The following safety tests must be conduct-
ed prior to each operation:
Danger
Risk of accidents, injuries. If one point of
the safety check is not fullfilled, the appli-
ance must not be taken into operation, but
must be repaired.
Perform the safety check while the ignition
is switched on (position 1).
Withreleasedparkingbrake:Release
accelerator pedal, switch off work hy-
draulics Main PTO - the motor must not
start when turning the ignition key (posi-
tion 2).
With actuated brake pedal: Switch on
work hydraulics Main PTO - the motor
must not start when turning the ignition
key (position 2).
With running motor: Switch on work
hydraulics Main PTO, relieve driver
seat - the work hydraulics Main PTO
must switch off
Carry out the daily maintenance tasks (see
section "Maintenance and Care").
Danger
Danger of crushing. Make sure that no per-
sons are present near the arm hinges.
Danger of burns, crushing. Only use the
appliance if all casing parts have been at-
tached.
Caution
Risk of damage by overheating of the pow-
ertransmissionandthebrake.Onlyusethe
brake pedal during travel, if the appliance
doesnotstopwhen the acceleratorpedalis
released or briefly activated.
Danger of damage due to lack of lubrica-
tion. If the oil pressure warning lamp lights
up during operation, switch the engine off
immediately and remediate the malfunc-
tion.
Risk of damage due to overheated engine
or overheated hydraulic oil. If the warning
lamps for engine temperature or hydraulic
oil temperature lights up, set the engine
speed to idle (do not turn the engine off)
and perform the measures in the Chapter
"Malfunctions".
Danger of damage to the hydraulic hoses
of the sweeping unit. Do not lower the
brush to the ground or the platform any low-
er than the position of the wheels (for
sweepers).

Press the brake pedal all the way.
Turn the lock toward the rear.
Release the brake pedal.
Remove your foot from the accelerator
pedal.
Set engine speed to MIN position.
Press the brake pedal all the way down.
The indicator lamp for the emergency
brake must be illuminated.
Withlowexterior temperatures,turnthe
ignition key to pre-heating setting for
about 3 seconds.
Turn the ignition key to "Start engine"
and hold it there until the engine starts
up.
Release the ignition key. The ignition
key turns to position "1", engine on.
Release the brake pedal.
Caution
Risk of damage by overheating of the pow-
er transmission and the brake. Do not drive
appliance while brake is activated.
After a cold start, let the appliance
warm up while the engine speed is set
to MIN, so that the hydraulic oil can
reach operating temperature.
The pre-heating time depends on the
ambient temperature and can be read
from the diagram below.
Raise the working machine.
Raise the suction opening and the side-
brushes (for sweepers).
Set engine speed to ECO.
Press accelerator pedal down slowly.
Control the driving direction with the
steering wheel.
Release the accelerator pedal or drive
backwards for a moment, the machine
brakes automatically and stops.
Only use the brake pedal if the appli-
ance does not stop in spite of applying
the above measures.
Caution
Risk of damage to the drive system. Use
the brake only in emergencies and as an
emergencybrakewhile theapplianceisnot
moving, not as an operational brake.
몇Warning
Risk of damage! Raise the side-brushes
and the suction opening before overtaking
hurdles.
Hurdles up to 150 mm in height:
Bypass the hurdle slowly and carefully
at an angle of 45°.
Hurdles more than 150 mm in height:
Only drive over these obstacles using a
suitable ramp.
몇Warning
Risk of damage! Ensure that the vehicle
does not get stuck up.
When driving on public roads for transport
purposes(not whencleaningpublicroads),
the transport lock must be engaged. This
preventsidadvertentmovementofthework
units.
Move lever into the idle position.
Attach the transport lock with the pins
pointing downward and insert the pins
into the guide slots of the levers.
Caution
Do not sweep up packing strips, wire or
similar objects as this may choke up the
suction canal.
To avoid damaging the floor, do not contin-
ue to operate the sweeping machine in the
same position.
Note
Toachieve anoptimum cleaningresult, the
driving speed should be adjusted to take
specific situations into account.
During operation, the waste container
should be emptied at regular intervals.
Start the engine and let it warm up.
Set engine speed to ECO.
Adjust the side brush speed.

the side brush rotation direction.
Pull lever A shortly towards the back.
The direction of rotation of the side
brush changes.
If soft brushes are used, it may become
necessary to restrict their immersion depth
too prevent excessive deformation of the
bristles during the sweeping process.

there is nobody in the way, ask them to
move if somebody is around.
Danger of tipping. Empty waste container
only while the appliance is on stabile
ground, which is tilted neither to the rear
nor the side.

emptying on dumps or ramps.
Danger of accident! Use the emergency
brake when emptying the waste container.
Risk of injury! Switch off the suction turbine
before emptying the waste container.
Risk of injury! When emptying the waste
container, care should be taken to ensure
that no persons or animals are within its

regulations by customer service.
Danger
Risk to life
When carrying out repairs, remove the ve-
hicle from the danger zone of passing traf-
fic and wear reflective clothing.
Danger
Risk of injury due to engine overrun. Once
theengine hasbeen switchedoff, wait for5
seconds. Stay well clear of the working
area for this time.
Risk of injury if the machine is left running
in an unattended state. Remove the key
and disconnect the battery before working
on the appliance.
Do not point the high pressure jet towards
electrical components, tyres, radiator fins
and hydraulic hoses.
When cleaning the appliance with a high
pressure cleaner, adhere to the respective
safety instructions.
Maintenance on the hydraulic system must
only be carried out by trained personnel.
Danger
Risk of injury! While carrying out mainte-
nance tasks, tilt the waste container fully
upward and lower the brush system/attach-
ment to remove the pressure from the hy-
draulic system.
Risk of injury due to inadvertently lowering
waste container. Prior to working under-
neath the waste container, move the waste
container all the way into the emptying po-
sition. (for sweepers).
Risk of injury due to inadvertently lowering
waste container. Only perform work on the
turbine while the waste container is com-
pletely lifted (for sweepers).
몇Warning
Allow the machine sufficient time to cool
down before carrying out any maintenance
and repair work.
Do not touch any hot parts, such as the
drive motor and exhaust system.
Cooling water is hot.
Caution
Please do not release engine oil, fuel oil,
diesel and petrol into the environment. Pro-
tect the ground and dispose of used oil in
an environmentally-clean manner.
Park the machine on an even surface.
Lower the working equipment or side
brush, in order to do so, bring lever B to
the front.
Set engine speed to MIN position.
