Using your Milwaukee 2010R Rechargeable 250L Penlight with Laser is a breeze. To turn it on, simply press the On/Off or momentary - on button. You can choose between the high - brightness mode for intense light or the low - brightness mode for longer runtime. When you're doing a two - handed task, use the protective rubber bite zone to direct the light where you need it. The laser pointer is great for pinpointing specific areas during inspections. For charging, use the included 2 - foot heavy - duty cable and plug it into a USB port. Keep an eye on the on - board battery indicator. Green means the battery is fully charged, yellow indicates it's running low, and red means it's time to recharge. Always store the penlight in a dry place and use the removable metal clip to attach it to your pocket for safekeeping. Avoid dropping it from heights greater than 2M as it may damage the penlight. To maintain its performance, clean it with a soft, dry cloth regularly. Remember, this penlight comes with a 2 - year warranty, so if you encounter any problems, reach out to the manufacturer.
