5. Clean the uncoated side of gobos with photographic quality lens-cleaner and optics cleaning tissues.
Use a repeated dabbing action rather than a rubbing action.
6. Avoid scratching coated and uncoated sides.
7. Never place a gobo with the coated side face-down on any surface.
8. Mount the gobo with the matted coating towards the lens.
Replacing a rotating gobo
To replace a rotating gobo:
1. Remove the top head cover as described above. If you want easier access, you can remove the
multi-module as described above, but this is not necessary.
2. See Figure 13. Turn the rotating gobo wheel until the gobo you want to replace is easily accessible.
Avoid disturbing the gobo wheel for the rest of the procedure.
3. Rotate the gobo you want to replace until the magnet (arrowed) points towards a reference position
such as the centre of the gobo wheel. The magnets in all the goboholders will now point in this direction.
4. Holding the edge of the goboholder firmly, slide the goboholder out of its clip in the gobo wheel.
5. Check that the magnets in all the goboholders are still facing towards the reference point, then slide the
new gobo into its clip in the gobo wheel with the magnet facing towards the reference point until it is held
securely.
6. Check that the gobo rotates correctly.
7. When service work is finished, reinstall the multi-module (if you removed it) and the top head cover as
described above.
