Sweeping
If considered appropriate reduce engine speed to suit the prevailing sweeping conditions, by means of the engine speed controls on the main panel. Auxiliary 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.
1. Switch on the hazard warning beacons.
2. Switch on suction fan (approx. 2000 rpm) or Boost (approx. 2200 rpm) as required.
The suction fan symbol on the LCD Monitor will change from GREY to GREEN .
Fan speed can be confirmed by referring to the LCD screen.
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).
6. Select on the vehicle the forward ratio best suited to the prevailing sweeping conditions and commence sweeping.
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.
