The machine is now ready for use again. CHANGING BRUSHES 16 PREPARATION FOR USE 9 Lower the brush unit by pushing the pedal to the right to unlatch it. Then allow it to rise as far as it will go. Push the machine forward then back about 50mm (2”) to ensure the drive has located in the brushes. Press the brush “on/off” push button: the indicator will light and the brush motors will engage the brushes. Once the brushes have locked on, raise the brush unit by pushing the pedal down and latching it at its lower position. Press the brush “on/off” push button again (see previous picture); the green indicator will wait for the motors to spin down to stop before going out. Note : The motors do not stop immediately. The brushes are now loaded onto the machine. To replace brushes carry out the following sequence of operations: The machine should be switched on but all functions switched off. Raise the brush unit by pressing down the brush lift/lower pedal and latching in its lowest position. Press the brush release push button momentarily and the brushes at present fitted will be unloaded from the machine. Move the machine backward by rolling the traction control rearward until the brushes are visible in front of the machine. SCRUBBING YING OPERA TION SCRUBBING YING OPERA TION SCRUBBING OPERATION SCRUBBING OPERATION Open the tank lid. Fill the left tank with water to within about 75mm (3”) from the top edge then add the scrubbing detergent in a quantity to make a dilution according to its instruction. Too strong a mix wastes detergent, too weak a mix will not work efficiently. The machine is now ready for use so move off to the site to be cleaned. Switch the machine on by turning the key in the key-switch a quarter turn clockwise. Unclip the recovery tank emptying remove the drain plug its highest extent, then gully or drain. Note: It is against Water Regulations to discharge detergents into a surface drain, only use a foul gully or drain. At the same time as emptying the recovery tank check if the clean tank requires refilling. If the clean liquid runs out then it is recommended that to save time the recovery tank be emptied at the same time as the clean tank is refilled. A switch is fitted on the rear panel to the right of the control handle which controls the drive motor power. With the switch lever in the up position the traction motor is disconnected and the machine may be pushed easily from site to site when the mains lead is unplugged or when the batteries are not available. OFF ON SCRUBBING AND DRYING OPERATION 14 SCRUBBING AND DRYING OPERATION 11 Press the brush “on/off” push button: the indicator will light and the brush motors will start. Lower the brush unit by pushing the pedal to the right to unlatch it. Drive the machine forward by holding the handgrips. And turning the thumb wheels. Push the machine slowly forward, and adjust the squeegee pressure control until the lips bend over evenly as illustrated below. Then re-adjust the rake control to make the radius of the squeegee sit parallel to the floor and the lips bend evenly. The lips must be replaced when they become feather edged or torn. Fully lift the squeegee control lever (just below and to the right of the machine handle) to lower the squeegee to a flat floor surface. If the recovery tank full indicator lights continuosly for a period of 6 seconds the suction motor will switch off and the tank will have to be emptied before continuing the operation. Note: Lift the brushes whilst still moving forward then stop traction, in that order, to avoid “polo rings”. Lift the squeegee and stop the suction motor. Drive the machine to an emptying point or use a transfer trolly to empty the recovery tank. TRAVEL DIRECTION FLOOR LEVEL SCRUBBING AND DRYING OPERATION 12 SCRUBBING AND DRYING OPERATION 13 When the machine is ready for scrubbing select the estimated amount of clean liquid required by pressing the detergent flow control on/off push button; an indicator will light which can be increased in three steps for varying the quantity of liquid delivered to the brushes. If more liquid is required press the boost pump on/off push button which will double the amount of flow; this will be shown by the indicator. Lower the squeegee to the floor. Press the suction on/off push button. Start the brushes rotating, move the machine slowly forward, then immediately lower the brushes to the floor by lifting the foot pedal. (If the brushes are allowed to rotate in contact with the floor without the machine moving then it is likely to cause “polo rings” on the floor). Whilst moving forward observe the cleaning effect on the floor and adjust the detergent flow to the minimum required whilst being liquid enough to be picked up by the squeegee. This allows the liquid to last longer before having to refill the tank. If too little liquid is used the floor will dry with a “sludgy” grey look to it. The height of the drive handle can be adjusted by turning the knob A. The speed r...
