4 CARE, MAINTENANCE AND TROUBLESHOOTING
4.1 Care and maintenance of the instrument
Maintenance of the KF 2
ICS
is limited to the following operations:
• Cover the instrument with the dust cover after every use.
• Do not install instrument in a damp room.
• Remove dust from optical surfaces using a natural hair brush or a rubber blower.
• Remove stubborn dirt or fingerprints using commercially available optics cleaning cloths; if necessary
slightly moisten the cloths with petroleum ether. Clean the front lenses of the objectives using
petroleum ether, but do not use alcohol.
When using the KF 2
ICS
in humid climatic zones, proceed as follows:
• Store the KF 2
ICS
in bright, dry and well ventilated rooms with a humidity of less than 65%; store
particularly sensitive components and accessories, such as objectives and eyepieces, in a dry closet.
• When the equipment is stored in closed cases for a longer period of time, the growth of fungus can
be avoided by including cloths soaked in fungicide in the cases.
The risk of growth of fungus on opto-mechanical instruments always exists in the following conditions:
• Relative humidity of more than 75% and temperatures between +15° C and +35° C for more than
three days.
• Installation in dark rooms without air ventilation.
• Dust deposits and fingerprints on optical surfaces.
