[@jernejloknar8011]

Most of modern drills have this problem, the switch itself does not always instantly engage if gears are not synchronized, which is more common if gearbox is shorter than usual. There is now most of time a extra spring in the selector that helps with such gear change, you can always move the selector but gear will only engage when gears finally succesfuly synchronize / move.

Did you buy from Pro dealer, or home depot. The pro Dealers, sell metal gears makita tools. But home depot and many big companies have gotten cheap because they want more profit

[@muhammadalhasani2841]

I like to repair electrical and electronic faults, and I appreciate your experience

[@vasiltop]

Hello, I bought a new ddf 486 and it seems to me that it heats up from the back without using it, I just press the trigger, is this normal, is it without brushes? Should I be worried or not? Thank you.

[@jonathan-pf9fv]

Hey thanks so much for the explanation!

[@jonathanpotts5466]

Thanks for the info and advice! This has been driving me crazy whilst using my DHP484

[@deandohertygreaser]

Stay tuned. I may have actulay fixed the problem altogether. Must test it out first before posting video and calling makita out on why they haven't fixed it yet.

[@jonathanpotts5466]

Great! I look forward to seeing that @@deandohertygreaser

Finally have an explanation for my Makita drill that has done this from new in the fast setting. It drives me nuts. I’ll try that solution. Thanks.

[@waynoswaynos]

Nice one,thank you friend. With your advice I solved the same problem with a smaller Makita brushless drill, the DDF485.

[@YagrumBagarn]

My hand slipped from my Bosch 18-60c gear from 1 to 2 speed I think when I was drilling some wood and it sounded just like this I tought I broke it but it still runs fine thank you for the explanation🤠👍

[@joshclayg]

My 486 will show this problem and after a few seconds of high torque drilling, say step cutting slowly in slow speed, is this the same issue? Drives me insane! Mine seems to be the opposite, happens in slow speed high torque drilling, at the beginning and whilst drilling.

[@nickmurphy6515]

I’ve had this same drill for a couple of weeks now and noticed it was doing this today but mine does it without changing the speed it just does it randomly, should I send it back?

[@kevinansell9341]

Just brought one of these Puppies today, Thanks so much for this info which will come in handy one day no doubt..

[@marceloccraul]

Does the Makika DHP489 also have this defect?

[@eaglebaldonetough4074]

High Sir got the same with brushless motor broke doown how can I change it and where to buy. It please it smells burnt

[@maximilianolucuix8197]

Thenks so much!!

[@boby4509]

I love this drill, but I have a big problem with it. The break make a crazy noise when trying to stop. Do you know any fix for that. Thanks in advance!

[@enemyofthestatewearein7945]

I've seen a very similar problem to this with my old Elu and some Dewalts jumping out of gear. Those have a wire clip on the gear selector that gets sloppy with heavy use, then it's hard to engage in either speed. I used to just leave all the drills in one speed or the other and swap drills if I needed to change gear.

[@stevenwilliams6310]

My dhp486 is stuck on hammer drill.. how do I fix that?

[@maximilianolucuix8197]

And the problem with the brake? Is realy a problem? Or just is normal the noise

[@Amber57499]

Good thing I couldn't sleep and googled this. I was about to buy a new one thinking mine is broken.

[@chucknorris2952]

Have a ddf484 with brushless motor. It runs occationally, but only for a second, then stop. Is it the motor/stator?

[@deandohertygreaser]

Might be your brushes.

[@GrosserAndrew5000]

I have thisbexact problem, loud noise. Hope to have this help me out, thabks for the video!

[@user-yk8oq3ov6i]

My DHP489 makes a loud mechanical noise, like a gear jumping inside the machine, this happens when the drill is using force. for example if I drill a hole, when the drill bit hits the hard part the machine gives a loud bang and continues its work as if it were normal. do you think this is normal?

[@deandohertygreaser]

Dose not sound normal

[@tunebg]

I have the exact same problem with a lot of the brushed combi drills

[@stefantrethan]

I have not noticed this issue, but on my DDF481 the adjustable torque settings are ridiculously low. Even the highest setting is just a fraction of the torque this drill can put out. So I always have to use it in drill mode, where it will snap your arms clean off at the elbow when it grabs. I've already broken one side handle because of this, but at least they sent me a spare. I don't know if my drill is faulty, or if all are like this, but especially on such powerful drills a functioning torque limiter would be useful.

[@The_fappening]

Torque settings should almost be a linear increasement from 0% to 70% to drill

[@stefantrethan]

@@The_fappening Thanks, then mine is definitely faulty, it's nowhere near 70%.

[@Elektrotechniker]

Usually good drills have a kickback protection…

[@stefantrethan]

@@Elektrotechniker It would be fine if the clutch worked properly. They have a right angle drill and earth auger out now, which makes a whole lot more sense than packing 100Nm+ in a standard pistol grip design anyway, making the DDF481 mostly obsolete.

[@hotcoffee383]

That’s the best explanation I’ve watched or heard. If you moved a few thousand miles to my neighborhood, you’d find me in your shop/garage bending your ear about a few tech tool problems

[@Holymolygod99]

My XPH14Z has the same issue , but works fine

[@BillyRillkratz]

Cheers Mate!

[@CYMotorsport]

should have opened it to confirm and also show the mechanism. and show people it's really not difficult to repair. just be careful with the reverse hammer. makita has a few great 3d printed ones on thingiverse - i've broken 2 now but they fit perfect. just get them back in place very carefully before locking everything back in

[@MsMad555]

Tam jest jeszcze taki problem że pierścień przesuwający bieżnie trybów jest z tworzywa sztucznego i jest elastyczny gdy by był drut to szybciej by wskakiwalo na właściwe miejsce!

[@STV-H4H]

I have an American marketed version of what I believe is this drill. (Actually I have 2, but because they’re identical, I can’t remember which one does this, but I suspect both are guilty) I took one for warranty repair and they couldn’t replicate the problem. So I’ve been wondering for a couple years how I’ll get it fixed. Most of my work is done using my lighter duty drills (all 18v makita) and impacts which why I never returned to the problem. Because the troublesome drill is only used when I have hard wood or concrete to be worked on. The plastic chuck units are never trouble. It’s funny, the dealer that was supposed to do my repair laughs at me for having the Home Depot marketed Makitas, yet the POS they push (the ones with metal chucks) are my problem children. Hoping this video might inform me how to DIY, since the experts aren’t seemingly too concerned. Rats. I watched the rest of the video and saw there is no breakdown of the guts.

[@brianwood5220]

I get the same issue with my similar sized Bosch Cordless Drill.

[@perks25167210]

My 481's on the bench now, stripped to regrease after tonnes of dusty work and I've fucked something. Can't switch to hammer and that and she's rougher than a lizards chin running. I know I've done something daft. Wish me luck 😂

[@RyanH87]

My one does it bad in gear 1 and 2. It's almost impossible to drill a medium sized hole. I use gear 1 mostly and it's absolutely useless. This solution switching gears has no effect for me

[@chrisobrien5264]

I much preferred the previous model with the separate torque/ hammer, screw gun selector. Bought this model after my previous one was whipped off a job. The new model constantly slips into hammer mode

[@deandohertygreaser]

Yea, there js a few problems with this model I don't like.

[@x4px]

​@@deandohertygreaserhi dean, love the videos and was trying to use this video to fix my exact model, the issue is the drill does nothing when the trigger is depressed (this has been changed for new) apart from a slight crackling noise coming from behind the top label of drill details area, sounds like something is frying inside? any help will be greatly appreciated, thanks jarrad

[@Wavelover33]

Yeah me too. The thing drives me crazy plus it is slipping. The one thing Makita can’t make is drills that last. Drives me crazy

[@peterthebricky]

mine stays slightly in percussion mode when it’s in drill only mode not a major problem but annoying

[@kizzjd9578]

Both mine do that

[@gordonyeomans6220]

just sent my new DHP486 back for warranty repair for this problem,I also have difficulty setting in either hammer or drill, I have to rotate selector full turn both ways to get in correct mode

[@rudolfzaris675]

I will never buy a 18V drill with hammer function. Just a regular one. Thanks for shareing.

[@user2C47]

The gearboxes of this model and the non-hammering version appear to be interchangable, which means the actual gear drive will likely be the same.

[@solehhadi7714]

simple problem 😅 permasalahan hanya karena di dalam gearbox kurang pelumas , jadi perpindahan gigi terhambat . Alangkah baiknya jika peralatan yg mengandung roda gigi , ditambahkan pelumas lagi . Karena tidak menjamin bahwa dari pabrik pelumasnya cukup . Kan pabrik juga berharap jika peralatan itu rusak , kita harus beli lagi

[@nikolai420]

Was running into that sound whilst drilling hole ice fishing

[@joaquinchan9936]

I think the new metabo hpt/hikoki hammer drill does that same thing.

[@LeadingInnovations]

Very nice video! Where is this accent from?

[@shifty277]

The company I believe is Donegal fixings. There's the clue

[@highgatehandyman6479]

Same drill I think. But mine slips in 1st gear. We'll annoyed

[@fordford9133]

I see man making gear parts for one He all the gear for making then

[@Cacheola]

My 11yr old 1/2" makita hammer drill does this as well. You think they'd have fixed it by now lol

[@atnamesarelame]

Has your drill worked fine with no issues all these years even with this slipping?

[@Cacheola]

@@atnamesarelame yes it has. I'd been meaning to take it apart and see if it was a simple part replacement, but after watching this, I'll just leave it. It only happens once in a while. I've had a few Makita drills... 7.2 14.4 and 18v, every single one has had an issue with the chuck as well. I do like my Makitas though

[@atnamesarelame]

@@Cacheola oh ok. Thanks. As long as it remains reliable that's all that matters

[@markmawson1]

Looks like they have done away with the floating battery mounting

[@robertrada4783]

They only do that on impact wrenches and some sds plus/max

[@stauker.1960]

​@@robertrada4783 isn't there plastic bushings in there anyways? That's already more than DeWalt and Milwaukee, and probably Hilti too

[@yohanathandowns9057]

​@stauker .1 my Milwaukee brushed multi tool has rubber grommets to keep the battery in tight. All my other tools have the slot for it but it isn't there

[@jaywelker5566]

nope. Rubber bumper pins are still standard on most tools this drill and the drill before it has them. Some tools like recipros and SDS hammers get extra. Only impact wrenches (mid/high torque) get the extra dampener at the base of the handle.

[@deandohertygreaser]

No mark, they dont use the floating mount on the drills or impacters. Only on tools that get a lot of vibrations like nut guns, multi tools, sds drills ect.

[@TimmyTheSnail]

481 does the exact same thing after a lot of use

[@dimitri4383]

never change gears under load I guess

[@Radovakos]

I have fixed the slipping gear problem

[@Basnak]

Can you tell how you have solved it

[@Radovakos]

@@Basnak you gotta open the gearbox , and change two pins that are holded in a plastic that changes the gears ⚙️, those two pins sit one up and one down, and change them to the side

[@atnamesarelame]

​@@Radovakoscan you make a video on that?

[@Radovakos]

@@atnamesarelame ok

[@FlybyLV]

@@Radovakos waiting for 5 months mate for the video....

[@1970Mazot]

I solved a similar problem. DF482 and DF332 models have the same gearbox. When the 1st gear in the box is shifted, the large wheel with 3 arrows on it enters the hollow metal on the washer between the two wheel chambers. Sometimes the insertion part does not fit and this creates an ugly sound (this is exactly the problem). To fix it, it is necessary to widen the hollow metal teeth on which it sits.

[@riba2233]

yeah I have seen a few complaints about this model, 40v def looks like a more solid option.

[@UltimateToolReviews]

I don't need any more reasons to upgrade to the XGT, lol.
