Any maintenance work should only be carried out by qualified technicians.
To ensure the continuous rotation of the rotating gobos and linear motion of the lens for focusing, it is
recommended that the bearings for the rotating gobos and the 3 shafts for the focusing lens holder be
lubricated periodically, preferably every two months. Use only high quality, high-temperature resistant
grease instead of any type of oil. When lubricating the bearings, a syringe with a fine needle is the
easiest way to introduce the grease to the bearings around each gobo.
To ensure the reliability of the projector it should be kept clean. It is recommended that the fans
should be cleaned every 15 days. The lens and dichroic colour filters should also be regularly cleaned
to maintain an optimum light output.
Do NOT use any type of solvent on dichroic colour filters.
Cleaning frequency depends on the environment in which the fixture operates: damp, smoke or
particularly dirty surroundings can cause greater accumulation of dirt on the unit’s optics. A soft cloth
and typical glass cleaning products should be used in cleaning. It is recommended to clean the
external optics at least once every 20 days and clean the internal optics at least once every 30 / 60
days.
Do not use any organic solvent, e.g. alcohol, to clean the reflector mirror, dichroic colour
filters or housing of the apparatus.
