CAU TION
It is important to follow the procedure described below in removing
the crucible mounting screws. The compressed O-ring exerts
considerable upward force against the crucible, and the
counter-pressure exerted by the mounting screws must be relieved
evenly to prevent damage to the screws or the threads in the crucible
mounting flange.
(a) Remove the two screws in the back of the crucible.
(b) Rotate the crucible 180° and loosen the six remaining screws ½ turn, beginning with the
two screws that are now in the rearmost position.
(c) Remove these six screws, beginning with the two in the rearmost position.
Step 11. Screw the knurled thumb screw into the tapped hole pro vided for it in the top of the cru ci ble.
Then ro tate the cru ci ble so that the off-cen ter thumb screw is to ward the rear of the source.
