2.6 Operation of the screed
2.6.8 Screed gas heating
To heat the screed with gas, liquefied propane-butane (LPG) can
only be used.
The maximum gas bottle volume which may be placed on the
machine is 10 kg (22 lb).
It is prohibited to use natural gas for screed heating.
The screed heating system is designed for a maximum operat-
ing pressure of 1 bar with a total gas consumption of 10 kg/h
(22 lb/h).
The recommended operating pressure for screed gas heating is
from 0.6 bar to 0.8 bar, the gas consumption of a burner is ap-
prox. 200 g/h (0.44 lb/g).
Propane-butane (LPG) is an extremely flammable substance
and any leakage causes a high risk of fire or explosion!
Propane-butane (LPG) is heavier than air and may accumu-
late in lower places – danger of fire or explosion!!
Do not smoke during machine operation. There is a risk of
explosion or fire. Liquid gas can easily ignite.
The machine must be equipped with a fire extinguisher.
Have the fire extinguisher ready on the driver's stand at
a place intended for this purpose.
Caution! Risk of explosion, if the screed gas heating is oper-
ated incorrectly, or safety and fire instructions for using and
handling gas bottled are not adhered to.
Operate the screed heating system always according to the
operating manual delivered with the machine.
Adhere to the national regulations in the country where the
machine is operated. Familiarize yourself with these regula-
tions and observe them.
It is prohibited to use natural gas for screed heating.
Operate the machine only with the liquefied propane-bu-
tane (LPG). Propane-butane (LPG) is an odourless liquefied
gas.
In some countries, in which the machine is operated, gas
manufacturers odorize odourless gasses due to safety rea-
sons (by adding aromatic substances), so that a leak can be
identified easily.
In such cases pay higher attention to a potential gas leak
during operation of the machine, which is manifested by an
odour, and close the gas inlet.
In case of gas leakage, in some cases it is impossible to rely
on the gas odour as a sign of gas leak from the system.
During the operation of the machine visually check that the
gas system is undamaged.
Regularly check the gas system according to the mainte-
nance plan given in this manual, especially hoses, valves
and other components.
Always require a material safety data sheet to the delivered
gas bottle. Before mounting the gas bottle on the machine,
read and check that the gas bottle meets all conditions for
putting the machine into operation.
Risk of burns! The screed may reach the temperature of up
to 130°C.
Stop the gas leakage.
In case of gas leakage, inform relevant national author-
ities.
