§1 CAUTIONS FOR MAINTENANCE

• Be sure to use this manual after reading and understanding the operator’s manual for the DC-3300 thoroughly.

• Only properly trained service technicians can repair the system.

• During the repair, any indications are necessary to prohibit the unauthorized persons fromentering the working area and to prevent the accidents such as emitting laser to personnel.

• Wear protective goggles when the laser is emitted.

• Never look directory into the laser diode beam even if wearing goggles.

• Never point the probe tip or the laser aperture to personnel.

• Apply the lock-tight to the screws when they are loosened and tightened again.

• For maintenance, turn OFF the power and disconnect the socket from the wall-outlet unlessthis manual specifies “Turn ON the power”.

• In case that the abnormal smell and/or noise is produced from DC-3300, turn the key switch tothe OFF position immediately or press the EMERGENCY OFF button.

• When performing a maintenance with the covers (upper, lower or front cover) removed, takethe following measures in order to protect the laser diodes from static electricity.

• Spread a conductive mat on the workbench, then connect the earth wire from the mat to aground.

• Field service representative should put a wrist strap on his/her wrist, and connect the earthwire from it.

• Earth the measuring instruments such as oscilloscope and laser power meter as well.• Use a soldering iron provided with an earth wire.• Before using a tool, always touch the metal part to the conductive mat.• Connect an earth wire to the terminal on the rear panel as well.

• Specifications and design are subject to change without notice for improvement. Since theTechnical Bulletin will be released every time significant changes are made to the system, referto the Technical Bulletin together with this manual.

2. The focus of the aiming beam image is adjusted byback-and-forth position adjustment of EA04and loosening of screw G007 of EA04.

3. Adjust by the dichroic mirror AS so that the position of aiming beam image coincideswith the position of LD image. (The aiming beam image reflected on the scale turnsvertically.)

4. Remove the object lens for DC-2 optical axis adjustment jig and adjust as follows forcoinciding with the position of reflected aiming image.

1) Vertical position adjustment:Move the aiming mirror AS to the reverse direction from the displaceddirection.

2) Horizontal position adjustment:Move the aiming mirror AS to the same direction from the displaceddirection.

3) Put the object lens and adjust with the dichroic mirror AS so that theposition of aiming beam image coincides with the center of the scale.

4) Repeat steps 1 through 3, and check that it becomes as shown in the figureon the right regardless of the existence of the object lens.
