Today(I know it is Sunday) I wanted to make some 13/16 dado cuts. When I got all the blades on and started the motor, there was a destinctive squeek when I cranked my PM2000. My first thought was that i maybe did not tighten the arbor nut enough. I tightened it and it still had a squeaky start. Thinking that the weight of a large dado might be the reason, I did not get too concerned.
After I finished the dado cuts(4), I put on a thin rip blade and thought that I would not get the squeak. Wrong. Although it was noticably less it was there just the same. Before ci contact PM, I thought I’d ask if anyone has experienced that with the 2000 and, if so, what to do about it.

Have you checked the belt tension?

That is what I expect it is. Darn thing is practically new, I am not in the mood to get out my manual this early and start "fixin" things
Nice to see you again.
Cool
Hi; good to be back!
I can save you digging out your manual, here's the belt adjustment part.
Drive Belt The saw is equipped with a poly-V belt. Referring to Figure 16: To adjust the belt tension – loosen the hex nut (B) on the motor pivot and hex cap screw (A) on the bracket with a 19mm socket or wrench. Pivot the motor (C) and bracket to the right to increase the belt tension. Retighten both screws (A, B). ------------------------------------

Old mechanic here Belts streatch! A fact of life.. Sort of like a wife gettin pissed at you on your first day of marriage!
You're right belts do stretch. In fact it is inhrent in all belts kept tight enough to do the job.
It is awfully early for my 2000. I bought it around the first of the year and I am not running a production shop.
My main suspect when I first posted was the belt and that suspicion is growing. I am going to start the motor today without any blade and see if I hear it. Putting a 3/32 rip blade reduced the level that I was getting with that big dado.
Thanks
Cool
I was going to get a PM 2000 this year (or a Grizz) but Uncle Sam took away all my money I had saved for it! Emergency roof repairs. Took me over the limits! And I ended up paying more than half the cost of the roor in TAXES! OK so I may get back 600 or so with the 'GIFT' from the good old USA! Not received yet!
Will, when your ship comes back in, I can endorse the PM2000. I am thinking my squeak problem is the belt and a little adjustment will be the ticket. I am really enjoying mine.
Cool ,
Before I did anything I might just try a dab of belt dressing , same kind used on automotive belts , some is available in a spray can , if the noise goes away you got it . Or take the blade off and see if it still makes the noise . If after adjusting the belt tension it still does it then take the belt loose or off and turn the motor on to see if it could possibly be the arbor bearings .

Hello Dusty!
The PM2000 has a poly v belt and belt dressing can cause premature failure in poly belts.------------------------------------

Hey D ,
Thanks , I was not aware that dressing would cause damage . Honestly I have never used dressing on any shop machines but thought the OP could instantly hear a change in sound like on a car belt .
Sounded like a tension issue not a worn belt .
Has business come back yet up North ? , we are just starting to come to life down South here , certainly not like the last 7 or 8 years have been.
Hope you are doing well , The White water trip offer is still open in a month or so when it warms up a bit so even if you are just traveling through it would be my pleasure and a fun day for sure .

Hey Dusty;
Business is balls to the wall one month and slow the next. I took on some contract machine maintenance and some computer consulting to smooth out the ripple.
When I was 17 I had a corvair and the fan belt wrapped around three sides of the motor, I used a lot of belt dressing trying to keep that mess quiet!
Thanks for the offer on the water trip, I'm hoping to have some free time this summer.

Funny D , I had a 1964 Corvair Monza when I was 17 also my belt never once came off but there was a never ending oil leak and one time on damp pavement the car did a 360° spin in an instant another Corvair trait . My next car was a 62 Porsche S 90 , wow what a ride it was jet Black and originally purchased in Germany so it had kilometers not mph . Whoa every now and then on the hwy I would look at the speedo and freak when it said 105 .
This winter was the worst period in the last 30 years for me , bout bled me dry , so when you are hungry you tend to take on jobs that may not normally be accepted , oh well . I'm doing a paint grade flush inset job for a retired engineer , he is a great guy but way too cerebral and tends to overthink and he requires a lot of time to become informed and make decisions . He held me off from starting for like almost 4 weeks . Now the painter is almost done and only part of the cabinets are set , I'm actually right on my time line as promised .
lets stay in touch d
A continuous squeaking or just for a few seconds when you first turn the saw on?
John White
Half second or less just at startup. Not as much with a thin kerf blade as with a dado.
That would suggest a belt slipping. Another source for squeaks is the blade rubbing against the sides of a zero clearance insert or on occasion a rubber seal on a ball bearing making noise. John W.
John..
My current Ridgid will do that sometimes,, Blade vibrates like crazy when turning 0ff the saw! I do try to keep my saw clean! As in squeeeky clean! I even use a tootk brush to get the sawdust out of the ridges on the belt! Still happens! Next day quiet as a mouse! I have no idea why!
Even when it does that I still get accurate cuts? Gremlins?
Blade vibrates??? Do you mean the saw vibrates? If it is the saw, a new linkbelt may be the ticket. If the blade vibrates, IMO you should call Sanford and Sons:-)
John,
This afternoon I put the 13/16 dado back on. When I took my saw blade off, I started the motor from dead stop three times and could not hear even a hint of squeak. I put the heavy dado on and I got at least a full second squeak. Seems like it is a belt issue. What do you think?
My PM2000 does the same thing every now and then. It seems to go away on its own. My shop is in an unheated garage, so the temperature may have something to do with it. I haven't really worried too much about it since it doesn't happen all the time.
I have "tinkered" with mine in several different setups and I am convinced that the belt is lose. The instructions for adjustment is quite simple. However, getting to one of the two nuts for adjustments is really tight and I am going to have to get a socket just for this job.
