pad (D) and align them with the mounting
holes of the two mounting seats, then align
them with the two threaded holes of the suction
scraper, and finally tighten the star handles.
5. Insert the sewage suction pipe (F) into the
connector in the middle of the suction scraper.
12. Angle Adjustment of Suction Scraper (Fig. 11)
In the process of operation, the rubber scraper behind the suction scraper must be slightly tilted
backwards (about 5mm) to ensure the overall length to be uniform. If it is necessary to bend the
middle rubber scraper, the suction scraper must be tilted as follows:
1. Turn a star handle (A) clockwise to make the rubber scraper of the suction scraper in the
middle part bend continuously, and adjust it until the rubber scraper leans back slightly (about
5mm).
13. Height Adjustment of Suction Scraper (Fig. 11)
The height of the scraper must be adjusted according to the wear state of rubber, which mainly
includes the following steps:
1. Rotate two star handles (B) clockwise or counterclockwise to adjust the height of the rubber
scraper of the water suction scraper. When rotating clockwise, the rubber scraper will rise, and
when rotating counterclockwise, the rubber scraper will fall. If the rubber scraper is worn, rotate
counterclockwise to adjust the two star handles (B).
Note: It is necessary to use protective gloves for these operations to avoid touching sharp
edges or tips of metal objects.

unloading button (8) on the control panel (the green light is on), and the brush tray will be
automatically removed without manual disassembly.
4. If you want to install or replace the brush tray, firstly, the brush tray cover (A) is in a raised
state, then manually place the two brush trays (B) in the center position corresponding to the
rotating shaft of the brush tray cover (approximately in the center position, but not too far away
from the center position of the rotating shaft), and then press the brush button (12) on the control
panel (the green light is on), so that the brush tray cover (A) will brush. Then please visually
check whether the brush tray is completely covered in the brush tray cover (A). If the brush tray
is not covered in the brush tray cover (A), you can use auxiliary tools to move the brush tray to be
completely covered by the brush tray cover (A). If the brush tray cannot be adjusted, you can
press the brush button (12) again until the brush tray cover (A) will automatically rise after the
brush installation program is automatically executed. After the brush tray is successfully installed,
the brush tray will be automatically installed and raised without manual installation and lifting.
Warning: Do not let people or things near the brush during operation.
Note: Please pay attention to whether the brush is inserted normally. Otherwise, the machine will
suddenly move irregularly during operation.
Caution: Protective gloves must be used for these operations to avoid contact with sharp edges or
