Part VI common phenomena and treatment methods
1. The brake doesn't workwell
Adjustthe nuts ofthe steel wire ropeinside the rear tires onboth sides clockwise until
the braking effect of both sides is the same.
2. No way.
The related components include controller (inside and left side of distribution box),
fuse (the second one from top to bottom), two-way contactor (under fuse), accelerator
(where right foot is trampled), driving wheel (front wheel), battery, corresponding
wiring segment, connector and clue. Any one of the components damaged or poor
contactwillcause nowalking,anditcanberecovered byreplacing thedamagedparts.
3. No cleaning
As for the main components of sweeping, there are 2 side brush motors, 1 main brush
motor, 1 fan, 1 100A contactor (in the middle of the right side of the distribution
box), travel switch (located on the right side of the car body, inside the main brush
connecting plate, fixed on the right side board), main and side brush push rods, wire
rope, control switch button, etc. If the travel switch is damaged or the adjustment is not
in place, the main brush push rod is damaged, the wire rope is broken, and the control
switch button is burnt out, it will not be cleaned. Side brush motor, main brush motor
and fan motor are controlled by 100A contactor. If any one of them does not work, it is
motor fault. If they don't work, the reasons are as follows

connecting section, and then wrap it with raw material belt and fix it tightly.
5. No charging
Check whether the charger connector is connected normally, whether the charger
works normally, and whether the display on the charger panel is in accordance with the
instructions. If the connector is not inserted properly, just plug it in. If you find other
