CASEMENT WINDOW HINGE ADJUSTMENT PROCEDURES
NOTE: THESE PROCEDURES ARE TO BE USED ONLY IF THE WINDOW NEEDS FUTURE ADJUSTING.
1.The amount of sash that this hinge will compensate for is dependant on the ratio of the sash width vs. sash height. To calculate the amount of sash drag adjustment for any given window size, take the ratio of width to height multiplied by 1/16”.
Example: Sash size equals 24” x 36”, width to height ratio is .667. Total adjustment is .667 x 1/16 = .042 (approx. 3/64”)
2.To adjust the casement sash, first fully open the window. Next, slip the adjustment wrench (Truth part number 31887) onto the base of the stud, found between the support arm and the track of the lower hinge. Swinging the wrench away from the lock side window will decrease the amount of sash drag. The maximum sash drag adjustment is reached when the stud flats are parallel to the track. Note: turning the stud flats beyond parallel will not increase sash drag correction.
3.For severe sash drag, a similar procedure can be used on the upper hinge. Upper hinge adjustment is made by swinging the wrench toward the lock side of the window. Maximum adjustment may cause binding as the window is closed. Please use caution.
4.Stud may be adjusted with std. 3/8” wrench if support arm is removed before adjustment.
