hydraulic drive motor.
Hydraulic Drive Motor Activation
The hydraulic drive motor on MTT’s are typically
driven by the chassis hoist hydraulic system. The
activation can be controlled by the following:
– Existing Electric Hoist Valve
The MEGA cab control pump switch commands
the hoist valve to operate by sending an electric
signal to the electric solenoid on the hoist valve.
This operates the hoist valve, diverting the
hydraulic oil to the water pump drive motor.
– Pilot Operated Diversion Valve
A remote mounted diversion valve that receives
an electric signal from the cab control pump
switch to activate a pilot control to move a
spool within the diversion valve redirecting the
hydraulic oil to flow to the water pump drive
motor. Typically this type of valve is installed
between the hoist pump and the hoist valve.
– Existing Mechanically Operated Hoist Valve
Typically used on early model trucks with a
pneumatic system. This system is operated by
the cab control pump switch sending an electric
signal to an electric/pneumatic solenoid to
control a pneumatic cylinder. When the
pneumatic cylinder operates it moves the spool
valve of the hoist valve to divert hydraulic oil to
the water pump drive motor.

CAB CONTROL SYSTEM (ANALOG)
Multi-function control box that is mounted in the
vehicle cab to control all water tank functions.
Controls are available for the water cannon,
intermittent spray, water pump, work lights, foam
suppression, adjustable nozzle, system, spray
heads, spray bar, gravity dump bar and tank drain
valve. The control box also provides indications of
tanker water level and a system fuse holder. The
cab controls requires 24 VDC vehicle power to
operate.
The control box and joystick have a modular
design, which allows the joystick to be detached
from its holding bracket and operated separately
as needed. Older hydraulic control boxes do not
have this functionality, but they can be upgraded
to the latest design by MEGA.
The control functions operate as follows:
Control Function
Joystick Sends command signals to the
logic box (electric water
cannon) or hydraulic control
valve assembly (hydraulic water
cannon) to move the water
cannon left, right, up and down.
FOAM Open or closes the foam
concentrate tank in-line control
valve.
FOG On adjustable nozzle water
cannons, adjusts cannon for less
concentrated flow (HOLD for
adjustment)
STREAM On adjustable nozzle water
cannons, adjusts cannon for
more concentrated flow (HOLD
for adjustment)
TIMER OFF Sets OFF time (variable
adjustment 5-100 sec) between
timer cycles of selected spray
heads and dump bar when the
timer switch is in the
intermittent position.
TIMER ON Sets ON time (variable
adjustment 5-100 sec) of
selected spray heads and dump
bar when the timer switch is in
the intermittent position
PUMP Routes vehicle hydraulic system
pressure and flow to the water
pump hydraulic drive motor.
MONITOR Opens the water cannon BFV.
LIGHTS Provides power to work lights.
TIMER Activates or deactivates system
timer function.
DRAIN Opens or closes tank drain BFV.

Features
GPS
Distance and speed based
operation modes utilize a GPS
based speed signal to
automatically stop/start water
flow as the vehicle moves.
Manual Spraying
With manual spraying the
operator can select each spray
head independently and can
be used without GPS
connection.
Time Based Spraying (Banding)
Operator can cycle on/off
periods of spray using selected
time intervals.
Distance Based Spraying (Checkerboard)
Alternating intermittent
watering patterns reduces
water consumption and
ensures one steering tire and
one drive tire remain on a dry
surface.
Speed Based Spraying (Continuous Rate)
Sequence-based intermittent
spray system operation uses
PWM (Pulse Width Modulation)
to vary the amount of water
flow while maintaining a
continuous rate of water
application, dependent on speed of travel.
Operation
Start-Up
When the prime mover has the key switch first
turned ON, the system performs a self test and will
flash all of the switch pad lights RED four (4) times
and turn OFF.
If the switch pads have any buttons that do not
light or the flash sequence is different, contact
your service department for repair.
