Cleaning
• Before cleaning, visually check the disassembled parts for

after cleaning. Replace any part that appears defective.
• Immerse the disassembled parts in a non-flammable solvent (a
5 to 10 aqueous solution of Oil Clean from New Hope Co., Ltd.).
Take out the parts and blow them dry with compressed air. Re-
move any hard deposits with a stiff brush or plastic scraper.
• Again, immerse the parts in the solvent.
• Blow them dry using compressed air.
Inspection: Spacer outside diameter
• If the measurement is less than the specified limit, replace the
spacer.
