Lamp Change
The average lamp life is 1500 hours. For best performance and to minimize
the risk of lamp explosion, replace the lamp after 1000 hours of use.
To remove the lamp:
Remove the head shells and rear cover.
Disconnect and remove the fan assemblies from the top and bottom of the
lamp housing (1).
Turn the head so the top faces up. Pull the top of the ballast cover to
unhook from the stand-off spacers (2).
Unplug the lamp wires from the ballast (3).
Loosen the captive screws at each corner of the lamp housing assembly
(4). Move the assembly out of the way without disconnecting it (5).
Loosen the four 5.5 mm nuts that secure the lamp retaining clips (6).
Pivot the top clip away from the lamp (7). (On some models the top-left nut
may need to be fully removed.)
Remove the lamp and disconnect the lamp wires (8).
Inspect the UV shield and have it replaced if it is cracked or damaged (9).
All optical components must be in good condition to prevent injury from UV
radiation.
