of people because of mechanical reasons.
ATTENTION! : This symbol means that a direct danger exists for life and health of
people because of electric power.
2.2 Obligations
The manual of instructions always has to be kept near the machine and also it is important to have the
local regulations about the prevention of accidents and the protection of the environment handy. These
documents always have to be taken into account.
In addition to it, it will also be necessary to have the domestic regulation for the country in which the
machine will be used.
The V2 must only be used:
• For the use according to the established
• In a perfect and secure technical state
The damages that can affect the security have to be eliminated immediately.
The V2 is a machine which has been certified for road transport, that is why it is subjected to the
currently effective traffic norms. That bears the obligation of taking an official registration and the
obligation of carrying out an inspection according to the effective legislation.
2.3 Warranty and responsibility
Please take into account the "General conditions of sale and delivery". These conditions are available
for you after conclusion of the contract. In the event of damages to people or materials, demands that
are derived of the guarantee or responsibility will be excluded if these damages can be attributed to the
following causes:
• an inadequate use of the machine
• inappropriate assembly, operation, handling or maintenance of the machine.
• not taking in consideration the indications of the manual of instructions about the transport,

3 Safety
3.1 Safety Systems
Before starting the machine, all the protection devices have to be placed and they have to be prepared
to work correctly.
The machine V2 full fills all the requirements of the European Safety Regulations for
construction machines, for this reason the machine has two safety systems: one opening the grill and
the other when taking out the grill from the hopper.
The mixer has an incorporated safety system that in the moment of emptying the
mixer in order to put the material inside the hopper, the mixer paddles stop immediately. This safety
system has to be checked and always be under perfect operating conditions.
The hopper is protected by a grill which avoids entering any part of the human body.
In case that the grill is removed, there is a safety system that stops the pump motor immediately.
Do not try to get passed the safety grill!

Rendering Machine V2______________________________________________________________________________________ 11
3.2 Safety measures according to indication
The manual of instructions has to be kept near the machine. Also, besides the manual of instructions,
local regulations on the prevention of accidents and the protection of the environment have to be
available and taken into account.
All the safety and danger indications placed in the machine have to be kept in readable state, and
when necessary, renovate them.
3.3 Safety measures in the operation
Please, start the machine only if all the protection devices work completely; make sure of it before
plugging it, since no person should be in danger.
Check at least once a day if in the machine there is some external damage and if the protection devices
work perfectly.
3.4 Revision and maintenance
• Carry out the adjusting, maintenance and inspection within the time established. The flexible rubber
tubes with their couplings are subjected to a natural wear process for close contact and aging. It is
recommended that the machine is checked by a specialist (at least every 3 months) keep the machine in
good shape. Write down the revisions in checking list included in the attachment.
• Disconnect the machine in all the maintenance works, inspections and repairs carried out and make
sure that the machine doesn't start up involuntarily.
• Place a warning note so that an involuntary connection doesn't take place.
• Make sure that all the screws are fixed correctly. Check the correct operation of the safety devices
after the maintenance works are done.
3.5 Mechanical changes in the machine
DO NOT carry out without previous authorization of the manufacturer any installation change or
alterations in the machine. All the alterations need an authorization in writing of the company Utiform
Technologies, S.L.
All parts that are not in perfect state should be changed immediately. Use only original spare and wear
parts. In the case of use of non original parts, the company UTIFORM does not guarantee that these
components are fabricated in a resistant and secure way.
3.6 Cleaning of the machine
Keep the machine clean. Use an ecological machine protector. Use and evacuate the substances and
used materials, mainly:
• in works carried out with oiling systems and hydraulic facilities and
• in the cleaning with solvents.

Rendering Machine V2______________________________________________________________________________________ 12
4 Starting it up
4.1 Preparation for the starting up
4.1.1 Safety indications
• Place the machine in such a way that is in working in a secure place and protected
from the unexpected fall of objects.
• Get the machine in a safe position using the tire stabilizers or the support leg of the machine
• Check all the safety systems before beginning to work.
• Place transport hoses tracing a road the shortest possible. For the direction changes make a generous
radius (approx. 40 cm) to avoid that the hoses bend. The least couplings you use, the better.
• When working with scaffolds or higher levels, the hoses must be held conveniently and without
bending using hose belts according to the security rules.
• Assure all couplings of the connected hoses to avoid their opening up.
•Control the hoses and couplings regularly against wear (abrasion and aging).
4.1.2 Locating the machine
The surface has to be as flat and firm as possible. In case of a loose or wet surface, use wooden bars,
to avoid the supports from sinking into the surface.
ATTENTION! In order to avoid damages, please note that the oblique position of the
machine should not surpass 10º longitudinal and 20º traversal.
4.1.3 Material hose
Connect the hose to the material exit of the machine and take it through the shortest way to the
working place. The shortest it is the conduit, there will be less energy consumption and therefore there
will be less failures. Do not close the hose couplings without cleaning them; do not forget the rubber
joints in this couplings: dirty couplings are not tight and they produce jams.
Connect the material outlet well to the chassis because when pumping, there is a notable increase of
weight and torque. Put the machine as horizontal as possible to avoid blowouts and jams while
pumping material.
Check the fastening of the couplings if necessary , to prevent a detachment.
Only use original UTIFORM or other authorized material hoses and couplings.
For the Rendering Machine V2 it is recommended to use material hoses with a nominal interior
diameter of 50 mm with 40 bar pressure, at least in the initial hose, being able to reduce this diameter
according to the specific working conditions of each moment.
With this kind of reduction you can produce a decrease in the performance of the machine’s pump and
mainly, something to keep in mind is the acceleration of the wear process of materials that are
subjected to the material flow.
The hoses and the couplings are subjected to a natural wear for close contact and aging.
Let a specialist check that the hoses and couplings are in good shape, minimum every three months
(safety control check list).

Rendering Machine V2______________________________________________________________________________________ 13
4.1.4 Air hose
The air hose is connected between the air outlet and the spray gun. In the spray gun the product hose
and the air hose join.
4.1.5 Control of levels
Before setting the machine on, make sure that there is enough fuel in the deposit.
One of the most important functions before the daily starting up of the machine is
to control the level of motor oil , the compressor and the hydraulic circuit’s oil, having the required
levels in each one of the elements.
4.2 Starting up of the machine
4.2.1 Safety Indications
• Do not place the machine in closed places, since the intoxication danger exists due to the
escape of gases!
• Eliminate immediately all the machine damages that can affect your safety.
• Some materials could also put health in danger, for that reason, always wear the necessary
gear advised by the manufacturer (breathing protection, gloves, etc.)
• Keep in mind the norms of professional associations, mainly the norms of
prevention of accidents in the construction branch.
• Elaborate and transport only suitable materials for the machine (see annex: correct use).
For any questions contact the official technical service at UTIFORM.

Rendering Machine V2______________________________________________________________________________________ 14
4.2.2 Safety indications - operation
•Keep the hood of the machine closed during the operation!
• Start up the machine only when all the protection devices are working perfectly.
• Before connecting the machine make sure that nobody can be in danger for the setting up.
• Check the machine at least once in each shift to see if there were external damages, and make sure
that safety appliances work correctly!
• Protection grill:
The mixer deposit is closed with a safety grill equipped with a safety switch that causes the immediate
stop of the motor in the event of unexpected opening of the grill.
This protection grill can only be opened up if the safety switches react. The grill needs a special tool
to disassemble it since it is installed mechanically. In this way it is guaranteed that it cannot occur any
danger of injuries.
Work only with the protector grills installed!
Always use safety appliances appropriately, do not try to manipulate the safety switches!
• Prevent damages.
In the case of damage, suspend all the works, since a breakdown could be caused on the
machine!
4.2.3 Starting up the motor
In the machine V2 the revolutions of diesel motors come adjusted from factory, so it is not
necessary their variation in the construction sites.
In diesel engines with electric starting motors, warm up well before starting. To continue this process
correctly, it is necessary to visualize the “power off” of the led of the
resistance placed in the electric control panel of the machine. In any case, it is convenient to leave the
diesel motor warming up a little, before proceeding to its routine operation.
You will be able to see more details in the enclosed instructions of service for
the Diesel motor.
In case of electric model, it is important to have enough power. The necessary tension for the operation
of the machine in the electric version is 400 V with a32 A automatic switch. The motor protection is
incorporated in the switch of the machine.
The cable section recommended is 5 x 2,5 mm2. In case of very long distances between the machine
and the electric power source it is recommended a 5 x 4 mm2 cable.
Before beginning to mix and spray, it is necessary to close the hood of the machine to avoid
dirt in its interior parts. This way, the air aspired by the motor and the compressor will be
the less powdery possible.

Rendering Machine V2______________________________________________________________________________________ 15
4.2.4 Mixture preparation and pumping
Check that the mixer is fixed correctly. Fill up the mixer with material according to the
necessities or according to the manufacturer’s advice.
Connect the mixer with the control switch.
Before beginning with the pumping you should fill the hopper first with some 10-20 l of water cement
mix to avoid unexpected jams inside the hoses.
Next, you can start the pumping; in order to do this, you should connect the pump using the switch in
the electric box. When there is no water cement mix left in the hopper, it will be filled with the blended
material coming from the mixer.
The mixer’s turn speed as well as pumping are adjustable using the assigned flow regulators; they
located in the inferior part of the control box.
To get a proper mix, the pumping revolutions “speed” can be adjusted at any moment by the operator.
Important Warning!
Feed the hopper continuously and let the machine work.
Never let the machine work with the hopper full with material during long periods! This
would cause the sedimentation of the materials and the possibility that the pump would jam.
Never let the pump work dry, it would produce waste and damage of the rotor or stator.
4.2.5 Mortar spraying
In the spray gun’s air entrance you will find a spherical key which regulates
the quantity of air.
The spraying quality can be adjusted in order to have a closer or open flow, only by regulating the
position of the spray nozzle.
When opening the air valve in the spray gun, the air begins to come out from the nozzle; at this time,
the pump begins to pump material through the hose. First, the water cement mix comes out and is
pumped into a bucket until the mortar starts to come; as soon as the mortar begins to come out through
the spray gun, the spraying can begin.
The spraying gun should always be taken with slow movements the closest possible to the wall, a
normal distance is approx. 20 cm.
Try to direct the mortar flow slightly up. If the handling is correct, there will be no waste of material.
4.2.6 Start and stop of the machine
Start and stop of the machine can be carried out in two different ways, according to the remote control
used:
a) Pneumatic remote control.
In this case, the control can be carried out from the spray gun. You need a belt driven compressor in
the machine.
Connect an end of the air hose of 1/2" (article number 38051 to 38053) to the machine’s air exit,
prepared in the front part, spreading it without any bending along the mortar hose. Connect the
spraying gun with the other end free of the air hose and with the mortar hose and close the air switch.

Rendering Machine V2______________________________________________________________________________________ 16
When closing this switch, pressure builds up in the air hose and carries out the stop function on the
pumping motor.
b) Radio remote control.
This system is optional. This system is made up of a sender which you can find inside the electric box,
a manual receiver that will be manipulated by the operator, an antenna located in on the top of the
hood and which should be free of obstacles and a battery loader to connect to the conventional electric
supply.
The operation of this system is as simple as an on and off located in the mobile originator manipulated
by the operator. In order to make this system operative in the machine, it is necessary to previously
place the selector located in the frontal of the electric box in the “manual” position, making it possible
to manipulate the machine both by remote control (radio frequency) as well as directly from the
electric box.
When pressing the green on-button a led lights in the originator and in this moment the machine will
start working.
In case that the machine stops suddenly it can be due to a sign loss between the originator and the
receiver, so it will be necessary to begin the operation again.
The control remote works with a battery saving system, so that when it stops sending signals, after a
while the position led “0-stop” of the originator stops blinking and goes to the on-hold status, which is
battery saving.
The battery located inside the originator for its protection has a capacity or enough autonomy for a
whole day of work.
We recommend to charge the originator after the end of each day of work, so that it is ready for the
following day. This process is as simple as connecting the charger to a voltage of 220 V. single-phase
and the other side to the inferior part of the originator, which is there for this purpose.
4.2.7 Finishing the work
• After the last material load, pump until the hopper is empty and the pumping shaft is completely
visible.
• Take out the pressure in the hose, making the transport shaft go for a few seconds to the back. The
inversion of the pumping direction is possible when rotating the electric selector located in the control
panel.
• Disconnect the mortar hoses. The operator should prevent accidents and wear protective gear
(glasses) while disconnecting the hose couplings.
• Empty the deposit letting the remaining material flow through the cleaning opening in the inferior
part of the hopper . Let the material flow in an appropriate recipient to avoid pollution and close the
opening again. The opening closes with a rubber ball and a screw.
• Wash the exterior of the machine completely with clean water and a brush.
• Clean the mixer with a brush and water.
• Fill the hopper with clean water, start the pump again and let it work until
the pump transports only clean water.
• Let approximately half meter of material out of the hose, then put in one or two rubber balls.
• Connect again the mortar hose to the machine and start the pump until the hopper is empty. Continue
with the cleaning until you see only clean water coming out of the hose, if it is necessary add more
water to the hopper.

Rendering Machine V2______________________________________________________________________________________ 17
• Clean mainly the hose couplings and rubber joints!
• Then, it is necessary to clean the spraying gun very well, blowing especially the
air nozzle and the air valve.
• To keep the machine in good condition, spray it daily with fuel and oil, this way the mortar will stick
less and it will be easier to clean it.
• As for the conservation of the transport shaft, spray the screw with a special fluid (Article number
41061288), from the hopper toward the opening of the screw. To apply it easily, start the pump for a
while.
5 Faults and corrections
Jams are the most common problem in the transport of material. A jam is when a material ball has
been formed in the transport shaft or inside the hose. In both cases, it is necessary to open up and clean
the blocked connection.
!Wear protective glasses!
!Control in the pressure manometer so that the conduction is free of pressure. The
manometer has to indicate a pressure of 0 bar!
!Keep in mind the possible material splashes.
!The couplings that have to be unfastened and should be covered with an empty sack or
something similar.
!Wear protective clothes!
!Make sure that there is no people in the danger area!
Blockage can be formed for three reasons:
1. It is not possible to pump the mixture of the material, because it is too liquid or
too thick.
2. The mixture has been too long in the hopper and the flow of water in the interior of
the hose produces that the thick material has gotten stuck.
3. The hose is not sufficiently greased, that is to say, is has not been pumped previously, it is damaged
or bent abruptly.
5.1 Jams in the pump
1. There is no material being transported.
2. The manometer (if there is any) in the end of the pump does not show any pressure.
Proceed in the following way:
• Let the transport shaft work backwards for a little while to lessen the pressure in the flow of material.
• Disconnect the motor.
• Unhook the hose of the machine.
• Remove the cone of material from the machine.
• Remove the compressed material of the cone and, if it is possible, of the pump.
• Clean the pump carefully.
• Start the motor.
• Let the pump work shortly.
• Change the turning direction several times.

Rendering Machine V2______________________________________________________________________________________ 18
5.2 Blockage in the mortar hose:
1. No material is being transported.
2. The manometer (if there is any) in the end of the pump doesn't show any pressure.
3. The manometer in the end of the pump (if there is any) indicates the maximum pressure.
Proceed in the following way:
• Allow the transport shaft work backwards for a while to lessen the pressure in the material release.
• Stop the transport shaft.
• Disconnect the motor.
• Unhook the transport hose.
• Introduce a water hose in the transport hose and rinse it well; at the same time hit the hose part by
part to locate the jam. Clean the hose this way and in all its longitude and allow all the water to come
out.
• Connect the hoses again and connect them to the machine.
• Pump water and cement mix first through the clean hose.
• Fill up the mix deposit again and continue working.
5.3 Failures in the machine
If the diesel motor stops working it is due to the following failures, which are identified by the control
lights in the machine’s panel:
- Oil pressure: oil pressure is too low.
- Oil ‘s temperature: motor temperature too high.
- Temperature of water in radiator: motor temperature too high.
It is necessary to eliminate the failure immediately.
In the control panel of the machine you will find another series of warning lights, but they don't cause
the emergency stop of the diesel motor:
- Air filter: Accumulated dirt in the air filter.
5.4 Advice for working in winter
If there are difficulties to work because of low temperatures, it is a good chance to take the machine
for maintenance and repairs. Make the annual revision in an authorized shop.
• Up to 0 ºC it is guaranteed an operation of the machine without difficulties. If the
temperature reaches below the freezing point, keep in mind the following:
• Prepare the working place and the material in an appropriate way.
• Do not use frozen material.
• Use only as fuel diesel suitable for winter! Due to special preservatives this diesel stays fluid in low
temperatures. The diesel fuel used in summer freezes under low temperatures and blocks the
conductions.
• Use motor oil whose viscosity responds to the external temperature.
• If the temperatures are extreme, it is recommended to disassemble the battery at night and keep it in a
warm place. Install the battery again little before the starting of the machine.
• For the non maintenance-free batteries, keep in mind the correct acid level
(10 to 15 mm above the upper edge of the plate) and the appropriate density!
