Fault Handling
25. Machine that Cannot be Started
1. Check whether the batteries are fully charged.
2. Confirm whether the power system connector is connected to the batteries.
3. Check whether the main switch is turned ON (in the ON position).
26. Brush with Insufficient Water Supply (Fig. 25)
1. It is necessary to check whether there is
water in the clean water tank, and visually
check the water level of the water level pipe of
the clean water tank.
2. It is necessary to check whether the valves
(D) of the water pipes on both sides under the
clean water tank are closed, and if they are
closed, they need to be unscrewed.
3. If the above two items do not solve the water
supply shortage, it is necessary to check
whether the filter screen of the filter (E) of the
water pipes on both sides under the clean water
tank is blocked, and if it is blocked, it needs to
be cleaned up.
4. If the shortage of water supply is not solved
in the above three items, it is necessary to
check whether the electromagnetic control
valve and pipeline connectors of the water
pipes on both sides under the clean water tank
are blocked by scale, and if so, please replace
relevant parts.
27. Suction Scraper that Cannot be Completely Sucked Dry
1. Please check whether the suction scraper is clean.
2. The setting of the suction scraper must be checked (see "Preparation for Machine Use" for
details).
3. The whole sewage tank must be cleaned (see "Weekly Maintenance" for details).
4. If the rubber scraper is worn, please replace it (see "Special Maintenance" for details).
28. Machine that Cannot be Cleaned
1. Please check the wear condition of the brush tray and replace it if necessary. If the bristles are
shorter than 15mm, they need to be replaced. For replacing the brush, please refer to the chapter
"Disassembly and Installation of Brush Tray". If the brush is excessively worn, it may cause
damage to the floor.
2. It is necessary to use different kinds of brushes as standard equipment. If it is particularly
difficult to clean the dirt on the floor, we suggest that you use a special brush according to your
needs and our requirements. (See "Selection and Use of Brush" for details).
