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 risks fall
into two main categories as follows:-
• Risks represented by the machine 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 in the general maintenance and servicing activities on the machine.
Typical machine related hazards are as follows:-
• Exposure to hot surfaces and sharp edges.
• Exposure to moving parts.
• Exposure to various fluids, including some that are hot and/or pressurised.
• Exposure to surface contamination resulting from general operating conditions.
Typical environmental hazards are as follows:-
• Exposure to sharp objects, e.g. broken glass, discarded hypodermic syringes/needles, while operating or working on the machine.
• Exposure to various infectious diseases, e.g. Legionnaire’s, Leptospirosis, 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 personnel protective 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 of 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 personnel protective equipment (PPE) when
carrying out sweeping duties or when working on the machine. This includes the following items:-
Safety gloves, including where necessary cut resistant knitted Kevlar. Earplugs or ear defenders as appropriate.
Safety boots or shoes with protective soles and toecaps. Eye/face protection, if necessary full face mask with under chin lip.
Respiratory masks. High visibility jackets or waistcoats.

Operating Advice
Please remember, the information provided in this manual is designed to ensure that the Scarab sweeper operates both safely and efficiently.
The design of the machine is for the removal of spoil on traffic or pedestrian areas also litter collection using the wander hose if fitted.
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 a more efficient collection of material. This is because wet material is heavier and will drop more readily from the air stream in the hopper.
If swept dry, material will pass through the screen wearing out the suction fan blades on its way back out to the environment behind you.
Operators should be trained in the following elements:-
• Health and Safety observations/notices.
• Driving to and from place to be swept (transit driving).
• In cab and external controls.
• Safety prop use, cab, rear door and hopper.
• Brush setting.
• Nozzle flap adjustment.
• Correct sweeping operations.
• Low and high pressure water systems.
• Load discharge (tipping).
• Daily, weekly maintenance schedules.
• End of day cleaning, i.e. suction fan, fan screen and machine body.
Operator training can be provided by Scarab Sweepers upon request.
The USB connection in the LCD monitor is for uploading/downloading machine related information and must not be used for anything else.
It is the responsibility of employers to carry out their own risk assessment of the machine, operators or other persons 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 systems.
For information regarding vehicle/chassis operation and maintenance, please refer to chassis manufactures’ handbook.

Operating In Sweep Mode
Refer to Health and Safety Advice on page 10.
Reducing Noise Levels and 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 areas
which are 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 benefits from reduced noise levels in 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 CAN Bus system checks that all control nodes are present and functioning correctly.
• The LCD Monitor turns on and for a few seconds displays a Scarab logo (splash) screen.
• The LCD Monitor then displays a simplified graphic of the truck, the time and auxiliary engine speed.
If an error is detected at this stage the ‘Fault Active’ symbol will be displayed on the LCD monitor.
To identify the error, refer to the Options Screen menus ‘Driver’s Fault Codes’ on page 44.
To start the auxiliary engine:
1. Press and hold down the ‘System Start/Stop Sweep Mode’ button until the auxiliary engine starts. When the auxiliary engine starts its default idle
speed of 950 rpm will display in the top right of the LCD monitor.
With the auxiliary engine running, the system is now effectively in Sweep Mode and a number of symbols representing the installed sweeping equipment
will appear superimposed over the truck graphic on the LCD monitor.
2. On the control panels, select the desired sweeping equipment. Refer to pages 14, 15 and 16 for more information.
The auxiliary engine speed will increase if the following functions are selected:-
Suction Fan and/or High Pressure Water Pump*, auxiliary engine speed rises to 1200 rpm.
Suction Fan Boost, auxiliary engine speed rises to 1700 rpm.
