Safety instructions
General notes on safety
– The machine with working equipment
must be checked to ensure that it is in
proper working order and is operating
safely prior to use. Otherwise, the appli-
ance must not be used.
– If the appliance is used in hazardous ar-
eas (e.g. filling stations) the corre-
sponding safety provisions must be ob-
served. It is not allowed to use the ap-
pliance in hazardous locations.
Safety instructions concerning the
operation
– The operator must use the appliance
properly. The person must consider the
local conditions and must pay attention
to third parties, in particular children,
when working with the appliance.
– Prior to starting work, the operator must
ensure that all protective devices are
properly installed and function correct-
ly.
– The operator of the appliance is liable
for accidents with other individuals or
their property.
– Ensure that the operator wears tight-fit-
ting clothes. Wear sturdy shoes and
avoid wearing loose-fitting clothes.
– Check the immediate vicinity prior to
starting (e.g. children). Ensure suffi-
cient visibility!
– Never leave the machine unattended
so long as the engine is running. The
operator may leave the machine only
when the engine has come to a stand-
still, the machine has been protected
against accidental movement, if neces-
sary, by applying the immobilization
brake and the ignition key has been re-
moved.
– The appliance may only be used by per-
sons who have been instructed in han-
dling the appliance or have proven
qualification and expertise in operating
the appliance or have been explicitly
assigned the task of handling the appli-
ance.
– This appliance is not intended for use
by persons (including children) with lim-
ited physical, sensoric or mental capac-
ities or lack of experience and/or skills,
unless such persons are accompanied
and supervised by a person in charge of
their safety or if they received precise
instructions on the use of this appli-
ance.
– Children should be supervised to pre-
vent them from playing with the appli-
ance.

Safety information concerning the
driving operation
Danger
Risk of injury!
Danger of tipping if gradient is too high.
– The falling and rising gradients in the di-
rection of travel may not exceed 16%.
Danger of tipping on unstable ground.
– Only use the machine on sound surfac-
es.
Danger of tipping with excessive sideways
tilt.
– The gradient perpendicular to the direc-
tion of travel should not exceed 15%.
Safety information concerning the
combustion engine
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.
– The engine requires approx. 3-4 sec-
onds to come to a standstill once it has
been switched off. During this time, stay
well clear of the working area.
Safety guidelines for LPG vehicles
(only gas engine)
Hauptverband der gewerblichen Beruf-
sgenossenschaften e.V. (HVBG / Germa-
ny). Liquefied gases (propellants) are bu-
tane 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 pre-
fer a mixture with a higher propane share
because evaporation takes place even at
low temperatures.

Liabilities of the factory management
and the employee
– 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.
Maintenance by expert
– 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.
Commissioning/Operations
– 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 cylin-
der 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.
