Safety isn't a throwaway word when it comes to felling trees and running chain saws. You must take it seriously. There are a few absolutely essential safety gear items you need to wear for any chain saw work, and especially when felling a tree: - A logger's helmet to protect you from falling branches, a major cause of logging injuries. - Earmuffs and a face screen to protect your ears and eyes. - Safety glasses to keep the dust out. - Kevlar chaps, which will stop a chain instantly should you happen to drop the bar against your leg.
