Operating Instructions

• For profile tubes:
For some drive adapters, tolerances of the channel widths in different roller tubes
can be balanced by turning the drive adapter in a different channel slot. These chan-
nel slots come in different sizes and make it an exact fit possible when the drive is
installed.
• For round tubes:
Release the tube from the motor died in advance, so that the cam of the ring can
also be inserted into the tube. The cam of the ring must not engage with the tube.
For rings without pulling cams, the roller tube must be connected to the ring by a
4.8 x 10 mm sheet-metal screw.
4. Assemble the tubular drive with the relevant ring (A) and drive adapter (B). Insert the
tubular drive with the pre-assembled ring and drive adapter into the tube as shown.
Ensure that the ring and drive adapter are correctly positioned in the tube. (Fig. 7)
The drive adapter of the tubular drive is connected to the roller tube as follows:
Attention
When drilling into the roller tube, never drill near the tubular drive!
The tubular drive must not be hit into the tube or dropped into the
roller tube!
Becker also recommends that the counter bearing be joined to the roller tube.
5. Hang the tube in the bracket and secure the motorhead piece in the drive bracket.
6. Hang the mounted unit consisting of tube, tubular drive and thrust bracket in the
bracket.
