

Danger

Risk of injury!

–

Please follow the special safety instruc-

tions in the Operating Instructions Man-

ual for petrol engine devices. 

–

Do not close the exhaust. 

–

Do not bend over the exhaust or touch 

it (risk of burns). 

–

Do not touch the drive motor (risk of 

burns). 

–

Ensure that there is adequate ventila-

tion or provision for diverting the ex-

haust gas while operating the appliance 

in closed rooms (risk of poisoning).

–

Exhaust gases are poisonous and haz-

ardous to health, do not inhale them.

Hauptverband der gewerblichen Beruf-

sgenossenschaften e.V. (HVBG / Germany). 

Liquified gases (propellants) are butane and 

propane or a mixture of butane/propane. 

They are available in special cylinders. The 

operating pressure of these gases depends 

on the outside temperature. 



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 guide-

lines are § 33 and § 37 UVV (occupa-

tion accident 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). 

Replace cylinders carefully. While connect-

ing and disconnecting the gas cylinders, 

the gas outlets of the cylinder valve must be 

closed properly by tightening the locking 

nuts with a spanner. 

–

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 ham-

mers to open and close the cylinders. 

–

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 

setting room before commissioning the 

vehicle or its electrical unit. 

–

Immediately inform the trade associa-

tion and the concerned trade superviso-

ry authority about accidents with gas 

cylinders or LPG units.  Store the dam-

aged parts carefully until all investiga-

tions have been completed.

–

Propellants or LPG cylinders must al-

ways be stored according to the regula-

tions of TRF 1996 (Technical 

Regulations for Liquid Gases, refer DA 

to BGV D34, Appendix 4). 

–

Always store the gas cylinders in a ver-

tical position. Use of open flames and 

smoking at the installation site of the 

cylinders and during repairs is strictly 

prohibited. Protect the stored cylinders 

against unauthorised access. Close all 

empty cylinders properly. 

–

Close the cylinder and main locking 

valves immediately when you switch off 

the vehicle. 

–

Follow the regulations for garages and 

the construction guidelines of the re-

spective State about the location and 

structure of the parking areas for LPG-

driven vehicles.  

–

Gas cylinders are to be stored in sepa-

rate rooms away from the parking areas 

(refer DA to BGV D34, Appendix 2). 

–

The electrical hand-held lamps used in 

the rooms are to be equipped with 

closed, sealed case and a strong pro-

tection cover. 

–

Close all cylinder and main valves be-

fore working in repair workshops and 

protect the gas cylinders against effect 

of external heat. 

–

A responsible person must check that 

all valves, especially the cylinder 

valves, are closed during operational 

breaks and before closing the factory.  

Do not carry out any jobs involving fire - 

such as cutting and welding jobs - in the 

vicinity of the gas cylinders.  Do not 

store gas cylinders, not even empty 

ones, in the workshops.  

–

The parking and storage rooms and the 

repair workshops must be ventilated 

properly. Please note that liquefied gas-

es are heavier than atmospheric air. 

They get collected on the floor, in re-

cesses and other holes in the floors and 

form a gas-air mixture that can lead to 

explosions. 

–

The engine is to be brought to a stand-

still and the appliance is to be fastened 

properly during transportation. 

–

Switch off the appliance and remove 

the ignition key prior to performing any 

cleaning or maintenance tasks on the 

appliance, replacing parts or switching 

over to another function.

–

Always disconnect the battery when 

working on the electrics.

–

Do not clean the appliance with a water 

hose or high-pressure water jet (danger 

of short circuits or other damage).

–

Maintenance work may only be carried 

out by approved customer service out-

lets or experts in this field who are famil-

iar with the respective safety 

regulations. 

–

Please observe the local safety regula-

tions regarding portable commercially 

used appliances.

–

Always use appropriate gloves while 

working on the device.
