Thats the one I remember drinking. I used to go to the rugby club every saturday with my dad, I'd have one of those and a bag of crisps with the salt in a little piece of blue twisted paper in the bag. 40+ years ago!
I've got one of those, very pleased with it. You can adjust the laser how you want, its all in the manual. The light isn't much good unless you're working in the black hole of Calcutta, but it's a well made accurate saw :)
If you go to the stihl usa website, you can download a manual for an hs 75 which may be the same. The us site seems to be the only one with a manual download option, i found my chainsaw one there. Hope this helps.
