2. A periodic inspection about once a year is recommended. The inspection and maintenance interval depends on the operating conditions, the frequency of use, and the environment. If required, overhaul the lens. STORAGE CAUTION 1. Always attach the lens cap (or hood cap) and the dust cap before storing the lens. Storing the lens without these caps attached may present a fire hazard. (Very bright light, such as sunlight, may be focused by the lens and cause a fire.) NOTE 1. If the lens becomes damp because of use in fog, mist, or drizzle, wipe off the moisture with a soft dry cloth and seal the lens together with an effective desiccant in a vinyl bag to remove moisture that has entered the interior.
