Replacing a Gobo in Gobo Wheel 1

Due to the complex gear alignment, it is best to remove ALL gobos from the wheel even when replacing or swapping
only one gobo. This way all gobos can be re-installed at one time with the proper alignment. Recalibrating a single
gobo can be a difficult process.

Parts:

Standard or Custom Gobo(s), as required. (Refer to

"Gobo Wheel Standard Configurations"

on page 9.)

Tools & Supplies:

#2 Phillips screwdriver
Cotton gloves or finger cots
