5 Conversion instructions
1. Please remove all parts from the packaging and check you have all the required parts according to
the parts list.
2. Remove old drive motor and selector of old door operator (Caution: do not remove the old buffers,
you will need them).
3. Remove long lever with attached counterweight up to pivot point.
4. Mount TSG drive on the combi-bracket.
5. Mount the TSG roller on the second combi-bracket.
6. Mount the TSG coupler on the fast panel. Caution: do not drill into the trailer wheel track!
7. Mount combi-bracket with TSG drive under the door bar. Caution: the combi-bracket has to be
mounted as far outside as possible. So the panel can open completely and the clamp for the toothed
belt does not touch the toothed wheel on the TSG drive.
8. Mount combi-bracket with TSG roller. Caution: the panels have to be opened and closed completely.
Ensure the clamp for the toothed belt does not touch the toothed wheel on the TSG drive. The
alignment of the motor pulley and divertor pulley is important; please make sure that the alignment is
correct and in line!
9. Mount TSG end stoppers on the combi-brackets and adjust to approximate position.
10. Test the movement of the panels. If necessary correct the position of the mechanical components.
11. Fit the toothed belt, connect to the belt clamp and tighten with the tension device on the combi-
bracket carrying the idler pulley.
12. Mount the big plate on door operator using the old holes and buffers. Mount the plate horizontal and
in good order!
13. Connect new lever with axis and screw on big plate. Mount the lever horizontal and in good order!
14. The length of the lever has to fit on the clearance of the door. Close the door and close the coupler
(perhaps with a lace or something else). Hold the new lever on the existing lever and make a mark,
then drill a hole. After that connect both levers so that they can pivot. If the big lever is too long cut it.
15. Carry out final adjustment of the buffers.
16. Please refer to the TSG instruction manual enclosed for information regarding the set-up of the elec-
trics.
