affect the cleaning effect. * Do not use single rolling brush cleaning
mode to avoid falling risks.
* If the bristles are deformed under
pressure for a long time, it will cause the
bristles to become irreversibly deformed.
* When moving the roller brush, special
handle should be raised. It is strictly
forbidden to pull the roller brush shaft to
prevent deformation and damage of the
roller brush shaft.

4.5.3 Start the Kwun
1. Corner placement
Select the starting point with the least number of turns for
horizonal autonomous operation.
Kwun is placed on the bottom corner of the left and right
sides of the photovoltaic array that meets the requirements.
3. Position calibration
Adjust the horizontal central axis of the device to the spacing line of the
cells in row 1 and row 2 in the lower corner, and the horizontal central
axis to the spacing line of the cells in row 1 and row 2 in the lower corner.
2. Turn on the power
Press the power button to start the device. When the first red
light is off, the device is normal and enters the initialization
state.
4. Start the job
When the green light is steady on and the red light is off (the buzzer
beeps once), and the initialization is successful (about 22s), press the
start/standby button to start the device.
The interval between components is less than 4cm
The height difference is less than 1cm
The identification area at the bottom of the PV array edge
is 5*8cm(width * depth) barrier-free.
Dry brush tilt less than 10°, wash tilt less than 5°
* Holes on the support plate of the synchronous wheel indicate the central position of Kwun,
which can assist in position calibration.
* The main grid line 0BB PV module needs to be closer to the interior due to size problem,
and should be placed according to the number of rows and columns +1 indicated above.

4.6 Function application
4.6.1 Unmanned cleaning / 4.6.1.1 Array
After the start and identification is completed, the Kwun climbs up to the top of the photovoltaic array and tries the direction. After
the direction is determined, the operation begins. The Kwun turns around to span until the array is covered, and chooses the
termination according to the berthing mode.
