Hiya my polisher has decided it doesnt want to work today. Was fine last time i used it but did notice it was cutting out thinking it might be a loose connection or something? The carbon brushes were recently changed and havent worn so cant see that being the problem. Has anyone had any loose connections on theres thats worth checking. I have owned it for quite a while so out of warrenty. When i switch it on i can hear power around the back near the speed control setting.
