INSTALLATION

STEP

3

 

 

Attach

the

Rail to

the Header

Bracket

 

NOTE: (Optional) With some existing installations, you

 

may re-use the old header bracket with the two plastic

 

spacers included in the hardware bag. Place the spacers

 

inside the bracket on each side of the rail, as illustrated.

 

• Position the opener on the garage floor below the

 

header bracket. Use packing material as a protective

 

base. NOTE: If the door spring is in the way you'll need

 

help. Have someone hold the opener securely on a

 

temporary support to allow the rail to clear the spring.

 

• Position the rail bracket against the header bracket.

 

• Align the bracket holes and join with a clevis pin

 

5/16"x1-1/2"

as shown.

 

 

 

 

• Insert a ring fastener to secure.

The Sears 139.53915D is a significant addition to the lineup of garage door openers, blending both functionality and modern technology to enhance user convenience. This model is designed to accommodate residential garage doors, forming a reliable solution for homeowners who prioritize safety, security, and ease of use.

One of the standout features of the 139.53915D is its powerful motor, capable of handling heavy garage doors with ease. With its 1/2 horsepower motor, it ensures a smooth and swift opening and closing mechanism, allowing for quick access while still maintaining durability. This strength is particularly beneficial for larger or heavier doors that require more power for reliable operation.

The opener utilizes a chain drive system, renowned for its durability and strength. Chain drive systems are highly effective in providing reliable performance, making them a popular choice for various households.

This significantly enhances security by preventing unauthorized access and ensuring that only designated users can operate the garage door.

Additionally, the model features a safety reverse system, which automatically reverses the door's direction if it encounters an obstruction while closing. This not only protects vehicles and other possessions but also safeguards pets and children—an essential component for family households.

Installation of the Sears 139.53915D is designed to be straightforward, with comprehensive instructions that facilitate an efficient setup process. For those who prefer a seamless experience, the opener is compatible with several accessories, including smart home technologies. This compatibility allows users to integrate their garage door opener into a broader home automation system, providing added convenience and control through smartphone apps or smart devices.

In summary, the Sears 139.53915D garage door opener is a robust, reliable choice for homeowners seeking an efficient and secure opening mechanism.
