- It's been a trusty tool for sure, years of faultless service. This trusty old Makita rechargeable angle grinder has been showing it's age recently & yesterday, after hours of work finally gave up the ghost completely.
Been the inquisitive chap that I am I wanted to take a look, just so I know what cause the demise of this old friend.
A quick tear down, visual inspection & some simple testing soon identifies the problem.
Watch out for the follow up video showing the repair & testing of this most excellent power tool.

*Love it. Name brand. good quality. **MyBest.Tools** great price. should have included the arbor but they never do.*
Great hearing and watching you, "Salvageable" EXACTLY! I'm same way, get joy out of getting to the failure and repairing without cash is the funnest for me.
Been using mine 10 years no trouble, just thinking maybe check the gearbox lube, and found your very enjoyable presentation.
I've modified the new 5 amp batteries to fit all my older tools, so I'm watching the heat on extended duty.
thanks Brother!
The armature coming out and not hanging up on the carbon brushes was a clue. The brushes should be removed first when cleaning or repairing other parts.
Great video Andy, I've had to replace the brush holder in mine to. Genuine part from Ebay and it lives again.
Yep, I picked up Genuine parts from a Makita distributor yesterday - NZ $30, new tool was $300 so a huge saving :-)
Great Video they are a great little grinder. I like them because although they are not the most powerful they are so easy to repair. I have fixed quite a few of them.
Excelente video amigo al desarmarlo y ver su estructura interna
Those Metabo grinders are damn good. I worked in a fan shop and we had a whole stable full of them. They will eat disk after disk and keep on chugging. Tripped the thermal over load giving all they would suffer and they always came back to life.
Side note: I have always heard Metabo pronounced with a long O (boat) not the double oo (book)
Those are the real deal, but nowadays you can't easily find a genuine one. You pronounce it me-ta-bo literally.
@@ruikazane5123 where does one buy the real ones and not the chinese ones?
@@snorttroll4379 can't really be sure these days. Just as how in Japan, some Sony devices are made in Japan but when you buy the same thing overseas it's made somewhere else. Might be worth checking the manufacturer if they have official sales channels or dealer networks (as how it goes with bearings) to at least have less chance of a fake...but if the manufacturer itself makes them over at China you're out of luck
I have exactly the same model as you and I've been using it for 3 years now. Hopefully, it still works for 10 years more
remember to take it apart and do some maintenance on it.
brilliant
Lifes been a grind, hundreds of slipped discs have taken its toll, i've lost that spark and just cant cut it anymore.......rip
"met a boo" haha
Good video, bloody good grinder.
A word to the wise to all out there, as soon as a power tool plays up, pull the brushes out and have a look.
Most of the damage is done by the arching if you continue to use it after the first signs of a problem.
Metabo is good stuff. They also do cordless grinders. All there grinders have a good reputation.
cutting locks with lawful excuse love it . i had bosch for about 10 years was gutted wen it gave up
Yep, the old Bosch power tools were good, I had a few (left them in the UK unfortunately)
BIG 10 day fabrication mission starting tomorrow!!
Cheers Andy
How do change the pining gear on that mikita 18v grinder dga452 you just show please.
Nice grinder, awesome girls)
I bought the dga504, its pretty nice, but its too heavy for one-handed work... 2.7 kg (with battery, shield and disk) - is not a joke. Now thinking about DGA452, its much lighter. Sorry if i do mistakes, i am from Russia)
Amigo gracias por kompartir preg donde consigues makita a buen precio gracias
How i wish i can have my own cordless grinder made from good country..from Philippines. Nice grinder
i have a makita 9557nb the thing is awsome
Hello Andy from down south in Christchurch NZ, I too swear by Makita and have been abusing the 18V brushless grinder model DGA506 for years. Im in heavy mechanic work and abuse mine with cutting more than I should and flappy/grinding disks most days and it somehow survives (chugs through a 5amp battery in no time on heavy work though) If your brushed one does finally give up the ghost ild highly recommend upgrading to the brushless Makita grinder. Keep up the great videos mate.
Cheers Dale. Thanks for the info on the brushless one. I'm in discussions with Makita NZ for sponsorship on the channel so hopefully I may get one for free :-)
Cheers Andy
Hi Andy typical dad always has to try out the kids toys on Christmas day but your just testing the toys first lol 🙌😀😀😀👍
Haha! Now that's a great way of looking at it! Cheers Andy
i have the new makita brushless grinder. it is super powerful and awesome
That's next on my list :-)
@@AndyMechanic you will definitely like it
As I used to say "it's deader than a dead dingos dongar" 😂😂
Check you’ve got power to those brushes before you start ordering parts.!!! 240v makita grinders are generally bullet proof, if you found it under powered from the off !! It may have been faulty new!! 5” disk without a gaurd !! Means watch your grip and your knuckles!!! Also leaning on a grinder means it pulls slot of amps and heat before it bogs, I have that same model and found that little battery/ motor protection module to be the weak link.!!!! Blowing grinders out with compressed air now and again keeps that “ CRUD” build up down to a minimum but you really should pull them apart and do a bit of preventative maintenance now and again..!! My biggest gripe with modern power tools is the cost of parts/ especially brushless units which generally aren’t worth repairing once the motors or controlllers fail…..( Makita Dss680. BL - £180. Control box/stator £120. Madness!!!
Interesting info, Thanks for your time contributing. I was lucky, new brushes and back working again :-)
I have this exact model. Fully charged batteries and the makita keeps cutting out if I apply mild cutting pressure and the red light flashes and it shuts off. Cannot make any serious cuts. Whats they problem u think?
I think it's most likely that your battery pack has lost capacity. The slight load is pulling the voltage down & that's what the Tool is sensing to trigger the red light. I had the same issue when I used an old battery. I think it's time to buy new one & make it a genuine Makita battery as it'll work & last much longer than the cheaper aftermarket brands.
Cheers Andy
That just showed the quality and proper design. Not only that cordless tools aren't really designed to be used like full-on mains. If you regularly checked the brushes you may haven't experienced this problem, though.
Very true. Tool maintenance is often overlooked.....exactly what happened here.
I completed the repair video today so should be up on the channel sometime soon.
Cheers Andy
Andy Mechanic But it lasted 13 years without intervention! Hehehe
Sure did! :-)
Amigo donde compraste la pistola d impacto d1/2 makita el modelo 1001 estoy batalla do p encontrarla y más made in Japón
Wow. It's halfway home to being an antique
You let that run for too long on worn out brushes, that is what caused the arcing. Having been in metal bashing for forty odd years I have found by trial and error that Metabo power tools are the only ones that last, back in the 70's Wolf were very good and Scintiller were best but Bosh took them over and slowly they became Bosch branded and absolute crap. So if you go shopping for new tools get Metabo.
Definately used it for too long! Wolf was awesome.
Fix video coming soon! Cheers Andy
Greetings brother, just wondering if that Makita Grinder your presenting here uses the same battery Makita is selling today...if so then Im switching to Makita Cordless tools, because that tells me about the company, and how they make products that interchange no matter when we buy them.
Hi, Yes, same lithium ion batteries on their current tools - I'm very pleased with all of their tools I have & they have great parts supply & usually easy to repair too.
Thanks for your support & comment
Cheers Andy
@@AndyMechanic Great to know, Thank you kindly.
Interesting video...looking forward to the follow-up video.
Cheers Steve, filming the repair this morning :-)
AVE is Awesome 😀👍🏼
I'm a Kiwi in NZ, so Hello
Hi Geoffrey, great to hear from you. Hope you find the videos helpful. Cheers Andy
@@AndyMechanic yes i really did and a few other videos later I've decided to buy a $350 makita grind not the $220, I'm also a mechanic based in auckland and one day moving my workshop to paparoa.
Excellent, good luck with your future business. Cheers Andy
If you like bright lights try Welding
i have old corded metabo grinder thats 25 years old orginal brushes and it have been used and abused and still keeps running. if you going to buy grinder buy metabo everything else makita milwaukee dewalt bosch ect
Agreed!
Please help me.
I also have a MAKITA BGA 452, but I have a problem.
When the machine is running, vibrations are felt, the whole machine shakes, but when I squeeze it with my hand in the middle or near the end, the vibrations are reduced.
Do you know why this happens?
I replaced the brushes, the other parts look good.
I tried the machine and without the head, the vibrations are felt again. So there is a problem inside the machine itself (rotor or whatever).
PLEASE HELP IF SOMEONE KNOWS OR HAS HAD A SIMILAR PROBLEM.
Greeting
Hi, it sounds like the armature may have become out of balance. Maybe a winding has shifted or, somehow, it has become bent? You'll have to pull it apart & inspect closely for any tell tail signs...
@@AndyMechanic
I discovered the problem. The controller is faulty. I'm out of luck, repairs are pretty expensive.
we drop these makita tools 18v every day holds up good with all the abuse.
Hi Sir i have some questions about engine so when you are free please reply me
I have only killed one Makita tool, a rotohammer that I put through hell and back
I wish manufacturers put metal labels on tools like they used to.
My grandma takes tools apart faster.
Thanks!
You definitely got your moneys worth out of that grinder Andy.
i think he got that moneys worth a long time ago
after 18 years, time to trade up to a younger model for a tighter better feel..like your helpers..
Only Makita 👍
Ppl from first world countries be like
Who the hell is Ben,and why doesn't he feature in these videos?
Ah....Ben is my son. He has been in the odd video but he lives far away in Auckland and only visits a few times a year, usually with the main aim of messing up my workshop! Cheers Andy
Use compressed air and blow out any buildup in the grinder after every use
I thought it was pronounced metarbow
Most probably....use Yorkshire men tend to just say stuff how it reads! Cheers Andy
Ffs man what's with that intro? Kinda tacky imo. Anywho...... I just repair my broken tools and they're good to go for another however many years. Love my makitas. Makita ftw!
you sound like a fruit... the intro is great. piss off
Sounds Like Stuck Brushes Or Bad Switch 😳😮😲👨🏼🔧🧰🧰🧰
Stuck brush this time around.....fix video coming soon :-)
I hope you don’t buy any more brush from that one place you did because if the grinder is 200 dollars that guy will want 300 for two brushes !!!
Definitely not going back there! Nop, got genuine Makita brushes for $13 :-)
whats with the porn intro ?
Thumb down for talking about taking the guard off is OK because you ride motorbikes. This "logic" is complete bullshit and if you think about this for more than three seconds you will agree. Look up grinder accidents. If you are not able to buy a 5 inch grinder for your 5 inch disc you should not get any grinder in the first place.
