Using the Milwaukee 2809 - 20 M18 FUEL Super Hawg is straightforward. First, make sure you have a fully - charged M18™ battery. Insert the battery into the drill. If you need more control, attach the side handle. Use the chuck key to secure your drill bit in the 1/2' keyed chuck. When drilling, start at a low speed, especially for larger holes. The mechanical clutch in low speed will help you control the drill better. The LED light on the drill can be used to illuminate dark work areas. Remember to let the drill do the work and don't force it too hard. As for maintenance, keep the drill clean. After each use, wipe it down with a dry cloth. Check the chuck regularly for any debris and clean it if necessary. Store the drill in a dry place. Also, make sure to follow the battery charging instructions to keep the battery in good condition.
