e. Guide bar
Cleaning: Remove bar guide to remove dirt from grooves and oil inlet.
Regularly grease the pinion.
Check: Reverse the bar from time to time to avoid the effects of wear. The bar rail should always
be in place. Use a ruler to observe it. If a gap is observed between them, then the rail is normal.
Otherwise, the rail is worn out. A bar must be corrected or replaced.
f. Sprocket
Check the sprocket on signs of wear. If wearing is important, replace it with a new one. Do not
install a chain on a worn or damaged sprocket. Do not install a worn chain on a pinion.
g. Spark plug
Clean the electrodes with a wire brush and set the gap to 0.6mm if necessary.
