Using the Klein 603 - 7 screwdriver is a breeze. First, identify the type of screw you're working with. The Tip - Ident® feature helps you quickly know if it's the right screwdriver for the job. Then, firmly place the tip into the screw head. The precision - machined tip ensures a good fit, so you can turn the screwdriver with the Cushion - Grip handle. This handle gives you more torque and is comfortable to hold. When using, don't apply excessive force that could damage the tip or the screw. After use, wipe the screwdriver with a dry cloth to keep it clean. Store it in a dry place to prevent corrosion. Since it's not insulated, avoid using it in electrical work where insulation is required. This screwdriver is built to last, but following these simple steps will keep it in great shape for a long time.
