Sawing ¦ FELLING A TREE Notch cut Felling direction Felling cut 1. Decide the felling direction considering the wind, lean of the tree, location of heavy branches, ease of completing the task 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. When you fell a tree, be sure to warn neighboring workers of the danger. Bucking and Limbing • Always ensure your foothold. Do not stand on the log. • Be alert to the rolling over of a cut log. Especially when working on a slope, stand on the uphill side of the log. • Follow the instructions in “For Safe Operation” to avoid kickback of the saw. Before starting work, check the direction of bending force inside the log to be cut. Always finish cutting from the opposite side of the bending direction to prevent the guide bar from being caught in the cut. A log lying on the ground Saw down halfway, then roll the log over and cut from the opposite side. A log hanging off the ground • Before proceeding to your job, read the section “For Safe Operation”. It is recommended to first practice sawing easy logs. This also helps you get accustomed to your unit. • Always follow the safety regulations. The chain saw must only be used for cutting wood. It is forbidden to cut other types of material. Vibrations and kickback vary with different materials and the requirements of the safety regulations would not be respected. Do not use the chain saw as a lever for lifting, moving or splitting objects. Do not lock it over fixed stands. It is forbidden to hitch tools or applications to the PTO other than those specified by the manufacturer. • It is not necessary to force the saw into the cut. Apply only light pressure while running the engine at full throttle. • When the saw chain is caught in the cut, do not attempt to pull it out by force, but use a wedge or a lever to open the way. • If the guide bar and saw chain becomes caught in wood while operating it, stop the engine. Do not pry the handle with excessive force. Use a wedge to remove the chain instead. GB-10 In area A, saw up from the bottom one-third and finish by sawing down from the top. In area B, saw down from the top one-third and finish by sawing up from the bottom. G3801/G3801EZ • Do not use an unstable foothold or ladder. Cutting the limbs of Fallen Tree • Do not overreach. • Do not cut above shoulder height. • Always use both your hands to hold the saw. First check to which side the limb is bent. Then make the initial cut from the bent side and finish by sawing from the opposite side. G B Be alert to the springing back of a cut limb. Pruning of Standing Tree Cut up from the bottom, finish down from the top. 7. Maintenance Before cleaning, the inspecting or repairing the unit, make sure that engine has stopped and is cool. Disconnect the spark plug to prevent accidental starting. ¦ MAINTENANCE AFTER EACH USE 1. Air filter Dust on the cleaner surface can be removed by tapping a corner of the cleaner against a hard surface. To clean dirt in the meshes, split the cleaner into halves and brush in gasoline. When using compressed air, blow from the inside. To assemble the cleaner halves, press the rim until it clicks. Note: When installing the main filter, make sure that the grooves on the filter edge are correctly fit with the projections on the cylinder cover. 2. Oiling port Dismount the guide bar and check the oiling port for clogging. Oiling port 3. Guide bar When the guide bar is dismounted, remove sawdust in the bar groove and the oiling port. Grease the nose sprocket from the feeding port on the tip of the bar. Oiling port Grease portSprocket 4. Others Check for fuel leakage and loose fastenings and damage to major parts, especially handle joints and guide bar mounting. If any defects are found, make sure to have them repaired before operating the saw again. ¦ PERIODICAL SERVICE POINTS 1. Cylinder fins Dust clogging between the cylinder fins will cause overheating of the engine. Periodically check and clean the cylinder fins in the repair specialty store. GB-11 G3801/G3801EZ 2. Fuel filter 4. Spark plug (a) Using a wire hook, take out the filter from the filler port. Fuel filter 0.65 mm Champion : RCJ-7Y NGK : BPM7Y or BPM7A (b) Disassemble the filter and wash with gasoline, or replace with a new one if needed. Note: • After removing the filter, use a pinch to hold the end of the suction pipe. • When assembling the filter, take care not to allow filter fibers or dust inside the suction pipe. 3. Oil tank With a wire hook, take out the oil filter through the filler port and clean in gasoline. When putting the filter back into the tank, make sure that it comes to the front right corner. Also clean off dirt in the tank. Oil filter Clean the electrodes with a wire brush ...
