Once the delivery line, hopper, delivery cylinders and S transfer
tubehave been washed out, you must thoroughly rinse down all
other parts of the machine that have come into contact with con
crete. Concrete that is not washed off immediately can attack the
paint, especially if aggressive concrete additives have been used.
Caution
The delivery line, water box, water tank and water pump must be
drained fully if there is a risk of freezing. The water box must also be
drained at normal temperatures during longer breaks in pumping,
e.g. overnight and at weekends.
Leave the water outlet open afterwards.
Danger of explosion
Atomized preserving agents are highly explosive. Keep away from all
sources of ignition whilst spraying.
Danger of poisoning
Cleaning agents, solvents or preserving agents sprayed in air can
enter the lungs and trigger serious damage to health. You should,
therefore, always wear respiratory protection during this work.
