Danger of tipping when driving round
bends at high speed.
– Drive slowly when cornering.
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 10%.
– It is important to follow all safety instruc-
tions, rules and regulations applicable
for driving motor vehicles.
– The operator must use the appliance
properly. He must consider the local
conditions and must pay attention to
third parties, in particular children, when
working with the appliance.
– 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.

– The appliance must not be operated by
children, young persons or persons
who have not been instructed accord-
ingly.
– It is strictly prohibited to take co-pas-
sengers.
– Ride-on appliances may only be started
after the operator has occupied the driv-
er's seat.
 Please remove the ignition key, when
not in use, to avoid unauthorised use of
the appliance.
 Never leave the machine unattended
so long as the engine is running. The
operator may leave the appliance only
when the engine has come to a stand-
still, the appliance has been protected
against accidental movement, if neces-
sary, by applying the immobilization
brake and the ignition key has been re-
moved.
Appliances with high emptying
system
DANGER
Risk of injury!
– When working on the high emptying
system, completely lift and secure the
waste container.
– Perform the safeguarding only from
outside the hazard zone.
Machines with driver cabin
ATTENTION
The overhead guard protects the driver
against larger falling objects. As a canopy it
offers additional protection against weather
conditions. However, it does not provide
rollover protection!
In emergencies, destroy the windows with
a hammer.
Safety information concerning the
combustion engine
DANGER
Risk of injury!
– Please observe the special safety infor-
mation in the operating instructions of
the engine manufacturer.
– 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).
– Gas engine: When operating the appli-
ance indoors, ensure sufficient ventila-
tion and discharge of the exhaust gases
(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 with liquid gas
than with petrol.
WARNING
Risk of injury!
– Use only liquid gas cylinders filled with
power gas in accordance with DIN
51622 of A or B quality, depending on
the ambient temperature.
For the gas engine, use only liquid gas
mixtures of propane/ butane or their
mixtures where the mixing ratio lies be-
tween 90/10 to 30/70. Because of the
better cold start behaviour, liquid gas
with a high propane proportion should
be preferred with ambient temperatures
below 0 °C (32 °F) as the vaporization
already takes place with low tempera-
tures.
ATTENTION
The use of household gas and camping
gas is strictly prohibited.
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 "bottom" marking while
connecting a full cylinder (the connec-
tion screw points vertically downward).
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.
– 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
