Daily Operation and Maintenance of the Washing a.chine

Battery

_ Attention: _The battery is very heavy.

Install two 12-volt maintenance-free batteries. The new batteries shall be fully charged before being first used. The new batteries can be fully charged and used for five times.

1. Pluck the hose(20,21) out from the sewage tank. (19)
2. Make sure the sewage tank is empty before lifting it up.
3. Place the batteries on the tray and adjust their position.
4. Connect all cable connectors well.

Attention: Be sure to connect the red (+) terminal to the positive (+) terminal and the black (- ) terminal to the negative (- terminal. If the connection is not correct, the machine will not run.

Failure to operate following the above rules shall cause damage to the batteries and even have the risk of explosion. Apply some protective lubricating agent to the battery pile and place the electric wire terminal protection device on all the electric piles.

Battery Charging

_ Attention: _Use only the native battery charger designed with this machine, otherwise the batteries shall be damaged.

Remove the sewage tank from the washing machine and cut off the power source on the control panel. After that, connect the charging plug to the battery socket of the battery terminal.

Filter body (k), filter (L), sealing ring (m), plug (n)

Operation of the Washing Machine

Water Suction Operation

1. Make certain the squeegee is in the downward position.
2. The squeegee will draw the detergent into the sewage tank when the washing machine is moving forward to brush the floor.
3. If necessary, rotate the knob (8) to adjust the voltage of the squeegee. (Do not make the angle of the red rubber sheet of the squeegee too big. Otherwise the red rubber sheet will be worn more quickly, which shall affect the cleaning situation. The greater the angle is bending, the greater the resistance will be.)

If areas need cleaning are missed, please decrease the use quantity of the cleaning solution and lift up the squeegee to pull the washing machine back to the missing areas. Lower the squeegee and move it forward to draw the remaining cleaning solution on the floor.

What Should We Do When There Are Too Much Foam in the Sewage Tank
