If the door is jammed in a partially open condition refer to recovery instructious in envelope on rear of the door.
1.) Ensure grub-screws in tensioner are fully tightend, opening door slightly to reach rear-facing grub screw.
2.) Hold the R/H Pulley with the spanner and by turning upwards, align holes in spring anchor bush and spring shaft. Insert retaining pin fully into hole and remove spanner.
3.) Open door slightly, enough (approx. 10 – 15 degrees) to securely ‘wedge’ open with suitable (approx. 6″ high) packing, enabling the lift cables to become slack.
4.) Remove the cable retainer from the pulley to be replaced by unscrewing the fixing screw located on the inner of the spring mounting bracket, using an L-shaped small posi-drive screwdriver.
5.) Note the number of cable turns wound onto the pulley before tapping out the roll pin from the pulley using a 4mm pin punch and hammer.
6.) Tap the offending pulley off the end of the spring shaft before loosening the retaining screw and removing the cable.
7.) Refit cable onto replacement pulley, ensuring the previously noted number of turns are re-wound and the cable sits in the correct pulleys grooves, and secure by tightening the retaining screw. If the spring tension is released with the cable out of alignment the pulleys may be damaged and the door will not lift correctly.
8.) Rotate pulley untill the hole lines up with the hole in the spring shaft and tap the pin back into place.
9.) Remove the packing from under the door and allow the door to return to the fully closed position, with latches engaged.
10.) To release spring tension, grip R/H pulley with spanner and ease upwards until the retaining pin can be removed. Allow spanner to rotate downwards slowly untill the spring tension is re-taken by cables.
