I had exactly the same problem. I replaced it on warranty, and the next one did the same.
The head is held on by spring loaded pivots that are also the electrical contacts. You have to press them down to slid the head off.

1) Remove battery and all visible screws.
2) Remove lens, remove internal screw, pull out white globe holder, and pull out the other metal strip below it.
3) find something thin and narrow enough to fit down the internal grooves, to press in the pivots. On my first try, I had to slide a steak knife down to get the pivot half down, then slide in the spoon handle and remove the knife. Subsequently, I found that just wiggling the spoon would work.

4) Hold the spoons in place, and pull the head off.

5) remove the last screw and look at the electronics. It's a simple setup with an 18v battery, an 18v globe, a switch, an unneeded circuit board. I found it easy to simply bypass/remove the circuit board. Just cut all the wires going into the circuit board, and connect the red to the red, and the black to the black (with extensions to get the disthow to remove case head from makita BML185W flashl - 739c2b5c-e11d-4742-8c99-b067c5a451ac.jpgnet/uploads/images/739c2b5c-e11d-4742-8c99-b067c5a451ac.jpg" alt="739c2b5c-e11d-4742-8c99-b067c5a451ac.jpg" class="h_mi" />However, I got carried away, and will add a parrallel circuit with a 5v regulator and a usb port, turning it into a phone charger as well.

6) reassemble the body, and tighten all the screws. Don't worry about which side the positive pivot or negative pivot should be on. Polarity is unimportant for incandesant globes. (if you modify for LED, you can just swap the pivots to get it right)

7) When you reassemble this. Ensure that you fully assemble the head before reattaching it. If you don't tighten the screw and put the lens on, the metal contact strips can be push aside, and the torch won't work.

8) press down the pivots to slide the head back on.

Be aware that the point of the protection circuit is to protect those EXPENSIVE batteries. You can manage this by simply NOT leaving it plugged in when not is use, and not leaving it on when the lights goes dim. Or you could buy a replacement protection circuit board on ebay.

But especially if you try my phone charger idea, DO NOT LEAVE THE BATTERY PLUGGED IN unless you have protection.

How to replace the lamp in a Mini Maglite

The Mini Maglite is a durable, compact flashlight. If your Mini Maglite stopped working, check or replace its two AA batteries first, and if that doesn't fix it, you'll probably need to replace the lamp. You can order replacement lamps in packs of two online, or you may be able to find them locally in a hardware store.

To replace the lamp in a Mini Maglite:

1. Unscrew the bottom of the flashlight. (Hold the flashlight with the head facing down so that the batteries don't fall out.)
2. Remove the batteries.
3. Unscrew the flashlight head from the barrel.
4. The lamp is mounted into the flashlight on two prongs; gently pull up on the lamp to remove it.
5. Install the new lamp by lining the prongs up with the two holes and slowly inserting it fully.
6. Screw the flashlight head back on.
7. Reinsert the batteries.
8. Screw the base back on.

When you've finished, turn the flashlight on (by turning the lens cover or the head counter-clockwise) to verify that the new lamp works. If the light doesn't come on, take the flashlight apart again and check to make sure the lamp is installed correctly and fully. Since the lamps come in packs of two, if you can't get the first lamp to work, try the second lamp in the pack. If that lamp doesn't work either, check your batteries and make sure the lens cover and head are both screwed on all the way.

How to get the head off the makita Ml140 14.4 volt flashlight?

I'll assume it is the same as my similar 18v makita. There would be spring loaded posts that extend out of the main body into the torch head. these act as both contacts and axles for the rotation.
Remove the lens cover, the reflector, the bulb, and the bulb holder.

There should be a metal strip or wire going down the side to where the posts I mention enter. Shine a light down to see. once everything is out of the way, you can slide a narrow spoon handle (or knife or anything that fits) down the gap to push back the spring loaded posts. There may be channels in the plastic to help with this.

once you've got the post down, pull off the head.

I solved my flickering, by bypassing the circuit board, as all a torch need is a battery, a switch, and a bulb rated to match the battery (check your bulb to be sure)

here is a link to my previous solution, (with photos)

Makita ML 140 torch. Old battery would not hold a charge as it was very old. Torch works well with a new Makita PA14 battery. But the handle gets quite hot and I need to dismantle it to find the problem....

remove the lens, and bulb holder. look down into the cavity, and you will be able to see the spring loaded pivots. Find sonething narrow to push them in with, so that you can remove the head. here is my fix (with photos) for the 18v version

Batteries are stuck in the flashlight. How do I get them out without distroying it?

If they are stuck, they have probably leaked and the flashlight is probably corroded already. But here are two suggestions. Get a heavy piece of string and tie it securely around the flashlight at the lens end. Tape it on with duct tape for good measure. When hung by the string the lens end of the flashlight should point up and the open end should point down. Stand in a place with lots of space and no windows or pets or people around. Swing the string over your head to generate some g's. The batteries may come flying out. Another suggestion is to drill a hole in the battery, put a long screw in it and pull it out. Wear safety goggles. If the second battery is also stuck you will need a long drill and a longer screw. Good luck.

Makita ML902 Flashlight how to open case housing to repair

Makita ML902 - great flashlight. but I wanted to upgrade the lamp to LED, and found that the POLARITY was wrong . so i HAD to open the dern thang. the 'special tool' and 'keep in-house' conspiracy had me 'fuming' ... turns out if one were to mark the EXACT spot that the pivot occurs with a felt pen, by drilling a small (sized) hole on each side, (stop as soon as the bit is thru! the shiney material that you stop at are lamp straps) then pressing 2 stiff objects from both sides, the head pops off ! one more screw is uncovered, making it an even 4 screws holding it all together. When i opened the case up, one wire wasn't even soldered to the switch ! aargh. so - swapped polarity, re-soldered the connections, add a bit of fresh solder, re-assemble, voila! I love the 9 volt cases, upgrading everything to 12v and 16v lithium 18650 cells. these old Makita ensembles are great! saw, drill, angle drill, light...
