ASSEMBLING THE 3 PIECE SEGMENTED RAIL
NOTE: For 1 piece preassembled rails, proceed to the next step “TIGHTEN THE BELT”.
NOTE: Not for use on J-type tilt doors.
The segmented rail is largely preassembled and consists of 3 parts. The carriage, push rod, release handle, the guide pulley and the lintel bracket with belt 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 belt.
2. Pull apart the two rail sections completely in order to create a gap for the middle section (C). This rail is designed in such a way so as to easily add the middle section. Slide the 2 connecting pieces (D) 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.

TIGHTEN THE BELT
Note: The spring must be able to compress and bounce during operation. Final tensioning can be performed after installation if necessary. Over tightening the belt may overload the system and cause excessive wear.
1.Tension the belt by adjusting the nut (1), on the pulley assembly, clockwise until the spring is engaged.
2.Continue tightening to compress the spring and remove all the slack in the belt. DO NOT OVERTIGHTEN but ensure belt is firm.
3.37-41 mm as indicated in the diagram is normal.

(3) and push down to install.
3.Secure the rail on the opener with two C-Rail brackets (4) and the screws (5).
This completes the assembly of the door opener to the rail.
