I have a DCS334 Dewalt cordless Jigsaw. I have used it, but not a whole lot. I've had it for about a year. My blades will not stay in anymore. I install the blade, start the saw, put it up against the wood, and as soon as it touches the wood, it fly's off. There is no holding power for the blade. There are slight scratches on the blade, which tells me something is not grabbing it hard enough. I can actually pull it out by hand if I pull hard enough. Is there a solution to this?
