on the car shell on the left side of the control panel.
Water Inlet
Caution: If the environment of the sweeper is below 0°C, the water in the water tank must
be drained. The drain valve is located at the front of the vehicle bottom.

remove the foreign matter.
Use the key switch to start the sweeper and observe the electricity meter to ensure that the
voltage is within the normal range and the electricity is sufficient to complete the operation.
Test run the sweeper, check whether the driving system (especially the brake system) and the
cleaning system are normal, and pay attention to whether the sweeper makes abnormal noises
during the whole process.

main brush front baffle pedal when the garbage comes under the vehicle, and then release the
pedal after the sweeper passes the location of the garbage.
Caution: Do not clean slender rope-like objects such as ropes and metal wires, so as not
to be entangled with the brush and affect normal operation.
