Cleaning; Lubrication - Martin RoboScan Pro 918 User Manual

5. Using either a controller or the control panel, strike the lamp and focus the light on a flat surface.
6. Center the hot-spot (the brightest part of the beam) using the 3 adjustment screws. Turn one screw at a time
to drag the hot-spot diagonally across the projected image. If you cannot detect a hot-spot, adjust the lamp
until the light is even.
7. To reduce a hot-spot, pull the lamp in by turning all three screws clockwise 1/4-turn at a time until the light is
evenly distributed.
8. If the light is brighter around the edge than it is in the center, or if light output is low, the lamp is too far back
in the reflector. "Push" the lamp out by turning the screws counterclockwise 1/4-turn at a time until the light
is bright and evenly distributed.

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.

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.

The focus mechanism slides on 2 metal pins that must be lubricated periodically. Check the focus mechanism when-
ever the fixture is open for service and lubricate the slides if movement is rough. Lubricate the rotating-gobo bearings
if movement is rough on slow rotation or if they become noisy.
1. Fill a syringe with Martin P/N 37302003, "Silicone oil, 500 ml," or P/N 37302004, "Silicone oil, 200 ml, in
applicator bottle."
2. Apply a few drops of oil to both slides. The oil will be distributed by the action of the focus mechanism. Be
careful not to get oil on other parts.
3. Apply a few drops of oil to each rotating-gobo bearing from the lamp side of the wheel. Remove excess
lubricant and be careful not to get oil on other parts.
