We also recommend screwing the idler to the barrel.
Attention
Do not hammer the tubular drive into the tube or drop it into the barrel! The curtain can only
be secured using springs or rigid shaft connectors. We recommend at least three pieces
per metre of barrel.
Mount the assembled unit comprising barrel, tubular drive and idler on the box and secure the drive with a split or spring pin ac-
cording to the type of wall bracket fixing.
Position the barrel so that the roller shutter curtain can be attached with springs or fit the rigid shaft connectors in accordance with
the manufacturer's instructions.

For profile tubes:
In the case of some drive adapters, tolerances of the groove widths in different bar-
rels can be offset by rotating the drive adapter into a different groove recess. These
groove recesses have different sizes and allow the drive to fit exactly.
For round shafts:
Measure the lug of the thrust ring (X, Y). Then notch the tube on the motor side, so
the lug of the thrust ring can also be pushed into the shaft. There must be no play
between the lug of the thrust ring and the shaft.
To ensure secure torque transmission for round shafts, we recommend screwing the
drive adapter to the shaft (see the table below).
Attention! When drilling into the barrel, never drill near the tubular drive!

Assemble the tubular drive with the relevant ring (1) and drive adapter (2). If the ring
has several grooves, select the groove which is a perfect fit and push the ring (1) onto
the thrust ring.
Insert the tubular drive with the pre-assembled ring (1) and drive adapter (2) into the
tube to achieve a form fit. Ensure that the ring and drive adapter are secure in the
tube.
Lay the connecting cable
Lay the connecting cable up to the tubular drive, and fix The connecting cable and
any antennae must not project into the winding chamber. Cover any sharp edges.
