Hello, I have older Kapex 120 EB. Blade was increasingly difficult to plunge, now it won't plunge cut. Blade runs normally. Checked for debris that may hinder plunge. Removed blade, started normally but still cannot plunge. Any thoughts? Thanks.
You may have inadvertently done something with the fixtures for making shallow cuts (right side: thin knob and thereabouts). That will lock it if the thin knob has been turned to its extreme.
