The Makita 18Vx2 LXT 25cm BL Chainsaw Bare Unit DUC256Z is ideal for professional and DIY use thanks to its sheer power and durability. It features variable speed control for optimal user control and a brushless motor for long life and sustained power under load. For versatility and safety, it includes a kickback brake and an electric brake. Designed for quick and easy chain adjustment to boost productivity, it also has an oil capacity display to prevent running out of oil unexpectedly. The torque boost mode temporarily increases the current limit for faster cutting of thicker, harder branches. A metal spike bumper firmly grips workpieces for increased control, making cutting easier and safer. Model DUC256Z is powered by two 18V Li-ion batteries in series, supplying energy to the 36V DC motor drive system. This 36v DC motor delivers more power and run time without leaving the 18v Lithium-ion platform. When batteries of different capacities are used together, the machine stops when the battery with less capacity is depleted. Twin 18v machines require two 18v batteries with charge to operate.
