DANGER

Immediate danger that can cause severe 

injury or even death.

몇

WARNING

Possible hazardous situation that could 

lead to severe injury or even death.

CAUTION

Possible hazardous situation that could 

lead to mild injury to persons or damage to 

property.

Hauptverband der gewerblichen Beruf-

sgenossenschaften e.V. (HVBG / Germa-

ny). Liquified gases (propellants) are 

butane and propane or a mixture of butane/

propane. They are available in special cyl-

inders. The operating pressure of these 

gases depends on the outside tempera-

ture. 



Danger

Risk of explosion! Do not handle liquified 

gas like petrol.  Petrol evaporates slowly, 

liquified gas immediately turns into gas.  

The risk of gas spreading in the room and 

getting ignited is thus higher in case of liq-

uefied gas than in petrol.



Danger

Risk of injury! Use only liquefied gas cylin-

ders with propellant filled according to DIN 

51622 of A or B quality, depending on the 

surrounding temperature.

CAUTION

Use of cooking gas is strictly prohibited. For 

the gas engine, use only liquid gas mix-

tures of propane/ butane or their mixtures 

where the mixing ratio lies between 90/10 

to 30/70. On account of better cold start be-

haviour even at low outside sub-zero tem-

peratures (below 0° C / 32 °F) always 

prefer a mixture with a higher propane 

share because evaporation takes place 

even at low temperatures.

–

All persons handling liquid gases are li-

able to acquaint themselves with the 

special properties of the liquefied gases 

for hazard-free handling of operations.  

The current documentation is always to 

be kept with the sweeper. 

–

Propellant-operated units are to be 

checked at regular intervals, at least 

once a year, by an expert against leaks 

(according to BGG 936) and ensure 

that the unit is functioning properly. 

–

The inspection must be certified and 

documented. The inspection guidelines 

are § 33 and § 37 UVV (occupation ac-

cident prevention regulations) "Use of 

liquid gas" (BGV D34). 

–

General applicable regulations are the 

guidelines for inspecting vehicles 

whose engines are driven by liquefied 

gases of the Federal Transportation 

Minister. 

–

Gas must always be drawn only from 

one cylinder. Drawing gas from multiple 

cylinders simultaneously can cause liq-

uid gas from one cylinder flowing into 

the other. This causes the over-filled 

cylinder to be subjected to an unpermit-

ted excess pressure when the cylinder 

valve is closed later (refer B.1 of these 

guidelines). 

–

Ensure the correct positioning of the 

cylinder with the "top" marking while 

connecting a full cylinder (the connec-

tion screw points vertically upward). 

Perform the replacement of the gas cylin-

der carefully. During assembly and disas-

sembly, the gas outlet nozzle of the 

cylinder valve must be sealed by means of 

a cap nut that is tightened using a wrench.

–

Discontinue the use of leaky gas cylin-

ders. Such cylinders are to be emptied 

by slowly letting out the gas in open 

spaces by conforming to all safety reg-

ulations and are to be indicated as 

leaky. Also inform the issuing company 

or its representative (the filling-station 

attendant) in writing about the damage 

to the cylinder while delivering or re-

ceiving the cylinders. 

–

Before connecting the gas cylinder, 

check that its connection neck is in a 

proper state. 

–

After connecting the cylinder, regularly 

check that it is not leaky by using a 

foaming agent. 

–

Open the valves slowly.  Do not use 

hammers to open and close the cylin-

ders. 

–

Use only dry fire extinguishers (with 

carbonic acid gas) in case of fire 

caused by liquefied gases. 

–

The entire LPG unit must be continu-

ously checked to ensure that there are 

no leaks and the unit is functioning 

properly. Using the vehicle with a leaky 

gas unit is strictly prohibited. 

–

First close the cylinder valve before 

loosening the pipe or tube connection.  

Unscrew and loosen the connection nut 

of the gas cylinder slowly because oth-

erwise the gas under pressure in the 

tube will flow out instantly. 

–

If the gas is refilled from a larger tank, 

then ask the sales agent of the LPG 

about the important regulations to be 

followed. 



Danger

Risk of injury!

–

LPG in a liquid state can cause frost 

bites on bare skin. 

–

After disconnecting the cylinder, tighten 

the closing nut firmly on the connecting 

threading of the cylinder.

–

Use soap water or some such foaming 

agent to check whether the cylinder is 

leaking. The use of open flames to illu-

minate the LPG unit is strictly prohibit-

ed.

–

Follow the manufacturer's installation 

specifications while changing individual 

parts of the LPG unit. Close all cylinder 

and locking valves while doing so.

–

Regularly check the status of the elec-

trical unit of the LPG vehicles . Sparks 

can cause explosions if the gas-carry-

ing parts of the unit are leaky.

–

If a LPG-driven vehicle has been idling 

for a long time, then first ventilate the
