3. Use existing holes.
Hold the device on the wall and see if you can use exist-
ing holes, for example, those for the old belt winder. If
not, you must mark where the new holes are needed
and bore them.
4. Prepare the belt.
4.1 Cut the belt o approx. 20 cm under the mounting
position.
4.2 Fold the end of the belt over by approx. 2 cm and cut a
short slit in the centre. This enables you to subsequently
hook the belt onto the reel.
Recommendation
The belt must run as straight and freely as possible.
For sti roller shutters, mount a deection roller on
the belt box. This helps to prevent unnecessary friction
and wear to the belt.
