•
Close the cleaning valve and fill the hopper with water.
•
Switch the pump on again, in
“Suck” mode. Push the
material in the conveying pipework forwards to the
discharge.
If a single filling of the hopper is insufficient for a long
pipe run, switch the pump off before air is drawn in,
and fill the hopper again with water. Then continue with
the discharge of the material until the cleaning sponges
emerge from the discharge hose.
•
Take care that the water flowing from the discharge hose
does not flow into the formwork.
•
Suck the water back into the hopper by reversing the
pump.
•
If the protective grill has a safety cut-out, agitator and S-valve come to a halt as soon as the protective grill is
opened. When cleaning, briefly shut the protective grill, let the pump run through one cycle, open the protective
grill again. A protective grill that is bolted in position remains in position throughout cleaning.
•
Remove the remaining water by opening the cleaning valve. Carefully spray the S-valve, hopper, conveying
cylinder and wash-out tank until they are clean.
•
Clean the rest of the machine also, and spray it with formwork release oil.
See further information in the separate documentation supplied by the manufacturer.
NOTE:
If there is a risk of frost, drain the wash-out tank, water tank and water
pump. The wash-out tank should also be drained at normal temperatures
during long pauses in pumping, overnight and at weekends.
