Cleaning And Inspection

Thoroughly clean all metal parts in a metal parts cleaner and rinse in a solvent. Blow out all passages and channels in the castings with compressed air. Reverse the air flow through each passage to ensure removal of all dirt particles. NEVER USE A WIRE OR DRILL TO CLEAN OUT THE JETS.

Inspect all parts and replace any that are damaged or worn. Always use the correct repair parts.
