TIGHTEN THE CHAIN
Note: The spring must be able to compress and bounce
during operation. Final tensioning can be performed after
installation if necessary. Over tightening the chain may
overload the system and cause excessive wear.
1.Remove the transport lock (X) and ensure the chain is seated
on the gear wheel.
2.Tension the chain by adjusting the nut (1), on the pulley
assembly, clockwise until the spring is engaged.
3.Continue tightening to compress the spring and remove all the
slack in the chain. DO NOT OVERTIGHTEN but ensure chain
is firm.

The segmented rail is largely preassembled and consists of 4 parts. The carriage, push rod, release handle, the guide pulley
and the lintel bracket with chain tensioner are in the front part (A). The seating for the drive shaft and the sprocket are in the
rear part (B). Hardware items are placed in the rails during transportation - remove these. Lay the front and rear rail sections
one behind the other.
1. Remove cable ties that secure the chain. Leave the transport lock (X) still in position until instructed to remove it in section
9.
2. Pull apart the two rail sections completely in order to create a gap for the two middle section (C & D). This rail is designed in
such a way so as to easily add the middle sections. Slide the 3 connecting pieces (E) over the seams of the rail sections up to
the markings. To secure the connecting pieces,
bend the sheet metal lugs outwards with a suitable tool
. The assembly of
the rail is complete.
