Several basic concepts are given below regarding the
preparation of traditional mixes that may be conveyed with
POLI T:
• the aggregates must be within the granulometry
curve:
for example, use aggregates that have
particle size: 1/3 between 0 and 1 mm inclusive
1/3 between 1 and 3 mm inclusive
1/3 between 3 and 5 mm inclusive.
• for a batch of 140 litres, 50 kg (one bag) of
cement or plasticized lime are normally used.
• the water/cement ratio should be approx. 0.6:
i.e. 25 - 35 litres of water for a batch of 140 litres,
depending on the quantity of cement and the
moisture content of the aggregates.
• when using ready-mix mortars (mortars with
controlled shrinkage, normal or light cement-
based ready mixes), the instructions provided
by the producer of the material must be carefully
followed, in particular with regard to the quantity
of water and the mixing time.
POLI T basically consists of a hopper with built-in agitator,
which receives the mixed material, and a screw pump for
pumping the material. It may be fitted with a pan mixer
(/MP version) for preparing the mix.
The mix is unloaded into the hopper then pumped by
the screw pump to the place of application; the material
is conveyed through a hose to the spray gun (which may
differ according to the types of materials used), where air
coming from the auxiliary compressor is introduced to
propel the mix.
Pump output may be adjusted by means of a regulating
handwheel (13).
The output should only be adjusted with the motor
running, otherwise the variable-speed drive could
be broken.
The nozzleman starts and stops
the machine by opening and closing
the air control valve (14)
located on the gun,
or through a remote control
via cable (15).
A water gauge may be installed for batching the water
and a vibrating sieve for sieving the material.

Choice of pump
Three different types of pumps are available, each one
particularly indicated for a certain type of material:
STANDARD CONFIGURATION:
• Pump 2L6 (screw code 250.123, stator code 263.184)
for ready-mixed materials with particle size 4 ÷ 6 mm
(grit);
• Pump T25 (screw code 250.089, stator code 238.030)
for traditional mortars with particle size 8 ÷ 10 mm.
OPTIONAL:
• Pump 60.12 (screw code 250.136, stator code 263.366)
for self-levelling screeds.
Choice of spray gun
The specific gun is used according to the material:
• Gun (code 216.246) for traditional and controlled-
shrinkage mortars (accessory box code 201.112).
• Gun (code 216.252) for ready-mixed plasters and
structural mortars (accessory box code 201.067).
• Gun (code 216.266) for skim coats, plastics,

Electrical connection
Connect the machine to the site switchboard using a
neoprene (wearproof rubber) cable marked H07 RN-F and
having a minimum section:
4 x 4 mm for distances up to 20 m
4 x 6 mm for distances up to 50 m
4 x 10 mm for distances up to 100 m.
Using an electric cable with an unsuitable section
jeopardises machine operation.
The site switchboard should have:
• a minimum power of 12 kVA
• adequate earthing
• 35 A fuses (type Am)
• high-sensitivity differentials (30 mA)
• and in any case be in compliance with current regulations
in the country where the machine is being used.
Connect the earth terminal of the machine to the site
switchboard earth stake by means of a cable having a
minimum section that is never less than 16 mm².
If the machine is powered through a generating set,
use a 30 kVA set.
4.3 - PRELIMINARY OPERATIONS
Machine position
Place the machine as level as possible: the maximum
allowed gradient is 5° both lengthwise and crosswise.
The machine should be positioned on site where the radius
of action of the hoses may be best exploited.
Wedge the wheels.
Prepare all the material for cleaning the machine (water
hose, washing sponges, etc.)
Leave at least 80 cm free space all round the
machine and ensure that the ground in the working
area has no holes or hazardous protuberances.

12
13
Couplings
Check that the couplings are clean and in good working
order.
• Cam-lock couplings
When connecting the hose parts, check that the rubber
gasket (16) is present,
fully close the levers.
Hoses Ø 35 x 49 - length 10 or 20 metres
for maximum pumpable particle size of 0 ÷ 10 mm.
16
Hoses
Lay out the hoses, limiting their length as much as possible
(to reduce wear), at the same time checking that they are
in good condition.
During pumping the first 10 m of hose swing back and
forth a few centimetres: it is best to keep this section of
hose raised from the ground and in any case do not let it
rest on sharp edges or abrasive elements to prevent early
wear of the actual hoses.
Only use original hoses and couplings.
The hoses should be fitted by TURBOSOL
PRODUZIONE S.p.A. or by firms expressly
authorised by the same.
Under no circumstances shall TURBOSOL
PRODUZIONE S.p.A. be liable for injury to persons
or damage to property if other than original hoses or
couplings have been used.
Hose anchorage
The hose line should be suitably anchored: use the
provided hose safety straps for anchoring the vertical
sections and if necessary the special hose support upon
arrival at the oor level (optional - code 234.049 + 266.148
+ 266.103 / two pieces).

14
15
Connections
Connect the compressor air supply hose (17) to the
machine air supply hose (18).
Carry out the electrical connections of the compressor to
the machine switchboard (19).
Connect the material hose (20) to the screw pump and the
air hose to the machine air unit outlet connection (21).
Then connect the spray gun to the end of the material
hose; when using the gun for traditional mortars (code
216.246), remove the gasket to be
found inside the coupling
lock the joint levers
by means of the relative safety
spring (22), and connect the air hose,
fully tightening the couplings.
In the version with pan mixer (/MP), connect the socket to
the machine switchboard (23).
In the version with vibrating sieve, connect the socket to
the machine switchboard (24).

• Check that all the service valves (28) are closed.
Upon completion of any repair or maintenance
work, ensure that all the protective devices (fan
casing, hopper grid and mixer grid) have been
replaced and that no tool has been left inside the
hopper or the mixer.
Make sure that the protective grids are on the mixer
and the hopper and are properly xed.
Before starting the machine, ensure that only
authorised persons are in the vicinity, that is, at less
than 1 metre from the machine.
4.4 - STARTING
PREVENTIVE CHECKS
Carry out the following checks:
• Reduction gear oil level:
Check the lubricant
level (25).
If necessary top up with:
SHELL OMALA 220.
• Variable-speed drive oil level:
Check the lubricant level (26).
If necessary top up (27) with:
SHELL A.T.F. DEXTRON III.

- Start the mortar pump by pressing the relative start/
stop button I/0 (32).
- Read the pumping pressure shown on the pressure
gauge installed on the mortar delivery header (33).
The values should be approximately those given in
the table.
- After a few seconds (approx. 10 seconds), stop the
pump: the pump holding pressure can be read on the
pressure gauge and should be equivalent to approx.
half the pumping pressure measured previously.
• Calibrating the pump
If a new pump has been installed and in any case every
day prior to commencing work with the material, it is
advisable to check pump calibration as follows:
- Mount the pump
calibrating unit
(29), with the
shutoff valve
open.
- Fill the hopper with
water.
- Open the air control valve (14)
located on the gun and the air
supply valve (30) to be found
on the machine.
- Close the shutoff valve (31) of the pump calibrating
unit.

* pumps 2L6 and 60.12 calibration values.
** pump T25 pumping pressure value.
If the measured calibration pressure values are different
from the correct ones given in the table, use the bolts on
the pump clamp (34) to adjust as follows
- tighten: the calibration pressure increases
- loosen: the calibration pressure decreases.
Repeat the calibration operation until the correct pressure
values are obtained.
Now remove the pump calibrating unit (29) and connect
the material delivery hose.
Should it prove impossible to calibrate the pump unit, the
stator and if necessary the screw must be replaced.

Starting
Close the air supply valve (30) located on the machine and
open the air control valve
on the gun (14).
Fill the hopper with water to prevent the screw from
working dry.
Put the on/off switch (35) to the position I and the reversing
gear (36) to position 1 or 2.
The white indicator light (37) indicating power comes on.
Start the mortar pump by pressing the start/stop button
I/0 (32).
The pump starts
to turn; check the
correct direction
of rotation of the
screw (38) and if
necessary invert
the position of the
reversing gear (36).
The red indicator light (39) comes on when the
hopper safety grid is open. The agitator stops when
the red indicator light is on.
The red indicator light also comes on should the
overload cutout trip.
Check that the safety grid is in proper working order: upon
lifting it, pumping stops and the red indicator light (39) on
the switchboard comes on.
To start the machine again, press the start/stop button
(32). With the mortar pump in operation, adjust the pump
output.
The output may only be adjusted with the
pump in operation, otherwise the variable-
speed drive could be seriously damaged.
When reversing the pump direction of rotation
due to plugging of the hoses, first stop the pan
mixer (/MP version).
Start the compressor by pressing
the green button (40) located on
the pressure switch.

Pan mixer control (/MP version)
In the version with pan mixer, start the mixer and load the
materials.
Put the on/off switch (41)
to position I and then the
reversing gear (42) to
position 1 or 2.
The correct direction of
rotation of the mixer shaft
is shown in the figure
(43).
With the mixer in operation, check that the safety
microswitch is working properly: upon lifting the
grid, the mixer shaft should stop. To start the mixer
again, first put the on/off switch (41) to position 0
and then to position 1.
In the version with vibrating sieve, activate the electric
vibrator by putting the selector (44) to the position ON.
Check that the protective grids on the mixer and
the hopper are in proper working order: it should be
impossible to raise them more than 30 mm without
the mixer and the agitator stopping.
During these tests, check that there is always water
in the hopper: the screw must never turn without
water, otherwise it deteriorates very fast.
Use nitrile gloves to protect against cuts and
scratches; preferably use models with CE 940072
certication.

Conveying and spraying the mix
Drain the residual water of the pump calibration operation
from the hopper by opening the hatch located on the
bottom of the hopper.
Use nitrile gloves to protect against cuts and
scratches; preferably use models with CE 940072
certification.
During work use goggles, preferably with shockproof
polycarbonate lens, to protect the eyes.
Pour two or three bucketfuls (30 l) of slurry (50% water,
50% cement or lime) into the hopper.
If there is no slurry available but only ready-mix
materials, make them slightly more fluid than
normal.
• Open the air supply valve (30) located
on the machine and the air control
valve (14) on the mortar gun.
Preparing the batch
The mix should be plastic and within the grading
curve, as shown in point 4.2.
The pan mixer (/MP version) may be used to prepare the
batch.
When preparing mixes for traditional plasters, pour water
into the mixer; add 50% of the aggregate (sand), then
100% of the binder (cement) and lastly the remaining 50%
of the aggregate; add more water if necessary.
With traditional mortars it is advisable to use the vibrating
sieve to prevent the pump from being damaged by stones
or encrustation of material.
When preparing ready-mixed batches, follow the material
supplier’s instructions.
For correct batching of the water, a water gauge is
available (optional), which indicates the quantity of water
put into the mixer.
• Turn the water gauge so that the indicator is on position
0.
• Put water into the mixer, turning the lever in the direction
indicated in the drawing.
• Close the valve, by positioning the lever at right angles
to the actual valve, when the litre-counter indicator has
reached the required quantity.
Prior to each new batch, put the water gauge indicator
to 0 to facilitate operations.
