Using the Milwaukee 2429-20 M12 Sub-Compact Band Saw is easy. First, make sure you have a fully charged M12 battery (sold separately). Insert the battery into the saw. If you need to adjust the blade tension or tracking, use the adjustment feature. When you're ready to cut, hold the saw with one hand, and use the variable speed trigger to control the cutting speed. The LED light will help you see the cut line clearly. For safety, always ensure the dual - latching lower guard is in place. This saw is designed for cutting small - diameter materials, so don't try to cut larger items. When you're done using the saw, remove the battery. To keep your saw in good condition, clean it regularly, especially after heavy use. Check the blade for wear and replace it when it starts to dull. Remember to use only Milwaukee® 48 - 39 - 0572 Sub - Compact Portable Band Saw Blades with this tool.
