Installing Gobos
Make sure fixture is cool and disconnected from power mains before any service.
Do not touch gobos with bare fingers.
Care must be used when removing and replacing individual rotating gobos. Take precautions
not to scratch or damage either the glass or metal gobos. The use of cotton gloves will keep
finger prints off of gobos.
1. Remove fixtures covers to gain access to the gobo wheel. Physically rotate the Rotating
Gobo wheel to gain access to the selected gobo.
2. Locate the Retaining Clip that secures the gobo in the rotating bearing. Pull the ends of
the clip toward the center of the bearing unit it releases from the retaining groove and can
be withdrawn.
3. Carefully remove the spring and gobo.
4. Place the new gobo in the bearing. If the gobo is a textured effect, install the smooth side
toward the lamp. If the gobo is a dichroic (glass litho), install with the coated side away
from the lamp. To find the coated side, place a pointed object such as a small screw
driver or pen against one side of the gobo. View at an angle such that the reflection of
the pointed object can be seen on the surface of the gobo. The reflection will appear to
meet the object on the coated side (place toward lamp) and on the uncoated side there
will appear to be a slight gap between the reflection and the object.
5. Replace the clip making sure it is securely seated in the retaining groove. Be careful not
to scratch gobos when reinstalling the Retaining Clip.
6. Clean finger prints from the gobo using a soft lint free cloth or tissue and either Isopropyl
or Denatured Alcohol.
