A. Cover Removal
Tools required: T20 Torx Driver
1. Remove the upper and lower screws which
secure the cover to the main assembly. Do not
loosen the lower screws inside the cut out slots
in the bottom of the cover.
NOTE
The upper screws and lower screws are not the
same. Do not mix them. The upper screws are
for threading into the plastic of the front and rear
panels. DO NOT use the finer threaded lower
screws for this.

2. Carefully pull the Cover up and away from the
unit.
B. Cover Installation
1. Reverse previous procedures for cover installa-
tion.
NOTE
When installing the upper screws, attempt to reuse
the original threads. The easiest way to do this is
by turning the screw counter-clockwise until you
feel the threads line up, then begin to turn the screw
clockwise to tighten. Do not over tighten.
C. Tube Handle Replacement
Tools required: T20 Torx Driver
1. Disconnect the Torch and Leads from the unit.
2. Remove the cover per subsection 7.04-A.
3. Remove the screws securing the tube handles to
the base of the unit.
NOTE
Some of the earliest manufactured units have Tube
Handles that are joined together under the base of
the unit. Later versions are not joined together.
4. Remove the power supply from the Tube Han-
dles.
5. Replace the Tube Handles by reversing the above
steps.
6. Reinstall the power supply cover.
D. Disconnecting Front and Rear Panels from
the base
In many of the replacement procedures, it may be help-
ful to disconnect the front or rear panel from the base in
order to allow more room to access the parts.
Tools required: T20 Torx Driver
1. Remove the cover per subsection 7.04-A.
2. For earlier models remove the Tube Handles
per subsection 7.04-C. The earlier model Tube
Handles join together under the base. Later mod-
els do not and there is enough room to perform
this procedure without removing them.
3. While grasping the panel close to the base, pull
the panel directly from the base to release the
locking tabs.
4. To re-engage the panel, position the panel so that
the locking tabs are above the base, then push the
panel back onto the base until the locking tabs
engage the mating holes in the base.
5. For complete removal of panel, disconnect any
other item still attached to the panel and another
component of the power supply.
