MAINTENANCE
The MAC 550 Profile requires routine cleaning. The schedule depends heavily on the operating environment; please
consult a Martin service technician for recommendations.
Refer any service operation that is not described here to a qualified Martin technician.
Important! Excessive dust, smoke fluid, and particulate buildup degrades performance and causes
overheating and damage to the fixture that is not covered by the warranty.
Warning!
Disconnect the fixture from power before removing any cover.
Tilt lock
Important! Release the tilt lock before operating the fixture.
The tilt position of the head can be locked for transportation and service
with the tilt lock. To lock or unlock the head, pull on the lock and turn it
one-quarter turn in either direction.
