5. For sensors mounted at a 45-degree angle,
using the linkage-forming tool, bend the linkage
at a 45-degree angle on the mark so the linkage
is parallel to the sash (Figure 12).

6. For sensors mounted at a 90-degree angle,
bend the linkage at a 90° angle on the mark so
the linkage is parallel to the sash (Figure 13).

7. Clear any obstacles between the sash and the
actuator with additional linkage bends.
8. Place linkage against the sash; mark an
approximate location to trim the excess linkage.
NOTE: When trimming off excess linkage,
make sure there is enough of a fork
to fit through the actuator. See
Figure 14 and Figure 15.
9. Using the linkage-forming tool, cut or score
location that will be broken off (Figure 14). Bend
the linkage back and forth until it breaks.

10. Clean the mounting area with an alcohol
towelette and allow drying.
11. Attach the linkage to the actuator car by
inserting it through the holes on the side of the
actuator car (Figure 15).

12. Remove the protective paper from the adhesive
backing on the mounting plate.
13. Close the sash; move the actuator and linkage
to your estimated mounting position.
14. Lightly press the mounting plate onto the sash.
NOTE: Make sure that the plate is mounted
so that the sash can travel without
running the actuator block off the
track or interfering with any
obstacles.
15. Adjust the mounting plate if necessary and firmly
attach the mounting plate to the sash.
