Power Tool Care and Maintenance 101
This article suggests guidelines for power tool care and maintenance. It also describes information tools available at eReplacementParts.com.
I have a Makita 5402NA saw. The brushes are good. It makes a bit of a rumble. Not quite a grinding sound. Under no load it blows the breakers. In the motor housing we have major sparking.
What parts do you recommend we replace? Would lugging the saw cause this issue? Thank you for your help.
