Make the horizontal cut into the buttress first, followed by the vertical cut. Remove the resulting loose section from the work area. Follow the correct tree felling procedure after you have removed the large VERTICAL CUT buttress roots. Refer to “Operation – Proper Procedure for Tree Felling” earlier in this manual.
