Assemble bracket.

NOTE:

This new bracket is being added to the LA400, offering

greater mounting flexibility.

DETERMINE MOUNTING LOCATION

The gate post bracket assembly can be mounted several places

on the gate post.

Ideally, the distance between and opener hinge points should be

approximately 7" x 7". Place opener against gate post and adjust

the opener until the required dimension is achieved (Figure 1).

ATTACH THE OPERATOR

Secure brackets to post and gate with c-clamps. Attach operator

arm to brackets with pins and clips provided (Figure 2).

Disengage the operator by inserting the key and rotating the

handle (Figure 3).

Move the gate manually to the fully open and fully closed

positions. It is extremely important that the gate bracket does

not bind with the post bracket (Figure 4).
