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

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.
