problem with clutch

you need to replace the brushers

I think that that is just to show that the battery is charging or it may show that the battery is full. You should only charge batteries when completely flat if it is a nicad battery. This is because the battery thinks that any power left is the new empty power level.

Yes they will everyone would charge for inspections unless it was part of an service contract then they may suggest parts may fail soon to get some cash out of it

You can get a 18V replacement Makita battery for your drill. The replacement one is cheaper. Replacement MAKITA BL1830 battery pack 100% compatible with the original BL1830 battery, high quality, wholesale price. http://www.drillbattery.com.au/buybattery.php/makita_BL1830_power+tool+battery.html

Inserting the bit should be the same on all versions of the Makita 3612 router. It does depend on the bit size. Press the shaft lock to keep the shaft from turning. I think the lock is close to the handle on one side of the router when you hold the router with the bit/collet up. For small shaft bits, insert the appropriate collet sleeve into the collet cone. Then insert the bit completely into the sleeve. For larger shaft bits, insert the bit completely into the cone. Use the wrench to tighten the collet nut securely. Unlock the shaft lock. Do not over-tighten or leave the bit loose in the collet cone/sleeve. Over-tightening can break the collet cone. Leaving it loose can result in the bit flying out of the collet cone. Either way, injuries can occur. To remove a bit, loosen the collet nut and then remove the bit (or bit and collet sleeve).

Dead battery?

OK, I do not know which model of radio you have but if it is similar to DMR105, try doing a "factory reset". It is also possible that one of the following has happened: The station you were listening to had a break in transmission. - Try another station. You have lost the radio signal. - Try another station. Your battery has run flat. Change battery/power source.

if you are using a normal 3 jaw chuck on the drill , that is normal when hammering the vibrations loosen of the chuck a method to stop it is to ensure the chuck is tight and keep pulling the drill out of the hole to remove the grit that jams the bit

Yes they all do.

It sounds like the striker (#32) may be installed backwards. If the O-rings are on the wrong end it can't maintain a pressure pocket. Makita HR3000C Rotary Hammer Parts

It is very common for the armature to overheat and melt down. Open it up and inspect the armature, it will be very obvious it is burnt. If it is the case, replace the brushes (#16) and the armature(#14) Makita BHP454 18V LXT Lithium Ion Cordless 1 2 Hammer Driver Drill Parts

Try first to look inside the motor that has much higher priority because the carbon hammerbrushes can be worn (to short)

Are you sure the battery is good? If it is, then maybe the charger went to charger heaven.
