7. MAINTENANCE
• Changing the colour filters
Having opened the projector, identify
the filter to be changed, grip firmly
between thumb and forefinger and
push against the spring clip (32) until
free of the fixed clips (33). Bend the fil-
ter outwards and remove. Offer the
new filter to the spring clip (32) and
anchor behind the two fixed clips (33).
• Changing metal gobos
Having opened the projector, identify
the gobo to be replaced and push gen-
tly toward the clips (34) until free. Take
the selected replacement from the
holder (35) on the gobos/iris plate.
Offer the new gobo to the two clips,
push gently and locate behind the
remaining clips, checking for flatness.
• Routine cleaning
To maintain the light output of the pro-
jector undiminished, parts that tend to
accumulate dust and grease must be
cleaned periodically.
In most circumstances, the projector
will give long and trouble-free service if
these simple guidelines are followed.
To remove dirt from the lenses and fil-
ters, use a soft cloth moistened with
any liquid detergent suitable for clean-
ing glass.
• Lubrication
To ensure that rotating gobos and
prisms continue to operate smoothly,
the bearings should be lubricated with
oil every six months: use only Kernite
LUBE K AHT (p/n 164028/801).
Apply the oil using a syringe with a fine
needle.
Avoid over-lubricating, as excess oil
could be spattered during rotation
• Lubrication of mirror head clutches
Check periodically that the grease
applied to the mirror pan and tilt clutch-
es is in good condition; if not, remove
and regrease with Kernite LUBE-K-AC
(p/n 104034/801) to ensure smooth
and even movement of the mirror.

IMPORTANT: for uniform distribution of the light beam, the lamp must be positioned
so that the glass pip (31) on the bulb does not coincide with the optical axis of the
projector. With this in mind, locate the pip as high up as possible.
CAUTION: The projector uses a high pressure discharge lamp with
external starter.
- When fitting a new lamp, read the manufacturer’s instructions carefully.
- The lamp must always be changed without delay if damaged or deformed
by heat.

IMPORTANT: isolate the projector from the electrical power supply before com-
mencing maintenance work of any description.
The maximum temperature on the outer surface of the projector under normal
operating conditions is 90 °C (194° F).
After switching off, do not remove any part of the projector for at least 10 min-
utes, as indicated on the lamp change label (1).
Once this time has elapsed, the risk of a lamp exploding is practically zero. If the
lamp needs changing, wait a further 20 minutes to avoid the risk of burns. In the
event of a lamp exploding, the appliance is designed to prevent fragments of
glass from being scattered. Lenses and clear filters supplied with the appliance
must be fitted at all times, and if visibly damaged must be replaced promptly with
genuine spares.
• Opening the projector
Free the access cover (12) by loosening the knob (28), and remove from the projector.
Once the necessary work has been completed, refit the cover (12) and retighten the
knob (28).
• Changing the lamp
Open the projector, loosen the two side nuts (29) of the lamp to be changed and
remove it from the supports (30).
Remove the new lamp from its packaging, loosen the two side nuts (29) and locate
the lamp in the supports (30). Finally, retighten the nuts.

Important:
do not use solvents or alcohol
Parts that need cleaning frequently.
Parts that need cleaning monthly.
The gobo wheel can be cleaned with a
paintbrush.
Internal components should also be
given a general clean once a year, dis-
lodging dust and dirt with a brush and
removing it simultaneously with a vacu-
um cleaner.
