with a crosstip screwdriver.

Replacing the Hg and Xe lamps
on the 106 z lamp housing
Attention!
– Prior to making any assembly work,
always disconnect the power supply at
the external transformer outlet and the
microscope outlet!
– Allow the lamp housing to cool prior to
opening it (at least 15 min.), explosion
hazard!
– Never touch the glass parts of the burner
with your hands. If required, carefully
remove finger prints and dust (use alcohol
if necessary).
– Adjust lamps immediately after ignition.
– Avoid frequent switching on and off
because this could affect the service life
and stability. Hot Hg lamps will ignite only
after cooling off. It is recommended to run
in new burners for a couple of hours
without interruption.
– Make sure that the lamp housing is
sufficiently ventilated. Never block air
slots with paper etc., fire hazard!
– It is good practice to record the hours of
use and to compare them to the manu-
facturer's specifications.
– Replace discoloured, worn burners in due
time.
– We must refuse any liability for damage
resulting from a possible explosion of the
lamp.
