REPLACING THE BULB

* Pull out the plug which is attached to the lamphouse cover.
Turn the lamphouse cover and remove it from the illumination unit.
* Loosen the two clamping screw as illustrated below, turn the clamping lever in direction of
the arrow, and remove the socket and bulb assembly.
* Remove the old bulb - use care as it may be extremely hot - and insert the new bulb into the
socket.
* Place the bulb assembly into the housing by aligning the guide with the groove in the bulb
flange.
* The groove in the bulb flange should be properly aligned with the guide, otherwise uneven
illumination will result.

necting plug.
