A Correct use and application
A
The “Guidelines for the Correct Use and Application of Paver finishers” compiled by
Dynapac are included in the scope of delivery for the present machine. The guidelines are part of the present operating instructions and must always be heeded. National regulations are fully applicable.
The road construction machine described in the present operating instructions is a
paver finisher that is suited for laying mixed materials, roll-down concrete or leanmixed concrete , track-layi ng ballast and unbound m ineral aggregate s for founda tions
for paving.
This machine sh all be u sed, operat ed and ma intained for the pu rpose of the intended
work as included i n the oper ation manual. A ny other u se is regarded as improper use
and can cause injury to persons or damage to the paver finisher or other equipment
or property.
Any use going beyond the range of applications described above is regarded as improper use and is expr essly forbidden! E specially in those cases wher e the paver finisher is to be operated on inclines or where it is to be used for special purposes
(construction of dump s, dams), it is absolutely necessary to contact the m anufacturer.
Duties of th e u ser : A “ user” wi thin the m eaning of the presen t ope rati ng instru cti ons
is defined as any natural or legal person who either uses the paver finisher himself,
or on whose behalf it is used. In special cases (e.g. leasing or renting), the user is
considered the person who, in accordance with existing contractual agreements between the owner and the user of the paver finisher, is charged with the observation
of the operating duties.
The user must ensure that th e paver finisher is only used in the stipu lated mann er and
that all danger to life and limb of the operator, or third parties, is avoided. In addition
to this, it must be ensured that the relevant accident pr evention regulat ions and othe r
safety-related provisions as well as the operating, servicing and maintenance guidelines are observed. The user must also ensure that all persons operating the equipment have read and understood the present operating instructions.
Mounting of attachments: The paver finisher must only be operated in conjunction
with screeds that have been approved by the manufacturer. Mounting or installation
of any attachment s that will interfere with or supple ment the functions of the paver finisher is per mitted only after w ritten a ppro val by the ma nufact urer has bee n obtain ed.
If necessary, the approval of local authorities has to be obtained.
Any approval obtained from local authorities does not, however, make the approval
by the manufacturer unnecessary.

B Description of the screed
1 Application
The SVEDALA D EMAG EB 34 screed is ope rated in conjuncti on with a paver finish er .
The screed is used for laying:
- bitumen materials,
- roll-down concrete or lean-mixed concrete,
- track-laying ballast or
- unbound mineral aggregates for foundations for paving.
B_EB34_DEM_05.08_GB.fm. 1-12 -01.01.07
VB340.wmf
A
The hydraulically extendable screed is intended for laying with variable operating
widths.
For the technical specifications of the screed, refer to the section ”Technical Data”.
B 1
2 Assemblies
Tamper and vibration elements: The tamper knives converging in the middle area
prevent seams in the middle.
Auxiliary vibration (option) supports the compacting process, thus improving the texture.
The tamper and the vibration elements can be individually switched on and off and
controlled with regard to speed.
Continuous speed control always ensures optimum compacting results for the different materials and layer thicknesses.
Basic scre ed an d ext endab le pa rts: The screed parts which can be hydraulically
extended from the middle section („basic screed“) extend the working width of the
screed at the push of a button.
An expensive guide system ensures high levels of stability.
The angle and the height of the extendable parts in relation to the basic screed can
be quickly and easily readjusted.
A
These adjustments, the basic adjustments of the screed in relation to the paver finisher and adjustment of the crow ning are d escri be d in chap ter E , „Set- up a nd mo di fication“.
Extensio n pa r ts : The working width can be increased through the use of extension
parts which are very simple to install.
Side shields: The side shields serve to prevent the material from overflowing to the
outside.
- Heated side shields
- Cut-off shoes
Hinged walkway plates: During installation, the hinged walkway plates should be
folded down and snapped into place.
The walkway plates may on l y be folded up for a short tim e in speci al cases ( e.g. ma terial to be laid along a wall).
B 2
B_EB34_DEM_05.08_GB.fm. 2-12 -01.01.07
Screed heater system: Two different heater systems are available as options:
Gas heater: The propane gas flame band heater features a tried-and-tested design
and is easy to handle.
The electronic te mperatur e and f lame monito ring system ensures short hea ting times
and constant temperatures.
Air guides to the tamper knives and side plates ensure efficient use of heat.
Electric h eater: The advantages of the electr ic screed he ater are its trie d-and-te sted
design, problem-free handling and maximum possible service friendliness thanks to
maintenance-free
operation.
Short heating times, con stant temperature s and efficien t heat utilisation are the refore
assured than ks to the various, separ ately m oni tored and contr ol led he ating sections.
These are designed in the form of heating strips, sensibly arranged in the bottom
plates and tamper knives of each screed section.
If extension parts are fitted to the screed, only one single, easily installed plug connection need be fitted to the supply and control cable leading to the neighbouring
screed component.
The heating system is monitored and controlled in the switch cabinet.
A
Both types of heater and their operation are described in the following chapters of
these operating instructions.
Symbols are assigned to the different descriptions and figures:
- Description / depiction when equipped with gas heater
- Description / depiction when equipped with electric heater

3.3 General notes on the gas heater system
The heater of the screed burns propane
gas (liquefied gas). The gas bottle
stands on the finisher.
The heater is equipped with an electron ic flame and a temperature monitoring
system.
GHeiz_340.cdr
Heed the following points before commissioning the heater system:
29
- The gas bottles must always be in the
position provided for this purpose on
the screed, and must be secured using the supplied strap retainers.
The bottles must be fixed in position
so that they cannot turn around their
longitudinal axis even while the paver
finisher is in operation.
- The liquefied gas system must not be
operated without the hose rupture protection device (29). It is also absolutely necessary that the pressure
reducing valve is installed before the
system is put into operation.
Gasflas.tif
- The gas pressure must not fall below
1.0 bar. Danger of explosion in the burner!
- All gas hoses must be checked for external damage before use, and must be immediately replaced with new hoses if any defects are found.
f
D 8
There is a danger of fire and explosions when handling gas bottles and working on
the gas heater.
Do not smoke! No naked flames!
D_E34_VB340_05.08_G B.fm 8-26 -01.01.07
3.4 Connection and leak test
The gas pipe system of the basic screed
and the extend able pa rts is permanently
installed. To connect the gas bottles:
- Unscrew the protective caps from the
bottle valves and screw onto the rear
of the bottle bracket.
- Check whether the q uick action valves
are closed.
- Check that the bottle valves (30) are
properly closed.
Install the gas h oses with the pressure
reducers and the hose rupture protection devices (29) on the bottles.
A
Note:
The gas connections always have left-handed threads!
29

two gas bottles.
- Check whether the battery master
switch is switched on.
- Open the bottle valves (30).
Unlock the safety valve by pressing
the hose rupture protection device
(29).
- Open the quick action valves.
A
The following sequence must be adhered to in order to guara ntee a malfunction-free ignition and heating phase:
- 1. Place screed on the ground
- 2. Fully retract the finisher's levelling cylinders
- 3. Ignite the screed and allow to heat slightly in this position
- 4. As soon as sufficient heat is available, the screed can be raised
29
Gasflas.tif
30
Ignition process
- Switch on the On/O ff switch (27) in the
switch cabinet (upwards).
- This opens the electromagnetic
non-return valves for the gas supply
to the burners;
- It activates the electronic ignition
system, causing the gas to be automatically ignited by the spark plugs
and controlled by the flame monitoring system.

Via the temperature sensor and flame monitoring system, the electronics monitor gas
heater operation. If there is no stable flame at the ignition burner within 7 seconds,
the electronics indi cate a malfun ction. Th e gas supply is interrup ted and the red indi cator lamps on the ignition box and in the switch cabinet light up.
A
m
3.7 Setting the temperature level
In the event of a malfun cti on duri ng the switch-on phase, the starting process can be
repeated up to three times. If the malfunction still occurs after three start-ups, the
cause of the malfunction has to be eliminated before starting again.
When the flame is correct, the screed is heated until the temperature sensors in the
individual screed s interrupt the heating process. Du ring the heating phase, the yellow
indicator lamps (12, 13, 14, 15) in the switch cabinet and the yellow indicator lamps
on the ignition boxes (35) indicate a correct flame at the burners.
In the event of a malfunction, the red indicator lamps (16, 17, 18, 19) in the switch
cabinet and the red indicator lamps on the ignition boxes (34) indicate that the flame
at the burners is not correct.
The indicator lamps are important for trouble-free operation of the ignition system.
Therefore, defective bulbs should be immediately replaced!
Temperature level controller for the basic screed (9)
>: Higher temperature
<: Lower temperature
A
Temperature level controller for extendable parts (10)
>: Higher temperature
<: Lower temperature
Use the high temperature to preheat the
screed and the extendable parts/extension parts before starting work; this prevents bitumen materials from sticking to
the tamper knives and to the bottom
plates on the first meters laid.
Usually, the switches can be toggled to the low temperature after a short time.

3.8 Switching off the heater
After work has been comp leted, or when
the heater is no longer required:
- Switch off the On/Off switch (8) in the
switch cabinet.
- Close the quick action valves and both
bottle valves (30).
m
If these valves are not closed, there is a
danger of fire and explosion due to the
possible escape of uncombusted gas!
Always close the valves during breaks
and after work has been completed!
3.9 Exchanging the gas bottles
- Check whether the q uick action valves
and both bottle valves (30 ) are closed.
- Unscrew the gas hoses.
- Screw the protective caps for the bottle valves onto the gas bottles.
- Screw pressure reducer onto the
available mounting bracket.
8
GHeiz_340.cdr
30
f
Gas bottles that are full or not compl etely
emptied are under pressure.
Therefore, make sure that bottles with
their protective valve caps removed are
protected from severe impact (particularly in the area of the valves or on the
valves themselves)!
Gasflas.tif
- Connect new gas bottles (see section 3.4, „Connection and leak test“).

4.2 General information on the heating system
The electric heating system is supplied
with power by a generator on board the
paver which is controlled fully-automatically controlled in accordance with requirements.
Heating resistors in the form of heating
strips ensure direct temperature transition and even distribution of heat.
Each screed section is heated by three
heating strips. Two can be found on the
bottom plate and one on the tamper
knife.
Temperature display and temperature
control are carried out independently of
one another and in an infinitely variable
manner for: The left basic screed, right
basic screed, left extendable part and
right extendable part by means of control unit STC2000 o n the hea ting syste m
switch cabinet.
The heating system is connected to other fitted screed components via simple
plug connections.
As an option, the switch cabine t can also
be fitted with additional 230 volt sockets
for external consumers (e.g. additional
lighting).
Since fuels (gas, diesel) are not handled
and insulation monitoring takes place,
maximum possible prote cti on of person nel is offered.

Beware of hot surfaces! Danger of burning!
Maintenance and repair work on electrical systems with medium voltage levels, e.g.
the screed heating system, may only be carried out by specialist electricians or persons instructe d in electr ical en gineeri ng work if the ap propri ate test devices ar e used.
Always comply with rel evant tech nical elec trical prote ction precau tions. Danger to life
as a result of accidents involving medium voltage levels!

f
f
Inadvertent starting of the paver finisher can endanger persons working on the
screed.
Only carry out such work with the finisher motor at a standstill unless the instruc-
tions state the opposite!
Make sure that the paver finisher is secured against being put into operation.
When lifted, the screed can still slide downwards if the mechanical screed transport
safeguard is not inserted on the finisher.
Only carry out work when the screed is secured by mechanical means!
When connecting or di sconnecting hyd raulic h oses and whe n workin g on the h ydraulic system, hot hydraulic fluid can spurt out at a high pressure.
Switch off the engine and de-pressurise the hydraulic system! Protect your eyes!
Always install exte nsi on p arts and co nversio n par ts in the p rope r m anner ! If in dou bt,
contact the manufacturer!
Mount all protective devices before re-commissioning the paver finisher.
The walking platform must always reach over the entire width of the screed.
The hinged walkway plate (option) may only be folded up under the following conditions:
- If the machine has to be backed up very closely to a wall or another obstacle,
- During transportation on a low-bed trailer.

F_EB34_VB340_05. 08_GB.fm 8-18
A
During operation, bitumen and fine particles enter the tamper frame. Heating keeps
them in a plastic state, thus making them available for lubricating the tamper knife.
When the screed cools down, these substances solidify. They must be liquefied by
heating before the tamper is put into operation again.
- Usually, the only cleaning work required at the end of the day is to operate the
tamper at slow speed for approx. 15 minutes and to spray some separating fluid
into the tamper compartment.
- If the tamper is not to be used for a longer per iod of ti me, the tampe r compa rtment
should be emptied as long as the material is still in a liquid state. If necessary,
switch on the heater!
To empty the tamper compartment, the tamper deflector plates of the screed parts
can be loosened.
- Loosen lock nuts (1) of track rod (2) and slide track rods back slightly so that the
deflector plate folds forwards slightly. If necessary, encourage it to fold forwards.
- Leave the tamper to run for a few minutes until the material has fallen out of the
tamper frame.
- Then retighten lock nut (1) of track rod.
- If necessary, adjust the gap dimension. See chapter E.

If an insula ti on f ault o ccurs dur ing o pera ti on, and the indi cator l am p d isplays a n insu lation fault, the operator may proceed as follows:
- Switch the switches of all external equipment and the heating system to OFF and
press the reset button for at least 3 seconds to delete the fault.
- If the indicator lamp does not go out, the fault lies in the generator.
No further work may be carried out.
- If the indicator lamp goes out, the switches of the heating system and external
equipment can be switched back to ON one after another until a message again
appears and the system is shut-down.
- The equipment found to be faulty must be removed or must not be engaged, and
the reset button must be pressed for at least 3 seconds to delete the fault.
Operation may now be continued - without the faulty equipment, of course.
The generator or electrical consumer found to be faulty must be
checked or repaired by a specialist electrician. Only then may
work again be carried out with the screed and equipment.
