Maintenance Instructions – Friction Stay Adjustment
The majority of opening windows are fitted with a friction stay which is a type of hinge that controls the opening of the window itself. This is factory set so that the window neither closes under its own weight or is overly difficult to open and close. After a period of time, the friction pad may wear making the opener loose in operation.
Take a small bladed screwdriver and turn the screw by half a turn clockwise. The adjustment should be made equally to each pair of hinges. If this adjustment is insufficient then carry on turning the screw in half turn increments until the desired amount of friction is achieved. If opener is very stiff in operation, turn the screw by a quarter turn increments anticlockwise until desired result is achieved.
NB: If you have difficulty in making the above adjustment, please contact your supplier for guidance.
