4. Clean the coated side of gobos with dust and oil-free compressed air only.

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 aerial effect gobos
Important! The gobo can fall out if the spring is inserted backwards.
Do not lubricate gobo bearings: excess grease can cause loss
of step.
Correct gobo orientation is critical. Read the guidelines in
Figure 24 carefully before installing a gobo.
To replace a gobo:
1. Open the top cover as described under “Replacing a color filter”
on page 39.
2. Note the positions of connectors, unplug them, remove the two
Torx 20 screws that hold the effects module in the head and
remove the module.
3. Rotate the aerial effects wheel
until the gobo you want to
replace is accessible.
4. See Figure 22. Loosen the two
Torx screws (arrowed) on the
goboholder retaining clips on
either side of the gobo and
slide the clips outwards to
release the gobo.
5. Holding the goboholder by its
teeth, lift it out of the wheel.
6. With a small screwdriver or
similar, unhook the end of the
gobo spring furthest from the
gobo and pull out the spring.
Drop the gobo out of the
holder.
7. Refer to Figure 21 and Figure
24. Hold the gobo over the
holder with the side that must
face towards the lamp facing
upwards, towards the spring .
See Figure 23. Line up the
mark
A in the new gobo with
the magnet B in the holder (the
marks in gobos are also visible
at the top of each gobo in
Figure 14 on page 24).
8. Place the gobo in the holder
and Insert the spring with the
narrow end against the gobo
as shown in Figure 21.
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.
9. Check that the gobo is seated flush against the holder and that the spring is pressed as flat as possible
against the back of the gobo.
