I guess this kind of washer should be behind the nut and blade as I mounted it now. Previously, the washer was between the blade and the nut. Therefore the blade was mounted the other way round, what made it almost impossible to remove it gently.

Had motor overload error on 2 wafers. Still able to use tool, but be careful when sawing the lower thirds of your wafers. -Robert From dkozak at snf.stanford.edu Tue Aug 16 03:11:46 2011 From: dkozak at snf.stanford.edu (dkozak at snf.stanford.edu) Date: Tue, 16 Aug 2011 03:11:46 -0700 Subject: Comment wafersaw SNF 2011-08-16 03:11:46: Loss of focus Message-ID: Camera went out of focus after one cut. Tried to re-focus, without any results.

After blowing it away, visibility returned. Not a problem on the machine.
