Using over OEM filter!
Running this over my factory 661 filter to keep out the dust from clogging and bypassing the underneath of the HD2 filter, a problem with this saw. It’s a little tight, but no modifications to the saw or cover were needed. I widened the top hole in this foam filter for the cover to clip on easier.
