Tools & Materials
Saw chopping into your budget? It's time to face the fix. Whether you are a commercial contractor or a weekend welder, eReplacementParts.com provides the parts, procedures and facts you need to fearlessly fix what fails you.
Due to frequent use, most power tool switches will eventually fail. Once this happens, your chop saw might not turn on at all. Or, it might turn on some of the time; but not every time. Occasionally, a faulty switch will stick in the "on" position. This is a very dangerous problem and should be fixed immediately.
A bad switch will often display many of the same symptoms as a bad power cord and/or faulty motor brushes, so you'll want to perform some simple tests with a multimeter to isolate the exact problem.
