The ball bearing cam blade guard mechanism sticks and needed some initial
force to get it started. Its ok once the downward motion get started but a
little dangerous to use that much force to get it going. None of the other
saw has this problem. Anyone knows if Bosch has a fix?
I own that model saw and do not have that problem. It's the most-used
tool in my shop but that's still probably only five or six times a week
stretched out over a year.
However... since I'm not an expert or trained on those saws or anything,
I feel that entitles me to hazard a guess.
Ya got the guard, the metal arm attached to the guard, the bearing that
the metal arm rides on, and the rubber baby buggy bumber that the guard
rests upon when it's... um, at rest.
I don't feel much force when I start the blade downward but I do feel
some, and it's from the part where that bearing has to ride up the step
on the arm that forces the arm down further so the guard retracts.
So, if there's something wrong with that bearing or with the part of the
arm that the bearing rides on, you're going to feel much more force at
first, and then after the bearing rides up that step, none at all.
Might that be it?
That is it, all the force is where the bearing rides up on the initial part
of the step up metal arm when is at rest. If I place a spacer between the
rubber baby buggy bumper and the bearing, its much easier to retract the
blade guard. Must be some adjustment out of alignment. Another person noted
the same problem at Amazon.com.
I had this problem right from the start. Bosch is aware of the problem
and will cover it under the warranty (at least they will here in
Canada). Don't try to fix it but take it to a Bosch service centre.
Mine has worked perfectly ever since.
