How to Adjust a Hinged Window: Adjusting Casement and Awning Windows

For this project you’ll need safety glasses, gloves, and a Milgard adjustment wrench.  Contact Milgard to purchase an adjustment wrench.  If window is accessible from the exterior, check window for uneven sightlines or basically if the spacing between window and frame is inconsistent.  This will show you how much to adjust your window.  Remove screen, then fully open the window.  Next, slip the adjustment wrench onto the base of the stub, found between the support arm and the track of the lower hinge.  Rotating the wrench away from the lock side of the window will decrease the amount of sash drag, or the part of the window connected to the glass.  The maximum sash drag adjustment is reached when the stud flats are parallel to the track.  For severe sash drag, a similar procedure can be used on the upper hinge.  Upper hinge adjustment is made by rotating the wrench toward the lock side of the window.  You’ve reached the maximum adjustment when the stud flats are parallel to the track.  Close and open window to ensure you have made the proper adjustments.  Go to the exterior window and ensure that the spacing between the window and the frame is consistent around all corners.  If sash side spacing is incorrect, then adjust both top and bottom studs in the same direction to move sash left or right.  Adjust as needed until spacing is correct.  Once the window looks correct, put the screen back into place.
