Open the chuck and remove the screw inside the chuck (if fitted) the screw is left hand thread, fit the short end of the largest hex key that will fit into the chuck and tighten the chuck, put the drill into low gear and turn the clutch to the drill position, support the drill on a bench and strike the long end of the hex key with a firm blow (right hand thread) it may be neccessary to strike it more than once
The chuck may have a left hand screw insde and at bottom of chuck, some chucks scew on and the screw holds it in place, may have to put an allen wrench in chuck and hit the wrench with hammer one way or the other to losen it.
look inside the chuck for a screw. it will be a left handed screw.once you get the screw out put the chuck in a vice . you will need to squeeze it very tight. then put the drill in reverse and pull the trigger.if i wont come off you will need to hit the chuck with a hammer while you are holding the trigger.
K what you need to do is remove the chuck retaining screw LH threads and then switch the gear selector to low and the clutch to drill only. Find a bent handle allen wrench about the chuck capacity and lock it in the jaws. put the chuck on a workbench or block of wood and on the long part of the wrench have it at about a 30 degree angle and strike it counter clockwise and that should remove it. you might have to hit it a couple times
Place drill in vice with chuck in vice facing up . Clamp chuck lightly but with enough force to hold firmly. put allen wrench in chuck and lightly tap down to make good fit to allen screw head.Clamp chuck jaws down onto allen wrench lightly to hold wrench steady. Take piece of pipe to end of wrench,10". These chuck screws are tight. Hammer clockwise until screw brakes loose.Open chuck completely and remove screw.Chuck is threaded to spindle shaft . Place allen wrench with long end facing out of tool in chuck and tighten chuck securely. With hammer tap allen wrench sharply counter clockwise ( normal thread.)
open the chuck all the way, insde there may be a screw in the bottom it's lefthand thread turn it clockwise to remove, the chuck is also threaded, right hand thread. close the jaws on the short end of an allen wrench and strike the long end with a hammer to break it free
Are you sure you do not have a tourque adjustment problem. If not I do not believe Makita will want to send you parts,you would have to know what is precisely wrong and by the time you went back and forth you might as well find nearest dealer for repairs and google search Makita.com for service parts near you + zip code to get your drill fixed.
If this is a newer tool it is probably a Torx drive screw usually a T20. The screw is LH thread and after removing it you will need to put some screws back in tool to remove the chuck. First shift the gear selector to the low setting and the clutch to the drill only. Next get a bent handle allen wrench about the capacity of the chuck install the short end of wrench in chuck and tighten. Put the chuck on a block or wood or a workbench to support is and turn the wrench to about a 30 degree angle in the counterclockwise position. The chuck has standard threads so you want to hit the wrench with a hammer to loosen it. This might take a few tries but it will work. Good luck
After removing the screw and inserting the allen wrench shift the drill to the LOW position and turn the clutch to the drill only position. Use an allen wrench about the size of the chuck capacity so that it will not flex when hitting it with a mallet. Sometimes they are stubborn because of the torque but this should work. Put the allen wrench at about a 30deg angle and hit the wrench. I support the chuck on a workbench or a block of wood will do fine. The chuck has standard threads.
