Searchlight Maintenance
For best performance, clean the searchlight’s front lens with window cleaner or
rubbing alcohol. Periodically wipe down the body of the searchlight with a damp
cloth, especially in marine environments where the housing is exposed to salt.
Focusing the Lamp
If the searchlight is dropped or receives a heavy impact from transportation or
shipping, it may be necessary to refocus the lamp to insure proper operation and
maximum output. Refocusing the lamp involves centering the lamp in the reflector.
1.
Use the 1/16” Hex Driver that is included
with the Maxa Beam Searchlight to
remove the two focus access screws and
washers that cover the X and Y Focus
Access Points.*
2.
Turn the searchlight on and shine the
beam onto a flat surface approximately
25 meters away.
(In general, ranges from
15 to 100 meters will suffice but at further
distances it will become more difficult to see
the precise adjustments taking place as the
lamp is focused.)
3.
Insert the hex driver into one of the focus access points. A slight rotation and/or
side to side motion may be required until the hex driver becomes properly seated
into the internal adjustment screw hole.
4.
After the hex driver has been inserted into the adjustment screw, turn the driver
slightly to rotate the screw. Notice how the hot spot of the beam moves on the
target. Rotate the driver until the hot spot is centered in the beam on this axis.
5.
Repeat steps 3 and 4 for the other internal adjustment screw in the other focus
access point. Continue to switch between the X and Y focus access points until
the hot spot is centered on both axes.
6.
Adjust the searchlight’s beam width out to flood and then back in to spot. If you
notice that the light’s focus has changed as you bring the beam back into spot,
adjust the focus of the light and then repeat the process of increasing the beam
width to flood and decreasing it to spot until the focus remains consistent.
7.
Replace the focus screws and washers when focusing is complete.
*The MBPKG-E Series Searchlight must first be removed from its enclosure in order to access
the X and Y Focus Points. To do so, use a 9/64” Hex Driver to remove the housing screws
and washers around the back plate of the searchlight. Grasp searchlight’s handle and pull the
searchlight straight out of enclosure tube. See diagram on page 13 or consult the Instruction
Sheet included with that MBA-2400-E Lamp Replacement Kit for further details.
