To repl ace rotating gobos
Important! The gobo can fall out if the spring is inserted backwards.
1. Disconnect the fixture from power and allow it to cool.
2. Position the head upside down and remove the bottom head
cover. Turn the gobo wheel to the desired position. Grasp the
holder by the teeth and pull the holder lightly towards the front
lens to release the holder and remove it from the wheel.
3. With a small screwdriver or similar, unhook the end of the gobo
spring furthest from the gobo and pull out the spring. Drop the
gobo out of the holder.
4. Insert the new gobo in the holder with the side that faces
towards the lamp facing upwards, towards the spring (see
Figure 11 and Figure 12).
5. Insert the spring with the narrow end against the gobo, as
shown in Figure 12. To identify the narrow end, press the spring
flat: the narrow end is on the inside. Push the end of the spring in under the lip of the holder.
6. Verify that the gobo is seated flush against the holder. Press the spring as flat as possible against the
back of the gobo.
7. Work the rim of the gobo holder under both clips and snap the gobo holder back into position on the
gobo wheel. If necessary, a small screwdriver or similar tool may be used to pry the clips away from the
wheel.
8. Replace the bottom cover and release the tilt lock before applying power.
