What should I check before calling for service if the polisher is not working?

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 'Fitting the Paper Dust Bag' chapter if needed. Note that a service charge will be made if the polisher is examined and found to be in working order, has not been assembled correctly, or has been misused. (Page 6-7)
