Cleaning the air filters
1. See Figure 12. On each side of the head, push on the retaining tab to unclip and remove the 2 air filter
covers.
2. In each cover, pull up on tab A and lift the retaining clip up and forward to disengage tab B.
3. Remove and clean the air filters. If they are saturated with smoke fluid, soak them in warm soapy water
and blot dry. If the filters cannot be cleaned completely or are not in perfect condition, replace them.
4. Replace each filter in its cover, then replace the retaining clips, engaging tab B in its slot and pushing
down on tab A to secure.
Important! Make sure filter retaining clips are correctly fitted and secure, or the filters will be
sucked into the fixture and cause overheating.
5. Clip the filter covers back into place on the head.

Lubrication

In general, the MAC TW1 does not require lubrication. However, depending on use conditions, the bronze
bushes and slider bars for the zoom lens car may require reapplication of the long-lasting teflon-based
grease applied at the factory. Noise when operating the zoom is a sign that lubrication is required. This
operation can be carried out by a Martin service partner if necessary.
Do not lubricate plastic bushes.

Fuse replacement

DANGER! Disconnect from power and external dimmer before opening covers. Replace
fuses with ones of the same type and rating only.
Important! The PCBs are sensitive to ESD (electrostatic discharge). Take precautions to
avoid ESD damage. Avoid touching electronic components.
The MAC TW1 is protected by two main fuses, one on the live and one on the neutral conductor. The fuses
are located on the PCB in the base unit. The circuit that supplies lamp power from an external dimmer is
also protected by two fuses. All four fuses are 20 amp, slow-blow type.
