Using your Klein 32614 4 - in - 1 Electronics Pocket Screwdriver is easy. First, if you want to access the tip, simply slide the cuff back. You can then use the tip for your electronics work. If you need to reach deeper areas, flip the barrel to the long - side shaft. The rotating cap helps you control the screwdriver precisely, and the cushion - grip handle makes it comfortable to hold. When using, make sure to choose the right tip for the screw you're working on. You have #0 and #00 Phillips tips, as well as 1/8 - Inch and 3/32 - Inch slotted tips. After use, clean the screwdriver with a dry cloth to remove any dust or debris. Store it in a dry place to prevent the steel bits from rusting. Also, avoid using it on surfaces that are too hard or that could damage the tips. With proper use and maintenance, your screwdriver will serve you well for a long time.
