And then... There was a G8 (Polisher)

Troda said:
I unfortunately drew short straw. Mine arrived the other day. I spun it up with no load and the speed would oscillate. I switched cord but made no difference. It’s mist prevalent at speed 3 where you can hear feel a slight bump. It does all the same stuff loaded as well. Going to try and swap out the brushes. If that doesn’t work it’s back to griots.
In the recent past I’ve had a failed G9, a failed Adams SK micro, a broken shelf on my detail cart and now this. Can only go up from here.

My G8 had the same problems. The speed oscillated up and down fairly dramatically on speeds 1-3. It sounded like an engine trying to rev up but not quite getting there, as if the power was intermittent. There also was a bump on speeds 2 and 3 that you could feel and hear. I called Griot's, and they're exchanging the polisher for a new one.
 
Make sure that the cord is pushed in all the way. There are people finding out that it takes more force than what they thought for the cord to fully seat.

I had it in until it clicked, and I also tried the cord from my G9. The performance was the same with both cords pushed all the way in.
 
Just curious - The speed fluctuation is while polishing, or only with it unloaded in the air?

If only in the air I wonder if it's the digital speed controller trying to regulate RPM when it's expecting to need to overcome pad pressure.

It's been a couple months since I touched my G9 so I don't remember exactly what it was, but I remember the experience of cleaning pads via pad brush was different with the G9 than the GG6.

That's a good point you bring up, the tool running under load, versus no load?

Not sure what is incorporated inside these new 2 new machines from Griots, and whether they use such digital controllers as you say?

Does their manuals state such?

Yes, they both have digital controllers that increase power as the machine detects resistance from the user applying more pressure. To keep pad spinning at the same speed the machine increases power without the need to adjust the dial.

It happened in the air and then while polishing a test panel. The digital speed controller idea may be a possibility. The good news is that Griot's responded right away, and in exactly the way you'd expect them too. I saw enough to know that once the kinks are worked out, the G8 is going to be an amazing tool.

Update: Griot's sent a replacement G8 and it works perfectly. None of the problems in the first one are present in this one.
 
Hmmm. I emailed 12/22 again 12/27 called 12/31 received email with call tag 1/3 . Received response to original email on 1/6 Sent email expressing displeasure. 1/7 received email stating holiday makes for delays, sorry.

I would call customer service directly instead of emailing. I had a good experience that way. It speed things up if you've ordered directly from Griot's.

The 3rd date on my post is 12/31. That’s the day I called. Received emailed call tag several days later. The buffer is on its way back to griots and should be there tomorrow. I asked them to pull the replacement out and test it before they send it. Hopefully they get it out quick and it’works
 
Mine gets delivered tomorrow. Looking forward to testing it out.
 
Mine broke yesterday. The trigger lock button popped out. It just shot out. I tried to push it back on, but then it got stuck in the lock position. It wouldn't stop spinning so I unplugged it. Now it doesn't work at all. GG said they will send me a shipping label for replacement. The button is plastic on a threaded screw. It's a weak point.
 
Received mine today. Definitely looks like a nice machine. Feels solid. I can’t wait to use it.
 
I should say I used mine for about 3 hours. It took out a deep scratch on my Harley. I have to agree with others it struggles below setting 5. I have a dove tail fender and it had a hard time with the contours on setting 3. It polished my bike. I'm sure I can do headlights with it. I know GG will take care of me. Despite the set back with the trigger lock button it's still a good price. I'm sure GG will get it dialed in. I'm not ready to go $300+ for a really good one. I'm not knocking it. I'm impressed with GG customer service.
 
My replacement is a day away from me. Hopefully they tested it before the shipped it to me
 
Got mine today. Trigger would stick on almost as if some debris was caught in the housing. I kept working it and it eventually it loosened up. All of the issues with the last one are not present in this one. Going to put it to work tomorrow. Fingers crossed.
 
I have no stalling issues below 5, but I don't cut below 5. I polish on 3 or 4, and 3 to apply lsp, if not using a coating.
 
GG is sending out my replacement. They didn't waste any time getting the new one on it's way out to me. I have some chrome and a set of headlights I can get it going on. Can't wait.
