This is my first post and I'm getting ready to send my CT midi in for repair but thought I would see if anyone on here might know my issue. When I use my vacuum on cutting things that create fine dust like MDF, my vacuum shuts down immediately. I replaced my bag sever times, it does not help. I have to hit the power button off then back on again to get it to work. It will cut plywood all day long. It's almost like there is a sensor somewhere that is shutting it down. Any help would be appreciated.
