Make sure the sash lock handle is completely disengaged. Turn the crank slightly, and apply slight pressure to the sash near the lock assembly. The sash should snap open.

Then open the window and remove the arm bracket from the operating sash by unscrewing.

Next, remove the wood trim sill cover carefully, take care not to damage it when prying it up.

With the sill cover off, the operator should be exposed. Remove the remaining screws and lift the operator out.

Reverse this process to install the new operator.

To keep the window operating smoothly, clean the window track occasionally with a brush. To help prevent the sash from sticking, apply a thin layer of paraffin or other dry lubricant (Slider Slicker works well) to the weatherstripping. Do not use oily lubricants; they attract dust and grime, which will eventually restrict the window's movement.
