Operating Instructions Scarab M6
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.
