English Spark plug (Fig. 24) The spark plug condition is influenced by: ○ An incorrect carburetor setting ○ Wrong fuel mixture (too much oil in the gasoline) ○ A dirty air filter ○ Hard running conditions (such as cold weather) These factors cause deposits on the spark plug electrodes, which may result in malfunction and starting difficulties. If the engine is low on power, difficult to start or runs poorly at idling speed, always check the spark plug first. If the spark plug is dirty, clean it and check the electrode gap. Re-adjust if necessary. The correct gap is 0.024˝ (0.6 mm). The spark plug should be replaced after about 100 operation hours or earlier if the electrodes are badly eroded. 0.024" (0.6 mm) Semi-auto cutting head Nylon line replacement (1) Remove the case (22) by firmly pushing inward the locking tabs with your thumbs as shown in Fig. 26. 22 Fig. 26 (2) After removing the case, take out the reel and discard the remaining line. (3) Fold the new nylon line unevenly in half as shown in picture. Hook the U-shaped end of the nylon line into the groove (23) on the center partition of the reel. Wind both halves of the line on the reel in the same direction, keeping each half of the line on its own side of the partition. (Fig. 27) Fig. 24 4˝ (10 cm) NOTE In some areas, local law requires using a resistor spark plug to suppress ignition signals. If this machine was originally equipped with resistor spark plug, use same type of spark plug for replacement. Angle transmission (Fig. 25) Check angle transmission or angle gear for grease level about every 50 hours of operation by removing the grease filler plug on the side of angle transmission. If no grease can be seen on the flanks of the gears, fill the transmission with quality lithium based multipurpose grease up to 3/4. Do not completely fill the transmission. 23 Fig. 27 (4) Push each line into the stopper holes (24), leaving the loose ends approx. 4˝ (10 cm) in length.
