MAINTENANCE Periodically remove the filter inside the dirty water tank, scrub it with a stiff brush under running water to remove any accumulated foreign matter. TECHNICAL SPECIFICATION MODELS Voltage Drive motor Vacuum motor rating Vacuum depression (mm H2O) Note: This operation is very important to prevent the reduction of the suction (drying) capability of the squeegee.
MACHINE CONTROLS AND MONITORS 4 56 MAINTENANCE BEFORE ANY MAINTENANCE IS CARRIED OUT THE BATTERY MUST BE UNPLUGGED, OR THE MAINS LEAD UNPLUGGED.
CLEANING OR REPLACING THE BRUSHES PREPARATION FOR USE To replace the brushes (or to clean them) carry out the following sequence of operations: Partially unscrew the two middle levers on the squeegee. Push the squeegee into the locating lugs as illustrated and fully tighten the hand-levers. (Pull the lever up to disingage it and make its rotation free). The machine must be switched on but all functions switched off; it means that the squeegee must be lifted.
PREPARATION FOR USE SCRUBBING AND DRYING OPERATION For models working with batteries follow the instructions below, whereas in the case of mains operated models the transformer (or mains unit) has already been placed inside the machine and needs no further installation. The batteries are supplied without liquid, therefore they must be filled up with the appropriate acid solution (concentration greater than 30%) before they can be used. Take special care when handling the acid solution as it is corrosive.
SCRUBBING AND DRYING OPERATION PREPARATION FOR USE After filling the batteries must stand for at least 1 hour and then they must be filled up if necessary. After one further hour the batteries must be recharged: remove the battery caps during the recharge operation. The new batteries will gradually “run in “ and will increase their capacity. The maximum capacity will be achieved in about 10 charge/discharge cycles.
PREPARATION FOR USE SCRUBBING AND DRYING OPERATION Drive the machine forward by holding the handgrips, then rolling the thumb wheels forward until the machine moves. In the event of a temporary stop (releasing thumb wheels) the automatic switch-off of the all functions will occur (AUTOPOWER-OFF). B A For models equipped with parking brake: press pedal A to engage the brake. Press pedal B to disingage it.
SCRUBBING AND DRYING OPERATION PREPARATION FOR USE C In order to achieve a further reduction of the water flow the water pump can also be switched off by means of push button C. The same button allows to re-switch on the water pump. ON OFF NOTE: on all versions of model AW445 (without traction) the push button C is not available. Drive the machine forward by holding the handgrips, then rolling the thumb wheels forward until the machine moves completely over the brushes.
SCRUBBING AND DRYING OPERATION Once the brushes have been locked on, raise the brush unit by pushing the pedal down and latching it at its lower position. Now the machine is ready for use. SCRUBBING AND DRYING OPERATION A The height of the handle can be adjusted using the dedicate knob A. B The speed range can be selected by means of switch B. Switch the machine “on” by turning the key in the master key-switch a quarter turn clockwise. Open the tank lid.
