Most likely, but unless the transformer blew, which is somewhat unlikely, a good repair shop should be able to fix it.

Diodes and sensing cisrcuitry are commonly available parts and not expensive. Transformers are expensive. Even if you get it repaired youll still need an adaptor to convert from the mains 240 to the 120 that the charger wants to see. Get one with a high enough wattage for the charger. Wattage is printed on charger base.

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."

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
