Suction filter
The mesh size of the standard filter is 50 mesh. 80 and 100 mesh filters
are available and can be changed by opening the top lid of the filter.
Check the O-ring before replacing the lid and replace it if it is damaged.
ATTENTION! For better sealing between the lid and the O-ring,
coat the area between the joint and the lid with grease. This will
make the O-rings seal and avoid suction of false air.
Pressure damper
The air pressure of the pulsation damper (321 pump) is factory-set at 2
bar to match spraying pressures between 3 and15 bar.
When spraying with different pressures than this, you must change
the pressure of the damper. Follow the list to adjust it to the correct
pressure. This table is also engraved on the damper.

Diaphragm pump
Before starting to use the machine, make sure the diaphragm pump is
well greased to prevent wear.
The pump is greased from factory, but should be greased again during
bedding in and then every 50 hours.
