machine.
Do NOT unload or unpack the machine violently.
2.2 Assembling the machine
2.2.1 Installing the squeegee
Use the squeegee lifting handle to put down the plastic squeegee holder.
Pass the squeegee fixing screws through the holes of the squeegee holder, and tighten them with plastic knobs:
2.2.2 Installing the sewage discharging pipe
Remove the cover of the sewage tank and insert the sewage suction pipe.
Insert the conical mouth of the suction pipe into the hole of the sewage tank, and the other end into the suction port of the
squeegee.

Chapter 3 Checks and adjustments before using the machine
3.1 Check items
3.1.1 Checking the water volume in the clean water tank
Make sure that there is sufficient water in the clean water tank before work. Do NOT do the cleaning without enough water, or
dust may be sucked into the suction motor leading to loud noise and low working efficiency.
3.1.2 Checking the water level in the sewage tank
Pay special attention to the water level in the sewage tank. When the floating balls are in the highest position, discharge the
sewage tank immediately or the suction motor will be burnt.
3.1.3 Checking the voltage of the batteries
When the general switch is turned on, the current voltage of the batteries will be displayed on the voltmeter. If the last bar of
the voltmeter is flashing, the power is insufficient and please charge the batteries immediately.
Note that deep discharging (e.g. frequently using the machine when the voltage is lower than 21 V) will reduce the service life
of the batteries.
6

3.1.4 Checking the degree of wear of the brush plate
Check whether the brush plate is worn. If so, adjust the height of the brush plate or
replace it.
3.1.5 Checking the degree of wear of the strip
The strip needs to be replaced if:
the strip cannot touch the ground when the squeegee is put down, or
the strip is cracked.
3.2 Adjustment of the squeegee
Use the nuts on the universal wheels to lift or lower the squeegee. Make sure that the squeegee touches the ground during
your work.

Chapter 4 Instructions on operating the machine
4.1 Walking of the machine
When the general switch is turned off, you can push the machine forward after the brush
plate and the squeegee are lifted.
When the general switch is turned on, you can push the machine forward when the brush
plate and the squeegee are lowered and started.
If you need to pull the machine backward, make sure that the squeegee is lifted or the strip
and the sheet metal will be deformed.
4.2 Scrubbing the floor
Put down the brush plate and the squeegee.
Turn on the switch button.
Turn on the drain switch, the electromagnetic valve will be started and the brush plate begins to work.
Turn on the brush plate button and the brush plate begins to rotate.
Turn on the suction motor button and the suction motor begins to work.
Push the machine forward with your hands to started the cleaning.
Note: when the brush plate motor is turned on, do NOT leave the machine in the same place for a long time, because this
would leave unnecessary marks on the ground.

4.3 Discharging sewage
Before discharging the sewage tank, stop the machine and turn off the general
switch.
Put down the sewage discharging pipe, open the cap and discharge the sewage.
Use clean water to wash the sewage tank.
9

4.4 Stopping the machine
When the work is finished, discharge the sewage tank.
Move the machine to an appropriate storage place.
Turn off all the buttons on the controlling panel.
Lift the brush plate and the squeegee.
Note: if the machine is not about to be used for a long time, please fully charge the batteries, disconnect the battery cords
to avoid power loss.
4.5 Charging the batteries
Note: the machine is powered by two 12 V maintenance-free lead-acid batteries and the total system voltage is 24 V.
The total voltage of the batteries will gradually decrease during the work. When the last bar of the voltmeter is flashing, the
machine is running out of power and charge the batteries immediately.
When maintaining the batteries, please wear gloves to avoid contact with acid substances.
Check whether the battery cords are worn and the connecting parts are loose, and replace them when necessary.
Keep the batteries dry and clean and make sure that there are no dust on them, since it is extremely harmful to the batteries
and may even cause them to burn in severe cases. Do NOT put any object (especially metallic object) on the batteries either.
In order to extend the service life of the batteries, charge them immediately when the cleaning work is finished. Deep
discharging is strictly forbidden for it will reduce their capacity and service life.
The correct steps of charging the batteries: first install the batteries, then connect them to the mains.
If the machine is not about to be used within a long period of time, please fully charge the batteries and disconnect the battery
cords.
