4. Maintenance
This section describes the steps of lamp maintenance. Be sure to read and understand the
safety instructions before starting maintenance. If a new lamp is used to replace an existing
lamp, it is necessary to confirm whether the lamp model is correct through the label at the
bottom of the lamp before replacement. If the internal parts of the lamp need to be replaced,
it is also necessary to confirm that the model of the replaced parts is the same as the
prototype number. For more information, please refer to the spare parts list in the manual
or contact our company for assistance.

Using incorrect combination of washer, bolt and nut will cause serious
damage to product installation and cause a variety of safety risks.
Ignoring these warnings may result in equipment damage or airport foreign
objects.
CAUTION
When a light fixture is removed from the base, a cover or a spare lamp must
