BRAKES

☞
Note:
Switch the vehicle off in push mode. – This makes
pushing the vehicle easier.
The vehicle is fitted with a double security system, con-
sisting of:
– the drum brake (option),
– the motor brake and
– an electro-magnetic spring pressure brake (magnetic
brake).

MOTOR BRAKE

The function of the motor brake evolves by the type
of approach of the motor through the power electron-
ic.

FUNCTIONALITY

With retracted driving lever the induced motor volt-
age is short circuited by a programmable tacting fre-
quency that continuously brakes the vehicle down to
almost stillstand.
With the programmable tacting frequency the brak-
ing process can be adjusted from "soft" to "full-stop".
When traveling downhill the motor switches to gener-
ator operation. This effects that the energy won is fed
in to the drive batteries (energy recycling).
