4.5 Charging the batteries
Note: the machine is powered by two 12 V maintenance-free lead-acid batteries and the total system voltage is 24 V.
 The total voltage of the batteries will gradually decrease during the work. When the last bar of the voltmeter is flashing, the
machine is running out of power and charge the batteries immediately.
 When maintaining the batteries, please wear gloves to avoid contact with acid substances.

Check whether the battery cords are worn and the connecting parts are loose, and replace them when necessary.

Keep the batteries dry and clean and make sure that there are no dust on them, since it is extremely harmful to the batteries
and may even cause them to burn in severe cases. Do NOT put any object (especially metallic object) on the batteries either.

In order to extend the service life of the batteries, charge them immediately when the cleaning work is finished. Deep
discharging is strictly forbidden for it will reduce their capacity and service life.
 The correct steps of charging the batteries: first install the batteries, then connect them to the mains.
 If the machine is not about to be used within a long period of time, please fully charge the batteries and disconnect the battery
cords.
Chapter 5 Cleaning and maintenance of the machine
Regular maintenance can extend the service life of your machine.
5.1 Cleaning of the machine
 Check the wheels regularly and remove entanglements.
 Clean the sewage tank and the sewage discharging pipe with clean water regularly.
 Clean the filter of the water valve. If there are impurities in its transparent cover, unscrew the filter and wash the cover
and the filter screen repeatedly.
Alert: do NOT wash the machine body with water directly, since it is NOT strictly water-proof and may be short-circuited or
burnt in this case.
5.2 Maintenance of the machine
5.2.1 Replacement of the brush plate
