I love Festool and about to add to my collection. I just (almost a year old) started having my CT36 start then stop. At first it would start back again now it just starts and stops. It acts like some kind of protection but I can find nothing that would cause it. Thought it might be plugged up. Started with checking hose, removed hose, removed top and checked filters and all look good. If you have any idea of possable cause please respond.
