Default Preventive Maintenance on Saw Stop

I have had a Contractors Saw Stop for almost 3 year and have had two problems for some time. The blade goes up and down very hard. I called saw stop and they sent me a pdf of the gears that are the problem. I couldn't load the picture. They are by the adjustment for the blade height. Very hard to get at since I have the saw on a cabinet. I did clean out the gears with air and brush helped some but still quite hard to raise and lower blade. Other problem is motor makes funny noise sometimes when I turn on saw and getting more frequent. Turn saw off and back on and runs fine. Last week belt came off and when I went to put it on the motor was very hot. Took motor to repair shop was full of sawdust and start switch was not sliding do to sawdust build up.
1st picture saw on cabinet, no socks or skivies Vance.
2nd picture two set screws one was loose (made belt come off)
3rd picture cut hole in back of cabinet to access easier cleaning.
4th picture have rubber mat to help contain sawdust (have to lift it up to tilt blade.)
Last picture is outfeed table and vacuum hose.
Saw Stop Contractor owners check set screws and if your saw makes funny noises when starting clean motor. I have had a Craftsman 12" table saw since the late 70's no problems, but it was made in the USA not Taiwan.

cleaning the gears/mechanisms and dry lubing them may help...

This would have been the week that I'd have finished chewing thru the restraints...
If only new layers hadn't been added....

How did the motor get sawdust in it Larry? It should be a totally enclosed fan cooled (TEFC) design. If it's an open face drip proof (OFDP) that is the wrong application for it. In an OFDP you can see the windings. On a TEFC all you see is casing.

Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.

Not yet apparently. Interesting to see that this saw isn't as good as it's cracked up to be. Let's hope the difficulties can be solved.

OK, fess up...which one of you clowns stole my sig? It was right here a second ago.

In his post he listed pictures, I was wondering if he tried to post them and they didn't go thru.
As far as his post, I am surprised at these problems as I have heard about what top of the line this tool is.
I'm with Chuck, on the motor. This is the first negative post I have read on Saw Stop, other than marketing.

That's usually the cure. I had a Ryobi for several years and it would get gummed up with sawdust on the raise/lower mechanism. It needed cleaning about once a year. A lengthy job to do, more than an hour every time.

I realize you were looking for the pictures Herb, just as I was. Something went astray I guess. Maybe they will be forthcoming a little later.

I too am really surprised the motor doesn't appear to be a TEFC. That's a big negative for a tool that costs close to $5,000 in Canada.

Think we really need to see pictures of the cabinet.

My SWAG (Scientific Wild Arsed Guess) is the design of the cabinet and problems with air flow might be the culprit(s)

As for the Saw Stop Contractors saw motor, it is a TEFC. See:

SawStop | We are the contractor Table Saw of choice | SawStop

Since the belt came off, the first thing to check are the motor and arbor pulleys coplanar? If they are not, that could cause problems with the belts and motor over heating. Is the belt guard interfering with the belt?

As for blade elevation difficulty, is the lock knob on the elevation crank assembly working properly? Does it bind up/rotate freely? Agree with what Stick posted about lubricating and cleaning.

Before I posted article I had all the pictures in place. Don't know why they didn't appear.
I have used dry lube several times, no help,
The motor is totally enclosed.
