Service and maintenance 17
Work in a clean, well lit area. Use gentle pressure only when cleaning. Do not use any product that contains
abrasives. Do not use solvents. Use care when cleaning optical components: surfaces are fragile and easily
scratched.
To clean the fixture:
1. Disconnect the fixture from power and allow it to cool for at least 30 minutes.
2. Vacuum or gently blow away dust and loose particles from the outside of the fixture and the air vents at
the back and sides of the head and in the base with low-pressure compressed air.
3. Clean the front glass on the front of the head by wiping gently with a soft, clean, lint-free cloth moistened
with a weak detergent solution. Do not rub the surface hard: lift particles off with a soft repeated press.
Dry with a soft, clean, lint-free cloth or low-pressure compressed air. Remove stuck particles with an
unscented tissue or cotton swab moistened with glass cleaner or distilled water.
4. Check that the fixture is dry before reapplying power.
Lubrication
The MAC Encore Performance does not require lubrication under normal circumstances. Moving parts can
be checked and a long-lasting teflon-based grease reapplied by a Martin service partner if necessary.
Replacing optical components
Optical components have fragile coatings and are exposed to very high temperatures. Use only genuine
Martin parts. Handle and store components with care. Wear cotton gloves while handling them and keep
them perfectly clean to reduce the risk of heat damage.
Gobos: general
The MAC Encore Performance uses specially designed borosilicate 3.3 gobos with a heavy matted
aluminum coating that require particularly careful handling and storage. The MAC Encore Performance
User Guide available for download from www.martin.com gives names, illustrations and part numbers of the
gobos installed as standard.
The use of metal gobos in the MAC Encore Performance is not recommended.
Do not use gobos with dark coatings on any side, as these will absorb heat – either directly from the LEDs
or reflected back from other gobos and optical components – and will not be durable.
