Using your Wera 334 slotted flat - head screwdriver is easy. Just align the tip with the slot on the screw and turn. For faster turning, use the smooth hard zones of the screwdriver. When you need more torque, grip the soft zones. Remember to always make sure the tip fits well in the screw head to avoid stripping the screw. As for maintenance, keep the screwdriver clean. You can use a dry cloth to wipe off any dirt or debris after use. Store it in a dry place to prevent rust. And don't forget, if you buy 3 or more Wera tools, you'll get a 10% discount at checkout!
