The Makita DUR369L LXT Line Trimmer with loop handle. Powered by 2 x 18V Li-ion batteries in series. ADT (Automatic torque Drive Technology) automatically regulates the speed during operation in order to achieve optimum performance depending on the requirements. This also preserves battery life for maximum usage. Its maintenance-free, long-life brushless motor enables 3 speed selection, controlled via a variable speed trigger. Active Feedback sensing Technology (AFT) turns the motor off if bit rotation is suddenly forced to stop. Whilst the electric brake allows for maximum productivity and increased operator safety.  Extreme Protection Technology (XPT) provides improved dust and water resistance, ideal for operation in harsh conditions. A battery protection circuit protects against overloading, over-discharging and over-heating. Supplied with three blade attachments: line head, grass blade and composite blade.
