Chapter 1 General description
1.1 Contents and purposes
Potential risks concerning the use of the machine are listed in the following
sections. Since most accidents take place when safety rules are ignored, it is
necessary that you read them carefully and take precautions before getting
started. The best guarantee against any accident is a careful and cautious user,
which might be better than other precautions available. When using the
machine, pay special attention to the people in the working area, especially
children.
1.2 General instructions
Before any maintenance and repair, turn off the power and remove the key
from the general switch.
The machine can only be operated by qualified personnel. Children and
disabled people are strictly forbidden to use it.
Keep the battery away from sparks, flames and smoke.
Do NOT use the machine in places with dangerous, flammable or explosive
gases, liquids or water vapor.
The machine can be used to clean regular garbage. It must NOT be used to
clean silk ropes, belts, high-temperature sundries, accumulated water, or
flammable, toxic and harmful materials, so as to avoid entanglement and
burning of the brushes.
Keep loose clothing, hair, fingers and other parts of your body away from the
air vent and any moving part of the machine.
Turn off the power if you do not use the machine.
Do NOT use the machine in slopes with an inclination larger than the fixedvalue.

If some spare parts need to be replaced, you can purchase them from the
original manufacturer or an authorized distributor.
To make sure that the machine is in the proper operating and safety condition, the
user or service center must abide by what is stated in Chapter III and Chapter V.
Attention must be paid even when the machine is about to be dismantled and
scrapped. Since some harmful substances (such as batteries, waste oil, etc.) have met
the required standards, they should be sent to a specific center for treatment.
1.3 Safety requirements for batteries
The battery must NOT be in a low voltage state; charge the battery as soon as
possible when the voltage is below 42 V;
To avoid electric leakage, keep the battery dry and clean;
Do NOT put metallic objects (such as tools) on the battery to prevent it from
being short-circuited and burned;
The charging room should be well ventilated;
When the key switch is in the position “ON”, do NOT install or remove the
battery;
Before installing or removing the battery, disconnect first the negative wire (-)
and then the positive wire (+). When rewiring, pay special attention to the
polarity of the battery, as wrong connection would probably damage electrical
components;
Avoid direct contact between the positive and the negative electrodes, because
it would cause a large current short circuit, high heat or even a fire.
1.4 General safety requirements
In addition to what is mentioned in this manual, the general safety
requirements must also be observed. Even if you have used a similar product
before, we recommend that you read this manual carefully so that you can
save much time as well as take precautions to protect the machine and
yourself. It is vital that you become familiar with all the accessories and
components before turning on the machine. Read our instructions carefully so
that you will not be confused when you get started.

should be vibrated regularly: stop the machine, press the dust-vibrator button
to start the dust-vibrator motor and keep it operating for one minute.
During the work, the filter screen should be vibrated every 30 minute on
average (depending on the working area)
The machine cannot collect garbage when the filter screen is blocked or the
garbage can is filled. Do NOT use the machine on the damp ground to prevent
the filter screen from being damaged.
The garbage can must be discharged every time when the work is finished.
2.3.2 Discharging the garbage can
Release the pedal to stop the machine.
Open the buckle of the garbage can.
Pull the garbage can downward, drag it out and take out the garbage.
Put the garbage can back in the machine and fasten the buckle.
2.3.3 Push/drag of the machine

rotation.
Any adjustment must be realized on
the flat ground.
Make sure that the main brush is
stopped and the machine is
powered-off.
Check the width of the contact
surface with the ground. The
appropriate width range is 2-4 cm.
If the width of the contact surface is
not within this range, adjust the
position of the main brush.

3.3 Replacement of the main groom
Before replacing the main brush, place the machine on the flat ground and
make sure that it is powered-off.
Open the right board of the machine, use an open-end wrench to remove the
rocker arm of the main brush, the sealing plate and the fixing nuts of the baffle
bracket.
Take out the old brush and replace it with a new one (first install the sealing
plate nuts, then the baffle bracket nuts and finally the rocker arm nuts).
Turn on the sweeping button and check whether the main brush works
normally; if not, use the rocker arm to adjust it.
3.4 Adjustment and replacement of the side grooms
The side brushes can sweep out garbage in dead corners so that the cleaning
efficiency of the machine can be boosted.
3.4.1 Adjustment of the side brushes
Use the adjusting nuts on both sides to adjust the position of the side brushes.

8
3.4.2 Replacement of the side brushes
Step 1: loosen the Allen screws of the side brushes;
Step 2: remove the screws shown in the picture and take out the old brush(es);
Install the new brush(es) in the reverse direction.
Note: use gloves to protect your hands from being hurt.
3.5 Replacement of the filter element
The filter is used to remove dust and small particles. When dust and high-density
garbage such as leaves cannot be cleaned, the filter element needs to be replaced.
Remove the nuts on the panel of the dust-vibrator motor and pull out the
filter element.
Remove the screws inside the filter element and replace the filter element.
Apply lubricating oil to the seal of the new filter element.
Install the filter element in the reverse order.
3.6 Adjustment of the height of the baffles
The main function of the baffles is to concentrate the suction force of the sweeper.
If the side and the rear baffles are off the ground, garbage may be missed during
the cleaning.
Take out the garbage can.
Check if the baffles are complete. When the gap is larger than 20mm or the
crack is larger than 10 mm, replace the corresponding baffle.
Check whether the height of the baffles are between 0~3 mm. If it is not within
this range, adjust the height of the corresponding baffle.

9
3.7 Replacement of the fuses
When an electrical unit is overloaded or the current is too large, the
