In this tutorial, we learn how to use the Bosch PMF 180E multi-purpose saw and sander. First, lock the blade into the saw and then place the screw in using a screwdriver. After this, you will be able to use the saw to cut out what you need to on your type of material. Make sure it's plugged in and you have safety gloves on while you're doing this. To change the blade, wear your gloves and unplug the machine. Remove the bolt to get the blade out and then replace it with the blade that you need. From here, use as you'd like then you are finished.
