Tension of the toothed belt11.1
The toothed belt of the operator boom
is tensioned optimally ex-factory.
With large doors it is possible that the
belt will briefly hang out of the boom
profile during the start-up and slow-
down phases. However, this does not
constitute a technical malfunction and
does not negatively affect the function
and service life of the operator.
