I went to the trouble shooting page for my polisher and checked possibilities. The possibilities were listed by item most likely to fail. I chose the first three possibilities and ordered the parts since I didn\'t know what the problem was. I replaced the trigger switch first and that solved the problem. The remaining parts ordered wi ll be held in reserve for future repairs.
