1.5 Hints on Maintenance and
Care
To ensure perfect function of the microscope
illuminating system, it is necessary to use only
components and spares marketed or approved
by us. When in doubt, please contact our
service staff.
With the exception of the work described in this
manual, the user must not perform any repairs
or changes himself.
We would like to emphasize that all other
changes and repairs must be performed by
specially authorized personnel.
Defective instruments or components may only
be repaired and maintained by our service
department.
−
After expiry of the
average operating time
(
see data sheets from the lamp
manufacturers
), the lamps must be
exchanged to avoid the
risk of explosion
!
The operating time of the HBO 103 can be
checked on the display of operating hour
meter of the relevant transformer.
(
Fig. 6
)
With increasing service life, dirt will deposit
on the lamp bulb so that homogeneous
illumination of the object field is no longer
ensured.
−
The lamps must be exchanged as described
in
chapter 3.1
.
−
Before each lamp exchange, make sure to
allow the HBO 100microscope illuminator to
cool down sufficiently long in order to
reduce the pressure; wait at least for
15
minutes
!
−
Always disconnect the instrument from the
line before each lamp exchange or any other
work inside the instrument.
−
Clean the housing of the microscope
illuminator when it is dirty.
Do not use any solvents.
Soak a cleaning cloth in a mixture of water
and washing-up liquid, remove the dirt and
dry the housing using a clean cloth.
1.6 Advice on lamp breakage
If the HBO lamps have reached their rated
lifetime or their bulbs show advanced
blackening, they should be replaced because of
the increasing risk of explosion.
If lamps are operated properly, lamp explosion
is very unlikely.
For the rare case, that an HBO lamp bursts and
the mercury (Hg) contained in the bulb is
released, we recommend to follow this
procedure:
−
First of all, the persons being nearby should
instantly
leave the place to avoid inhaling
mercury vapor.
−
Air the laboratory thoroughly (for approx.
30 minutes)!
−
Every lamp housing of a higher-power lamp
should be equipped with an individual
exhaust device that is not connected to the
domestic air-conditioning system to avoid
that mercury vapor enters this system.
−
Once the lamp housing has cooled down,
collect any mercury residues precipitated
inside the lamp housing by using an
adsorbent available from a chemicals
supplier.
