3.MAINTENANCE
3.1. Cleaning ABS Components
To clean dry surfaces and avoid smudging, use clean non-colouring cloths
made of cellulose or cotton. You can use a solution of water and detergent
(soap, dishwashing detergent, glass cleaner). Gently rub the dirty surface and
let it dry. Repeat the cleaning process if necessary.
In the case of hard to remove contamination, e.g. residues of adhesive, rubber,
resin, polyurethane foam etc., you can use special cleaning agents based on
a mixture of aliphatic hydrocarbons that do not dissolve plastics. Before using
the cleanser, for all surfaces we recommend carrying out tests. Do not use
cleansers containing abrasive substances.
3.2. Cleaning Stainless Steel Components
Avoid using cleansers containing any corrosive chemicals, e.g. bleach
(with chlorine). Do not use cleansers containing abrasive substances. Always
remove the dirt using microfiber cloth to avoid damage of protective coating.
Daily cleaning routine (removal of small stains):
1. Remove the dirt using cloth dipped in warm water.
2. For best results, add a little bit of dishwashing detergent.

5. INDICATOR INSTALLATION
5.1. Unpacking and Installation
A. Take the indicator out of the packaging.
B. Connect the indicator to a weighing platform, next place the weighing
device on a flat and even surface. Keep it away from any sources of heat.
C. To level the weighing instrument turn its feet. Keep turning the feet until
the air bubble takes central position:
5.2. Start-Up
The indicator can be connected to the mains only with a power supply that
comes standard with the particular model.
