Cleaning
Optical components
Be very careful when cleaning the optical components. The colored surface on the dichroic filters is achieved by
means of special multi-layer coatings and even small scratches may be visible. Residues from cleaning fluids can bake
onto components and ruin them.
1. Allow the components to cool completely.
2. Wash dirty lenses and filters with isopropyl alcohol. A generous amount of regular glass cleaner
may also be used, but no residues may remain.
3. Rinse with distilled water. Mixing the water with a small amount of wetting agent such as Kodak
Photoflo will help prevent streaking and spotting.
4. Dry with a clean, soft and lint-free cloth or blow dry with compressed air.
Fans
To ensure proper cooling of the fixture, it is important that the fans are free of dust. Vacuum or gently wipe the fans
clean if they are dirty.
Lubrication
Use only Martin silicone lubricant, P/N 37302003 (500 ml) or P/N 37302004 (200 ml, in applicator bottle), to lubricate
the MAC 500/E. No other lubricant is approved for use. Be careful not to get oil on drive belts or other parts.
The focus mechanism slides back and forth on 2 metal pins. These pins must be lubricated periodically with a drop or
two of silicone oil. Check the focus mechanism whenever the head is open for service and lubricate the slides if move-
ment is rough or noisy, or if the slides seem dry.
Check the rotating-gobo bearings whenever the unit is being serviced and lubricate them if movement is rough or
noisy. Apply a few drops of oil to the bearings from above. Avoid applying excess lubricant and be careful not to get
oil on the other parts.
Depending on conditions, these bearings may need to be cleaned and lubricated periodically by a qualified technician.
Apply several drops of
silicone lubricant.
Apply 1 - 2 drops of
silicone lubricant.
