1.9 Care and Maintenance
1.9.1 Cleaning
Before cleaning the balance, unplug the AC adapter from
the wall outlet.
Please do not use any aggressive cleaning agents (solvents
or similar agents). Instead, use a piece of cloth which has
been wet with a mild detergent (soap). Make sure that no
liquid enters the balance housing. After cleaning, wipe down
the balance with a soft, dry piece of cloth.
Carefully remove any sample residue/spilled powder by
using a brush or a hand-held vacuum cleaner.
1.9.2 Safety Inspection
If there is any indication that safe operation of the balance
with the AC adapter is no longer guaranteed, turn off the
power and disconnect the equipment in a secure place to
ensure that it cannot be used for the time being.
Safe operation of the balance with the AC adapter is no
longer ensured when
- there is visible damage to the AC adapter;
- the AC adapter no longer functions properly;
- the AC adapter has been stored for a relatively long
period under unfavourable conditions.
In this case, notify your nearest supplier. Only service
technicians who have access to the required maintenance
manuals are allowed to perform maintenance and
repairwork on the equipment.
The electrical and electronic components used in the
balance are rated to at least Class KSF according to DIN
40040.
