2.4 Protective Devices
Prior to starting up the machine, all the safety devices must be prepared to function. The protective grills
are a fixed safety device and can never be removed while the machine is functioning. The HD-50/07 machine
fulfils all the requirements of European safety standards for construction machinery.
Never put your hand through
the safety grill !
2.5 Safety measures in normal operation
Only start the machine when all the protective devices are fully functioning. Ensure prior to connection
that no one is in any danger.
Check at least on a daily basis, the machine and all its accessories, such as the transport pipes, and the
automatic outlet tripod to ensure that there is no external damage and that the protective devices are in place.
Above all, check the transport pipes for breakages, dents or damage to the material.
Check for wear, correct functioning, breakages or possible indication of damage to the transport pipes,
or at least every 3 months all the transport pipes should be changed along with their couplings.
2.6 Service and maintenance, prevention of breakdowns
• Carry out any adjustments, required maintenance and inspection work within the specific term.
Flexible rubber pipes with their couplings are subject to natural wear, through rubbing and ageing. A
specialist should check (at least every 3 months) that they are in good condition and change them if
necessary. This process should be noted on the checklist provided for this purpose.
• In all maintenance, inspection and repair work, ensure that the machine is not connected to the
electrical power and in particular that it is not accidentally reconnected by pressing the connection
switch.
• Place a warning sign to prevent any accidental connection.
• Check helicoidal combinations released during adjustment. Check protective functions and
devices when maintenance work is complete.
2.7 Mechanical changes to the machine
DO NOT carry out, without the manufacturer’s prior authorization, any changes in the installation or
any alteration to the machine. This also applies to welding of supporting parts. All changes require the
manufacturer’s written authorization. All reforms require the written authorization of the manufacturer,
UTIFORM.
Any parts which are not in perfect condition should be changed immediately. Use only original spare
parts and wearing parts.
Using parts which are not original means that there is no guarantee that they have been built and
manufactured in a safe and resistant manner, and therefore the machine guarantee is from that moment invalid.

2.8 Cleaning the machine.
It is important to keep the machine free of encrusted dirt, and therefore biological machine conservation
liquid should be used to protect from corrosion and separation.
Under no circumstances should you use diesel fuel for cleaning and care of the machine, since it may
cause irreparable damage, above all to plastic seals and parts.
Use and remove the substances and materials used, in particular:
• in any work carried out in lubrication systems and devices and
• in cleaning with solvents.
2.9 Safety regulations for towed machines
General safety indications
1. The person who activates the machine is responsible for keeping it in a state of safe operation.
2. Use only oils and grease and lubricants recommended and authorized by UTIFORM. Bear in mind that
the lubricants chosen should comply with all safety regulations particularly in respect of fire hazard, due
to oil or explosions and the possibility of formation or transformation of dangerous gases.
3. The person responsible for the machine should ensure due compliance with all regulations with respect to
the handling, maintenance of the machines and tools.
4. Maintenance, servicing and repair work should only be carried out by qualified personnel if necessary
under the guidance of a person specially trained in this work.
5. If there is any suspicion or indication that a part in the machine interior has overheated, the machine
should be disconnected. Under no circumstances should you open the control caps before the machine has
cooled down sufficiently, in order to avoid the machine catching fire when the oil vapors mix with
oxygen.
6. All maintenance work should be carried out when the machine is stopped.
7. Prior to dismantling any pressurized part, disconnect the compressor or all the equipment pressure
sources and release pressure from the whole system. In addition, all valves should have a sign stating
“work in progress" on the machine "do not open.”
8. Prior to starting repair work, ensure that the installation cannot be connected either through
carelessness or accident. As a further safety measure, place a warning notice on the starter device
stating “Machine repair in progress, do not connect”.
In installations using diesel, the battery should be dismantled or insulating covers should be placed over
the clamps
If the installation is electric, the main switch should be off and all the safety devices should be
deactivated. Place a warning sign on the short circuit box or the main switch stating “Machine repair in
progress, do not connect”.
9. Limit values (pressure, temperature, revolution adjustment etc. ) should be clearly marked.
10 Never activate machines or tools which are either over or under their limit values (pressure,
temperature, number of revolutions, etc.)
11 Keep an operation log, noting operation data and maintenance work carried out.
12. The HD-50/07should be kept clean at all times, that is, free from oil and other residue and dust.

13. Control and clean regularly heat transmission surfaces (cooling blades, intermediate cooler, water
jackets etc.) so as to avoid temperature rise.
14. Carefully check all regulation and safety devices to ensure optimum operation. These must never be out
of service.
15. Avoid damaging safety valves and other pressure reducing devices. Be careful in particular with dirt
from the cement, fine sand or accumulated fibre, which could affect the operation of the devices.
16. Regularly check the pressure and temperature indicators. If acceptable limits are exceeded they should
be changed.
17. Use only original Utiform replacement parts.
18. In order to check the perfect state of the safety devices, you should follow the steps indicated in the
maintenance plan in the instruction manual.
19 DO NOT use flammable solvents, combustible Diesel or carbon tetrachloride to clean parts. Apply safety
measures for protection against noxious vapor from cleaning products.
20. Take extreme care when cleaning during repair work. Avoid dirt by covering parts and openings with a
clean cloth or masking tape.
21. Protect the motor, alternator, air filter, electrical components, regulation devices etc. against damp when
steam cleaning.
22. If you have to carry out work on a machine which causes heat, flames or sparks, the nearby
components should be protected with anti-inflammatory material.
23. Never check the inside of the machine, a pressure vessel etc. using a light with a flame.
24. Place the traction bar and the axle(s) in safe position in moveable machines, if you are working
underneath, or remove a wheel. DO NOT rely on jacks.
25. Prior to dismantling or servicing a HD50/07, motor or any other machine, ensure that all moving parts
weighing over than 15 kg cannot roll or move in any way.
26. When you have finished the repair work, always check that no tools, loose parts or cleaning rags have
been left on top of the machine, on the drive motor or on any other activating mechanism.
Check the direction of the rotation of the electrical motors at every start up and after every change in
connections or electrical repairs, to ensure optimum effect of the oil pump and the ventilator

3 Transport
3.1 Special safety indications
• If there is a machine change on site, the mixing and transport tanks should be empty and the machine parts
should not be pressurized.
• Only use an appropriate transport or traction vehicle with sufficient towing load and support.
• Correctly attach the hook to the traction vehicle.
• For safety reasons the trailer should only be moved by two people. Make sure there is always another person
at hand to help.
• If the machines are new or the wheels have just been changed, retighten the screws of the wheels after
travelling a few miles with the rotation moment marked.
3.2 Crane Transport
When moving a machine from site with a crane, the machine has to be attached at two points on his
back and a point at its front. View recommended lifting kit fromUtiform.
- Remove or attach all loose parts which could fall when the machine is lifted.
- A technical expert should remain close to the crane driver or should be in contact with him by megaphone.
- Then hang the machine on the crane.
- For raising the machine, use hoisting equipment and machinery with the appropriate capacity.
- Check beforehand that this equipment has been serviced and approved according to local security
regulations.
- If the machine or machine parts are lifted using one or several hoisting openings, loading hooks and shackles
should be used. Do not place cables, chains or ropes directly in the hoisting openings.
- Never use bent loading hooks etc. and attach them in such a way that they are always subject to force in
alignment with the axis of the load support.
- In this case a beam may be placed between the hoist and the load. Also two hoists may be used, bearing in
mind that these cannot be inclined at an angle of more than 30º against the vertical. The support capacity of a
hoist diminishes if the lifting force is not vertical.
- In all cases attach the machine in such a way that it can be vertically lifted and cannot rotate or overturn.
- Be careful with the load and do not work too fast. Acceleration and deceleration should be within reasonable
limits.
- Do not leave the load hanging in the hoist.
- Ensure that no one is in the danger zone surrounding the load.

3.3 Towing items
All work of adjustment to or assembly of transport elements shall only be carried out by the vehicle manufacturer or
authorized personnel.
Obviously, welding work should not be carried out on any part of the trailer.
In winter, transport elements should be washed with water after road transport, particularly if there is salt on
the road.
Regularly remove any encrusted dirt from the suspension axle.
The identity plaques of the trailer elements should be kept in perfect state as they should always be legible.
This way, when repairing or ordering spare parts, it is always possible to provide the manufacturer with the
specifications and details stamped on the identification plate.

3.3.1 Main chassis
The main chassis is specially constructed with quality steel which provides excellent stability for the
machine in operation.
3.3.2 Jockey wheel
This support wheel does not require any particular maintenance.
Turn upwards, lift and check the support wheel while the machine is in operation. To place it in working position,
turn the support wheel downwards until the chassis is in horizontal position. The transfer wheel can only be placed
upwards by the support protective device when it is in unloaded state. This procedure is initiated manually.
Deployment is automatic. In the folding position the transfer wheel blocks on its own.

3.3.3 Hand brake or parking brake
Hand brake which is supported by elastic gas suspension serves to safely park the machine. When the chassis
goes backwards the hand brake automatically adjusts.
- Handling the model with elastic suspension using gas: pull the hand brake until in neutral.
- To release the brake, the handle should be replaced in zero position passing through neutral.
- Handling the model with spring cylinder; pull the handbrake up to the last ratchet.
3.3.4 Retention device
When the traction vehicle brakes, or goes downhill, the traction bar is introduced, the brake responds
according to the size of the force of the trailer shaft.
Also when moving in reverse, the brake responds at first. Since the brake drum moves backwards, the effect
of the brake is almost eliminated. When adjusting the retention device, ensure that it is parallel to the main trailer
shaft. If not, the brakes will not function.
.
3.3.5 Coupling head ball or pin
The chassis is prepared depending on the option chosen for transport by car (ball) or by lorry (pin).
National regulations of the countries where the machine is to be transported should be observed.
3.3.6 Middle part of tow bar
The middle part is the connection between the retention device and the tow shaft.
3.3.7 Tow shaft
The tow shaft has a regulator. This means that the height for the transport coupling can be easily and
conveniently regulated.
Before every journey check the safety of the towing bar regulator.
• Bear in mind that when regulating the height of the retention device it is parallel to the towing bar.
Check that the toothed heads are correctly fitted together and that the attachment handle is properly
tightened, and that the safety ring is correctly inserted. If not, there is no guarantee that the brakes will work.
• If there is a ring as traction device, check that the traction vehicle’s blocking system is properly
fitted. If it has a head, check that this is correctly coupled on the ball of the traction vehicle.
• Change the height only in flat areas.
• Secure the machine with the brake block to stop it rolling, then release the handbrake.
If a specific height is maintained for long periods, the toothed head coupling may rust and deteriorate,
therefore regular cleaning of the toothed coupling is recommended.
Periodic maintenance work should be carried out on these elements checking the state of the toothed heads
and the threads, rivets and attachment handles. If a part appears to be excessively worn, it should be replaced.
WARNING! The safety ring is absolutely essential. It must be replaced in the event of loss or wear. Check the
state of the brake cable of the inertia coupling, and the safety cable.
3.3.8 Suspension axle
The suspension axle does not need maintenance and cannot be lubricated as the grease may attack the rubber
elements.

www.utiform.com departamento.té[email protected] Tfno. + 34 96 570 29 82 Fax: + 34 96 570 29 83
Do not carry out welding work on the axle.
3.3.9 Pneumatic Wheels
When changing the wheel, ensure that the correct axle housing corresponds to the wheel couplings.
• Tighten the ball screws with the turning moment marked
• The tires should correspond with the axle specifications.
3.3.10 Inertia brake
Only have brakes repaired in an authorized garage and only use original parts
The wheel brakes fulfill the regulations on toxic substances and EU regulations.
3.3.11 Brake supports and blocks
Fix the wheels with both brake blocks, both on flat surfaces as well as on slopes to prevent the vehicle from
rolling.
3.3.12 Trailer lights system
The light bar is available in the version for 7 pole plug from 12 V and 24 V. This light system is assembled
as follows:
• Take the light bar and place it at the back of the machine, attaching it with the two spring pins
designed for the purpose.
• Take the lighting cable with its normalized pug for the lighting bar, and connect to the 7 port base on
the side of the machine.
• Connect the plug to the front of the trailer in the area of the tow shaft and connect it to the traction
vehicle.
• For dismantling carry out the process in reverse.
If a 12 V traction vehicle is used, the cable may be immediately connected to the vehicle.
If a 24 V traction vehicle is used, a 12 V to 24 V adaptor is required (consult us providing item reference)
If driving a vehicle with a EURO plug, 12 V to EURO adaptor is required (consult us providing item
reference)

5.1 Control Panel
The motor compressor has the requisite safety devices to guarantee correct operation, while guarding against
breakdowns produced by anomalous work situations.
In case of stoppage, failure is indicated in the instrument panel. Details of the safety devices are indicated
below:
5.1.1 Air pressure meter (PT)
Indicates work pressure of the unit. It is situated inside the machine on the gas-oil tank.

5.1.2 Thermo contact temperature air-oil mix (TM)
Stops the machine if it reaches over 110ºC in the compressor drive, indicating the fault via the pilot light L1
of the electrical panel.
When the unit is working on full load, the correct operating temperature is 60 to 65ºC plus the ambient
temperature.
Maximum ambient temperature is considered to be between 40 and 45ºC, depending on the work
load.
It is not possible to restart the unit until the L3 pilot light goes out.
5.1.3 Hour counter (H)
Indicates the number of hours the unit has worked and serves for checking when maintenance and regular
servicing is due.
5.1.4 Hot wire
Protects the installation from short circuits in the electrical system. It is restarted manually. Regulation is set
at 20A.
5.1.5 Motor oil Pressure switch (P)
Measures the pressure of the oil in the motor and if this does not exceed a specific value, it stops cutting
power to the solenoid (SOL) and this is indicated in the L3 light on the electrical panel.
5.1.6 Temperature motor oil (T). Thermo contact
Stops the unit when the motor oil temperature is excessive. This is indicated by the L1 light on the electrical
panel.
5.1.7 Battery charge light.
Indicates that the battery charging system is working correctly. It should be off when the motor is working.
The L5 light on the panel should light up when the contact is activated and the motor is off. When the motor
starts up the L5 light should go off.
5.1.8 Excess air pressure
All the equipment has a safety valve (SV) located in the air-oil tank, tarred at a 10% more than the maximum
work pressure of the equipment, and able to evacuate all the flow produced by the compressor.
