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

Lubrication

The MAC III Wash 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 19) 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.
4. See Figure 20. Lift the two effect module wiresets A out of their cutouts in the head chassis. Note the
positions of the three color mixing connectors (DC = PL 14, Fan = PL4, I/O = PL19) and two internal
barndoors connectors (DC = PL15, I/O = PL5) on the PCB B in the head, then unplug the connectors.
5. See Figure 21. Remove the two Torx 20 effects module retaining screws C and slide the focus car D fully
towards the front of the fixture.
