  If your Makita Vacuum Cleaner motor doesn't start, it could be due to a blown fuse in the mains socket; connect a mains fuse. Another reason could be that the overload protection switch has tripped; in that case, switch off the vacuum cleaner and allow it to cool for about 5 minutes. If it still doesn't start, contact the service department. Finally, the self-acting carbon brush might be worn, in which case you should have the carbon brushes changed by Service.
