WORKING TECHNIQUES Freeing a tree that has fallen badly Freeing a "trapped tree" It is very dangerous to remove a trapped tree and there is high accident risk. Never try to fell the tree that is trapped. Never work in the risk zone of the hanging trapped tree. General advice: Position yourself so that you will be clear of the tree or branch when the tension is released. Make one or more cuts at or near the point of maximum tension. Make as many cuts of sufficient depth as necessary to reduce the tension and make the tree or branch break at the point of maximum tension. The safest method is to use a winch. • Tractor-mounted Never cut straight through a tree or branch that is in tension! If you must cut across tree/limb, make two to three cuts, one inch apart, one to two inches deep. • Portable Continue to cut deeper until tree/limb bends and tension is released. Cutting trees and branches that are in tension Preparations: Work out which side is in tension and where the point of maximum tension is (i.e. where it would break if it was bent even more). Cut tree/limb from outside the bend, after tension has been released. Decide which is the safest way to release the tension and whether you are able to do it safely. In complicated situations the only safe method is to put aside your chain saw and use a winch. 115 10 82-26 Rev.2 2008-06-03 English - 29
