The light assemblies can be serviced in the field, but it is recommended to limit field
maintenance to cleaning the prisms. It is recommended to replace the inset lights
at regular intervals and to have them overhauled in the maintenance shop. The
same applies to lights found unserviceable in the field.

Siemens Airfield Solutions designed a set of workshop jigs for dismantling and re-
assembling the fittings.

The assembly's service life depends to a large extent on its waterproofness. All
metal mating surfaces and seals must be clean, smooth, dry and free of all foreign
particles if the light fixture is to operate for extended periods without requiring
maintenance.

Greasing of O-ring seals may be required as indicated in this manual.

Preventive maintenance of the light fixtures should be performed as listed in the
table on the next page.

Maintenance frequency depends on the conditions under which the runway is used
(i.e. climate, traffic, etc.). The recommended practices for maintenance are
described in the FAA advisory circular AC 150/5340-26.
