Using the Klein D275-5 Flush Cutter is a breeze. Just hold the cutter firmly by the red plastic handles. When you need to cut small wires, zip ties, or other fine materials up to 16 AWG, place the material between the jaws and squeeze the handles. The pinch - cutting feature will make the cutting easier, and you'll get a nice, flat cut. Remember, this cutter is not insulated, so don't use it on live electrical wires. Also, since it's not tether - capable, be careful not to drop it in high - up or hard - to - reach places. For maintenance, keep the cutter clean after each use. You can wipe it with a dry cloth. The heat - treated blades are durable, but if you notice the cutting performance decreasing, you might need to replace the cutter. That's all you need to know to make the most out of your Klein D275 - 5 Flush Cutter.
