Hi! This is Jon on behalf of Expert Village. In this video clip I will be showing you how to install a blade in our jigsaw. First you need to locate your blade clamping screw. Now if you can't get to it, go ahead and cycle your tool on and off until it gets to a position you can access it. Next you need to unplug your tool. Next you need to take your Allen wrench and loosen up that blade clamping screw. Next if you wiggle the blade it should slide out. Go ahead and insert your new blade, might need to wiggle it in there a little bit and make sure the back edge of the blade fits into the support rollers. After that you need to tighten up your blade clamping screw and then test your jigsaw.
