Nobody is going to be stealing your FragraMatics shampooer brush unless they cut the hose. I actually think this is a little ridiculous. You have to take out the screw which you really don’t need (There is no way the hose is going anywhere). Then I guess you have to remove the outside metal piece (second picture). Then the hose needs to be unscrewed from the nut that it is mounted in. Oh and that is not fun!
I am starting to hate my Craftsman table saw (model number 137.218240). I needed to use it to cut some stuff and it would not start again. It was the switch again.
The first picture is the actual switch and the metal piece that completes the circuit. The second picture is what pushes the switch, I love all the saw dust.
