The T7 ismade up primarily of a hopper with built-
in agitator that receives the mixed material and of a
worm gear pump for conveying that mix to the point of
application. It sprays it on the walls bymeans of a spray
gun (which may differ in nature depending on the type of
material employed). There the mixture combines with air
from an auxiliary compressor.
The pump output is controlled through the two buttons
for the output (9) and (10) which are placed on the control
panel; the output is shown on the display (11).
Turning on and off of the machine is controlled directly by
the spray gun operator through the electric
remote control (12).
Upon request the electric remote control box can be
equipped with output regulation (optional extra): with the
push-button (13) you increase and with the
push-button (14) you decrease
the output.
With the push-button
(15) you start
and stop the
machine.
The machine can be only handly transported.

4.2 - PUMPABLE MATERIALS - APPLICATIONS 4.2.1 - CONVERSION KIT into admixture dosing pump
To pump silicate with T7 in conjunction with other machines
such as the POLI T, the PRO H, the TSB 215.
Silicate irritates the eyes and the skin. Use
appropriate protection equipment for your hands
and wear a mask to protect your face.
Handle, in any case, these materials with the
greatest care and stick to the instructions provided
by their manufacturer.
To use the conversion kit into admixture dosing pump itis
necessary to remove the hopper with its cover safety grill
and lifting handles too.
Remove the hopper
by unscrewing
the 4 fixing screws (16).
Secure the silicate cover (17) complete with couplings to
the pump body.
Remove the gauge (18)
fitted onto the delivery
flange.
Connect the pressure

12
Positioning the Machine
Place the machine in the most horizontal possible position:
the maximum gradient allowed is 5° both lengthwise and
sidewise.
The machine must be set on the jobsite as close as
possible from the place of application.
Prepare the necessary material for cleaning the machine
(water hose, washing sponges, a.s.o.)
Leave at least 80 cm. of clear space around the
machine and set up a working area free of holes
and dangerously protruding edges..
Electrical connection
Connect the machine to the site electric control panel
or a socket of 16 A bymeans of a neoprene cable
(scratch-resistantrubber)labelled HO7 RN-F and
havinga maximum section:
3 x 4 mm. for distances up to 35 m.
If a cable of inadequate section is used, the machine
does not work properly
The jobsite’s electrical system must have:
•a minimum operating power of 3,3 kW,
•be properly grounded,
•fuses of 16 A (type aM),
•highly sensitive differentials (of 30 mA),
•must meet all the regulations enforced
in the country where the machine is being used.
Connect the machine’s ground terminal to the earth
leakage device by means of a cable having a section equal
to the feeding cable and never lower to 16 mm2.
4.3 - FIRST OPERATIONS

13
Hoses
Lay the hoses down and at the same time check them to
make sure that they are in good conditions.
While pumping isin progress, the first 10 m. of hose will
swing back and forth several centimetres: itisbest to
keep that section of hose raised above the floor in order
to avoid having the hose rubbing on edges or abrasive
surfaces and to prevent fast wear and tear on the hoses
themselves.
Use only those hoses and coupling devices originally
supplied with the machine.
The hoses must be fitted by TURBOSOL
PRODUZIONE S.P.A. or by firms explicitly authorized
by TURBOSOL. In no case whatsoever shall
TURBOSOL PRODUZIONE S.P.A. be held liable for
injury or damage to persons or things resulting from
the use of non-original hoses or coupling devices.
Couplings
Check to be certain that the coupling devices are clean
and in good working order .
•Cam-lock couplings
When you connect the hoses, check that there is the
rubber ring (25),
lock the levers tightly.
Hoses Ø 25 x 37 – length of 15 meters
for a max. pumpable granulometry of 0 - 5 mm.
25

14
Connections
Connect the material hose (26) to the worm gear pump.
Connect the air hose to the auxiliary compressor (27) at
the spray gun.
Then connect the spray gun to the final part of the material
hose (28).
Connect the remote control cable to the machine
connector (29).
The vibrating sieve is not necessary when you use ready-
mixed materials.
The vibrating sieve is necessary with traditional materials
to avoid that aggregates, of non pumpable dimensions,
damage the stator.
Connect the plug of the vibrating sieve to the socket (30).
29
16
28

15
Various types of spray guns are available depending on the
material sprayed.
Each spray gun is made of:
a coupling to the material delivery hose (31),
a coupling to the air hose (32),
1 air control valve (33),
an air nozzle (34),
with or without possibility of regulation (35)
a deflector (36).
Generally speaking, with deflectors having a smaller
diameter the material is sprayed with a wider pattern and
vice-versa.

To start up the machine turn the main switch (39) (red on a
yellow background) clockwise to the I position.
Turn the selector start/stop/reverse (40) on position 1and
check that the machine is pumping normally andmodify
the output according to your necessity through the buttons
that set the output “plus” (41) and “less” (42).
Put the selector (43) on position 2and check that the
rotation direction reverses.
Check that the remote control works properly.
Turn the selector start/stop/reverse (39) and the remote
control selector (44) on position 1andby operating the
remote control, check that the machine starts and stops
normally.
The lamp (45) lights when the inverter interferes to protect
the motor against overload.
If the pilot light (46) is switched on, it shows that the
control panel is energized.
The line socket must always be disconnected when
you operate on the machine and above all on the
electric board.
Before starting the machine, pour some water in the
hopper to avoid that the worm gear runs dry .
Check that the protection grill is well mounted and
fixed on the hopper.
Before turning on the machine, be certain that no
one, except the operators, is standing too close to it.
Be careful: the machine must always run with
material or water in the hopper.
If this is not the case, the pump will wear out
quickly.
Working pressure is indicated by
the gauge (37) positioned in
the pumping group.
The “standard working
pressure” value depends on
the material and hoses used:
it isrecommendable to check
out systematically -on the mortar
hoses pressure gauge- the value indicated in order to
promptly find out any fault.
To ease this procedure, a pressure control device is
available (38) (optional extra) which must be coupled
directly to the gun.

If necessary, remove the protection grill (34) in the
hopper, to wash carefully, but before removing the grill,
disconnect the line socket (35) (with main switch on
position 0); then fixit once again correctly,reconnect
the line socket.
Put the cap on the hopper discharge collector and fill the
hopper with water.
Star the machine:
•main switch (39) and selector start/stop/reverse (43) on
position I
•pump water until clean water flows out of the pump.
•Reconnect the hose to the pump .
•Start the machine and pump water until the washing
sponge goes out.
Stop the machine by turning the selector (43) on position
0(stop) and turn the main switch (39) (red on yellow
background) on position 0.
After completing maintenance or repair work, make
sure that all the safety devices have been put back
in place and that no tools have been left inside the
canopy or the hopper.
Once you have pumped your last batch which should be
a little wetter than usual and you begin to see the bottom
of the agitator clearly, stop the pump byusing the selector
start/stop/reverse (43).
Turn the main switch (39) to the 0position.
•Remove the spray gun and wash it carefully, dismantling
the deflector at the same time (36).
•Check to be sure that the nozzle hole (34) is free (if
necessary, clean it ).
•Disconnect the hoses from the
mortar pump hoses and insert
one cleaning sponge into the
hose.
Remove
the discharge
collector cap (47)
on the hopper.
Wash carefully
the hopper with
a stream of water.
Do not direct the water jet onto the control panel or
towards the holes in the lower casing protecting the
electric motor, since it could cause damage to the
actual motor and the electrical equipment inside the
machine.

4.6 - PUMPING GROUP
Replacing the pumping group
Operate as follows:
Stop the pump, then turn off the motor by using the
main switch (39) before carrying out this operation.
•Raise the protection grill in the hopper;
•Remove the material delivery collector by unscrewing
the braces fixing bolts with the key included in the
equipment.
•Replace the pumping group.
Put the group stator-
worm in a vice, block
the stator, unscrew the rotor
and remove it;
Check to see if the worm
can still be used ( its
diameter must not be more
than 2 mm. smaller than its
original diameter). If this is
not the case, replace the
worm as well as the stator.
To assemble the unit, smear both the worm and the stator
with vaseline (under no circumstances should you use
oil or mineral grease! Such products could cause
irreparable damage to the stator). Then screw the
worm back into the stator. The stator must be mounted
with its countersunk side facing the hopper.
If this procedure makes the re-assembly difficult or even
impossible, pick up the unit with the worm partially inserted
and bang it on the floor several times.

19
Operations to be carried out every 6 months or
every 500 hours
Check:
•The seal of the hopper gaskets.
•The air and material hoses are in good working order.
Listed here below is the essential information
needed for proper maintenance of this machine.
The machine’s operator must read those data before
beginning to operate the machine.
Operations to be carried out daily
•Lubrication
Grease the agitator support in the hopper through the
specific greasing point (50).
In order for this operation to be carried out correctly, the
grease must flow in the hopper.
If you forget to perform this operation, the seals and
supports will be worn out in just a few days’ time.
Read also carefully the instructions booklets about
accessories as compressor, injection group
•Preventive care
Spray demoulding liquid on the hopper.
Check that the seal of the hopper gaskets is good.

6 - PROBLEMS – CAUSES – REMEDIES
6.1 - MORTAR IS NOT FLOWING OUT OF THE SPRAY GUN
The spray gun is blocked
A hardened crust of material, a pebble or a deflector
whose orifice is too small for the material being used may
cause a clogging-up in the spray gun:
•THE MATERIAL DOES NOT FLOW OUT OF THE SPRAY-GUN
In this case:
•Stop the machine by using the main switch.
•Release pressure in the delivery material hoses by turning
the pump reverse for a few seconds.
Release always pressure in the hoses by turning
the pump reverse for a few seconds (5-10) before
disconnecting them.
•Disassemble the deflector and, ifnecessary, the spray
gun so as to remove the cause for clogging.
•Before mounting the deflector and spray gun once again,
be certain that the nozzle is free (and, ifnecessary, clean
it with a piece of wire).
If the mortar is dripping from the spray gun during work,
try to replace the deflector and/or nozzle with one having
a smaller hole
•Start the machine once again and check that the material
flows out normally of the hoses.
Worn out stator
A worn out stator can prevent the material from flowing
out of the gun and mayeven cause blockage due to
overheated material at the beginning of the hose.
It isnecessary to replace the stator and remove the
clogging in case.
Lack of material in the hopper
If, during the work, mortar is flowing in a non-continuous
way, check, at first , that there is material in the hopper.
Mortar hose blocked
A faulty mix or an overly prolonged pause may cause a
clogging up of the material delivery hose:
•material is not flowing out from the spray-gun.
In this case:
•Stop the machine by using the main switch.
•Release pressure in the delivery material hoses by turning
the pump reverse for a few seconds.
Release always pressure in the hoses by turning
the pump reverse for a few seconds (5-10) before
disconnecting them.
Find out just where the mortar delivery line is blocked: the
hose will be hard and stiff at this point.
The worse points are near the couplings.
Disconnect the clogged hose,
hit it with a hammer at the
clogged point so as to break
up the “plug”, andlet the
hardened mix flow out.
•Turn the machine on for several seconds, andmake
certain that the hose has been freed of the “plug”:
the material will flow normally from the hose.
Pour some slurry into the hose before the point where the
blocking occurred (gun direction), connect the hose line
once again, and start over again.
Mortar hose bent
Same as for mortar hose blocking.
Find the bend and straighten the hose.
If the material inside the hopper is not pumpable,
empty the hopper by disconnecting the hose from
the pump and let the material flow out.
Remove, ifnecessary, the discharge cap of the hopper
and wash out all the material with a stream of water.
Prepare the right mix and start again.
