Using the Milwaukee 2105 Pen Light is a breeze. First, insert the two included AAA batteries into the pen light. Once the batteries are in, you can turn the light on by pressing the on/off or momentary - on button. To use it hands - free during two - handed tasks, you can hold the pen light by the protective rubber bite zone. You can also clip it to your chest or pant pocket using the removable metal clip for easy access. When it comes to maintenance, keep the pen light clean and dry. Since it's waterproof and dustproof, you can clean it with a damp cloth if it gets dirty. However, make sure to dry it thoroughly afterwards. If the light starts to dim, it's time to replace the batteries. Remember, the limited lifetime warranty doesn't cover the batteries, so keep an eye on their performance. Avoid dropping the pen light or subjecting it to strong impacts, as this could damage the impact - resistant lens and the aircraft aluminum body.
