on a grinder the nut that holds the wheel on has left handed threads.....that means it has to be turned in the opposite direction than conventional nuts do..there should be a button on the casing to hold in..this keeps the grinding wheel from turning wheel being removed....remember to unplug first..thanks and have a great day

Hi J,

Hopefully you just wore out the brushes. Replacement kits are available for a few bucks and the fix is pretty easy.

On the darker side, If it overheated enough that it burned the windings (insulation melts, shorts, badness), there isn't much you can do unless it's still under warranty.

You won't know until you get it apart. You'll know which it is at a glance.

Unplug it and dismantle the base of the grip where the cord is attached.

The brushes are small spring loaded graphite blocks that transfer electricity to what looks like a cylinder around the central drive shaft that has a lot of vertical copper strips on it. They are normally housed inside small copper tubes opposite each other.

If those tubes are empty but for the spring, it's brushes.

If the insides are full of ashy residue, it's not the brushes

Best regards and I hope it it's the brushes

Mike

My makita angle grinder(9527NB) the on switch only works when it wants to. Turn it on dont work, bang it and it might work. Any suggestions


This is definitly a bad switch. You can contact Grainger or MSCDirect, and give them the model number and the make/ They should be able to send you out a new switch. These are pretty basic circuits and only take about 20min to replace.

How do you remove and release the quick grinder pad?


There is a button at the front of the grinder usually black or red, depress it lightly and rotate the wheel (unplug grinder please) wait until you feel it fall into spot, depress tightly and hold then turn wheel and unscrew to replace pad. Reverse to reassemble.Good Luck....

Dear Sir, We have few Metabo grinder I have some doubt about Dead man switch can you explain me what is the function of dead man switch. Regards Nitin


Hello, a dead man switch functions in this manner. As long as you hold the switch down the grinder functions, and as you know when you release it the grinder stops. This is a good safety feature in that if you drop the grinder of lose control of it, if the grinder stays running it could cause a lot of damage to material or your body. The switch can seem to be a pain when having to hold it down all the time, but it is a safety feature that can actually save your life in the case of you losing control of the unit.

Bosch angle grinder stopped cold when tapped lightly


Yes, if you have taken the handle halves apart (unplug tool first) check with your meter thru the blades on the cord to the switch contacts and then lock the switch in the on position and check across the switch and then remove the brush caps and brushes and check thru to the brush holders, if at any time you lose continuity then that would be your problem. Let me know if I can help further.
