Operating Instructions Scarab M6
HAZARD AWARENESS
All operators and workshop personnel should be aware of the physical and biological risks that are inherent in the operation of a road sweeper. The
risk falls into two main categories as follows:
• Risks represented by the sweeper and its various systems.
• Risks represented by the sweeper's operating environment.
Both have the potential for exposure to a variety of hazards, ranging from hot surfaces to infectious diseases, that can occur during day-to-day
operation, while carrying out adjustments or when involved with the general maintenance and servicing activities on the Machine.
Typical Machine-related hazards are:
• Exposure to hot surfaces and sharp edges.
•Exposuretomovingparts.
• Exposure to various fluids (including some hot and/or pressurised).
• Exposure to surface contamination resulting from general operating conditions.
Typical environmental hazards are:
• Exposure to sharp objects (e.g. broken glass, discarded hypodermic syringes) while operating or working on the Machine.
• Exposure to various infectious diseases (e.g. Legionnaire's, Weil's, Hepatitis, Tetanus) while operating or working on the Machine.
SAFETY PRECAUTIONS
When using external equipment such as the high-pressure water lance, or when dealing with potentially hazardous situations while sweeping (e.g.
unblocking a suction nozzle), always wear the appropriate Personal Protection Equipment (PPE) and exercise extreme caution if required to handle
any of the material being swept.
Before working on the Machine, subject it to a thorough steam cleaning or high-pressure hot water wash using appropriate detergents etc.
Even after taking all reasonable steps to reduce the risk from the hazards described, always wear the appropriate Personal Protection Equipment
(PPE) when carrying out sweeping duties or when working on the Machine. This includes:
Safety Gloves (including where necessary cut-resistant knitted Kevlar).
Safety boots or shoes with protective soles and toecaps.
Eye/Face protection (including where necessary full-face mask with under-chin lip).
Earplugs or Ear defenders as appropriate

OPERATING ADVICE
Please remember, the information provided in this handbook is designed to ensure that the Scarab sweeper operates both safely and efficiently.
The design of this machine is for the removal of spoil on traffic or pedestrian areas also litter collection using the wander hose.
A poorly maintained machine will become unreliable, inefficient and potentially dangerous. Always observe the recommended maintenance and
safety related advice provided.
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 more of the finer material will pass through the screen, wearing out the fan blades on its way back to the
environment behind you.
Operators should be trained in the following elements:
• Health & safety observations/notices
• Transit driving
• In-cab & external controls
• Hopper safety/cab prop use
• Brush setting
• Nozzle flap adjustment
• Correct sweeping operations
• Low & high pressure water systems
• Load discharge (tipping)
• Daily, weekly maintenance schedules
• End of day cleaning, ie: suction fan, fan screen & Machine body
Operator training can be provided by Scarab Sweepers upon request.
The LCD monitor’s USB connection is for uploading/downloading information (ONLY) and must not be used for any other purpose.
It is the responsibility of employers to carry out they own risk assessment for the machine, operators or other persons using or affected by the
machine and equipment.
Various safety, hazard and user information labels are fixed to the machine. These must be observed.
Only personnel qualified in the relevant disciplines should be allowed to work on any of the machines HYDRAULIC SYSTEM.
For information regarding vehicle operation and maintenance, refer to the chassis manufactures handbook.

THE CANbus SYSTEM
The CANbus system comprises two control panels (main and auxiliary) an LCD monitor and a number of control nodes. The system controls and
monitors all sweeper functions and maintains a log of various operating parameters such as operating hours and any fault conditions that might occur.
Switches: The various types of switch function are grouped in two ways. Firstly they are colour coded as follows:
AMBER = Electrical functions such as lighting.
RED = Critical functions (e.g. Engage Hydrostatic Drive).
GREEN = Sweeping functions.
BLUE = Water Spray functions.
Each switch illuminates a function-related symbol on the LCD monitor (only installed equipment will be displayed). Each symbol is greyed-out until
its switch is activated. When a switch is activated the appropriate symbol will illuminate according to system status as illustrated.

OPERATING IN SWEEP MODE
REFER TO THE HEALTH & SAFETY INFORMATION ON Page 6
REDUCING NOISE LEVELS & FUEL CONSUMPTION: Although it is important to always operate within the engine’s optimum speed range, there are
times when it is possible to reduce engine speed to the lower end of this, thereby reducing noise levels. This is most beneficial when sweeping at
night, or in areas sensitive to noise pollution. Sweeping at reduced engine speeds can be achieved most satisfactorily when sweeping light or
sparsely distributed materials. Experience will enable the operator to vary engine speed, according to sweeping conditions, without affecting
sweeping performance.
It should be noted that the operator also benefits from reduced noise levels within the cab and that any reduction in engine speed, also results in
a corresponding reduction in fuel consumption.
Starting the auxiliary engine
When the Machine’s ignition is turned on the following events occur:
• The CANbus system checks that all control nodes are present and functioning correctly and the LCD Monitor turns on, briefly displaying the
Scarab logo (for approx. 12 seconds) before changing to display a basic truck graphic as well as the suction fan and auxiliary-engine speed
scales.
If a system error is detected at this stage, the ‘Fault Active’ symbol will illuminate.
To identify the error, refer to the Options Screen menus (Driver’s Fault Codes) on Page 36.
• The auxiliary engine’s pre-heating cycle will commence.
To Start the auxiliary engine, proceed as follows:
1. Press and hold down the System Start/Stop switch until the engine starts. When the engine starts, its default IDLE speed (950 RPM) will
register on the top right-hand section of the LCD monitor. With the engine running, the system is now effectively in Sweep Mode and a
number of symbols representing the installed sweeping equipment will appear superimposed on the LCD monitor truck graphic.
2. On the control panels, select the desired sweeping equipment: Refer to Page 17.
Engine speed will increase when the following functions are selected.
• Suction Fan/High Pressure Pump 1200 RPM.
• Suction Fan Boost 1700 RPM.

Suction fan boost setting
When required a boost setting is available for the suction fan. This increases fan speed and is used when sweeping heavy material. To operate the
fan at the Boost setting, carry out the following procedure:
1. With the suction fan running press the BOOST switch . Refer to Page 12.
Sweeping
1. Switch on the hazard warning beacons.
2. Switch on the suction fan . The suction fan symbol on the LCD Monitor will change from WHITE to GREEN.
3. Select the desired configuration of brushes/suction boxes and water sprays (any combination of brushes and water can be selected) either
manually or by pressing the Favourite Settings switch to recall your preferred arrangement. Switch on work-lights as required.
4. Move the Multi-Function Switch (located on the auxiliary control panel) to the ‘Sweep Master Switch ON’ position to start and
deploy the pre-selected sweeping equipment.
To stop and stow the sweep gear, return the switch to OFF. The sweeping equipment will raise to the stowed position and all
water spray jets will stop (this will also occur automatically as soon as REVERSE is engaged, reverting to the original configuration
as soon as REVERSE is disengaged).
5. Operate the multi-function switch to swing the side brushes OUT and the Nozzle Tilt switches (auxiliary control panel) as
required to suit the sweeping conditions. The multi-function switch can also be used to control nozzle-tilt (Refer to page
12, for operating details).
While in the ‘Sweep Master Switch ON’ position, the multi-function switch will automatically return to the central position
from the side brush and nozzle control positions.
6. Select the forward ratio best suited to the prevailing sweeping conditions and commence sweeping.
If considered appropriate reduce/increase auxiliary engine speed to suit the prevailing sweeping conditions, by means of the engine
