全く動かない！マキタのディスクグラインダー9533Bを適当に修理する！！

I'm going to fix a "sander" I bought as junk!★ The most common problems with disc grinders are a burnt armature, dead bearings, or worn brushes. If the armature is burnt, the parts are extremely expensive, so a small channel like mine can't fix it. Two sanders are more convenient than one, as they save you the trouble of changing grinding wheels. But a variable-speed sander would be better, though.😅 *No Instagram, Twitter, or other social media. For long-distance communication, please use signal lights or semaphore signals. Or, there's a business-related inquiry section in the channel description.
