Using your Klein Tools 85075 screwdriver set is a breeze. First, identify the right screwdriver for the job using the Tip - Ident feature. Just match the tip to the screw head. Hold the screwdriver by the cushion - grip handle for a firm and comfortable grasp, then apply steady pressure while turning to drive or remove the screw. When it comes to maintenance, keep your screwdrivers clean. Wipe them down after each use to prevent dirt and debris from building up. Since they're chrome - plated, avoid using abrasive cleaners that could scratch the surface. Store the set in a dry place to prevent corrosion. Also, don't use the screwdrivers for jobs they're not designed for, like prying or using excessive force. Following these simple steps will keep your screwdriver set in top shape for a long time.
