Section 15: Servicing the Legend
184
The RF driver for some lasers is located to the right of the laser, under the laser cover.
To service the RF, remove the laser cover. The cover is held in place with four or
five Phillips head screws. The RF is held in place by three or four Allen head screws
on the top, and three or four hex nuts on the bottom as shown in the following
diagram. You will also need to demate the power, control and RF connectors shown
in the drawing.
Keyboard/Display
The keyboard/display module for the Legend (part #LM5) is located on the cover of
the Legend. To remove/service this module, first turn the machine off and unplug the
power cord from the machine or from the wall. Open the large door. Remove the
four nuts holding the metal cover over the keyboard/display. Remove the cover. The
keyboard is now loose, and should be supported with a free hand. On the right edge
of the keyboard there is a flat ribbon cable. Push the "ears" on the connector away
from each other, and the connector should back out far enough to be easily removed.
The keyboard will now slide off the four mounting posts. Installation is the reverse of
removal.
X Beam
The X beam module for the Legend is located inside the Legend cabinet. To
remove/service this module, first, if you have not already done so, turn the machine
off and unplug the power cord from the machine or from the wall. Open the large
door, and gently pull the beam forward until it is a comfortable reach. Loosen the
Phillips head screw on the left of the beam, and the two captive screws on the right of
the beam. The captive screws have a Phillips head, and are taller than "normal"
screws. Disconnect the white flat cable from the right end of the beam. There is a
small tab on the top center of the connector that needs to be depressed to allow the
cable to be removed. The clamp, holding the cable down, needs to be removed as
well. Installation of the new beam is the reverse of the removal. Please be careful of
the mirror mount on the right side of the beam. The mirror is pre-aligned, and
alignment will be lost if you bump it hard enough.
When installing the new beam, please start all three captive screws carefully prior to
tightening any of them.
