Lubrication; Replacing A Color Filter - Martin MAC III AirFX User Manual

Cleaning the fixture
To clean the head:
1. Power the lamp off, allow components to cool for 2 hours 45 minutes and
disconnect the fixture from power.
2. Remove both head covers by loosening their quarter-turn retaining
screws (see Figure 20).
3. Vacuum or gently blow away dust and loose particles inside the head
with compressed air.
4. Carefully clean the optical components, but note that special precautions
apply to the gobos (see "Aerial effects in the MAC III AirFX" on page 40).
Remove smoke and other residues with cotton swabs or unscented
tissues moistened with isopropyl alcohol. A commercial glass cleaner
may be used, but residues must be removed with distilled water. Clean
with a slow circular motion from center to edge. Dry with a clean, soft
and lint-free cloth or compressed air. Remove stuck particles with an
unscented tissue or cotton swab moistened with glass cleaner or distilled
water. Do not rub the surface: lift the particles off with a soft repeated
press.
5. Remove dust from fans and air vents with a soft brush, cotton swab,
vacuum, or compressed air.
6. Reinstall the head covers.

Lubrication

The MAC III AirFX does not require lubrication under normal circumstances. The slides for the zoom and
focus lens cars are lubricated with a long-lasting teflon-based grease that can be reapplied by a Martin
service partner if necessary.

Replacing a color filter

Note: Wear cotton gloves while handling color filters and use only genuine Martin filters.
1. Power the lamp off and allow the fixture to cool for 2 hours 45 minutes. Disconnect the fixture from
power.
2. The top of the head is above the text on the lamp cover with the text facing the right way up. Lock the
head in a convenient position for access to the top of the head.
3. Remove the two retaining screws (see Figure 20) from the top cover and lift it away from the head. Let
the cover hang on its safety wire or unclip the safety wire and remove the cover completely.
