Using your Wera 350 PH 2 100mm Phillips screwdriver is easy. Just pick the right screw, place the tip of the screwdriver into the screw head, and turn. For faster work, use the smooth hard zones. When you need more power, grip the soft zones. To find the screwdriver quickly, look for the colour - coding. Remember to keep it away from places where it can roll off. When you're done, clean it with a dry cloth. Store it in a dry place to prevent rust. If you have any issues, check the data sheet or download the product catalog for more details.
