Sawing /♦Xe Before proceeding to your job, read "For Safe Operation” section. It is recommended to practice the sawing of easy logs. This also helps you get accustomed to your unit. • It is not necessary to force the saw into the cut. Apply only light pressure while running the engine at full throttle. • Racing the engine with the chain seized in a cutway can damage the clutch. If the cutting head should be caught in the cutway, do not attempt to pull it out by force, but use a wedge or a lever to open the way. Felling a tree 1. Decide the felling direction considering the wind, lean of the tree, location of heavy branches, ease of job after felling and other factors. 2. While clearing the area around the tree, arrange a good foothold and retreat path. 3. Make a notch cut one-third of the way into the tree on the felling side. 4. Make a felling cut from the opposite side of the notch and at a level slightly higher than the bottom of the notch. /jX^When you fell a tree, be sure to warn your neighbouring workers of the danger.

' Read the instructions in "For Safe Operation" to avoid kick-back of the saw. Case 1. Saw down to the halfway, then roll the log over and cut from the opposite side. Case 2. In area A, saw up from the bottom one-third of the way and finish by sawing down from the top. In area B, saw down from the top one-third of the way and finish by sawing up from the bottom. Case 3. (In limbing) First check to which side the limb is bent. Then make the intial cut from the bent side and finish by sawing from the opposite side. /[\Be alert to the springing back of a I cut limb.
