If you mean the chuck jaws seem stuck open, spray around them with some penetrating oil or spray like WD-40, RP-7 or similar and let sit for a couple hours... Then you can tap around the chuck body with a light hammer or spanner etc... just lightly tap... Then if the chuck has an arbor lock to prevcent it from spinning, be sure that is engaged then try to release the chuck jaws. Sounds like they are stuck open through tight friction or rusting on the inside edges (that you dont see). Be careful not to leave them in the fully open position when stored as this is exactly what can happen!

the armature will be burnt out check by viewing where brushers run there should be burning inbetween the copper segments

First open the chuck jaws and remove the LH chuck retaining screw. After that find a bent handle allen wrench about the size of the chuck. Put the shorter end in the chuck and clamp down on it. Put chuck on a block of wood or workbench with the long end at about a 30 degree angle so you can hit it counterclockwise with a hammer. It might take a couple hits but it will come off.

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

You can try the website makitauk.com select parts then choose your tool. Unfortunately it does not break the gearbox down to any detail as it can only be obtained as a complete unit.

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.

The DC18RC are most likely to charged the BL1830 battery, which is the most popular of 18V Makita power tools. It is a Li-ion battery.And the DC18RC battery charger has two volt 110 Volt and 240 Volt. The 240 Volt DC18RC charger can replace model DC18RA & DC18SD because of its improved performance and full compatibility with Makita's NEW 'Star' labelled batteries that communicate between the tool, battery & charger. And, it is a fast charger.It can charge a Makita BL1830 Battery in approx 22 minutes.But, I do not recommend to convert a makita charger model DC18RC at 110 volt to 240 volts.The reason is as below:1. This will void product warranty ! If you follow this mod, you do it on your own risk ! 2. There are several comments that describedsame model # but with different design and components. Please beware that this mod might not work on your chargeror worst, will damage it. Only perform this mod if you know your way around with electronics !

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
