4. Maintenance
4.1 Replacing the light bulb
Unplug the projector and allow it to cool off fully before replacing the light bulb. Never touch the light bulb with bare hands as skin fat and other particles can damage
the new light bulb. Use a soft, woolen cloth, gloves or a special glass cleaning cloth to change the light bulb (picture 8). Replace the light bulb and check if it is inserted
properly. Please, make sure to always use the correct light bulb. Type G 6,35-15.
4.2 Additional information
• Do not touch the lens with bare hands. Use a soft, cotton cloth to clean it.
• Use a glass cleaner to clean the working surface. Please do not spread it beyond the working area.
• There is a plastic lens under the glass plate which should be cleaned twice a year. Firstly, remove the safety screws and then the lens system. Remove the dust
between the lens and the working space using an antistatic cloth or a special cloth for glass surfaces.
