5. Attach sprocket with the smaller bore (1") to the

torsion bar making sure that the screws are on the

side closest to the garage door (Figure 3).

NOTE: Do not tighten sprocket at this time.

6. Place the chain on the sprocket located on the

torsion bar (Figure 4).

7. Attach the sprocket located on the motor unit shaft to

the chain. Secure the motor unit to the wall using the

hex head screws (Figure 5).

NOTE: Ensure that the chain is perpendicular to the bar

and not too tight.

8. Tighten both screws of the sprocket on the torsion

bar equally to secure the sprocket to the bar

(12-14 ft./lbs. of torque). Securely tighten set screw.

You may need to rotate the chain to make the

screws accessible.

9. One side of the chain cover will have an indentation

that will fit into the middle of the motor unit sprocket.

This side should be put on first (Figure 6).

10. Position the remaining cover over the other side so

that it encloses the chain and sprocket assembly.

The covers will snap into place. Secure them by

screwing them together using the 1/2" screw

(Figure 7).

11. Rotate chain to ensure smooth travel. Adjust, if

necessary.

12. Refer to Installation Step 2 of the owner’s manual for
