SOURCE: my chuck is broke , on my 18v makita cordless

Put the chuck key on and strike it with a hammer counter clockwise. the chuck key must be properly seated in the hole. Once the chuck is brokrn free, you can unscrew it my hand. Buy a new chuck an screw it in olace and againm strike the key but no as hard clockwise. It will self tighten more as it is used, Good Luck-Ned-

SOURCE: I have just purchased a Makita 8391DWPETK 18V Cordless Combi Drill - how do i actually put a drill bit in? Do I need to take off the plastic ring?

The large black part of the chuck should turn left and right to extend (close) and retract (open) the three chuck teeth that hold the bit in place. Turn the chuck to open it far enough to get your bit fully in the chuck then turn it closed to hold the bit in. When the teeth make contact turn the chuck a bit further to get it tight enough that the bit won't slip. When you get used to it, sometimes it's easier to hold the chuck lightly and turn it by lightly squeezing the trigger to turn the chuck with the drill motor.
