G100 vibrating but not spinning anymore?

[bob-e]

3 weeks old--used once. I broke it out today and it seems like any pressure I put on it stops it from spinning. I put a little mark on the top of the pad to make sure it wasn't an optical illusion. Seems like first time I used it almost no amount of pressure could keep it from spinning. It spins fine if I don't have it on a surface at all. Think something is wrong, or am I cracking up?

You are most likely putting too much pressure on, for removing defects you should be at around 15-20lbs of pressure on the head of the polisher.

Read this to help get and understanding, scroll down until you see the picture of the scale.

Hope this helps!!

I'll have to post a vid. It will not spin with hardly any pressure at all (less than 5 pounds for sure)

Wow, thats odd, post a video and we'll try to help.

Here's the vid. It's set on 4.25. How many RPMs should I see at around 5lbs of pressure? In the vid I go from barely touching to maybe 10 pounds max as judged by my scale. Maybe it's supposed to rotate this slow? Upside: I can see my reflection in my hand

That looks about right but let me go turn mine on and check...

Re: G100 vibrating but not spinning anymore?

You said about ten pounds were being applied?

Yeah at maybe 5lbs it slows to about 30 rpm and 10lbs about 0 rpm.

Mine looks pretty close to yours in the video, lets wait and get another opinion, but its looks fine to me.

I tend to agree... looks and sounds like its working as it should.

Thanks so much for your help. I worked on a carbon fiber hood today that was totally messed up and the G + 83 made it look worse, but that's a topic for another discussion. I'll post a new thread with pics of that.

It appears to be working fine. Remember, it's a random orbital, not a rotary.

Re: G100 vibrating but not spinning anymore?

Well I first thing I noticed is that the pad is not very well centered. That maybe a contributing factor. I know with my G100 if I dont have the pad centered and not flat on the surface I am working on I dont get much rotation ether.

If the polisher was set on the 5.0 setting, (it was hard to see the number), the it doesn't sound right, not enough power.

We've had a couple of brand new units that right out of the box didn't work proplerly and we sent them back.

From the sound and appearance of the G100/PC in that video, it didn't look or sound right to this person.

Here's a thread about the "Spinning" factor, see my comments on page 3


G100/PC - Should it be spinning all the time?
