The machine is equipped with an electrical panel that acts both as a control panel and as a container for
the protection elements of the electric motor.
The dashboard is positioned on the front of the machine at the level of the handle.
In this position, the machine is easier to turn on and off the machine, as well as keeping all the machine's
functions under control by means of warning lights placed in the dashboard in question.
In addition, the handle also acts as a protector for the dashboard which is therefore protected from ac-
cidental impacts that could damage the equipment and consequently make it impossible to operate the
machine.
