Complete flushing
If working with dual component materials, the pot life must be observed.
The unit must be flushed and completely cleaned with the appropriate sol

vent within the pot life given by the material manufacturer.
1.
Flush the pump at first through the drain hose, as described in chapter
5.2.4 on page 29 (work steps 1-16).

7.
Exchange the flushing agent drum for a clean one with new flushing agent
and repeat the complete flushing procedure (via the drain hose and the
spray gun).
5.3.2
Disassembling and cleaning the fluid pump
WARNING
Despite releasing the pressure, material congestion or agglomeration of
material may mean that there are residual pressures still present. These may
suddenly release during disassembly work and can result in serious injuries.
➤
You must be particularly careful during disassembly work!
➤
When disconnecting material hoses you should cover the screw fitting
with a cloth to catch any escaping material sprays.
CAUTION
The parts of the fluid pump are heavy. At best, work In pairs and position a
soft mat to catch falling parts.
