The GARDENA Electric Chainsaw CSI 4020-X is a high-performance, inline chainsaw with best cutting results. Through the optimal weight distribution, it lies safely and ergonomically in the hand. Particularly clever is the Quick-fit System: it allows easy and problem-free installation and tensioning of the chain, at initial operation and when re-tensioning. The bar is secured and the chain tensioned perfectly in just one work step. Totally easy and without troublesome checking and readjusting! For safe operation, there is the "Quick-stop" function. This ensures that the chain stops within 0.15 seconds, thereby preventing injury through the still-operating chain. The GARDENA Chainsaw CSI 4020-X is equipped with a wrap-around handle with soft components so that you can hold the chainsaw safely and securely in any cutting position. So that your chainsaw will be ready-to-use, we supply the oil for the first use. Practical: through a viewing window, the oil level can be easily and quickly controlled. In sum: impressive power. Easy to handle - with optimal results.
