Using your Wera 334 slotted flat head screwdriver is easy. Just pick the right size for your slotted screw, place the tip in the screw head, and start turning. For high - speed work, use the smooth hard zones. When you need more torque, grip the soft zones. Remember, always make sure the tip fits well in the screw head to avoid slipping and damaging the screw. Keep the screwdriver clean after use. You can wipe it with a dry cloth. Store it in a dry place to prevent rusting. If you use it frequently, check the tip for wear and tear. If it starts to get dull, it might be time to replace it. Enjoy using your Wera screwdriver for all your projects!
