If you originally had the Getty type operators on your casement window, then installing our 39-077 might present a problem. Your window was designed to go with the Getty operator specifically. One idea would be to manually operate your casement window with the operator removed. That way you can check to see if it still opens and closes smoothly. If you still have problems, then the operator isn't the problem. You could possibly use some type of spray lubricant on the tracks and hinges to help it. Your window tracks and hinges could be the reason your operators don't last long. |
