A Correct use and application
AThe “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 guide-
lines are part of the present operating instructions and must always be heeded. Na-
tional 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 lean-
mixed concrete, track-laying ballast and unbound mineral aggregates for foundations
for paving.
This machine shall be used, operated and maintained for the purposeof the intended
work as included in the operation manual. Any other use is regardedas 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 im-
proper use and is expressly forbidden! Especially in those cases where the paver fin-
isher is to be operated on inclines or where it is to be used for special purposes
(constructionof dumps, dams), itis absolutely necessary tocontact the manufacturer.
Duties of the user: A “user” within the meaning of the present operating instructions
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 be-
tween the owner and the user of the paver finisher, is charged with the observation
of the operating duties.
Theusermustensure that the paverfinisheris only usedin the stipulatedmanner 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 prevention regulations and other
safety-related provisions as well as the operating, servicing and maintenance guide-
lines are observed. The user must also ensure that all persons operating the equip-
ment 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 attachments that willinterfere with or supplement the functions of the paver fin-
isher is permitted only after written approval by the manufacturer has been obtained.
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 Dynapac VB340 screed is operated in conjunction with a paver finisher.
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.
AThe hydraulically extendable screed is intended for laying with variable operating
widths.
For the technical specifications of the screed, refer to the section ”Technical Data”.

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 tex-
ture.
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 differ-
ent materials and layer thicknesses.
Basic screed and extendable parts: 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.
AThese adjustments, the basic adjustments of the screed in relation to the paver fin-
isher and adjustment of the crowning are described in chapter E, „Set-up and modifi-
cation“.
Extension parts: 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 only be folded up for a short time in special cases (e.g. ma-
terial to be laid along a wall).

B_VB340_Dyn_05.08_GB.fm. 3-12 -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.
Theelectronic temperature and flamemonitoring system ensures short heating times
and constant temperatures.
Air guides to the tamper knives and side plates ensure efficient use of heat.
Electric heater: The advantages of the electric screed heater are its tried-and-tested
design, problem-free handling and maximum possible service friendliness thanks to
maintenance-free
operation.
Short heating times, constant temperatures and efficient heat utilisation are therefore
assured thanks to the various, separately monitored and controlled heating 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 con-
nection 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.
ABoth 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 Safety
fThe safety devices of the paver finisher and of the screed are described in chapter B,
section 3 of the operating instructions for the finisher.
3.1 Remaining risks at the screed
Danger of squeezing!
fAt all moving parts of the screed, there is a danger of crushing, trap-
ping or shearing.
Keep away from these parts!
Danger of being pulled in!
fA danger of catching, winding or drawing-in exists at all rotating or
circulating parts of the screed.
Keep away from these parts!
Danger of falling!
fNever jump on or off the when the machine is in motion! Only use
the access boards and steps provided!
fDanger of fire and explosions!
Work on the heater system involves the danger of fire and explo-
sion.
Do not smoke! Do not use open fires!
Danger of electric voltage
fAny failure to follow the safety precautions and safety regulations
when operating the electric screed heater (o) leads to the risk of
electric shock.
Danger to life!
All maintenance and repair work on the screed's electrical system
may be carried out by a specialist electrician only.
