Brushless motor - high performance, compact dimensions and longer service life enables up to 100 cuts per battery charge (when using an 18V/5Ah battery). 30 cm bar and saw chain. Motor brake - reliably stops the chain in under one second. Automatic chain lubrication - reduces maintenance work. Chain tensioning system with onboard tool - quick retensioning thanks to the built-in tool. Improved chain cover and therefore better chip ejection reduces cleaning intervals. Tool-free oil tank cap and semi-transparent oil tank for better visibility of the oil level and a new capping system for reduced oil loss. Rubberized handle and ergonomic design for fatigue-free working. Plastic claws for better leverage and more control during work. As a basic model (without batteries and charger) ideally suited for those already using 18 Volt XR or 54 XR FLEXVOLT batteries of any Ah class.
