STARTING THE MACHINE
Before starting the machine, prepare the desired mixture in the site concrete mixer and separately prepare 15 ÷ 20 litres of
slurry (50% water + 50% cement or lime) and pour it into the hopper.
Check that the air flow cock (FIG.28-REF.1) is open, that the bleed cock is closed (FIG.28-REF.2) and that the air cock to the
gun (FIG.28-REF.3) is open.
Also check that the by-pass lever (FIG.29-REF.1) is in a vertical position (material recycle in hopper).
Attention: The machine must always function with material or water in the hopper.
If this is not the case the piston will deteriorate.
