Maintenance
The preferred method of maintaining these lights is to periodically and systematically replace the units
and return them to the maintenance shop for renovation. As an alternative, the units can be serviced in the
field. However, it is recommended that field servicing be limited to checking bolt torque per section 9.1
and cleaning the lens only as described in Section 10.3.
