3.5 Maintenance and disassembly of suction motor
●After the daily use of the machine, please discharge the sewage from the
sewage tank in time to prevent the water level from being too high, being sucked into
the suction motor and burning the motor.
●During the use of the machine, if there is too much foam, it is recommended to
use a defoamer solution to prevent the foam from entering the filter screen and into
the suction motor, causing the motor to burn out.
●Removal of suction motor:
The suction motor is fixed at the bottom of the sewage tank. Before removing:
1. Empty the sewage tank first, turn off the main power switch, and keep the
machine powered off;
2. Turn the sewage tank sideways and pull out the suction motor pair socket;
3. Loosen the fixing nut of the suction motor and take out the suction motor.
●Installation of suction motor:
1. Align the mounting holes of the suction motor with the screw of the sewage
tank, and then tighten it with a non-slip nut;
2. The installation can be completed by plugging the suction motor pair socket
with the machine line.
3.6 Self-propelled drive controller diagnosis and
disassembly
●The first-generation self-propelled controller is located inside the clean water
tank; the X4 second-generation self-propelled controller is located inside the handle.
Rated voltage: 24V; Output current: 60A;
●During the use of the machine, when the machine does not move, you can use
a multimeter to measure the positive and negative poles of the power cord of the
controller to check whether there is any voltage. When it is determined that there is no
voltage, it can be judged that the controller is burned out.
Disassembly and assembly of the first-generation self-propelled X4 controller:
1. Turn off the main power supply to ensure that after the machine is powered off,
the sewage is drained and the sewage tank is turned over.
2. Loosen the positive and negative wiring of the power supply, and drive the
positive and negative wiring of the motor.
! ! Warn
During the use of the battery, the capacity of the deeply discharged battery will
decrease and the life span will be shortened.
