(*) Static weighing means weighing an
object whose weight is fixed during the
entire weighing.
The machine is not a weighing device
certified for legal weighing.
- The weighing system is a precision device
that requires a lot of caution in terms of
use, cleaning and maintenance.
- Should the main grid or tray be removed,
ensure not to hit the load cells during the
disassembly and reassembly operations.
- To proceed with the weighing of the filter
holder either empty or filled with coffee
powder, place it as shown below:
- Use only original La Marzocco filters and
filter holders, identified by the following
symbol:
- Use only filter holders with double spout;
- Do not place on the scale objects
weighing more than 1kg;
- Never load more than 1 kg, to prevent
any damage to the scales;
- Use the high precision scale with care,
avoid shocks, falling objects and sudden
load peaks;
- Any object to be weighed must be placed
correctly on the scales grid.
2) Cleaning
- The cleaning of the “individual grids”
must be performed with care, without
overloading the cells;
- For proper weighing of the filter holder,
make sure the grid is clean and dry;
- To avoid contact with dirt before placing
the filter holder, clean and dry the grid;
- Please be careful during the cleaning
procedures to avoid the water dripping on
the scale and its electrical components;
- Don’t wash the scale individual grids in a
dishwasher; wash them manually instead,
then immediately dry them.
If you wash the grid under a strong
water flow, remove the magnetic support
highlighted in the figure (just pull to
detach the magnets). Make sure that the
magnets are always dry and clean.
- To clean the drain tray you need to remove
the individual grids (part 3, figure 6) first,
then the drain grille (part 2, figure 6) and
finally the tray (part 4, figure 6). Make
sure not to hit the load cells during the
disassembly and reassembly operations.
