Occasionally you’ll need to lubricate the lever and movable hardware, maybe twice a year. Using a conventional oil can rather than the newer aerosol lubricants will eliminate some extra cleaning.
When lubricating the jalousie mechanism no longer keeps the window operating, remove the glass slats. Unscrew the old jalousie hardware. Measure the frame. Replace the old assembly with a new one of the same size, but use your old slats.
