Prior to start/safety test
Driving
Stop
 Release the accelerator pedal or drive
backwards for a moment, the machine
brakes automatically and stops.
Only use the brake pedal if the appliance 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
emergency brake while the appliance is not
moving, not as an operational brake.

몇 Warning
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.
몇 Warning
Risk of damage! Ensure that the vehicle
does not get stuck up.
The following safety tests must be conducted prior to each operation:
 Danger
Risk of accidents, injuries. If one point of
the safety check is not fullfilled, the appliance must not be taken into operation, but
must be repaired.
Safety check
Perform the safety check while the ignition
is switched on (position 1).
 With released parking brake: Release
accelerator pedal, switch off work hydraulics Main PTO - the motor must not
start when turning the ignition key (position 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
Daily maintenance tasks
Carry out the daily maintenance tasks (see
section "Maintenance and Care").
Operation
 Danger
Danger of crushing. Make sure that no persons are present near the arm hinges.
Danger of burns, crushing. Only use the
appliance if all casing parts have been attached.
Caution
Risk of damage by overheating of the power transmission and the brake. Only use the
brake pedal during travel, if the appliance
does not stop when the accelerator pedal is
released or briefly activated.
Danger of damage due to lack of lubrication. If the oil pressure warning lamp lights
up during operation, switch the engine off
immediately and remediate the malfunction.
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 lower than the position of the wheels (for
sweepers).

Release parking brake
 Press the brake pedal all the way.
 Turn the lock toward the rear.
 Release the brake pedal.
Start the engine
 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.
 With low exterior temperatures, turn the
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 power 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.
Driving
 Raise the working machine.
 Raise the suction opening and the sidebrushes (for sweepers).

Driving on public roads
When driving on public roads for transport
purposes (not when cleaning public roads),
the transport lock must be engaged. This
prevents idadvertent movement of the work
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.
During sweeping operation
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 continue to operate the sweeping machine in the
same position.
Note
To achieve an optimum cleaning result, 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 inclination of the 3rd side
brush (option).
Inclining the 3rd side brush will facilitate
the cleaning/sweeping of uneven surfaces (such as gutters).
Deflect large objects
Medium-sized objects (such as drink cans)
can be suctioned up by the appliance.
Large objects (such as branches) can be
deflected to the side by a brief reversal of
the side brush rotation direction.
 Pull lever A shortly towards the back.
The direction of rotation of the side
brush changes.
Restrict brush immersion depth
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.

Maintenance Works
General notes on safety
 Danger
Risk to life
When carrying out repairs, remove the vehicle from the danger zone of passing traffic and wear reflective clothing.
 Danger
Risk of injury due to engine overrun. Once
the engine has been switched off, wait for 5
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 maintenance tasks, tilt the waste container fully
upward and lower the brush system/attachment to remove the pressure from the hydraulic system.
Risk of injury due to inadvertently lowering
waste container. Prior to working underneath the waste container, move the waste
container all the way into the emptying position. (for sweepers).
Risk of injury due to inadvertently lowering
waste container. Only perform work on the
turbine while the waste container is completely lifted (for sweepers).
몇 Warning
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. Protect the ground and dispose of used oil in
an environmentally-clean manner.
Preparation
 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.
 Turn ignition key to "STOP" and remove
it.
 Lock parking brake.

Safety notes regarding the batteries
Please observe the following warning notes
when handling batteries:
Observe the directions on the
battery, in the instructions for
use and in the vehicle operating instructions!
Wear an eye shield!
Keep away children from acid
and batteries!
Risk of explosion!
Fire, sparks, open light, and
smoking not allowed!
Danger of causticization!
First aid!
Warning note!
Disposal!
Do not throw the battery in the
dustbin!
 Danger
Follow accident prevention regulations as
well as DIN VDE 0510, VDE 0105 T.1.
Risk of explosion! Do not put tools or similar
on the battery, i.e. on the terminal poles
and cell connectors.
Risk of injury! Ensure that wounds never come
into contact with lead. Always clean your hands
after having worked with batteries.
Risk of fire and explosion!
– Smoking and naked flames must be
strictly avoided.
– Rooms where batteries are charged
must have good ventilation because
highly explosive gas is emitted during
charging.
Danger of causticization!
– Rinse thoroughly with lots of clear water
if acid gets into the eye or comes in contact with the skin.
– Then consult a doctor immediately.
– Wash off the acid If it comes in contact
with the clothes.
– Change clothing.
