SAFETY PRECAUTIONS B-70315EN/02
s-4
WARNING
6 If there is a possibility of being exposed to CO
2
laser
radiation exceeding the maximum permissible exposure
(MPE) level for skin, wear protective clothing.
Otherwise, there is a danger of being burnt.
7 The oscillator is fitted with a red semiconductor laser to
indicate the approximate position of invisible CO
2
laser
beam. Do not look directly at the semiconductor laser
beam. Otherwise, your eyes may be injured.
NOTE
1 Warning labels are affixed to those parts of the laser
oscillator where there is a danger of exposure to laser
radiation. Observe the precautions given on the labels.
2 During installation or maintenance necessitating the
opening of an oscillator door or the removal of a panel, only
persons who have undergone maintenance training should
operate the laser. In such a case, extreme caution must be
exercised.
3 Laser products shall conform to the regulations laid down in
the laser safety standard, including that stipulating control
using a key.
The oscillator start signal (RUN ON) shall be controlled with
a key switch such that the oscillator cannot be turned on
without a specific key.
Control using a key ensures that other than the authorized
personnel cannot operate the laser oscillator. It is
extremely dangerous if a person who is unfamiliar with the
equipment attempts to operate the laser oscillator.
The shutter shall be unlocked only while a beam is being
output. Otherwise, keep the shutter locked to provide
protection should the laser accidentally be turned on.
The laser oscillator is equipped with a warning light as an
option. The warning light blinks while discharge is in
progress or whenever laser radiation is possible.
While the warning light is blinking, pay careful attention to
laser radiation and high voltages.
