PT The Black & Decker® Medium Duty Corded Chainsaw Range is very powerful, quick and efficient. Chainsaws in this range are ideal to prune trees, cut logs or for heavy duty sawing. They have a lightweight design which means less user fatigue as well as a chain bar up to 40cm long that allows you to tackle larger jobs. All Chainsaws in this range are provided with a lock-off switch to prevent accidental starting, while the anti-kickback brake provides safety in less than 0.15 seconds.
