upvc window gearbox advice required
Went to open one of our upvc windows and only 1 of the shootbolts is working. I think it may be the gearbox. I have removed all the screws that are visible on the actual frame and can't see how to access the gearbox. It is a Saracen roller lock gearbox, does the actual glass need to come out? Or can anybody point me in the right direction to a diagram or YouTube video.
