Hi may148706, You need to use a screwdriver large enough to locate in both slots at the same time. If is will not shift you may have to use a punch for the initial release. Regards S
Thanks a lot ... I thought it needed a special tool! I can't seem to find a screwdriver with a head larger than 12mm and a small size handle. Any suggestions where to look for these?
Hi may148706 See if you can find a piece of flat steel the right width and use this with an adjustable spanner or grips. A coin might do the trick. Regards S
