Operating In Sweep Mode; Sweeping - Scarab MERLIN Operating And Basic Maintenance Instructions

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.

Sweeping

Engine ON. Neutral gear selected. Parking brake ON.
1. Switch on the hazard warning beacons.
2. Press the Sweep Mode switch.
equipment will appear superimposed on the truck graphic, displayed on the LCD monitor.
3. Switch on suction fan
that increased engine speed might be necessary. Fan speed can be confirmed by referring to the LCD screen.
4. Select the desired configuration of sweeping equipment and water sprays if required, either manually or by pressing the Favourite Settings
switch to recall your preferred arrangement. Switch on work-lights if required.
If considered appropriate reduce/increase engine speed to suit the prevailing sweeping conditions, by means of the engine speed controls
on the main panel. Engine speed can only be adjusted between its minimum effective speed for the situation and the active preset default speed.
Be aware that too much reduction of engine speed can adversely affect suction performance.
5. Move the Multi-Function Lever (located on the auxiliary control panel) to the ON position to start and deploy the pre-selected
sweeping equipment.
To stop and stow the sweep gear, return the lever 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).
