Always ensure your foothold as well as stability of the tree. 2. Be alert to the rolling over of a cut log. 3. Read 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 bending direction to prevent the guide bar from being caught in the cutaway. • Cutting an unpillowed log Saw down halfway, then roll the log over and cut from the opposite side. • Cutting a pillowed log In the area A in the picture right above, saw up from the bottom one-third and finish by sawing down from the top. In the area B, saw down from the top one-third and finish by sawing up from the bottom. • Limbing a felled tree [CAUTION!] Be alert to the spring back of a cut limb. First check which way the limb is bent. Then make a shallow cut into the compressed side to prevent the limb from being torn. Cut through from the tensed side. • Pruning [CAUTION!] 1. Do not use an unstable foothold or a stepladder. 2. Do not overreach. 3. Do not cut above shoulder height. 4. Always use both hands to grip the saw. Cut up from the bottom, finish down from the top. 6.Maintenace Before cleaning, inspecting or repairing your unit, make sure that engine has stopped and is cool. Disconnect the spark plug to prevent accidental starting. A. 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. 2. Oiling port Dismount the guide bar and check the oiling port for clogging. 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. 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 again. B. 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 after removing the air cleaner and the cylinder cover. When installing the cylinder cover, make sure that switch wires and grommets are positioned correctly in place. 2. Fuel filter (1) Using a wire hook, take out the filter from the filler port. (2) 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. 4. Spark plug Clean the electrodes with a wire brush and reset the gap to .025 in. as necessary. Note: Use a Champion RCJ-7Y or NGK BPMR7A for replacement. 5. Sprocket Check for cracks and for excessive wear interfering with the chain drive. If the wearing is found obviously, replace it with a new one. Never fit a new chain on a worn sprocket, or a worn chain on a new sprocket. 6. Front and Rear dampers Replace if adhered part is peeled or crack is observed on the rubber part. 7.Maintenace of Saw Chain and Guide Bar A. Saw Chain It is very important for smooth and safe operation to keep the cutters always sharp. Your cutters need to be sharpened when: • Sawdust becomes powder-like. • You need extra force to saw in. • The cut way does not go straight. • Vibration increases. • Fuel consumption increases. Cutter setting standards: Be sure to wear safety gloves. Before filing: • Make sure the saw chain is held securely. • Make sure the engine is stopped. • Use a round file of proper size for your chain. Chain type 33SL File size 4.5mm Place your file on the cutter and push straight forward. Keep the file position as illustrated. After every cutter has been set, check the depth gauge and file it to the proper level as illustrated. Be sure to round off the front edge to reduce the chance of kickback or tie-strap breakage. Make sure every cutter has the same length and edge angles as shown below. B. Guide Bar • Reverse the bar occasionally to prevent partial wear. • The bar rail should always be a square. Check for wear of the bar rail. Apply a ruler to the bar and the outside of a cutter. If a gap is observed between them, the rail is normal. Otherwise, the bar rail is worn. Such a bar needs to be corrected or replaced.
