8. MAINTENANCE
For faultless operation the telescope should be kept in cleanness and
protected against mechanical damage. The metal surfaces are periodically
dusted by using clean soft napkins, then wiped with a napkin impregnated
with acidless vaseline, after that with a dry napkin.
The lenses of the eyepieces are wiped with a dry linen napkin. The fat spots
are removed with a cotton wool piece impregnated with alcohol.
One should dismantle the optics only in case of necessity. In non-operating
position the telescope tube must be constantly covered with a cap and the
eyepiece one is to be plugged with a stopper.

It is recommended practice to store the telescope in the heated room with
the relative humidity of maximum 80% at the temperature from 5 to 40° C.
