Tensioning the Drive Belt
The operator’s toothed belt has been opti-
mally pretensioned at the factory. During the
starting and braking phases of large doors it
can happen that the drive belt hangs out of
the profiled boom briefly. This, however, is of
no technical disadvantage nor does it have a
negative effect on the operator’s function
and service life. If the pretension of the belt
is increased, this can cause unnecessary
wear on the bearings as well as have a detri-
mental effect on the overload recognition
system.
Maintenance Instructions
The garage door operator is maintenance-
free. For your own safety, however, we
recommend that you have the door system
checked once a year by a specialist.
Airborne noise emission of the garage
door operator: at a distance of 3 m the
equivalent continuous sound pressure
level of 70 dB(A-weighted) is not
exceeded.
Description for operating
= See text part
The ilustrated part presents the fitting of the
operator to an up-and-over door. Where
installation differs, a sectional door may also
be shown. In this instance, the letter
O
a is
assigned to the up-and-over door and the
letter
O
b to the sectional door.

For other makes the clearance between
the door at its highest point of travel and
the ceiling must be at least 30 mm.
