(F17) (1) Switch F18 Carburetor anti-freeze mechanism Operating the chain saws in temperatures of 0–5°C at times of high humidity may result in ice forming within the carburetor, and this in turn may cause the output power of the engine to be reduced or for the engine to fail to operate smoothly.
7. Operation F19 ■ HOW TO SWITCH BETWEEN OPERATING MODES (F19) 1. Flip the engine switch to turn off the engine. 2. Remove the cover to the air filter, remove the air filter, and then remove the choke knob from the cylinder cover. 3.

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.
8. Sawing F22 ■ FELLING A TREE (F22) 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.
8. Sawing F23 F24 F25 A Log lying on the ground (F23) Saw down halfway, then roll the log over and cut from the opposite side. A Log hanging off the ground (F24) 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. Cutting Limb of Fallen Tree (F25) 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.
9. Maintenance F27 WARNING Before cleaning, inspecting or repairing your 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.
9. Maintenance 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. F31 ■ 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.
9. Maintenance F34 4. Spark plug (F34) Clean the electrodes with a wire brush and reset the gap to 0.65 mm as necessary. Champion RCJ-7Y F35 ❲ 22 ❳ 5. Sprocket (F35) Check for cracks and for excesslve wear interfenng with the chain drive. If the wearing is found obviously, replace it with new one. Never fit a new chain on a worn sprocket, or a worn chain on a new sprocket.
10. Maintenance of Saw Chain and Guide Bar F36 ■ SAW CHAIN WARNING 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: WARNING Be sure to wear safety gloves. Before filing: • Make sure the saw chain is held securely. • Make sure the engine is stopped.
10. Maintenance of Saw Chain and Guide Bar F38 Make sure every cutter has the same length and edge angles as illustrated. (F38) (4) (5) (6) (7) F39 ■ 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.
11. Troubleshooting Guide Case 1. Starting failure: Make sure the icing prevention system is not working. Check fuel for water or substandard mixture. Replace with proper fuel. ➜ Remove and dry the spark plug. Then pull the starter again with no choke. ➜ Replace with a new plug. ➜ ➜ Check for engine flooding. ➜ Check the spark. Case 2. Lack of power/Poor acceleration/Rough idling Check fuel for water or substandard mixture. Replace with proper fuel. ➜ Clean. ➜ Readjust speed needles.
12. Storage 1. Empty the fuel tank and run the engine out of fuel. 2. Empty the oil tank. 3. Clean the entire unit. 4. Store the unit in a dry place out of the reach of children.
