Using the Klein Tools 602 - 4 screwdriver is a breeze. Just select the right screw and place the tip of the screwdriver firmly on it. You can use a wrench on the hex bolster for extra turning power when dealing with tough screws. Hold the cushion - grip handle comfortably and turn it to tighten or loosen the screw. As for maintenance, keep it clean after use. Wipe it with a dry cloth to prevent dirt buildup. Avoid using it in extremely wet conditions to prevent corrosion, even though it's chrome - plated. Store it in a dry place. If you notice any damage to the tip or shank, stop using it to avoid further issues. And always make sure to use it within the limits of its specifications.
