Hi, I was given a PS 300 jigsaw a while back and when I came to use it for the first time I noticed that after inserting the blade it doesn’t sit straight. It looks as if the when releasing the locking lever it pulls the blade across to far so it’s not sitting straight through the guides by quite a way out. Is there an adjustment I’m missing to straighten it up? It’s not that the foot plate is out as the blade is visibly off down the jigsaw body itself. Releasing the locking lever slowly it hits the blade, gets to a point where it’s sitting straight then pulls it over another few mm. is there something simple I’m missing?
