Makita Drills - Page 3 - Recent Questions, Troubleshooting & Support

Hi there the solution for how to mod a DC18RA charger can be found here. The "how to" comes with pictures and descriptions and it should be easy to follow, and best of all it works :)

What has happened is the hex part of the bit has twisted slightly making it hard to remove. What I would do if you are comfortable with partial disassembly is remove the quick release mechanish. There is a split ring that comes off first and then a washer and spring, next remove the outer collar and SMALL steel ball from side of chuck. I take a pick (dental tool) and push up or try and twist the stuck bit. Sometimes it takes while but usually this works. Let me know if I can try and help further.

you can buy the part exploded view says part 6 look simple ..?.the way in is undo the top casing leave the motor section in place if possible Makita 3700B Trimmer Parts

The brushes are probably wearing out. They can also smoke if they get dirt or something on them. You can take the drill apart and replace the brushes, but if they are just burned some, take some fine sand paper or emery cloth and polish the armature where they run and clean the brushes and reinstall.

Brobaly not making proper contact when you plug it in

On the Makita 18-V DC18RA charger, the flashing red light means that the battery is not at the correct temperature for safe charging. If the battery is hot (from use or being in direct sunlight), charging will begin when the battery cools down. If the battery is cold, then charging will start when the battery warms up. (Note: the cold battery could have moisture condensation issues. This could delay the start of the charging cycle.) Home Depot has the manual for this charger here: https://images.homedepot-static.com/catalog/pdfimages/35/35393127-7c0b-4668-8609-9104ae7cc187.pdf . I suspect that Makita uses the same "code" on all of their chargers. I hope this helps. Cindy Wells

You can try to recharge batteries and see if they work by placing them in tool. If you are using Ni cad batteries and charger, you would better served by going lithium ion batteries.

I’m not sure if you can buy a new c/board .
The charger tests the battery before charging & if it picks up a fault it won’t charge the battery. At our repair shop we just replace the whole battery ( under makita warranty if it’s under two years old / depending on what warranty your country has )

Having same issue with different model charger...skil....
Might be a fuse or something inside charger blown maybe, as I'm reading it could be somewhere online. Not positive on this.

MOST mAKITA POWER TOOLS HAVE A 3 YEAR WARRANTY. THEY MAY REPAIR OR REPLACE YOURS AT NO CHARGE. DON'T WORRY ABOUT RECEIPT UNTILL YOU CHECK. DATE OF PRODUCTION ON TOOL MAY BE ENOUGH PROOF.

Do not keep her on cold place. sorry but you have to buy new one again :/ take a look on amazon or something: Amazon com Makita 18 battery

Yes, there should be a couple of tiny holes in the brush holders you can push tiny Allen wrenches in to hold brushes back against springs to clear armature to assemble.

go to Makitatool.com and type in your model number and you should be able to download a schematic, if you have a problem let me know and I will go another route for you.

The serial number is on the main label. Unfortunately they have a habit of wearing off.

Squirt a little release oil(WD40 type) on the other part of the jaws and the inner of the chuck.then push the forward /reverse switch to the Arrow pointing forward(toward the chuck) then holding the chuck with the drill in No1 speed gentle pull the trigger until the jaws release and move all the way to fully closed.After this the drill should work properly.

replace battery or buy a new tool

Most likely replacing that Resistor is not the only problem, do you know how to replace surface mount components? I can look on a know good unit and see if there is a value or measure it. Surface mount components are not sold like regular electronic parts were.

you can try going to either makitausa.com or ereplacementparts.com for a parts diagram. Let me know if you need more assistance.
