Cleaning
Dust and dirt will affect the quality of your results.
̈ Put a dust cover over the instrument
during breaks in work.
̈ Use dust caps to protect
tube openings, tubes without
eyepieces, and eyepieces.
̈ Remove dust with a pneumatic
rubber bulb or with a soft brush.
̈ Clean objectives and eyepieces
with special optic cleaning
cloths and with pure alcohol.
̈ When accessories are not being
used, protect them against dust.
Some components are made of polymer, or are polymer-coated.
They are, therefore, pleasant and convenient to handle. The use
of unsuitable cleaning agents and techniques can damage
polymers, so always observe the following rules:
• Never clean them in an ultrasonic bath. The polymer can
become brittle and later break.
• Never use corrosive cleaning agents or ones containing
acetone.
• Never use solvents for cleaning (except for ethanol and
isopropanol).
• With warm soapy water, wiping down afterwards
with distilled water.
• With ethanol (industrial alcohol) and isopropanol.
When cleaning with ethanol or isopropanol, adhere
to the appropriate safety regulations.
