Replacing Rotating Gobos; Color/Gobo Wheel - Martin MAC 2000 Profile User Manual

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 17. 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.
