Makita 18 Volt Cordless Hammer Drill Kit 8444dwde - Answered Questions & Fixed issues

It sounds like that the chuck jaws are out of alignment. You will need to get a new chuck.

go to makitausa.com and you can download a parts schematic. You will need your model number for this. Let me know if you need more assistance and if you do I need the model number also.

the switch or motor is wired incorrectly. These parts are polarity sensitive. The smoking I would assume is from the old switch and now the rotation is reversed. Let me know if you need more assistance.

Hi there, the chuck will screw onto the spindle of the drill but there is also a screw to undo. Open the chuch out fully then look down the centre of the chuck and you will find a philips head. The thread on the screw is opposite to the normail way so instead of undoing to the left, undo to the right.there should be threadlock on the screw so may be abit tough for the first turn. Once removed a strong pair of grips and a good tug should then remove the old chuck, some are more orqard than others to remove so just keep trying.

There is suppose to be a flat head Left hand thread chuck screw in there. It may have fallen out. You will not be able to put the jaws back into the chuck. You will have to replace the chuck with a new one. If you make sure that the chuck screw is not there you can remove the chuck with a couple of steps. Make sure the drill is in it's lowest gear. Use a strap wrench or some large vise grips on the chuck. If there is still one jaw in the chuck make sure it is all the way open and locking the collar to the chuck. The chuck will come off in the regular lefty loosey configuration. It may be stubborn. If this is the case, You may have to cut the collar off the chuck and use a pipe wrench. Or bring it to a professional to get it changed out.

I don't really know how a chuck works. I use them often on a drill press, cordless drills, etc. My grandfather always said to "check the simple things first." Could something have gotten in the way like saw dust, dirt.....? ? I might suggest trying using compressed air and blow it out? You can buy a can of compressed air at office depot.

There are no serviceable parts in this charger, it is a replacement item

Lithium Polimer batteries are 3.7volts per cell. They need specialist charging and protection. Maybe not the best choice ...

Yes, because the voltage and amperage input to the charger is constant, so the board management dumps excess charge once the battery is fully charged. The battery cools, but the charger warms up. Mine does the same. It is a 15 minute charger, so the current is high.

Hi. Just to clarify, it is a rotary hammer drill, not an impact drill? In most cases those machines put out 3 joules of energy on the back of the drill bit. If it was a cheap bit, the hammer action "mushrooms" the end of the bit making it difficult to remove. You could try to force it out using a bench vise, but you could damage the chuck.

I think this radio uses two different sets of batteries. There is the smaller batteries that store preset radio stations and a larger battery pack to power the actual radio. If your partner had other Makita cordless tools some of those batteries will fit and there will be a charger for them. I've put a link to a website for a users manual. (try looking at page 3. The larger battery will be a black block which is the same type used for the cordless tools. The squarer battery pack style should slide upwards towards the handle and the rounder shape battery packs should just pull out. Talk to a good builder or a Trade tool supplier and they may be able to help or order you the power cables you need. If not contact Makita directly and they will be able to help you. https://www.manualslib.com/manual/1339075/Makita-Xrm04.html?page=3#manual

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.
