Well, that is one serious disapointment!

I purchased a Boss 15 less than a year ago, only used it about 6 times and it died on me today. It started speeding up and down, not by much but enough to be noticeable, then after I was done with a pannel, it no longer turned on when I tried to do the next one.

It has for sure less than 20 hours of work time on it, very very surprised after all the great comments I have been reading for years.

Will have to see if the service matches hit's reputation now ;(
 
Definitely contact their customer service... it's really one of the best in the business.

You should be in good hands with Griot's.
 
Did you try changing the brushes with the ones that come with the polisher?

No, but brushes don't degrade that fast. When I brought in my 6 year old Rupes for repair, I asked the technician about the brushes and he says they were like new. And that machine has polished hundreds of cars.

I believe Budget had an issue with his G21 and he change the brushes even though the weren’t worn and it worked again. Might just been loose connection but worth a shot

Yep...turns out that the brushes weren't truly bad, just needed to be 'reseated' so I took em out, swapped sides and was good to go.

Regardless, I called Griots and they sent me 2 new sets of brushes for free as backups...

Was weird, one minute happily polishing away, turned off, set down and next time I picked it up dead as dead could be.

Swapped brushes side-to-side musta reseated them, good to go.

Happened with less than 5 vehicles done with machine, very early on in its life.

^^^This^^^

And it is not unique to just polishers/Griot's. I have had to do this exact same thing to numerous drills (DeWalt, Milwaukee etc...) Makita rotary's, and a Bosch jig saw over the years.
 
I’ve hammered on my 15 for 3 plus years on a daily basis. Changed brushes once!
 
I bought a brand new GG3 about 5 years ago from the big auction site. And yeah, you could tell this tool didn't have a fingerprint on it from the factory, it was a great deal, considering $63 shipped.

It went to hell after about 15-20 minutes worth of use on very small areas, I was essentially just testing and toying around with it was all.

Got quite noisy and rough running. And I decided to tear it down, and take a peek inside.

Both Brushes were cracked in 1/2. The receptacles they sat in were recess sliding affairs, and evidently were never properly seated upon assembly in the factory. They probably slap these machines together in less than a minute's time at most.

And actual cost in Chinese moola, I'd say about $10-$15 tops at most.

Grease, tons inside, but gears were bone dry. Grease all over, but where it was needed to be. And evidence upon trial fitting that replacing with the pair of new Brushes that came with, the exact same would've happened, until I devised a way to help properly retain the Brushes in place upon re-assembly.

Took out all old grease, not that it was maybe inferior, but cleaned out the Housing Halves, re-lubed with Super Lube Teflon Grease at the Gears where it's needed.

All went together well, and ran smooth as butter after. Ran it in slowly at first, a few seconds, then 10, 20, a minute, on and on, to slowly break in and seat the new set of brushes. Still in use, runs like a champ.

This machine was so relatively easy to work on, and the effort and little time spent was worth it.

Great post. I also use SLT whenever I rebuild electric motor gear cases. :)
 
Could I have possibly voided my warrantee with Griots for doing this surgery on my GG3? Possibly.

But I would say any half wit technician, who would like to tear into my GG3 if it ever craps out again, seen what I done, plus I kept the pair of broken Brushes, I don't think I'd personally have a problem.

Working as a mechanic for Amtrak for 30 full years, working on and fixing multi-millon dollar equipment in and out, releasing trains with hundreds on board, private cars, presidential train sets, etc., I might be a railroad mechanic, but I surely was not a "railroader", who would railroad something to smithereens, and bugger something. I was one of the very best mechanics of my era-tenure, and although now retired have zero doubt that I could walk into that yard-shop tomorrow and still show up most the new mechanics.

What an old timer once told me when I was 18 and started working there. "What a man knows, your knowledge that you hold here at the railroad, no other man can ever come along and take that away from you".

Yeah, I always pegged you as a mechanic, Mark.

Certain things about your posts. Kudos from a (medically forced to retire) marine mechanic..... :)
 
Ok good to know guys, I find that super odd but I guess it's worth a shot. Thanks!
 
I'd maybe suspect that the OP's GG15 Boss woes were caused by the brushes beginning to stick inside their retaining slots, then eventually were making poor contact. That swapping and re-installing cured the issue you experienced.

Besides a GG-3 and a PC7424XP, I also have a relatively brand new GG Boss-15 D/A. Have only used it once sadly, but hope to get some more use from it. So far, mine's been great, and it is an awesome looking machine as well, so far zero regrets purchasing it right here from AG.
 
Calendyr - Hopefully it’s as simple as a brush issue so you won’t have any down time.

If it comes to it, I’ve got no doubt their customer service will take care of you. I had their 1st gen DA that after 10 years I noticed would spit out little oil dots onto the paint when polishing. They traded it out no problem for the current (3rd gen) 8mm machine, and even upgraded me to the long cord. When I was talking to the customer service rep, I had mentioned I had some sprayer heads that quit working - the box with the new DA had 4 new sprayers in with it.

Also, I bought their BOSS foam cannon when it first came out (and it’s been great for me). After learning of the new revisions they made, I contacted their customer service again to see if they thought I’d be well served to change the orifice in the one I had for even better foam - instead they sent me a prepaid label to send back the one I’ve got and they’ll just send me the latest version.
With no real complaints with the first revision, I feel kinda bad taking them up on the offer, but especially since I’m using a pressure washer on the low end of the scale (the often recommended 1600psi/1.2gpm Ryobi) I’m afraid the Fear Of Missing Out on how the Rev. 2 would perform is too much.

Bottom line - They’ll take care of ya. :) Looking forward to hearing what gets your 15 back in the game!
 
My GG21 stopped working a few months after I bought it. Took the brushes out, put them back in, been fine for over a year since.

I concur with your whole ball of wax in regards with Griots. I had felt that I didn't wish to "abuse" their fantastic customer service, and be just another straw in the camel's back who could or might abuse their first rate considerations of theirs towards their customers, whether real or not.

There's many great companies out there, Adams, Here at PBMG, Sonax, Carpro, way too many to list, and yep, Griots ranks at the top. Not only their customer service, but as well the products they sell.

I'm again so happy and content to be a member here in good standing. AutoGeek has been one of the best things I ever did for myself, interacting with all you great people, all the people at AG, McKees, Mike Phillips.

Oh, and when I'm done using my many tools, I "detail" them too, pull out a bottle of Carpro PERL, Blackfire Multi-Purpose Dressing, they get a wipe down, and put to sleep in their respective tool cases I have.

I'm happy as a Clam to be here, love you all! :-)
