| - | 2. Switch stabilizer to "AUTO" | + | |
| - | 3. Put cup in -- when putting in L.E. cup at high terminal voltage be prepared to run belt charge down as terminal voltage will increase when the beam loading is removed. | + | 3. Slowly turn the CONTROL GAIN to zero while watching the grid voltage. If the grid voltage rises above -5 volts, reduce the CHARGING VOLTAGE to keep the grid voltage less than -5 volts, then continue reducing the CONTROL GAIN to zero. |
| - | 4. Switch stabilizer to "STANDBY". | + | |
| - | 5. Turn "GRIDDED VOLTAGE TUBE LENS" down and then push the " button. | + | 4. Turn the CHARGING VOLTAGE dial down to 0.10 |

| - | 11. Run magnets and quadrupole lenses down ( coarse to zero, fine to 500), the punch the "power" button. | + | 7. Turn the TERMINAL VOLTAGE dial to zero. |
| - | 12. Turn the beam profile monitor (BPM) to "STANDBY" | + | |
| - | 13. Turn buncher and chopper power to "OFF". | + | |
| - | 14. Run low energy extension (L.E. EXT.) einzel lens down. | + | |
