SAFETY SUMMARY
WARNING precautions in the Manual (Continued)
Injury due to Xenon Lamp Explosion
[At mounting] (Continued)
Do not touch the quartz glass part of the xenon lamp with bare hands. If the quartz
glass part of the xenon lamp is contaminated with dust or fingerprints, wipe it using a
gauze sheet or absorbent cotton cloth slightly moistened with high-quality alcohol. If
the xenon lamp is turned on with dust or fingerprints left on the surface of the quartz
glass part, it may cause contamination burn-in to decrease the mechanical strength of
the glass part, resulting in explosion of the xenon lamp.
Be sure to mount the xenon lamp in the specified direction.
If the mounting direction (polarity) is wrong, the cathode will be consumed significantly
to disable turn-on of the lamp.
Mount the lamp so that the '+' (anode) mark on it will be positioned at the support
metal of the lamp holder.
If the lamp with its cathode consumed excessively is used continuously, pressure
inside the lamp bulb may become too high, causing possible explosion. To prevent
this, replace the lamp with a new one immediately if its cathode has been consumed
substantially.
If the nut on the lamp base and wiring part is loose, the contact resistance between
them will increase due to poor contacting. This could generate a large amount of
heat to make the lamp extremely hot, resulting in possible explosion. To prevent
this, be sure to tighten the nut securely.
[At disposal]
The xenon lamp is filled with high-pressure gas (approx. 1 MPa at room temperature,
approx. 4 MPa under operating condition), and this high-pressure gas still remains in
the xenon lamp after it is demounted for replacement. For disposal of the used xenon
lamp, wrap it with a thick cloth (e.g., triple-folded cotton cloth) completely and crush
its glass part with a hammer or the like. Then, discard the xenon lamp as a
dangerous waste item properly. If the xenon lamp is discarded without being crushed,
it could explode due to possible impact at the time of disposal, scattering glass pieces
to cause personal injury.
