7-2 Lens cleaning procedures
①Using the blower, blow dusts off from the lens. Air-blow cleaning is the principal cleaning method.
Proceed to the steps below only when you need to remove stubborn soils that the air-blow
cleaning cannot handle.
②Make sure that no dust is left on the lens surface. Wiping off a dusty lens surface may damage
the lens. When dusts are left on the lens surface, blow them off first using the blower as
described in the
step ①.
③Wrap the tip of a flat-end softwood stick with a piece of cleaning paper.Wrap the stick so that the
end of paper protrudes approximately 2 mm off from the tip of stick.
④Dip the tip of cleaning paper into the cleaning solution. Clean a lens with a spiral motion from the
center towards the rim of the lens. Carefully clean the lens surface so that no soiled area is left
out. Do not apply excess force when cleaning a lens. Excess force may damage the lens.
⑤If the steps above do not clean the lens sufficiently, replace the used cleaning paper with new
cleaning paper and clean the lens again.
⑥If any soil is left out, gently wipe off the soiled area with a cotton swab soaked with a little amount
of water. Since water traces may appear after cleaning with water-soaked swab, clean the lens
by repeating the steps ②and ③.
⑦Should you have stubborn soil that cannot be removed by the steps above, contact your supplier
or us.
