BLADE CHANGING CHANGING BLADE ON BOACH JIG SAW TYPE 0 608 554 008 THANK YOU
What's the model number of that saw?
If it's one of the old ones, a 1581 VS or some such, you need a long thin flat-head screw driver that fits through the hole in the top of the handle and reaches down far enough to unscrew (loosen it) the set screw that holds the blade locked in place. Then you twist the blade 90 degrees (perpendicular to the direction of cut), and pull it out. Reverse process for installation, making sure before you tighten the blade it rides in the groove on the guide bearing below.
If that doesn't seem like it's the correct sequence for your saw I apologize.
The Bosch website won't accept any 10 digit tool product numbers due to some glitch in the system, and they made so many variations on that saw it'd make your head spin.
That's the other way some of them loosen up, actually, is by pulliing up the plastic head at the top of the handle and unscrewing it a few turns to loosen the blade.,, Vice versa for install..
