Use axes or chainsaws to fell trees using knowledge of tree characteristics and cutting techniques to control direction of fall and minimize tree damage.
<ul><li>Stop saw engines, pull cutting bars from cuts, and run to safety as tree falls.</li><li>Appraise trees for certain characteristics, such as twist, rot, and heavy limb growth, and gauge amount and direction of lean, to determine how to control the direction of a tree's fall with the least damage.</li><li>Saw back-cuts, leaving sufficient sound wood to control direction of fall.</li><li>Clear brush from work areas and escape routes, and cut saplings and other trees from direction of falls, using axes, chainsaws, or bulldozers.</li><li>Measure felled trees and cut them into specified log lengths, using chain saws and axes.</li><li>Assess logs after cutting to ensure that the quality and length are correct.</li><li>Determine position, direction, and depth of cuts to be made, and placement of wedges or jacks.</li><li>Control the direction of a tree's fall by scoring cutting lines with axes, sawing undercuts along scored lines with chainsaws, knocking slabs from cuts with single-bit axes, and driving wedges.</li><li>Trim off the tops and limbs of trees, using chainsaws, delimbers, or axes.</li><li>Select trees to be cut down, assessing factors such as site, terrain, and weather conditions before beginning work.</li><li>Maintain and repair chainsaws and other equipment, cleaning, oiling, and greasing equipment, and sharpening equipment properly.</li><li>Insert jacks or drive wedges behind saws to prevent binding of saws and to start trees falling.</li><li>Tag unsafe trees with high-visibility ribbons.</li></ul>
