5.2  To think about when and after using the 

microscope 

-  The microscope should always be kept vertically when moving it and be 

careful so that no moving parts, such as the eyepieces, fall out. 

-  Never mishandle or impose unnecessary force on the microscope. 

-  Never attempt to service the microscope yourself. 

-  After use, turn off the light immediately, cover the microscope with the 

included dust-cover, and keep it in a dry and clean place.  

5.3  Electrical safety precautions 

-  Before plugging in the power supply, make sure that the supplying voltage of 

your region matches with the operation voltage of the equipment and that 
the lamp switch is in off-position. 

-  Users should observe all safety regulations of the region. The equipment 

has acquired the CE safety label. However, users do have full responsibility 
to use this equipment safely. 

5.4  Cleaning the optics 

-  If the optical parts need to be cleaned try first to: use compressed air. 

-  If that is not sufficient: use a soft lint-free piece of cloth with water and a 

mild detergent. 

-  And as a final option: use the piece of cloth moistened with a 3:7 mixture of 

ethanol and ether.  

Note:

 ethanol and ether are highly flammable liquids. Do not use them near a 

heat source, near sparks or near electric equipment. Use these chemicals in a 
well ventilated room. 

-  Remember to never wipe the surface of any optical items with your hands. 

Fingerprints can damage the optics. 

-  Do not disassemble objectives or eyepieces in attempt to clean them. 

5.5  Instructions to return your product to the supplier 

If you need to send the microscope to Jeulin for maintenance, please use the
