Working principle of machine
Sweeping method
First, collect garbage on both sides of driving route to the bottom through side brush, and the garbage
will enter into rolling brush box when the machine move forward. Second, the garbage will be swept
to garbage can at the back of machine by rotating rolling brush, then dust in garbage can will be
absorbed into filter by the vane wheel on rolling brush motor. When the sweeping is end, the dust
collected by filter screen will be dropped into garbage can after pressing vibration button. Finally, take
the garbage can out and empty the garbage at designated place.
Sweep parts: a garbage can, a rolling brush
and two side brushes.
The button on control panel is able to
control the sweeping and brushing of
machine. Open the switch of side brush
and rolling brush, and put down the handle
of side brush at first,, then move the
forward and backward switch on the
position of “Forward”, adjust the speed
switch (adjust proper height according to
different ground.) and finally step on the
pedal to start cleaning.
There are two available side brushes and
one rolling brush, the diameter of side
brush is 380 mm and the length of rolling
brush is 600 mm.

such as, metal wire, coil , string and so on.
Cleaning method shall be made in advance, please try to make a long term arrangement and minimize
the times of stopping and starting machine. Do not clean the whole floor or area one-time.
Gravity sensor of sweeper seat:
If the seat is idle without supporting any weight after starting the sweeper, the machine can not move
forward even you step on the pedal, and it can work normally as long as the operator sit on the seat or
add pressure on it, which have a function of safety protection to avoid the occurrence of accident
(Figure 8).

1) When the machine is placed or parked in a fixed place in the transportation, the electromagnetic
switch shall be started to avoid unexpected sliding, which is located in front wheel. The steering wheel
is required to be rotate to the right side completely after parking the machine stably, or it is feasible to
adjust the front wheel by manual. ( As shown in Figure 9).
2) Electromagnetic brake status of sweeper: the fault indicator on control panel flash three times first,
and then flash twice; Pull the electromagnetic brake handle backward once, then the automatic brake
will be recovered, and the machine can work normally as well. (As shown in Figure 10).

Adjust the height of rolling brush
As shown in below figures, first, install two adjusting knobs on the baffle of each side of rolling brush,
unscrew the knob by taking the dot as central shaft of rolling brush, and then increase the height of
rolling brush in the counter clockwise direction or reduce the position of rolling brush in clockwise
direction, so that the worn rolling brush is able to work at proper height. Please observe the height of
rolling brush by referring the circular symbol on baffle.(Figure 12-13)

is very sensitive to the rotation of steering wheel, sharp turn must be avoided except the emergency
situation.
When arrives to the bottom of corridor, please sweep from the bottom toward opening of corridor.
Keep moving on to prevent damage to the ground.
If you find the sweeping efficiency is not good, please stop cleaning and read “Troubleshooting” of
machine carefully.
Sweeping method
Adjust the height of side brush and rolling brush to sweep floor according to the field situation.
Please pay attention to the indicator of battery level, in order to make sure there is enough power for
the operation of machine.
Before leaving the machine, please take the key out at first.
Daily maintenance shall be conducted after sweeping. (Please refer to “Machine maintenance”)
Drive slowly on slope: adjust the speed slower, and sweep the floor when the machine is uphill, not
downhill.
For the sake of safety: Drive the machine slowly on slope or smooth surface.
Do not operate machine under the area if the ambient temperature beyond 43℃(110℉).
Do not start sweeping under the area if the ambient temperature is lower than
0℃(32℉).
The maximum rated slope during the process of sweeping and transferring machine is 7% and 19.25%
respectively.
