Now restart the cleaning procedure with the hoses connected to
the machine.
16.2 CLEANING WITH COMPRESSED AIR
You will need:
- A compressor
- A sponge of a size suited to the diameter of the hose
- A container to recover the sponge.
Connect the sponge recovery container (Fig. 23 Ref. 2) to the
outlet of the hose using the Victaulic fitting. Insert the sponge at
the hose inlet (wet and of a suitable diameter) (Fig. 25 Ref. 1) and
connect the provided cleaning device with ball valve (Fig. 25 Ref.
2), making sure it is correctly locked.
Warning!
The sponge may be expelled violently from the end of
the hose: lay out the terminal hose correctly; if the hose is
blocked, the sponge will not be expelled. Switch off the air
supply by pulling the lever (Fig. 25 Ref. 2).
Before opening a material delivery hose coupling, make
sure the safety lever is open, the pressure gauge (Fig. 19 Ref.
9) reads zero bar and there is no residual pressure in the
hoses.
The operator must be specially instructed to do this job;
in particular, before opening a coupling, he must check for
residual pressure in the hoses and make sure that no-one
is in the vicinity. This hazardous operation must always be
supervised by an expert operator and done with the utmost
caution.
During cleaning, do not allow anyone to loiter, for any reason
whatsoever, in the vicinity of the terminal hose.
16.3 SUCTION CLEANING
If pumping is vertical, the sponge can be inserted at the end of the
terminal hose, and suction activated by turning the switch to the
left (Fig. 19 Ref. 7). The concrete will be drawn back into the tank.

Warning!
Every meter of D.50mm hose contains around 2 L of
material, while every metre of D.100 hose contains around 8 L
of material. If the hose is very long, the material may spill out
of the tank.
17. MAINTENANCE
Do not move the machine with the hopper raised or the
tank full of material
Maintenance must be performed by expert personnel,
after switching the machine off.
If the pump stops due to a fault during operation, clean the ma-
chine and pipelines immediately.
Make sure there are no oil leaks from the hydraulic system, engine
or the compressor during the stop. In case of doubt, check the oil
levels with the machine perfectly flat.
Perform the periodical maintenance operations specified in the
Diesel engine manual.
17.1 DAILY MAINTENANCE
Check that there is enough clean water in the tank (Fig. 18 Ref. 4)
and top it up if necessary.
If it is dirty or dense, concrete liquid has infiltrated from the pistons
and pumping pipe; if this is the case, replace the pistons.
To drain the tank, pull the evacuation lever; then close it again and
fill it up with water to the rim.
Replace the lubricating water at least once a week.
In cold conditions, empty the tank out at the end of the shift and
use antifreeze liquid.
Every day, at the end of work and with the machine running,
grease the affected points with the greasers located at (Fig. 19
Ref. 11) . A grease pump is supplied with the machine for that
purpose.
The operation is complete when grease comes out of the shaft
gaskets and couplings.
Do not apply more grease, so as not to pollute the material to be
pumped at the start of work.
Every day, check correct operation of the safety devices, and in
particular the grill safeties (Fig. 18, Ref.2), and the emergency
pushbutton. Top-up the fuel tank at the end of work. Check the
engine oil level and the Diesel fuel tank level before starting work.
At the start of work, make sure there were no oil leaks from the hy-
draulic system, engine or the compressor during the stop. Check
the oil levels with the machine perfectly flat.
17.2 WEEKLY MAINTENANCE
Every week a specialised person must grease all the necessary
points on the machine and also perform a general machine check.
In particular, make sure:
- the mixer shaft and S valve seals are in good condition;
- the S valve is clean and not worn;
- the air filter is clean; replace it if necessary;
- the engine and hydraulic system radiators are clean;
- the battery is charged, the level and specific gravity of the electro-
lyte are correct;
