Installation
(suite)
5. Remove the garage door opener from torsion bar.
6. Drill 3/16 inch pilot holes at the marked locations. Drill through metal door rail plates if necessary.
7. Slide the garage door opener back onto the torsion bar until pilot holes align with bracket.
8. Tighten the 2 square head set screws on the torsion bar. For a hollow torsion bar, tighten screws 3/4 - 1 full turn
after making contact with the bar. For a solid shaft torsion bar, tighten screws 1/4 - no more than 1/2 turn after
making contact with the shaft. If installing on a keyed torsion bar, DO NOT tighten the screws into the keyway.
9. Secure the mounting bracket to the wall and to the garage door opener. Use the 14-10x2" screws to secure the
mounting bracket to the wall.
REMARQUE : Si les barres de torsion présentent un faux rond, il est possible que l'actionneur fonctionne en vacillant
légèrement. Ceci est tout à fait normal.
