6.2 Safety devices
6.3 Maintenance operations
Performance of preventive maintenance is not essential. Regular maintenance can, however, contribute
to identifying potential problems before they become serious, thus enhancing the instrument’s reliability
and extending its useful operating life.
Maintenance services can be obtained from your local representative or from the manufacturer.
Regardless of the accident prevention regulations or testing intervals for medical instruments prescribed
in different countries, we recommend a safety check of the device at least once a year.
6.3.1 Lamp replacement
When the lamp has operated for 450 hours (90% of the warranted life of 500 hours) a red “lamp
warning” indicator will light on the front panel. At 500 hours, the lamp warning indicator will blink
continuously until the lamp hours counter is reset. For lamp replacement instructions, see Section 4.5
Replacement of lamp . It is recommended that new lamps purchased from a source other than
KARL STORZ GmbH & Co. KG should be operated for eight hours in the light source prior to clinical use.
6.3.2 Battery replacement
Disassemble the light source as necessary, until the battery may be accessed, see Section 4.6
Replacement of attenuator assembly .
Remove the lamp timer board. The battery connections are soldered in place and must be unsoldered to
be replaced. Alternatively replace the lamp timer board.
Reassemble in the reverse order.
6.3.3 Interior cleaning
Depending on the cleanliness of the operating environment, removal of dust from the interior of the
device may be required periodically. Remove the outer cover and power supply cover as described in
Section 4.3.1 Replacement of power supply ( 20 1340 84) or Section 4.3.2 Replacement of power supply
(Z07854) . Blow dust from the device using compressed air, taking care not to direct air at the fan blades
or the attenuator screen. Reinstall the covers.
