Step 3:

Bring the shoe up 3″-4″ and then turn the screw driver counter clockwise to bring the grove back to the “U” or locked position. Now you can remove the flat head screw driver as shown in figure 3.

Step 4:

Now bring the sash down to the level of the shoe.

Step 5:

Using the tilt latch, tilt open the window as shown in the figure 4. Please make sure that the sash is parallel to the floor.

Step 6:

Tap on the window near the shoe so that it sits inside the shoe.

Step 7:

Step 8:

Pull the sash UPWARD and check if the shoe has been engaged. If the shoe has been not been engaged, repeat step 4 to 7. If the shoe has engaged you will not see the shoe anymore and the window will function properly.
