HESE 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.
