ANY TOTAL OR PARTIAL REPRODUCTION IS STRICTLY FORBIDDEN
Before the slurry ends, pour the mixture onto the vibrating sieve by opening the discharge hatch using the relevant lever
(FIG.38-REF.1).
Activate the motor taking the master switch (FIG.32-REF.2) into position "I", the machine starts to pump.
The slurry starts to escape from the gun and when it has finished, the mixture to add on the work site.
Now the machine is operational and can be stopped by acting on the air cock positioned on the gun (FIG.35-REF.3).
Normally, when the machine stops the operator must take the by-pass lever to the recirculation position (vertical). At the next
start-up take the lever back to the pumping position (horizontal).

FIG.37 FIG.38
In the case of extended shutdowns, open the bleed cock (FIG.35-REF.2) and position the by-pass lever vertically in a way that
the material is recirculated in the hopper.
Check that the level of mortar in the hopper is always such to cover the mixing device. On the contrary, the pumping piston
(rubber) deteriorates rapidly due to the lack of lubrication.
The gun operator must never aim the jet towards other persons.
During the pumping phase, the operator at the machine must check that the PRESSURE manometer (FIG.37-REF.1)
(positioned on the top of the pup unit) never exceeds 20 ÷ 25 bar.
A higher pressure indicates a blockage in the material piping or in the gun. If this occurs, stop the machine and discharge the
pressure in the pipes taking the by-pass lever (FIG.37-REF.2) to the vertical position and then remove the blockage (see chap.
10.1).
If the gun should block, for no reason must you look into the hole of the gun deflector. The unexpected escape of
the blocked part or pressurised mortar could cause dangerous accidents to the eyes.
During all operations, the air cocks must be completely open or completely closed. Partial opening causes
machine shutdown.
In the case of overloads die to pumping pressures that are too high, the safety device intervenes that is positioned inside the
reducer.
