Tripping breaker. K700s

 

Yesterday I did a blade change from my groove cutter to a saw blade. While the groove cutter was off I vacuumed out the cabinet. When I put the new blade and riving knife back on and closed the cabinet I had no power. Tried the main power button and the one at the end of the slide. Nothing, no clicking etc. I flipped the breaker and all was good. Today I did a blade change, same problem! Has anybody else run into this problem??

Hi Paul,

I don¡¯t see how a blade change can result in tripping the breaker in the main electrical panel. May be just a coincidence. To start, I would measure the current to determine if you have a short in machine or the breaker is going bad.

Hi Paul,

Perhaps the microswitch for the blade cover has dust in it and doesn¡¯t always reset when the cover is closed?

I am leaning towards that. It is strange that if I flip the breaker it resets the saw??

Hi Paul,

If the microswitch was causing the no start, the power cycle should not reset the switch from open to close. So what I recommended earlier was based upon the likelihood of the failure mode. An otherwise good breaker in past, should not suddenly start tripping unless it has gone bad or the current has increased past it¡¯s threshold.

If you can eliminate this as a possibility then we can dig deeper.

This could be a stupid idea, but if this started happening just after he vacuumed the inside of the cabinet, my first thought would be a somewhat loose connection that could be causing an arc.? Like a plug that worked itself loose.
