Power Switch:
When the switch is placed in "O", it is in the power
off state;When the switch is placed in "-", it is in the
energized state. At the same time, the red status
indicator beside the switch is on. At this time, the
vehicle can be started as long as the accelerating
handle is rotated.
Reset Switch:
On the left side of the bottom is the reset button of
overcurrent protection switch. When the scooter
exceeds the set current for some reason, the
overcurrent switch pops up and turns off the power
supply of the whole machine.Press the reset button
and the overcurrent switch returns to normal.
Speed Control:
Adjust the speed by twisting the Angle of the
handle. When the handle is in its original
position, the vehicle will stop.When the direction
of the arrow to twist the speed control handle, the
vehicle is moving forward, let go of the speed
control handle, the vehicle is walking slowly by
inertia.
Brake Handle:
The principle of combining the mechanical brake
system with the electronic brake is adopted.
When braking, the brake lock drives the wheel
hub to brake. At the same time, the brake hand
closes the micro switch inside, and the controller
stops the output voltage (motor power off), which
makes it easier to brake.
