To use a pole saw safely and effectively, first extend the pole to the desired length, ensuring it is stable. Position yourself at a safe distance from the branch you are cutting. Start by making a small notch on the underside of the branch to prevent tearing, then position the saw blade on the top of the branch and use smooth, controlled strokes to cut through it. Stay alert and move out of the way as the branch begins to fall to avoid injury from falling debris.
