I have a Makita #6347d, when I have been using the drill I had some smoke from the battery connection to the drill and the housing of the drill had some smell of smoke. Whats up? Thanks, Bill

If the smoke came from the main housing it sounds like the motor, take it to a service agent. It's a good machine.

Check carbon brushes and ball bearings.

Makita has a 1 year warranty on Lithium Ion Batteries. Contact your local service center ASAP http://www.makita.com/en-us/Modules/Service/ServiceCenters.aspx or call them at 1-800-4-Makita

Makita ML902 - great flashlight. but I wanted to upgrade the lamp to LED, and found that the POLARITY was wrong . so i HAD to open the dern thang. the 'special tool' and 'keep in-house' conspiracy had me 'fuming' ... turns out if one were to mark the EXACT spot that the pivot occurs with a felt pen, by drilling a small (sized) hole on each side, (stop as soon as the bit is thru! the shiney material that you stop at are lamp straps) then pressing 2 stiff objects from both sides, the head pops off ! one more screw is uncovered, making it an even 4 screws holding it all together. When i opened the case up, one wire wasn't even soldered to the switch ! aargh. so - swapped polarity, re-soldered the connections, add a bit of fresh solder, re-assemble, voila! I love the 9 volt cases, upgrading everything to 12v and 16v lithium 18650 cells. these old Makita ensembles are great! saw, drill, angle drill, light...

under the tip section or under my profile in the tip section is the procedure to remove the chuck. Let me know if you need help finding it.

When an AC motor is stalled, very high currents pass through the motor windings and melt the insulation on the windings; the smoke was the result of the motor winding insulation being melted. This causes a reduction in motor torque and premature failure.

You should suggest that your neighbor buy you a new drill and he keep the one that he ruined.

just swap the connection at the motor's ****..

The charger you need is Makita charger DC1801. If you do a search for "DC1801" on ebay you will find heaps of those chargers on there!

The DC1801 charger will charge the 6347D 18v 2Ah Makita NiCad pod-style battery.

Good Luck.

You say will not stay charged? Over what time period? Are you aware Nicad and NiMh rechargeables discharge naturally at 1% per day so where does that leave your power tool after 3 months? Furthermore they only have around 1000 charges in their useful life so you can immediately see how these tools are not for intermittent(ie handyman) use.
