CAUTION:
ENSURE THE LAMP ASSEMBLY IS WELL SUPPORTED TO PREVENT
THE ASSEMBLY FROM ROLLING OFF THE WORK BENCH.

(a) Remove the five screws (Figure 56, item 11) (109753) from the front lens ring
(Figure 56, item 10) (037037).
NOTE: The front window seal (Figure 56, item 7) adheres to the front outer case

and requires refitting.

(Figure 56, item 8) (037143). Retain the O-ring and re-use in Step 2 unless the O-ring is
damaged
perished or broken
in which case it must be replaced.

lamp sub-assembly (item 1) (032055) as a single piece.

(Figure 56, item 3) (V780) which is adhered to the outer surface of the inner case.
NOTE: After removing the lamp sub-assembly, place the sub-assembly on the lamp
assembly jig (if available) to prevent accidental movement of the assembly.
