Makita 18 volt BGA452Z Grinder Cut off wheel: Has anyone else had issues with this machine ?
1571728
I use mine frequently, I keep either a cut off wheel or diamond blade in it. It does like a fresh battery but I use which every battery is handy, my batteries are 3 and 6 years old. They seem to last a while. The leds begin to light up before it shuts off if I am driving it too hard warning me to apply less pressure. I keep the 120volt grinder on the truck also though for heavier jobs. I would agree it is one of the few 18volt tools that does not completely replace the need for a 120volt tool but I find it extremely useful and bought one for my father and brother who are also contractors for Christmas last year. With 33years of trade experience I will buy a new if this one ever fails. As far as saftey, Makita engineers must of found some problem with letting it run the battery to zero, none of my other tools seem to have this type of cut-out.

Hi mark. Without knowing " how fast is enough" for what you are doing, I would hazard a guess that there is a problem with your grinder. They should have a max rotation of about 10,000 rpm max.

I've had mine for several months and it's working fine. I do clean it out on a weekly basis by rinsing out both hoppers and the removable blade and blowing out the body of the grinder. If it only worked 10 times, it might be defective. Send it back.

I had a similar issue with mine. I noticed that the cradle above the grinding element was not locking into place. There was a dense layer of packed, finely ground coffee that seemed to be inhibiting the cradle from locking. Once I cleaned that out (with a somewhat sharp wooden chopstick), the grinder started working.

Bernard, I also want to remind you that we offer a lifetime warranty so that in the rare case the grinder fails we will ship you a placement unit. And just like the other guys mentioned, like any tool it should be cleaned when needed.

That's what we use, never had this problem. Does the grinder appear to be turning freely and do the batteries appear to be strong?

Yes. I am trying to locate someway of having it replaced by Dewalt. Pain in the arse! It happens when you let go of the trigger suddenly and the brake kicks in and opens the chuck. Bad design.

I just got mine and I'm wondering if I should return, my drive shaft appears slightly bent and when I grind with nothing inside it scrapes ceramic on ceramic at one section of the rotation. :(

Mine did the same thing. It made a grinding sound and would never go back into the start position. I called support...everything, they couldn't/wouldn't help. They were going to give me a small credit to buy another one. I declined since this one had broke within a year. I decided that since it was broke anyway and I couldn't use it, that before it made 'in position' beeps to start, I would manually move the cutter all the way over into the start position(while it was making the grinding noise). There is a trigger in the start position that tells the machine that it is ready to start. I did this SEVERAL times with no success. Machine was useless. Then I tried again and I must have had the right timing. It has worked ever since...no grinding noise. It's all about timing and I don't guarrantee my fix will work for you. I figured the machine was a waste anyway, so I might as well try it (even though in my mind I figured I would break the gears by doing this. Didn't matter...it didn't work). If you are ready to write it off or throw it out the window...give it a try.

I run a 1/2 inch impact pretty regularly. It doesn't cycle that much. It has a very hard time with a cut off tool or angle grinder.

There are constant problems with everything on this machine. Mine needs some kind of maintenance work everyday. The drive belt jumps off, blade guides get loose, upper blade guide doesn't work when sawdust gets in it., wheels are difficult to bring into alignment and works best with Timberwolf Blades. No more than 4 tpi if you can find them. Try Suffolk Tools.

I haven't had any problems however the first two I had quit working after only one time. This is my 3rd one since March and up to this point & time is working, the grinder produces consistent and smooth grind. No complaints at this time however if #3 doesn't work out, I will not get another one. This one is perfect, right now.

Thank you so much for your reply. I finally ended taking the machine in for repair. Apparently a part needs to be replaced.But I will keep in mind the MX850 in the future.

When you say "grinding halt" do you mean that the blades literally stop instantly or do you mean that turning it to Med or Low is like hitting the off switch and the blades just slow down until they stop? Because if it is like hitting the off switch, then it just means you need a new switch. If the first hing is happening then you have some other major problem.

The comment about the plastic transmission cover is quite true. I have replaced numerous plastic covers with the heavy duty aluminum cover. None of the users said the grinder was the fault for the failure. Long run times over 20 minutes and repeated use of the dough hook was the culprit over 90% of the time.

There are several issues with this saw that need to be corrected. I am constantly squaring the fence among other things. If it's not too late, return the saw for a Bosch. If it's past the 30 days call Makita, they will claim that this is the first time that they have heard this complaint in an attempt to make you believe it's your fault. Don't buy it. Do a Google search on complaints for this saw and you will think very differently about the quality of this particular Makita product. I own over 25 Makita tools which are all good except for this one. I would have got a Bosch but Makita gave me the saw free of charge.

No, I've never had a problem with this machine (so far) Maybe it is just your machine and you should ask the mfg. to replace it? I'm sorry to hear that you are having problems.
