I have a Delta contractor TS thats about 15 years old or so. I have been having a slight problem with the saw turning on and I cant tell if its the switch or some other electrical issue.
Here is what happens, every now and then I will go to turn the saw on and the saw will either power up for just a quick second then kill or it wont start at all. I am not flipping a breaker in my panel when that happens so I am thinking the issue is in the saw somewhere. When this happens I flip the switch on and off and nothing happens. I then unplug the saw, plug it back in, push the button on the motor (even though I don’t know what it does, just seemed to me to be some kind of reset button, its red) and turn the saw on. It will usually start after I do that but sometimes it doesn’t and I repeat the steps until it starts.
This does not happen very often so I just kind of ignored it. However I have noticed that the problem tends to only happen when the saw is unplugged and plugged back in or after moving the saw around in the shop.
The switch on the saw is NOT the original delta switch. I bought the saw used and the previous owner replaced the switch which had gone out with a single pole switch. Looking at his work it all appears to be wired just fine.
Also if someone could explain to me what that red button on the motor is and if it is a reset button like I assume what would be causing the motor to be doing this?
The problem only happens when its first turned on. I have never had the motor kill during use and I don’t see, feel or hear any problems when using the saw.
I am just stumped as to where to start looking. I am thinking it could be one of a few things either a loose wire, bad connection somewhere or not enough power being supplied to the motor. Worse case its a problem with something in the motor itself, its wired for 110 and I do use an extension cord with the correct gauge wire.
I hope I have explained enough for someone to hopefully help me with this. I am not to smart when it comes to motors and how they work.
