Brushless Line Trimmer provides a max power output of 0.6kW and features a 3-stage speed control allowing the user to control the speed between 0-3,500, 5,300 and 6,500rpm. Featuring Automatic torque Drive Technology (ADT) to adjust the cutting speed according to grass density and Active Feedback sensing Technology (AFT) to shut off the motor if rotational speed of the tool suddenly drops. With a max cutting diameter of 330mm with a nylon cutting head & weighing in at 5.3kg with a BL4050F battery, the UR017G is lightweight and ideal for lawn edge maintenance on any sized property. This is a Kit/Combo. Battery & Charger are Included. Kit Includes 1 x (191B26-6) Makita 40V Max 4.0Ah Battery BL4040 The 40V Max 4.0Ah battery has been designed to be both tough & highly intelligent. This battery features digital communication not only between the battery & the charger, but also between the tool & battery, relaying tool specifications to optimise tool performance. The higher battery output is a genuine solution for heavy industrial users allowing for continuous high demand activity over extended periods of time. Built to be highly durable, the XGT batteries feature a heavy duty cell casing significantly improving the batteries impact resistance. Along with this casing, the water resistance has been significantly increased with intricate 3 layer moisture protection shield protecting the cells from water ingress. Reliable tools are a must for all professional applications, & XGT is durable & built to perform! The newly designed optimum charging system is able to achieve optimised fast charging by feeding real time battery data, such as battery condition & temperature with the charger. Dual cooling fans significantly reduce charging time as both the battery & charging circuit are cooled, allowing the charger to perform consecutive fast charges. Ensuring users have are able to stay connected with the 18V LXT platform the DC40RA is compatible with the charging adaptor ADP10 (optional accessory). With this adaptor the DC40RA is able to rapid charge 18V LXT batteries up to 27% faster than 18V rapid charging models. Ensuring the battery spends more time working & less time sitting on the charger. 3 Stage Speed Control - Sets the max spindle speed to 3,500, 5,300 or 6,500rpm to suit the application. Low Resistance Trigger - Requires minimal effort to pull the trigger reducing fatigue. Constant Speed Control - Detects the level of load & automatically adjusts power output to maintain operating speed. Active Feedback Sensing Technology (AFT) - Reduces the risk of kickback by detecting a sudden decrease in RPM & automatically stops the motor. Automatic-Torque Drive Technology (ADT) - Adjusts the rpm according to the load required to maintain speed & performance through dense grass.
