With the 40 V battery-powered chainsaw G40CS30 from Greenworks, even challenging cutting tasks such as sawing firewood, thinning shrubs, and felling small trees become much easier. The chainsaw features an automatic oiling system with a transparent tank, and the 30 cm bar length provides impeccable cutting performance for home use. Additionally, it has a two-button safety switch to prevent accidental starting of the device. All battery-powered tools in the Greenworks series can use the same battery, meaning you only need one battery to power all your Greenworks devices within the same voltage range. We recommend working with two batteries, as you can charge the second battery while using the first one. This saves a lot of time and is significantly more efficient. Please note that the G40CS30 chainsaw also requires a 40 V - 2 Ah / 4 Ah battery and a 40 V universal charger, which are not included.
