(The type of motor is shown on its metal rating plate).
It is possible to make a quick adjustment without removing the
fan cover: fully tighten the adjustment screw (turning it clockwise),
then slacken it anticlockwise by 1/2 turn.
Finally check the correct tension of the belts and the braking
time that, as mentioned above,
must be under 10 seconds.
16.3. Electric brake maintenance
The duration of the injection of braking current into the motor is set at origin and cannot be adjusted afterwards since,
as there are no parts subject to wear in the system, braking intensity does not deteriorate over time.
Therefore, if braking time is extended, check the tension of the belts only.
Not getting any positive result, please address to service centre.

16.2. Maintenance of the electromagnetic brake
As explained above, when the stop control is operated, the
flywheels stop in a time of under 10 seconds. If on models
equipped with a self-braking motor, with use, you notice this time
getting longer, it is necessary to adjust the brake on the motor.
For this adjustment, see also the instructions sheet supplied by
the motor manufacturer, attached to this booklet.
It is necessary to remove the fan cover and turn the adjustment
screw to reach the value of the air gap shown in the table.
(air gap = distance between fixed portion and rotating portion).
The value of the air gap is checked with a feeler gauge (see
fig.16-4).
