Assembly and Installation Guidelines
Assemble the door arm by fastening straight and curved sections together with clevis pins and ring fasteners. Attach securely to the trolley and door bracket.
3.1 Assembling the Door Arm
Begin by assembling the door arm, ensuring the straight and curved sections are securely fastened together using clevis pins and ring fasteners.

Proper alignment of safety sensors and door arm sections ensures smooth operation. Adjustments should be made carefully, following the manual’s step-by-step instructions to maintain functionality and safety.
4.1 Aligning the Safety Sensors
Aligning the safety sensors is crucial for proper garage door operation. Clean the sensors with a dry cloth and ensure they are securely mounted.

Regular checks ensure optimal functionality and compliance with safety standards like UL 325. Proper alignment prevents accidents and ensures smooth door operation.

Performing a monthly safety sensor check is crucial for ensuring your garage door opener operates safely. Start by visually inspecting the sensors for dirt or obstructions. Clean them gently with a dry cloth if necessary. Next, test the sensors by placing an object, like a small box, in the door’s path.
