The Einhell GH-EC 2040 Electric Chain Saw is handy, efficient & reliable. Ideal for sawing firewood, thinning out scrub or cutting down small trees, it has a quality rail & chain from Oregon to ensure optimum performance during use. The chain can be tensioned & changed quickly & easily & without the use of tools, while the robust metal gearing is extra high-quality for good power transmission & a long service life. User safety is paramount & the kickback protection facility has an instant mechanical chain break stopping the tool immediately if it rears up suddenly. The large window makes it easy to check how much oil is in the oil tank & the large capacity filler opening makes it easy to refill the oil. For safety in the event of the chain jumping off the rail, there is a chain catch bolt. A robust claw stop made from metal ensures safe handling, & it also serves as a pivot point when sawing horizontal trunks. A stress-relief clip protects the power cable.
