1.4 WARNINGS AND CAUTIONS ON HANDLING
WARNING
1 The oscillator output mirror and focusing lens on the
machining head both have a substrate made of ZnSe (zinc
selenide), a toxic substance. Therefore, do not touch the
mirror or lens with your bare hands if it is damaged.
Inhaling ZnSe dust may cause difficulty in breathing,
completely stopping the breathing of the victim in the worst
case.
If you accidentally touch the mirror or lens with your bare
hands, wash your hands well under running water.
If you accidentally inhale ZnSe dust or debris, seek medical
advice immediately.
2 If the laser oscillator must be moved, entrust the work to
the machine tool builder whenever possible. If performed
by inexperienced personnel, the oscillator may topple or be
dropped, resulting in a potentially fatal accident.
When the machine tool builder is not available to move the
oscillator, follow the procedure described on the hanging
method label. While moving the oscillator, stand well clear
and never pass under the oscillator.
3 Do not allow any dangerous or high-pressure gas to get
into the oscillator housing. The oscillator cabinet has a
hermetic structure (dustproof and dripproof), it cannot be
ventilated easily.
1) Flammable gases such as oxygen can cause a fire or
explosion.
2) Toxic gases can harm operators during maintenance.
3) Organic gases can degrade machining performance.
4) High-pressure gases can damage a panel or the
cabinet, resulting in injury from flying matters.
If such a gas accidentally gets into the oscillator housing,
remove a panel for ventilation. The installation room must
be also well ventilated.
To purge the oscillator housing, use purified, low-pressure
air or nitrogen.
4 Those who use a cardiac pacemaker must avoid
maintenance and inspection work during the discharge of
the oscillator because the electromagnetic waves
generated during the discharge may affect the operation of
the pacemaker.
If you feel sick or out of condition, either immediately leave
the spot or stop operation.
