Setting the operator pre-set buttons Machine Operation Settings can be stored using one of the three pre-set store buttons (S1/S2/S3). Once settings are entered (chemical dose, brush speed and water-flow), press and hold one of the three pre-set store buttons, a light will flash then remain constant; your settings are now saved. This facility can be re-set as often as you wish by simply following the steps above. S1 S2 S3 Cleaning Speed setting (CS). When this button is activated the speed is restricted to 3.5km/hr maximum even with the accelerator pedal fully depressed. This is ideal for long cleaning periods. Once this pre-set button is switched-off, the machine will operate at up to a maximum speed of 7.0km/hr. CS Waste-water tank fill level warning light When the waste water-tank becomes full, a red warning light will illuminate on the operator control panel (as illustrated) and the vacuum motor will stop automatically after 5 seconds. The waste-water tank requires emptying (see page 17). Brush pressure / Load adjustment The machine is equipped with a brush-pressure load-warning system. If the brush load increases due to changing floor types, the pressure can be adjusted manually by the operator using the adjuster knob found on the left hand side of the control column. Turn it anti-clockwise to decrease load on the brushes and clockwise to increase load/pressure on the brushes (see Fig.25). NOTE: The run-time of the machine may decrease if the load on the brushes is increased. 14 Fig.25
