This McCulloch chainsaw, the CSE 1935S is powerful and no less so than a petrol driven chainsaw despite being electric. No need to keep topping up the petrol on this chainsaw. The ergonomic shape of this chainsaw makes it possible to lop branches and saw wood at just the angle required. Automatic chain tension means you don't have to continually optimise the chain. This chainsaw will need regular oiling (before every use) to keep the chain running smoothly. There's an oil window so you can easily keep an eye on the oil level, as well as a chain brake indicator. The top speed on this chainsaw ensures the best sawing results.
