BUFFALO Grinders - Recent Questions, Troubleshooting & Support

That entire older Buffalo line of grinders: N-10CB, B-8CB, B-6CB, bgbr-6cb all use the same push pull switch. Most of those grinders were dual-voltage with a starter capacitor and there are 6 wires connected to a 4 contact switch. The "Jet BGS8-076" grinder switch that is used by the older Buffalo's, Galaxy, Duracraft and TestRite grinders is no longer available. The good news is that there is a replacement switch from another manufacturer: "3030-9001 push pull switch for RDX grinders" from Wholesale Tool is a direct replacement. It has the same 4-screw contacts on the back and the same push-pull diamond pattern front plate.

An adjustable centrifugal start relay and or capacitor problem. Nonsensical Bench Grinder Wiring Diagram Diagrams Switch Buffalo 6cb 6510...

A coil is just that a coil and unless it has diodes it doesnt matter how you put it on. let me know (diodes are those things that are usually black with a silver stripe -cylindrical in shape)

The neutral line should never be switched--only the hot wire (black). If there are only two wires that went to the switch, you should be able to tie them together and the motor will run when plugged in. The switch should be a common SPST type either toggle or rocker to fit. Hope this helps!

I had the same problem with a Northern Tools bench grinder. These are made in China and parts are hard to come by. I had enough room after removing the old broken on/off switch to install a single pole 15 amp light switch like you use in your home. I simply installed it horizontally and then put the switch cover on. It works perfectly. If you do not have enough room then look for any 15 amp or larger switch that will fit in the housing. Any on/off switch will work. You could even mount the switch on the bench in a switch housing and run the wires from the grinder to the switch and back if need be. Just be safe and make sure there are no exposed wires. As a last resort you could remove the switch connect the wires, eliminating the switch and use a plug in wall switch such as this.

depends on condition and what comes with it. generally starts at $500 in good shape and up to 850 if excellent with many extras (chucks, rests, knurling attach, faceplates, etc) Also, check for accuracy...

Yes all the tool places say discontinued. Yes, bypass it, but make sure you don't overwork the grinder. https://www.google.com/search?q=2610904741 ..

Out of warranty ... time for a replacement machine.I would choose a different make. Assuming the batery is not the fault.

DIRTY CONTACTS POSSIBLY

Size for size and component value identical on replacement. Fit the correct part.

Considering how potentially dangerous grinding machines and wheels are and how much safety legislation exists about their maintenance, adjustment and use, a great deal of printed matter exists about these things and the wide range and selection of wheel material. You should have no bother finding useful information, fortunately bench grinders are extremely similar to each other... https://images.homedepot-static.com/catalog/pdfimages/b6/b64b39fb-6d42-4fec-a274-76bbd950e6d8.pdf

Mmmm... that's a little more complicated. If you have a continuity / resistance meter, we can noodle it out, though. First, are the two white wires the ONLY wires coming from the motor? I suspect they are - that's not in conformance with any accepted color code, but it'll work. For the rest of this, I'll assume that the two white wires are the only ones from the motor. You'll need to meter the switch itself, with no wires connected to it. In the OFF position, you shouldn't find continuity between any of the four switch contacts. In the ON position, you should find continuity between two pairs of contacts. The black wire from the power cord should go to ONE of the two switch contacts in a pair that have continuity with the switch turned ON. One (either) of the white wires from the motor should go to the other switch contact IN THAT PAIR. That leaves you with one more pair that has continuity with the switch turned ON. The white wire from the power cord goes to one of those, and the second white wire from the motor goes to the other one. When you have it all wired up, plug it in & turn it on. If it's not right, it should immediately pop your circuit breaker. If it IS right, it should run fine. If it pops your circuit breaker, open it back up and swap one wire from the power cord and one wire from the motor.

One turn.

Find a Single Pole Single Throw (spst) toggle switch at the local hardware store rated for the load of the grinder. Wire the switch in place and viola you are done! Machines are stupid;they can tell the difference between an oem part and a replacement.

You can get a replacement toggle switch at any hardware store look in the electrical department.

If you can't find the direct replacement check with Grainger or other industrial supply house ... https://www.grainger.com/category/push-pull-switches/automotive-electrical-and-lighting/fleet-and-vehicle-maintenance/ecatalog/N-15m5?okey=push-pull+switches&mkey=Push%2FPull+Switches+&refineSearchString=push-pull+switches&NLSCM=5&EndecaKeyword=push-pull+switches&searchRedirect=push-pull+switches&sst=subset&suggestConfigId=6&nls_boost_words=noContent
