• Pull the chain brake / front hand guard 3 towards the front handle 13 into the "set" position as shown in Figure O. • The tool is now ready to use. NOTE: In the event of kickback, your left hand will come in contact with the front guard, pushing it forward, toward the workpiece. This will stop the tool. Fig. O 13 3 Testing The Chain Brake Test the chain brake before every use to make sure it operates correctly. • Place the tool on a flat, firm surface. Make sure the saw chain 5 is clear of the ground. • Grip the tool firmly with both hands and turn the chain saw on. • Rotate your left hand forward around the front handle 13 so the back of your hand comes in contact with the Chain brake / front hand guard 3 and push it forward, toward the workpiece. The saw chain should stop immediately. NOTE: If saw does not stop immediately, stop use of tool and bring it to a DeWALT service center nearest you. WARNING: Make sure to set chain brake before cutting. Common Cutting Techniques (Fig. A, P, Q, R, S, T) Felling The process of cutting down a tree. Be sure battery is fully charged before felling a tree so you can finish on a single charge. Do not fell trees in high wind conditions. WARNING: Felling can result in injury. It should only be performed by a trained person. • A retreat path should be planned and cleared as necessary before cuts are started. The retreat path should extend back and diagonally to the rear of the expected line of fall (see Figure P). Fig. P RETREAT DIRECTION OF FALL English • Before felling is started, consider the natural lean of the tree, the location of larger branches and the wind direction to judge which way the tree will fall. Have wedges (wood, plastic or aluminum) and a heavy mallet handy. Remove dirt, stones, loose bark, nails, staples, and wire from the tree where the felling cuts are to be made. • Notching Undercut - Make the notch 1/3 of the diameter of the tree, perpendicular to the direction of the fall. Make the lower horizontal notching cut first. This will help to avoid pinching of either the saw chain or the guide bar when the second notch cut is being made (see Figure Q). • Felling Back Cut - Make the felling back cut at least 2" (51 mm) higher than the horizontal notching cut. Keep the felling back cut parallel to the horizontal notching cut. Make the felling back cut so enough wood is left to act as a hinge. The hinge wood keeps the tree from twisting and falling in the wrong direction. Do not cut through the hinge (see Figure Q). • As the felling cut gets close to the hinge the tree should begin to fall. If there is any chance that the tree may not fall in the desired direction or it may rock back and bind the saw chain, stop cutting before the felling cut is complete and use wedges to open the cut and drop the tree along the desired line of fall. When the tree begins to fall remove the chain saw from the cut, stop the motor, put the chain saw down, then use the retreat path planned. Be alert for overhead limbs falling and watch your footing. Fig. Q DIRECTION OF FALL 2" (51 mm) FELLING BACK CUT NOTCH 2" (51 mm) HINGE Limbing Removing the branches from a fallen tree. When limbing, leave larger lower limbs to support the log off the ground. Remove the small limbs in one cut. Branches under tension should be cut from the bottom of the branch towards the top to avoid binding the chain saw as shown in Figure R. Trim limbs from opposite side keeping tree stem between you and saw. Never make cuts with saw between your legs or straddle the limb to be cut. 45° TREE 13
