The DeWalt DCM575X1-QW is not a superfluous luxury if you frequently use a chainsaw. The carbon brushless motor runs on a 54 volt 9.0 Ah Li-Ion battery that you also use for your other DeWalt XR garden tools. Thanks to the variable pull switch you start the engine easily and benefit from an improved control during sawing. The chain lubrication is automatic, which means less time is spent on interim maintenance. If you have to stretch the 40 centimeter Oregon chain, you do that without any tools. The rubber handle ensures that you use the DCM575X1-QW comfortably during longer use.
