The preferred methods for cleaning the delivery line are reverse
pumping or forced cleaning with water. The agitator must be switched
on during reverse pumping. Otherwise, the concrete flowing back into
the hopper can bend the agitator shaft. Use a catch basket, pipe
cleaning head and wash-out ball for forced cleaning to prevent any
water from flowing into the formwork.
Never spray remote controls or control cabinets with barrier agents
(mould oil or similar) to protect them against contamination. This cau‐
ses significant corrosion damage to the electrical system.
There is a risk of injury at all points on the machine from slipping, trip‐
ping, bumping into things, etc. Use the handles and steps to climb in‐
to and out of the machine. It is forbidden to stand on the grille. Do not
jump from the machine.
Do not reach into the hopper or any other moving machine compo‐
nents. This rule must also be followed when you are opening the out‐
let on the bottom of the hopper. Do not remove the grille.
Only point the water jet into the hopper or other moving machine
components. Do not insert the hose. It could become entangled with
moving machine components.
2.8.2 Cleaning agents
Take care when using aggressive cleaning agents. Aggressive clean‐
ing agents may attack materials (e.g. rubber) and painted surfaces.
You can use commercially available paint cleaning and care agents,
as long as these have a pH value of between 4 and 9. Ask the manu‐
facturer of the cleaning agent to confirm its suitability. Observe the
