3f) Placing and
Tightening
the Toothed Belt
To tighten the toothed belt, first remove the cover cap on the drive (Fig.
8) and loosen the clamping plate on the door actuator. Now guide the
toothed belt around the toothed pulley on the drive and the idler pulley
(Fig. 9), shorten to the required length and secure it again on the door
actuator through the clamping plate (Fig. 10, Pg. 11).
To tension the toothed belt, move the idler pulley in the rail until the belt
is well tensioned. This must not hang slack in the system. Then secure
the position by tightening the idler pulley.
