I was confused by your response until I saw your location, Laughs are on me.
The upper saw guide is to help prevent contact by fingers. Not an absolute but it does help.
Last year I was making some toys for kids here in the states and I was breaking some rules for safe operation when I had a situation that could have been a lot more serious. I was making a few last minute cuts and was in a rush to get finished and did not have the top plastic guard in position. I finished a rip cut on a component and when I pushed the piece through and the cut was finished I lifted the piece clear of the table and brought it back to me. In doing so the piece, about 20" long and 4" wide, caught the top of the blade. I was holding the piece in my left hand. The piece spun around and hit me just below the rib cage and the pain in my left hand made me not want to look down. I thought that I was going to see my thumb missing>:eek:
Fortunately just a bad sprain and a very visible bruise on my abdomen about 12" long and 3/4" wide.
I was also home alone at the time and after I was able to straighten up I realized that it is not good practice to use high power equipment with no help around.
As I said before, I was lucky, some others may not be so.
Always use the safety guards. ( I do now).
I also insist that the members in our woodworking group ( I live in a retirement area) use the safety equipment but many of them will remove it because they think it is an inconvenience.
Accidents happen in a few milliseconds but the results may last a lifetime.
Again " Don't make red sawdust" it is the unofficial motto of our woodworking club.
