What should I check before calling for service on the F3860-1-011?

First, check that there is a working electricity supply to the polisher by testing with another appliance. Second, check whether the dust bag is full and refer to the chapter on fitting the paper dust bag if needed. A service charge will be made if the polisher is examined and found to be in working order, not assembled correctly, or has been misused. (Page 6–7)
