Liquefied gas
Only use liquefied gas cylinders with propellant gas filling of Quality A or B,
as specified in DIN 51 622, in accordance with ambient temperature.
KMR 1250 LPG User Instructions English
Note:
The use of domestic gas is absolutely forbidden!
For gas engines it is permitted to use liquefied gas mixtures of propane/
butane whose mixing ratio lies between 90/10 and 30/70.
Owing to the better cold start properties, it is preferable to use liquefied gas
with a high propane proportion for external temperatures below 0 °C (32 °F),
for evaporation begins to take place already at low temperatures.
Replacement parts
Please note that the use of other than original replacement parts can lead to
serious malfunctions and also to bad accidents, if such parts have not been
properly manufactured, or do not precisely replace the original part or lead to
unsafe operation of the appliance. Please always use only original replacement parts.
Accessories
Wrong, non-suitable or defective accessories hamper the functioning of the
appliance. Their use is dangerous. Please use only original accessories.
Otherwise the right to claim under guarantee can be extinguished.
Fire hazard while sweeper is operating!
n Keep highly inflammable materials away from the engine and the exhaust
while the sweeper is operating.
Danger of toppling over on steep slopes!
The sweeper could topple over while it is being driven across or turning
round on a sleep slope.
n The maximum gradient up or down which the sweeper can be driven is 18%.
n Do not drive at right angles to a slope with a gradient steeper than 10%.
Danger of toppling over if bends are negotiated at high speed!
The sweeper could topple over if it is driven round a bend at high speed.
Drive slowly round bends.
Caution when carrying out maintenance or repairs!
In order to prevent the engine from being started unintentionally, proceed as
follows:
n Remove the ignition key.
n Disconnect the battery at the negative terminal.
Caution while handling the battery!
Observe the safety information provided by the battery manufacturer.
Always use batteries and chargers recommended by KÄRCHER, otherwise
your warranty could be rendered invalid.
Caution while transporting the sweeper!
Make sure that the sweeper is secured properly if you are going to transport
it to a different location.
Do not use a forklift truck for loading purposes as it could damage the
sweeper.
n Apply the parking brake.
n Secure the sweeper as shown in the illustration, using
– web belts or
– ropes or
– chains.

On behalf of the
environment
Safety Directives
for LPG Motor
Vehicles
Caution, environmental hazard due to exhausted batteries!
Exhausted batteries should not be treated as domestic refuse. Make sure
that are disposed of in an environmentally appropriate manner.
Caution, environmental hazard due to engine oil or hydraulic fluid!
After you have changed the engine oil or hydraulic fluid, take the waste
product to a recognised collection point or to a waste disposal company.
Liquified petroleum gases (fuel gases) are butane and propane or butane/
propane mixtures. They are supplied in special cylinders. The working pressure of these gases is dependent on the outside temperature.
Caution:
Do not treat liquified petroleum gas in the same way as petrol. Petrol vaporizes slowly. Liquified petroleum gas becomes gaseous immediately. The
danger of gas spreading in an enclosed area and igniting is therefore greater
than with petrol.
Therefore:
Be doubly careful; no open flames – ovens, storm lamps, etc. – do not smoke
in storage locations or when carrying out any kind of work on the LPG system.
Obligations of the factory management and the employee
All persons handling liquefied gas have an obligation to acquire the knowledge regarding the characteristics of liquefied gas which is necessary to
execute their work free of danger. This booklet must always accompany the
sweeper.
Maintenance by experts
Fuel gas systems must be regularly checked by an expert, at least once a
year, for their functioning capability and freedom from leaks (as per ZH 1/57).
The inspection must be attested in writing. The bases for the inspection are §
33 and § 37 UVV (Accident Prevention Regulations) “Use of liquefied gas”
(VGB21 (Association of Superpower Station Operators)).
Initial operation/operation
– Gas may only be used from one cylinder. Using gas from several cylin-
ders simultaneously may result in liquified gas flowing from one cylinder
into another; this will create a non-permissible pressure increase when the
cylinder valve on the overfilled cylinder is subsequently closed (comp. B1
of these guidelines).
– When fitting full cylinders, the correct position of the cylinder is denoted by
“top”. Gas cylinders should be replaced carefully. When installing or
removing, the gas outlet connection fitting of the cylinder valve must be
sealed with a hexagon cap nut which is screwed down with a key.
– Never continue using gas cylinders which are leaking. Following all rele-
vant safety precautions, they should be emptied immediately in the open
air by releasing the gas and then marked as leaking.
When delivering or collecting damaged gas cylinders, the distributor or his
agent (filling station attendant or similar) should be informed immediately
in writing of the existing damage.
– When returning damaged gas cylinders, the distributor or his agent (filling
station attendant or similar) should be informed immediately in writing of
the existing damage.
– After connecting the cylinder, check for leaks using a foaming agent.
– The valves should be opened slowly. They must not be opened or closed
with the aid of striking tools.
In the event of liquified petroleum gas catching fire use only carbon dioxi-
de powder-type fire extinguishers or carbon dioxide gas extinguishers.
28
KMR 1250 LPG User Instructions English
– The entire LPG system must be monitored continuously to ensure that it is
in a safe operating condition and, in particular, is not leaking. The vehicle
must not be used if the gas system is leaking.
– The cylinder valve must be closed before disconnecting the pipe or hose
connection. The connection nut on the cylinder must be opened slowly
and only slightly at first, otherwise the gas which is still under pressure in
the line will flow out spontaneously.
Caution:
Liquified gas which comes into contact with skin causes frostbite!
– Following disassembly, the lock nut must be screwed firmly onto the
connecting thread.
– Soap water, a soap bubble solution or other foaming agents should be
used when testing for leaks. It is forbidden to inspect the LPG system
using a naked flame.
– The installation directions of the manufacturer should be observed when
replacing individual system parts. The cylinder and main shut-off valves
should be closed when doing this.
– The condition of the electrical system of LPG vehicles should be monito-
red continuously. Sparks may cause explosions if system parts which
convey gas are leaking. If an LPG vehicle has been stored for a prolonged
period the storage room should be thoroughly ventilated before putting the
vehicle or its electrical systems into operation.
– The Industrial and Commercial Association and the responsible Trade
Supervisory Office must be informed immediately of any accidents which
occur in connection with gas cylinders or the liquified gas system. Dama-
ged components must be kept until the investigation has been concluded.
In storage rooms and in repair workshops
– The storage of power gas and liquefied-gas cylinders must be effected in
accordance with the stipulations of TRF 69 (Technical Regulations for
Liquefied Gas).
– LPG motor vehicles must not be stored in the same room with generator
vehicles.
– The cylinder and main shut-off valves should be closed immediately after
putting the motor vehicle into storage.
– The terms of the relevant legislation on garages and the relevant state
building regulations apply to the location and nature of the storage places
for fuel gas motor vehicles.
– The gas cylinders should be stored in special areas which are separate
from the storage rooms. Refer to “Handling and Storage of Filled Tanks” of
the Technical Principles of the “Statutory Regulation on Pressure Gas”.
– The electrical hand lamps which are used in these places must have a
closed, sealed globe and a rigid basket guard.
– When carrying out work in repair workshops the cylinder and main shut-off
valves should be closed and the fuel gas cylinders protected against heat.
Before interrupting or ending work a responsible person should check
whether all valves, in particular cylinder valves, are closed. Work involving
the use of naked flames, in particular welding and cutting work, must not
be carried out in the vicinity of fuel gas cylinders. Fuel gas cylinders must
not be stored in the workshops, even if they are empty.
– The storage rooms and workshops must be well ventilated. It is important
to remember that fuel gases are heavier than air. They concentrate on the
ground, in repair pits and other floor recesses and may form explosive
gas-air mixtures.
