OPERATING ADVICE
Please remember, the information provided in this handbook is designed to ensure
that the Scarab sweeper operates both safely and efficiently.
A poorly maintained machine will become unreliable, inefficient and potentially
dangerous. Always observe the recommended maintenance and safety related
advice provided.
Many supposed operating problems can be traced to a lack of simple daily
maintenance. Going out to sweep in a machine that has blocked screens, a dirt
encrusted suction fan, poorly adjusted suction nozzles or brushes is not only a waste
of time; it is also a waste of fuel.
Unless it is wet or raining, ALWAYS use the low-pressure water spray system when
sweeping. This will not only reduce the amount of dust generated, it will also ensure
more efficient collection of material. This is because wet material is heavier and will
drop more readily from the air stream inside the hopper. If swept dry most of the
finer material will pass through the screens, wearing out the fan blades on its way
back to the environment behind you.

THE CANbus SYSTEM
The CANbus Sweeper Control System comprises a control panel and three
control nodes. The system controls and monitors all sweeper functions. The
main panel contains a CPU which holds all the program information and
also logs operating system errors. This greatly simplifies the process of
identifying and curing operating faults. The control nodes are located
adjacent to the sub-systems they control. The CANbus control panels use
touch switches; these are covered by a flexible overlay to identify their
functions. The various types of switch function are grouped in two ways.

SCARAB M6 SWEEPER KIT
7 Operator’s Manual Amdt.1 - 03 November 2009
Firstly they are colour coded as follows:
ORANGE =Electrical functions such as lighting.
RED =Critical functions (e.g. Auxiliary Engine).
PALE GREEN =Sweeping functions.
BLUE =W
aterSprayfunctions.
Secondly, switches that control functions that are available on both sides
of the machine, e.g. side brushes, are grouped with left, right and centre
function controls being positioned accordingly on the panel.
Each switch has a red LED located at its upper left hand corner. This
illuminates when the switch is ON (latched) or PRESSED (non-latching).
Most switches are of the latching type (press once to turn ON and again
to turn OFF) however there are a number of non-latching switches. These
will only function while they are held down and are as follows:
Auxiliary Engine START
Auxiliary Engine STOP
Nozzle Tilt (Momentary)
Apart from switches for the sweeping equipment, the main panel also
incorporates an LCD screen and a light-sensor. The LCD provides real-time
information relevant to the operating status of the machine, in the form of
warnings or feed-back, and acts as the inter-face when using the self-
diagnostic facility. The light-sensor automatically controls the panel/LCD
back-lighting to ensure legibility in low ambient light conditions.
MAIN PANEL SWITCH DESCRIPTIONS
Switch functions are described from Left to Right and Top to Bottom.
MASTER SWEEP
Switches that are fully enabled ONLY when the Master Switch is
ON or Sweep Mode is ON are identified by the following symbols.
Switch functions are described Left to Right Top to Bottom.
PANEL STAND-BY MODE / SWEEP MODE SWITCH - Press to turn the sweeper
panel ON or OFF. Red LED illuminates when sweep mode is selected.
BEACON SWITCH -Press to operate hazard beacons (cab beacon may
have a separate switch on some chassis). Red LED illuminates when
active.
MANUAL PRE-HEATERS SWITCH -Press to operate the auxiliary engine
heaters. Red LED illuminates when heating cycle is complete,
accompanied by a beep.

REFER TO THE HEALTH & SAFETY INFORMATION ON Page 3
STARTING THE AUXILIARY ENGINE
ALWAYS ensure that the control panel is OFF before starting the auxiliary engine.
When the vehicle’s ignition is turned on the following events occur:
CANbus runs a number of system checks to confirm that all the control
nodes are present and functioning correctly. The result of this check
can be seen briefly in the form of an appropriate number of ‘+’ or ‘–’
symbols that appear along the lower display line on the LCD screen. A
‘+’ symbol indicates that a node has passed and a ‘–’ symbol
indicates that a node has failed to respond as expected.
Consequently, a display line such as ‘+ + –’ would indicate that node 3
has failed (if a failure occurs, report the event to your supervisor). The
LCD then displays the following auxiliary engine status information:
• Top Line Alternates - Engine Speed.
• Bottom Line - Water Temp.
The auxiliary engine pre-heating cycle starts automatically. The red
LED on the HEATERS switch will illuminate briefly accompanied by and
audible ‘beep’ to denote that the heating cycle is complete.
If the vehicle has been driven to the work site immediately prior to sweeping,
without the auxiliary engine operating, it will be necessary to start the pre-
heaters manually (Step 1) otherwise go to STEP 2.

SCARAB M6 SWEEPER KIT
13 Operator’s Manual Amdt.1 - 03 November 2009
1. Press the PRE-HEATERS switch. After a brief delay the red LED will
illuminate briefly accompanied by and audible ‘beep’ to denote
that the heating cycle is complete.
2. Press and hold the engine START switch until the engine starts. As
soon as the engine is at IDLE speed (approx. 1000 rpm), the START
switch is disabled (backlight OFF) and the engine STOP switch is
enabled (backlight ON).
ACTIVATING THE CONTROL PANEL
1. Press the stand-by/sweep mode switch to activate the
sweeper controls. The red LED will illuminate to confirm that
the panel is active. At the same time, the backlights for all
available services will illuminate. Red LEDs will illuminate on any
active switches (i.e. sweeping equipment remaining selected from
previous sweeping duties). Preselected equipment will not deploy/
start until the Sweep Master switch is activated).
The LCD display changes as follows:
• Top line - Engine Speed (Auxiliary).
• Bottom line alternates - Water Temp/Active Warnings
SWEEPING
1. With the chassis and auxiliary engines running and control
panel ON, switch on the suction fan. The auxiliary engine will
automatically increase speed to its default operating speed
of 1600 rpm.
2. Select the desired sweeper configuration (any combination of the
available sweeper functions can be selected). Switch on the
beacons and work-lights as required.
3. Press the Sweep Master switch ON to lower and start the
selected sweeping equipment. All sweeping equipment
will stop and rise to the stowed position when the switch is
pressed a second time. This will also occur when REVERSE
gear is engaged.
4. Operate the side brush IN/OUT and nozzle TILT switches as required
to suit the sweeping conditions.
5. Select an appropriate forward gear ratio to suit the prevailing
sweeping conditions, release the parking brake and commence
sweeping.
REVERTING TO NORMAL DRIVE MODE 1
The vehicle can, if required, be returned to normal drive mode without
stopping the auxiliary engine. This is useful where a temporary pause in
sweeping is required such as when traversing a busy road junction or
when it is known that you will be resuming sweep mode within a short
distance beyond an obstacle. In this event proceed as follows at the
end of the sweeping run:

SCARAB M6 SWEEPER KIT
Amdt.1 - 03 November 2009 Operator’s Manual 14
1. Press the Sweep Master switch OFF to stop and raise all
active sweep gear. The Sweep Master LED will extinguish.
2. Press the panel ON/STAND-BY switch to turn off the control
panel. This will allow the auxiliary engine to revert to IDLE.
3. If appropriate, switch off the work lights and beacons.
The vehicle can now be moved through the junction or
obstacle to the next sweeping site.
REVERTING TO NORMAL DRIVE MODE 2
If the vehicle is being returned to normal drive mode for a period of time
sufficient to warrant stopping the auxiliary engine, or it is intended to
stop the vehicle, proceed as follows:
1. Press the Master switch OFF to stop and raise all active sweeping
equipment. The Sweep Master LED will extinguish.
Cancel all active sweeping equipment by pressing all switches that are
illuminated by a red LED before switching off the panel.
2. Press the panel ON/STAND-BY switch to turn off the panel.
This will allow the auxiliary engine to revert to IDLE.
Before stopping the auxiliary engine allow it to run at IDLE speed for at least
two minutes to allow the turbo-charger to cool. Failure to comply will result
in premature failure of the turbo-charger bearings/oil seals.
If stopping the vehicle at the end of a sweeping run DO NOT remove the ignition key
until the auxiliary engine has had sufficient IDLING time as removing the key will
close-down the CANbus panel, stopping the auxiliary engine.
The LCD screen will continue to display information relevant to the sweepers
operating mode even when the panel is not active.

HOPPER DISCHARGING PROCEDURE (TIPPING)
The hopper and rear door control levers are sited externally on the
sweeper sub-frame adjacent to the nearside suction nozzle.
BEFORE OPERATING THE DOOR OR HOPPER ENSURE THAT ALL PERSONNEL ARE
CLEAR OF THE IMMEDIATE AREA.
Ensure that the suction fan is turned OFF and there is room for the door to open fully.
Always ensure that door is OPEN before raising the hopper. This will avoid the
possibility of causing damage to the door in the event of a heavy load sliding back
as the hopper tilts
The auxiliary engine must be running for the rear door and hopper tilt controls
to function.
1. Push the rear door control lever away from you and hold it in this
position until the door is fully open.
2. Operate the manual dump-valve controller as illustrated, holding it
in position while operating the hopper control lever.
3. Push the hopper control lever away from you and hold it in this
position until the hopper is in the fully raised position. The hopper
safety prop will automatically deploy during this step.
BEFORE LOWERING THE HOPPER, ENSURE THAT THE AREA BELOW IT IS CLEAR.
4. Move the hopper prop lever as illustrated to engage with the prop
and reposition it clear of the hopper.
5. Operate the manual dump-valve controller as illustrated, holding it
and the prop lever in position while operating the hopper control
lever.
6. Keeping the prop in the upright position, operate the hopper
control lever by pulling it towards you and hold it in this position until
the hopper is fully lowered.
Before closing the door, ensure that the seal, and mating faces on the hopper, are
free from any foreign matter that might damage the seal or adversely affect the
sealing function.
7. Operate the door control lever by pulling it towards you and hold it
in this position until the door is fully closed (door indicator in the
closed position). Ensure that the door catches have engaged fully
before releasing the lever.

USING THE AUXILIARY HYDRAULIC PUMP
In the event of hydraulic failure in
powered mode, an auxiliary hydraulic
pump is fitted, to enable the raer door and
hopper to be operated manually. This is
located on the same side of the vehicle
and adjacent to the hopper and door
control levers. The pump handle is stowed
in the cab.
It should be noted that it will require a
substantial number of pumping cycles to
complete the following procedures.
Insert the auxiliary pump handle, holding
the appropriate lever in the correct
position, proceed to move the handle, in
an up and down movement.
The auxiliary hand pump operates the
hopper and rear door in both directions

USING THE REAR-MOUNTED WANDER BOOM
The rear-mounted wander boom arrangement is permanently fitted and,
when required, can be used while sweeping. The weight of the hose/
nozzle is supported by a gas strut attached to the boom assembly. The
system incorporates a manually operated blanking flap.
For situations requiring maximum suction power, such as when clearing gully
pots, blank off the suction nozzles (See Para. 1.).
1. Deselect any active suction nozzle(s). This will close their
nozzle blanking flap(s). The switch LED will extinguish.
2. Demount the hose assembly from its stowage as detailed at
Fig. 6 and swing-out the entire assembly to the required position.
3. Open the blanking flap. The wander boom is now ready for use.
