Using this Klein Tools insulated screwdriver is simple. Just pick up the tool by its comfortable Cushion - Grip handle. Insert the #2 Phillips tip into the screw head and turn it to loosen or tighten. When using, always make sure you're working within the 1000V limit to ensure your safety. Keep it away from extreme heat as the handle is flame - retardant but not fireproof. After each use, wipe it clean with a dry cloth. Store it in a dry place to prevent the steel from rusting. This will help keep your screwdriver in good condition for a long time.
