MAINTENANCE
To prolong the service life and to ensure the maximum
performance of the searchlight, we recommend the following
maintenance guidelines :
Dirt on front glass and/or mirror reflector will result in a
considerable loss of light. Before every voyage the equipment
should be checked on these points as well as on good working of
the lamp.
Periodical maintenance is recommended at least once every three months.
Before opening the searchlight for cleaning and/or inspection of the interior the supply
must be disconnected.
Procedure :
Remove front glass and bezel assembly
Inspect the lampholder, ensure that it is free from dirt and corrosion.
Inspect the lamp. The quartz envelope must be bright and clear.
Replace if necessary.
Check all seals and rubber mountings of the mirror reflector.
Replace if necessary.
Check earthing point for conductivity
Check small ventholes in the bottom to be open
Check lamp supply cable on wear and tear.
After the inspection : Clean frontglass inside and outside, and clean the mirror reflector
with a proprietary glass cleaner. Cleaning the mirror reflector does not harm the
silvering because the silver layer is on the back of the glass.
Finally : Test searchlight for full working for 20 odd minutes.
