To ensure the proper operation and safety conditions of the machine,
professionals or service centers must follow the maintenance section of this
manual work.
Even if the machine is to be disassembled and scrapped, people should pay
attention to it as some harmful substances (such as batteries, waste oil, etc.)
shall be sent to a specific Center for treatment.
Machines equipped with lead (wet) batteries shall not be tilted more than 30 °
above the horizontal ground, so that the battery is highly corrosive acid will
leak. The machine must be tilted during maintenance. Please remove the
battery.
SAFETY REQUIREMENTS FOR BATTERIES
It is necessary to avoid the battery in low voltage state and charge it as soon
as possible.
The battery is 12V lead-acid maintenance-free battery.
To avoid leakage, keep the battery dry and clean, especially remove
pollutants such as metal dust.
It is forbidden to place metal parts (such as tools) on batteries in order to
prevent short circuit burnout of batteries.
When reclaiming batteries, please comply with local regulations.
It is forbidden to use open fire when handling and handling batteries.

6
The charging room should be well ventilated.
When the key switch is in the ON position, it is forbidden to connect or
disassemble batteries.
Before disassembling and assembling batteries, first disconnect the negative
(-) battery wire, and then disconnect the positive (+) battery wire. When re-
wiring, we must pay attention to the polarity of batteries, wrong wiring will
damage electrical components;
Avoid direct contact between positive and negative electrodes, because it will
cause high current short circuit, high heat and even the possibility of fire.
When the battery is charged, it generates explosive hydrogen, charges the
battery in a ventilated place, and keeps the lid open and away from the open
fire.

MACHINE OPERATION PRECAUTIONS
NOTE!
In the process of work, determine whether to start the vibration device
temporarily according to the amount of garbage on the cleaned ground.
When the filter is blocked or the bin is full, the machine cant collect
the garbage. After each work, the dustbin must be emptied. (if the
dustbin is full in the work, please empty it immediately.) if the
temperature is lower than 0 ℃, please pay attention to drain the water
in the dustbin to prevent freezing!
WARNING!
Avoid stopping the machine at the same place for a long time and
rolling the brush; this will leave traces on the ground
When collecting large garbage, please remember to lift the front wheel
slightly and move forward. Note that it is only lifted for a short time.
In order to make the machine have a good cleaning, be sure to clean
the filter. Step the vibration on the side of the bin for about ten times
to shake off the dust on the filter.
CAREFUL!
Decide whether to clean the filter according to the dirt of the cleaned
area.
The dustbin must be emptied every time after working. When the main
brush and the side brush are worn, the screw at the rear of the
machine can be adjusted to lower the main brush and the side brush,
and the adjustment cannot be too low. Clean them to avoid burning
the fuse. (during the first cleaning, there is no need to adjust, and the
companys staff has adjusted it)

MACHINE PRESERVATION AND MAINTENANCE
If the machine will not be used within 30 days, follow the procedure below:
Store the machine in a clean and dry place.
Disconnect the battery connector.
First use
After the first use (the first 8 hours), it is necessary to check the following
operations:
Check the connection and fastening parts for looseness.
Check whether the visible parts are intact.
Check the main side brush for excessive wear.
WARNING!
To perform maintenance operations, the battery must be removed
when the machine is stopped (the start switch key is removed) and if
necessary. Therefore, please read the safety section of the manual
carefully.
MAIN BRUSH HEIGHT INSPECTION AND ADJUSTMENT
The height of main brush has been adjusted before leaving the factory. After
using for some time, the main brush will be worn and it is necessary to adjust
the brush. Turn the rotary handle at right hand anticlockwise to lower about
2mm, so that the main brush is 3-5mm in contact with the ground. (Figure 4)

1
Figure 3 figure 4
When the main brush is seriously worn and the rotating handle has turned to
the last stage, please open the front cover and adjust it as follows:
Adjust the right rotating handle to the initial position (Figure 3) turn the nut 1
clockwise (Figure 4) to make the main brush brush hair touch the ground for 3-
5mm
Cover the front cover properly
Repeat the last process (main brush height inspection and adjustment ).
MAIN BRUSH REPLACEMENT
1. Remove the cover screws (Figure 5)
2. Loosen the left and right rocker arms of the main brush (Figure 6)
3. Disassemble the rocker arm.
4. Lift up the machine and take out the main brush (Figure 7)
5. Take out the left and right heads of the main brush.
6. Install the left and right head on the main brush, and pay attention to the
installation direction.
7. Install the main brush on the sweeper and tighten the bolts (Figure 8)
8. Adjust the adjusting screw of the main brush to the position where it is used
for the first time, so that the main brush hairs touch the ground for 3-5mm
9. Install the cover.
Figure 5 Figure 6

Figure 7 Figure 8
CAREFUL!
The hard brush or soft brush can be selected according to the ground
conditions; when replacing the main brush, it is better to wear gloves,
because it may be cut by the brush; the operation direction of the main
brush is shown in Figure 5, and the main brush shall be installed
correctly as shown in the figure, and the pressure between the main
brush and the ground shall be checked as described in the relevant
chapters.
SIDE BRUSH HEIGHT ADJUSTMENT
When the sweeper leaves the factory, the height of the edge brush has been
adjusted to be qualified. When it is used for a period of time, the side brush
cannot clean effectively, and it is necessary to adjust the side brush. Turn the
left rotary handle clockwise for 1 stage (Fig. 9), and clean it.
Figure 9 Figure 10
SIDE BRUSH REPLACEMENT
The main function of the side brush is to collect the garbage on both sides into
the middle by using its own rotation, and then the main brush will collect it into
the garbage bin. The advantage of the side brush is that it can sweep out the
garbage at the corners and dead corners and increase the cleaning area.
Use the machine on the level ground, turn the starting key of the machine to
"off" position.
Lift up the machine and loosen the four bolts at the bottom of the brush disc
(Figure 11)

1
Replace with a new side brush.
Adjust the height of the side brush according to the instruction.
VIBRATION
After continuous operation of the sweeper for a period of time, the capillary
hole of the filter is might be blocked. Please use the dust vibrating function
regularly:
Turn off the machine power supply.
Step the dust vibrating pedal for ten times to shake off the dust on the
filter(Figure 11).
Figure 11 Figure 12
FILTER CLEANING AND INSPECTION
Use the machine on flat ground, turn the machine start key to "off" position
and remove the dustbin. Lightly scrape the bottom of the filter with a burr free
bar.
Please note the following: do not use water or detergent to clean it, the filter
will be damaged. Replace the filter when there is crack on it.

BATTERY CHARGING
After each use, when the warning light is on, charging the battery will prolong
the battery life.
If you want to stop charging, disconnect the AC socket switch before
disconnecting the DC socket, and then take the DC plug after the charger is
disconnected(Figure 12).

out the dustbin (Figure 13).After cleaning the garbage, put the dustbin inside
and then lock the buckle.
Figure 13 Figure 14
NOTE!
When the machine stops working, the brush must be lifted to prevent
deformation of the brush.

WATER INJECTION
Turn the water filling cover anticlockwise to add water(figure 14).
NOTE!
When the temperature is lower than zero, please empty the water
tank!
SQUEEGEE INSPECTION AND ADJUSTMENT
1. Place the machine on a flat ground suitable for checking the height of the
squeegee.
2. Turn the starting key of the door to the "off" position.
3. Check the integrity of the side squeegee.
4. Check whether the height between the squeegee and the ground is within 0-
3mm.
5. Raise the front wheels of the sweeper
6. Check the integrity of the front and rear squeegee
7. The front squeegee slightly touches the ground but not separated from the
ground
8. The height between the back squeegee and ground is within 0-3mm
