36 BEST BOY 4000 ® SPOT LUMINAIRE FIELD SERVICE MANUAL
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
WARNING: Remove power from luminaire before performing any maintenance procedures.
To replace a gobo:
Step 1. Remove power from luminaire.
Step 2. Remove R1 Cover. (Refer to "Removing Head Covers" on page 24.)
CAUTION: Do not touch gobos with bare fingers. Wear cotton gloves or finger cots when handling.
Step 3. Using fingers, grasp frame of each gobo and pull out of wheel (Figure 3-11). Remove ALL gobos.
