Installation

9 Connect the door arm to the trolley

OPTIONB SECTIONAL DOORS

IMPORTANT: The groove on the straight door arm MUST face away from the curved door arm (Figure 1).

9.1B Close the door. Disconnect the trolley by pulling the emergency release handle.

9.2B Attach the straight door arm to the outer trolley using the clevis pin (H14). Secure with the ring fastener (H19).

9.3B Attach the curved door arm to the door bracket using the clevis pin (H13). Secure with the ring fastener (H19).

9.4B Bring arm sections together. Find two pairs of holes that line up and join sections. Select holes as far apart as possible to increase door arm rigidity and attach using the bolts (H15), nuts (H20) and lock washers (H21).

9.5B Pull the emergency release handle toward the garage door opener until the trolley release arm is horizontal. The trolley will re- engage automatically when the garage door opener is activated.

NOTE: If the holes in the curved door arm and the straight door arm do not align, reverse the straight door arm, select two holes (as far apart as possible) and attach using bolts (H15), nuts (H20), and lock washers (H21). If the straight door arm is hanging down too far, you may cut 6 inches (15 cm) from the solid end.
