1.4  Maintenance and cleaning 

 
In any event, the device must be kept clean and dusted regularly. 
If any moisture should be occur, before you wipe down the device you must ensure 
that the mains power is switched off. 
 
When  glass  components  become  dirty,  the best  way  to  clean  them  is  to  wipe  them 
gently with a lint-free cloth. 
 
To wipe oil stains or finger prints off the lens surface, moisten the lint free cloth with a 
mixture of ether and alcohol (70 / 30 ratio) and use this to clean the lens. 
 
You must be careful when handling ether and alcohol, as these are highly flammable 
substances.  You  must  therefore  keep  it  away  from  naked  flames  and  electrical 
devices which can be switched on and off, and only use it in well-ventilated rooms. 
 
However organic solutions of this type should not be used to clean other components 
of the device. This could lead to damage to the paint finish. To do this, it is sufficient 
to use a neutral cleaning product. 
 
You could also use the following cleaning products to clean the optical components: 

  Special cleaner for optical lenses 

  Special optical cleaning cloths 

  Bellows 

  Brush 

 
When  handled  correctly  and  checked  regularly,  the  microscope  should  give  many 
years of efficient service. 
 
Should repairs still be necessary, please contact your KERN dealer or our Technical 
Department.
