4.0 Daily operation and maintenance
Preparation work:
1) Choose appropriate detergent and detergent concentration according to the
contaminated state of the ground;
Generally speaking, only two cups of cleaning liquid from a disposable water
cup are needed.
The disposable water cup is shown in the right picture.

-9-
2）In the past, cleaner was added to the nozzle, and then clean water was
added to the water tank.
If you take water from tap with water pipe, you can insert the water pipe directly
into the water filling hole on the side of the machine, but you should pay
attention to the water level, so as not to overflow the cleaning liquid!
Starting working:
1.In areas to be cleaned, the ground should be cleaned first to remove larger
debris and dust. Make sure there is no soil, stone, paper scraps and other
debris on the ground before cleaning, which is of great benefit to you to
improve work efficiency and protect the machine.
2.Start the power switch lock, light the power indicator, check the battery power,
confirm that the power is sufficient, before cleaning operations can be carried
out; if the power is insufficient, the battery must be charged;
3.Put forward and backward switch into forward gear.
4.Start brush disc motor, water absorption motor and button switch
sequentially.
5.Adjust the flow of clean water (detergent) according to the situation of
washing land, move up and down the adjusting handle to control the flow of
water; it can clean the ground and reduce the loss of clean water
(detergent).
6.Start switch, brush disc motor, solenoid valve open, machine start to work.
Note: The adjustment of absorbent tape will directly affect the water
absorption effect of pickup. It is necessary to keep the uniform adhesion
between the pickup tape and the ground. When the tape is worn out, the
proper position between the pickup tape and the ground can be maintained by
adjusting the universal wheel knob of the pickup tape.
7.Because of the uneven ground, sometimes even after cleaning, if there is still
water, the brush disc can be raised, start the water-absorbing motor, promote
the washing machine, in the water area, repeated, repeated absorption.
There are deep grooves on the ground, which will affect the water
absorption efficiency of the machine and can only be treatedseparately.
8.Problems of Adjustment Squeegee: When you feel that the suction motor

-10

is suddenly abnormal during use, and the squeegee does not absorb water or
the sound of the squeegee is normal, the squeegee cannot absorb water, you
should stop the operation immediately for inspection;
①The water level has risen to the highest position (floating up cut off the wind
path),you will discharge sewage;
Method: Pull the sewage pipe out of the pipe clip, open the pipe cover, drain
the sewage into the sewer, and wash the sewage tank. (right picture)
②If the water level in the dirty water tank is not high and
there is no excess foam, please check the connection
between the suction hose and the hose, which is likely to
be clogged with debris here, and it will return to norma
after being cleared.
③If the water level in the dirty water tank is not high, but
there is a lot of foam, this means that it is possible for
your cleaning fluid to add too much or the cleaning fluid
you use is a high foam cleaning liquid.
④If the above three conditions are not, please pull out the suction pipe on
the suction pickup, open the motor of the suction machine, and use your
hand to try whether the suction of the air intake is normal, if the suction is
too small, check whether the suction connecting pipe is blocked.
9.Method of Replacing Brush Disk：
Loading brush：Place the brush tray to be placed under the brush cover (if
using the dial, please put the brush on the dial and then put it), and put down
the brush pedal so that the brush head and the brush holder are basically
opposite. At this time, press the control panel to brush the motor start button.
As the motor rotates, the brush disk will be automatically installed. You can
then start the operation or manually install it. For the unskilled staff, it is
recommended to install it manually.
②Unloading brush:After you finish your work, first raise the brush disc, close
the brush disc switch, the motor stops turning the brush disc by hand, and then
the brush disc can be removed.
10. Battery replacement method:
①Cut off all button switches and open the sewage tank.
②Release the clamp on the battery, remove the battery connection, and
replace the battery separately.

11.Maintain Squeegee：
Squeegee is an important part of floor washer. In the process of absorbing
water, because of the friction between adhesive tape and ground, it will wear
out. When the effect of absorbing water is not good, the following checks
should be made.
①Whether there is foreign matter in the rubber scraper;
( Prepare a towel and wipe the strip at any time)
②Whether there any debris blocking at the suction and hose connection；
( Remove the connection nozzle or remove the suction to clear the
blockage )
③Whether the angle between the scraper and the ground is suitable, it can be
adjusted by the squeegee universal wheel.
④Check the wear of the edge of the scraper. If the wear is severe and the
adjustment cannot be restored, the scraper strip can be used in reverse. If the
other side is worn, only the new strip can be replaced.
Normally configured is a common strip. If you are using it in a
heavily oily environment, please purchase a special strip for oil
resistance.
12. Work after the end of daily operation:
①Wipe the outside of the cleaning machine with dry and wet cloth.
The sewage in the sewage tank is emptied and cleaned.
Rise the brush disc and squeegee, and park the floor washer in a flat, dry
and ventilated environment without flammable gas, liquid or chemicals.
④If it stops using for a long time, it should be charged regularly to protect the
service life of the battery, open the cover, air-dry, and cover the floor washer
with dust-proof cloth for storage.
