Replacing 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 See Figure 15. Lock the head in the upside down position and remove the bottom cover. Turn the gobo
wheels as required to access the desired position. Pull the gobo holder away from the wheel slightly to
release. Remove the gobo holder.
3 Remove the gobo retention spring from the gobo holder and drop the gobo out of the holder. Insert the new
gobo in the holder. Insert the spring with the narrow end against the gobo. 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.
4 Work the rim of the gobo holder under both clips and snap the gobo holder back into position. If necessary,
a small screwdriver or similar tool may be used to pry the clips away from the wheel.
5 Replace the bottom cover and release the pan and/or tilt locks before operating.

Color/gobo wheel

The color/gobo wheel houses four dichroic glass color filters and three static gobos as shown in Figure 14. These are
normally installed with the coated side in towards the wheel.
Replacing color filters or gobos
1 Disconnect the fixture from power and allow it to cool.
2 Lock the head in the upside down position and remove the bottom cover. Turn the color/gobo wheel as
required to access the desired position.
3 To remove, press the filter or gobo from the lamp side to release it. Remove from wheel.
4 To insert, work the filter or gobo under the retention spring and position it between the pins. The long edge
of the six-sided color filters must be precisely aligned with the inside of the hub in order to fit.
