Routine maintenance

The MAC 700 Wash requires routine cleaning. The schedule depends heavily on the operating
environment. It is essential to follow the cleaning guidelines given later in this section.
Refer any service operation that is not described here to a qualified Martin technician.
Important! Excessive dust, smoke fluid, and particulate buildup degrades performance, causes
overheating and will damage the fixture. Damage caused by inadequate maintenance is not
covered by the warranty.
Warning! Disconnect the fixture from power and allow to cool for at least 45 minutes before
removing any cover.

Tilt lock

The tilt position of the head can be locked for transportation and
service with the tilt lock. To lock or unlock the head, pull the lock
out and turn it one-quarter turn in either direction.
