The Makita DUC254Z is an 18V top handle chainsaw that is ideal for tree surgeons. It features a fully brushless motor for long life and maximum power. The electric chain break conserves battery power and decreases the likelihood of injury and soft start ensures smooth start-ups and longer gear life. Its captive nuts prevent the loss of a nut when removing the sprocket cover to replace the guide bar or saw chain. This model is compact and lightweight for topmost portability and ease of use even with one hand.
