d. Cleaning the oil filter and fuel filter
Clean these items regularly. Remove them from the tanks
using clamps. Clean them with gasoline and then put them
back in place afterwards
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.
