CAUTION! Do not finger the surface of the new lamp; handle it in its protective wrapping. Any fingermarks will be fired into the surface of the quartz envelope, reducing the output and life of the lamp. If the envelope is accidentally finger marked, remove the marks immediately with a cotton wool swab moistened with methanol.

CAUTION! Do not use polishes, or window cleaning aerosols and liquids for cleaning lenses. Do not touch the inner surfaces, (those facing away from the workpiece), of the projection or condenser lens. The projection lens is the most critical; a finger mark on the inner surface will degrade the quality of the projected image.

• Remove any accumulated dust with a photographic lens brush.

• Remove any grease or fingermarks with a new photographic cleaning tissue, which may be moistened with methanol if necessary.

CAUTION! The mirror should be cleaned as infrequently as possible. It is recommended that cleaning is performed by an authorised service engineer. Do not finger the surface of the mirror.

• If necessary, remove loose dust with a photographic lens brush.

• If necessary, remove grease and finger marks with surgical quality cotton wool moistened with methanol. Apply the cotton wool lightly, and then polish the surface with clean dry surgical quality cotton wool.
