Push the coiled end of the squeegee hose fully home onto the tubular spigot in the centre of the squeegee. Push the straight end of the squeegee hose onto the tank inlet pipe which protrudes through a slot in the lower rear panel. Keyswitch/accelerator sequence: This safety feature prevents the machine from moving if the machine is accidentally switched on with either forward or reverse function engaged (due to machine fault or an operator error). When this happens the leds on display panel begin flashing. Mosfet short circuit: This safety feature prevents the machine from moving if the machine is switched on with the the part of the electronic print card controlling drive power is in short circuit (in this case the machine would move immediately at full speed). This condition is signalled by the 3 voltmeter leds which start flashing. Overheating of the electronic print card cooling vents: This protection device of the electronic print card prevents damage to the card itself during prolonged use of the machine when one of its functions is overloaded. In this condition the machine automatically cuts off all its functions which are then only restored when temperature returns to normal value. This condition is signalled by the lighting up in sequence of the 3 voltmeter leds. Micro switch: Micro switch to shut off all the functions when the tank is in the upright position. (SEMKO APPROVAL) PREPARATION FOR USE 6 MAINTENANCE 19 For models working with batteries follow instructions below, whereas in the case of mains operated models the transformer 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 before they can be used. Take special care when handling the acid as it is corrosive, If it should come into contact with skin or eyes, wash abundantly with water and consult a doctor. The W345B & W355B machines use two 12 volt batteries, the W365B & W375B machines use four 6 volt batteries. Study the illustrations then fit the batteries and connect the links supplied as indicated. Plug the battery socket into the machine as shown. Fold over the flaps to cover the battery tops, then lower the tank unit to safely cover exposed working parts. The three solenoid valve bodies may be removed by turning them through 45 degrees and lifting them away to reveal the plunger and seating of each valve. These should be cleaned of scale and of any other foreign matter. Regularly inspect the squeegee for damage or wear to the lips. The lips may be easily replaced by unscrewing the retaining strips, remove the lips, replace with new, then screw the cover strips back again to retain them. Important:periodically clean the suction filters; this is very important not to reduce the suction capability of the squeegee. - + + - - + - + - + + - MAINTENANCE 18 PREPARATION FOR USE 7 The machine may now be run for trial purposes but before putting it into service the batteries should be charged to bring them up to their maximum capacity. New batteries will gradually “run in” and increase in capacity to a maximum in about the first 10 charge/discharge cycles. If necessary the batteries should be charged using an appropriate battery charger. Remove the battery caps during the charging operation. Check that the Hertz and Voltage readings of the mains supply correspond to those of the battery charger. BEFORE ANY MAINTENANCE IS CARRIED OUT THE BATTERY MUST BE UNPLUGGED OR THE MAINS LEAD UNPLUGGED. Periodically unscrew the filter inside the scrubbing detergent tank, scrub whit a stiff brush under running water to remove any accumulated foreign matter. Note: for the models 345-355 it is enough to pull the filter to remove it. Press the filter to mount it. For the battery operated models, the level of the liquid inside batteries must be checked periodically, and topped up with distilled water if necessary. Raise the bonnet, uncover the battery compartment, remove caps and check level. Special care should be taken when handling battery liquid as it is corrosive. If it should come into contact with skin or eyes, wash abundantly with water and consult a doctor. Recharge batteries when necessary with an appropriate battery charger. 345-355 365-375 PREPARATION FOR USE 8 CHANGING BRUSHES 17 Drop the brushes (one or two depending on the model) roughly side by side in front of the machine, the actual position does not matter. Switch the machine on by turning the key in the key-switch a quarter turn clockwise. Wait momentarily until the battery condition indicator above the switch lights. Note : The mains machine will have to be plugged in, the indicator then only shows that power is available. Drive the machine forward by holding the handgrips, then rolling the thumb wheels forward until the machine moves completely over the brushes. To stop release the thumb wheels and they will return to a neutral position. This will ensure the brushe...
