I have replaced the handels & gearboxes on th upvs windows as the previous owner never opened them and they were stuck.
I have them working now 100% but when i close the window and try to pull the handle down to lock it the force to do so is very very hard/tight.
If i remove the metal keep that is screwed into the window the operation is like it should be,nice and smooth.
Please advise what i need to do to the metal keep in order for it to be working correctly.

Thanks

on the window mechinism there are rollers these can be ajusted using allan keys they need to be turned slightly to achieve the correct tension and grease it well once finished
