Select the appropriate bit from the 42 - piece Drive Bit Kit and start your fastening work. When you need light in a dark area, turn on the 49 - 24 - 0146 M12 LED Work Light. For portability, you can attach the screwdriver to your belt using the Belt Hook. When not in use, store all the items in the Soft Case. As for maintenance, keep the battery packs charged when not in use. Wipe the screwdriver and work light with a clean, dry cloth after each use.
