Servicing optical components

Warning! Disconnect from power and allow to cool for 30 minutes before servicing the components
in the head.
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.
Opening the head for service access
To open the head for access to the optical components:
1. Disconnect the fixture from power and allow to cool for 30 minutes.
2. Place the product on a suitable work surface.
3. See Figure 9. Position the head so that the Martin logo on the back of the head is facing the right way up
and apply the tilt lock (see Figure 1 on page 6).
4. The user may remove the top head cover only. When the Martin™ logo on the back of the head is facing
the right way up, this cover is on the top of the head. Do not try to remove the other head cover. Loosen
the cover's two Torx 25 retaining screws (arrowed) and lift the cover up from the head.
5. If required for easier access, release the head cover's safety wire from its slot in the head chassis and
remove the head cover completely.
To close the head, follow the above steps in reverse order. Remember to release the tilt lock before
applying power or packing the MAC Quantum Profile in its flightcase.
