Question about Makita 5" Disc Sander GV5000

1 Answer

Makita gv5000 5" disc sander won't work

I plugged in my sander and it worked for a few seconds then stopped. I had tripped a breaker. After switching the breaker back on the sander still would not work. I have tried the sander in other outlets in the barn and house since then and it doesn't work. Nothing happens when I plug it in and depress the trigger. I don't have the manual anymore. Does the sander have an internal fuse or something? This sander has had just light use over it's life. Thanks for any advice, Joan F.

There isn't an internal fuse. by the sounds of it you probably have a short, a bad brush, or some arcing.

if you use your sander for fine sanding (100+ grit paper) you have to make sure to clean out the motor housing. Fine sanding dust, like any fine dust, creates alot of heat when aerated and can melt the plastic brush holders or can cause the electricity to arc from one wire to another inside the housing.

my advice is to take the 8 (i think it's 8) screws out of the side of the gun and carefully pull the halves apart. there isnt alot you can mess up inside and just visually inspect the wires for burns or melting on the brush holder.

here's a breakdown if you need it.

if you find something inside that you're not sure of, or if you have any additional info i'll keep checking in on this.

Oscillating drum sander runs a few minutes and stops

This usually occurs if the motor is overheating and the internal circuit breaker is tripping. After it cools down, it self resets. This can be caused by bad bearings or parts dragging the motor down, making it work hard enough to over heat and trip the breaker. If you are running it on an extension cord or circuit that isn't able to provide it with the amps it needs the motor will overheat and trip the breaker also.

Well you did not really say what is wrong?
Are you trying to stop the overheating, or did it get so bogged down from blade heat warpage, that the internal circuit breaker tripped?
If so, then look at the end of the motor, near the cooling vents, and press the little black circuit breaker reset. (not all have them)
Also check that the outlet still works, by plugging something else into it, because you may have tripped the circuit breaker for the outlet, or GFP.

I have a MS1000 Black and Decker Cyclone round sander..looking for replacement sanding disc

Hello, W/D here.
Most sanding disc types are available at the larger box hardware stores. They are (sometimes) generic or exact replacements.
I use the "Gator" brand on my B7D sander, and the discs work just fine.
Best regards, --W/D--
