Replacing rotating 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 23 carefully before installing a gobo.
To replace a gobo:
1. Open the top cover as described under “Replacing a color filter”
on page 41.
2. See B in Figure 21 on page 42. Rotate the relevant gobo wheel
until the gobo you want to replace is accessible.
3. Grasp the holder by the teeth and pull the holder lightly away
from the gobo wheel to release the holder and remove it from
the wheel.
4. 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.
5. Insert the new gobo in the holder with the side that must face towards the lamp facing upwards, towards
the spring (see Figure 22 and Figure 23).
6. Insert the spring with the narrow end against the gobo, as shown in Figure 22. 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.
7. Check that the gobo is seated flush against the holder. Press the spring as flat as possible against the
back of the gobo.
8. Check that the goboholder is the right way up (see Figure 21), then work the rim of the gobo holder
under both clips and snap the gobo holder back into position on the gobo wheel. If necessary, a small
screwdriver or similar tool may be used to pry the clips away from the wheel.
9. If no further service work is to be carried out, reinstall the top cover with its safety wire and release the
tilt lock.
