¾The folding boom must only be operated when
there are no persons inside the slewing range!
¾Parts actuated by external forces (e.g. hydrauli-
cally) have crushing and shearing points!
¾When working on the crop protection sprayer
secure the machine with wheel chocks
against rolling away!
¾Match your travel mode in such a way, that
you will at any time be able to securely con-
trol the tractor with hitched up or unhitched
machine at any time.
Be aware of your own abilities, account for the
road, tra󰘲c, sight and weather conditions, the
driving characteristics of the tractor and the
in󰘱uences of the mounted or towed machine.
1.6.2 Coupling and uncoupling
the machine
¾Only couple the machine to such tractors and
transport it with tractors suitable for this purpose.
¾Couple the machine properly to the speci󰘰ed
devices!
¾By coupling the machine to the front and/or
rear of a tractor you must not exceed:
• the permissible total weight of the tractor
• the permissible tractor axle loads
• the permissible tyre load bearing capacities
of the tractor tyres
¾Secure both tractor and machine against
unintended rolling away before coupling or
uncoupling the machine!
¾Persons are not allowed to stand between
the machine to be hitched up and the trac-
tor, while the tractor is moving towards the
machine!
Possibly assisting persons must stay besides
the vehicles and may only step between the
vehicles when these are at standstill.
¾Lock the operating lever for the tractor hydrau-
lics in a position in which accidental lifting or
lowering is ruled out!
¾When hitching and unhitching machines move
the supporting devices (if present) to the cor-
responding position (stability).
16

¾When operating supporting devices there is
danger of injuring at crushing and shearing
points!
¾Be particularly cautious when coupling and
uncoupling the machine to or from the tractor!
There are crushing and shearing points at the
coupling point between tractor and machine!
¾Persons are not permitted to stand between
tractor and machine when the hydraulic sys-
tem is operated!
¾Coupled supply lines
• must easily follow all movements when
cornering without any tension, buckling or
cha󰘰ng.
• must not rub against other parts.
¾Triggering ropes for quick release couplings
must hang down loosely and should not trig-
ger any action when in lowest position!
¾Always park unhitched machines in a stable
position!
¾Never unhitch with an empty tank and un-
folded folding boom!
Negative drawbar load can cause the machine
to tip over!
1.6.3 Working with the machine
¾Become familiar with all equipment and con-
trol elements of the machine as well as their
functions before starting work.
¾Wear tight 󰘰tting clothes! Loose clothes in-
crease the danger of being caught or pulled
in by rotating or moveable components.
¾Only start operation of the machine, if all pro-
tective features have been installed and are
fully functional in protective position!
¾Observe the maximum payload of the mount-
ed / hitched up machine and the permissible
axle and drawbar loads of the tractor. If nec-
essary drive with the tank only partly 󰘰lled.
¾Persons are not permitted to stay inside the
working range of the machine!
¾Persons are not permitted to stay inside the
turning and slewing range of the machine!
¾Use accessing aids and steps only at stand-
still. During operation it is not permitted to ride
on the machine as a passenger!
¾Never climb onto a ,moving machine!
¾Parts actuated by external forces (e.g. hydrau-
lically) have crushing and shearing points!
¾Power operated machine parts must only be
actuated if persons keep a su󰘲cient safety
distances to the machine!
¾Secure the tractor against unintended starting
and accidental rolling before leaving it.
To do so
• lower the machine to the ground
• apply the parking brake
• shut down the tractor engine
• Pull out the ignition key

to climb onto the machine. You could fall and
be seriously injured.
17

1.6.5 Transporting the machine
¾When driving on public roads comply with the
corresponding national road tra󰘲c regula-
tions!
¾Before starting transport travels check the
correct connection of all supply lines:
• the light system for damage, function and
cleanliness
• the brake and hydraulic system for appar-
ent faults
• whether the parking brake is fully released
• the function of the brake system
¾Always ensure su󰘲cient steering and braking
capacity of the tractor!
Machines attached to or towed by a tractor or
front or tail weights a󰘯ect the driving proper-
ties as well as the steering and braking ability
of the tractor.
¾Observe the maximum payload of the mount-
ed / hitched up machine and the permissible
axle and drawbar loads of the tractor!
¾The tractor must secure the prescribed brak-
ing deceleration for the load carrying tractor/
machine combination!
¾Check the braking e󰘯ect before setting o󰘯!
¾Consider the width and centrifugal mass of
the machine when cornering with the machine
attached or hitched up!
¾Before starting transport travels move all sle-
wable machine parts into transport position!
¾Before starting transport travels lock all sle-
wable machine parts in transport position to
prevent endangering position changes.
Use the dedicated transport locks for this
purpose!
¾Before starting transport travels lock the con-
trol levers for the hydraulic system to prevent
accidental lifting or lowering of the attached
or hitched up machine!
¾Before starting transport travels check wheth-
er the necessary transport equipment has
been correctly mounted to the machine, such
as e.g. lighting, warning signs and protective
features!
¾Match the travel speed to the prevailing con-
ditions!
¾Shift to a lower gear before driving downhill!
¾Always switch o󰘯 single wheel braking (lock
the pedals!) before starting transport travel!
¾Pay attention to the notes in chapter Transport
travel.
1.6.6 Hydraulic system
WARNING
¾The hydraulic system is under high pressure!
¾Ensure correct connection of the hydraulic
hoses!
¾When connecting hydraulic hoses make sure
that the hydraulic system has been depres-
surized on both tractor and machine side!
¾Blocking actuators on the tractor, which serve
the purpose of directly executing hydraulic or
electric movements of components, such as
e.g. folding, slewing and pushing processes,
is prohibited.
The corresponding movements must auto-
matically stop once you release the corre-
sponding actuator. This does not apply for
equipment which
• are continuous or
• automatically controlled or
• require a 󰘱oating or pressure position be-
cause of their function
¾Before starting work in the hydraulic system
• lower the machine to the ground
• depressurize the hydraulic system
• shut down the tractor engine
• apply the parking brake.
• pull out the ignition key
18

¾Pressure accumulator
Depending on the equipment of the machine,
the hydraulic system may have a pressure ac-
cumulator installed. Do not open or work (weld-
ing, drilling) on the pressure accumulator. Even
after being emptied, the tank is still preloaded
by gas pressure. Always depressurize the
pressure accumulator before starting work on
the hydraulic system. The pressure gauge (if
present) should not indicate any pressure. The
pressure in the pressure gauge must drop to 0
bar. Only then may work be carried out on the
hydraulic system.
¾Have the hydraulic hoses inspected by an ex-
pert under occupational safety related aspects
at least once every year!
¾Replace hydraulic hoses if damaged or exces-
sively aged! Use only genuine hydraulic hoses
from HORSCH LEEB AS!
¾The utilization period of hydraulic hoses
should not exceed six years, including a pos-
sible storage time of maximum two years.
Even if properly stored and under permissible
stress, hoses and hose connections are sub-
ject to natural ageing, which limits their shelf
life and utilization period. Deviating from this,
the utilization period can also be determined
on the basis of empirical values, particularly
under due consideration of the endangering
potential. For hoses and hose lines made of
thermoplastics other guide values may be
decisive.
¾Never try to seal o󰘯 leaking hydraulic hoses
with your hands or 󰘰ngers. Fluids (hydraulic
oil) escaping under pressure can penetrate
the skin and enter into the body causing se-
vere injury! If injured by hydraulic oil, consult
a doctor immediately! Danger of infection!
¾Due to the possible danger of severe infec-
tions, one must use appropriate auxiliary
means when looking for leakages!
¾Power sockets and connectors (electric,
pneumatic) should be identi󰘰ed by colour to
rule out operating errors.
¾In order to avoid accidents caused by unde-
sired hydraulic movements or hydraulic move-
ments triggered by other persons (children,
passenger), the control units on the tractor
must be secured and locked when not in use
or in transport position.
1.6.7 Electrical system
Always disconnect the battery (negative pole)
before starting work in the electric system!
¾Use only the speci󰘰ed fuses! The use of too
strong fuses will destroy the electric system.
Fire hazard!
¾Make sure that the battery is correctly con-
nected. Connect the plus pole 󰘰rst and the
minus pole after. When disconnecting discon-
nect the negative pole 󰘰rst and the positive
pole after!
¾Always cover the positive battery pole with the
dedicated covering. Danger of explosion in
case of short-circuit to ground!
¾Avoid sparking and naked 󰘱ames in the vicin-
ity of the battery! Danger of explosion!
¾The machine can be equipped with electronic
components and parts, the function of which
can be a󰘯ected by the transmission of electro-
magnetic waves from other equipment. Such
in󰘱uences can lead to the endangerment of
persons, if the following safety notes are not
complied with.
In case of a subsequent installation of electric
appliances and/or components on the ma-
chine, with connection to the on-board power
supply, the user in his own responsibility must
check whether this installation will cause
interferences in the vehicle electronics or in
other components.
Make sure that the subsequently installed
electric and electronic components are
in accordance with the valid issue of the
EMC directive 2014/30/EC and are identi󰘰ed
with the CE-sign.

1.6.8 Towed machines
¾Pay attention to the permissible combinations
of hitching device on the tractor and drawbar
hitch on the machine!
Couple only permissible vehicle combinations
(tractor and towed machine).
¾In case of single-axle machines pay attention
to the maximum permissible drawbar load of
the tractor on the hitching device!
¾Always ensure su󰘲cient steering and braking
capacity of the tractor!
Machines mounted to or towed by a tractor
a󰘯ect the travel behaviour as well as the steer-
ing and braking ability of the tractor, especially
single-axle machines with drawbar load ap-
plied to the tractor!
¾For drawbars with drawbar load, the height
of the drawbar must only be adjusted in a
specialist workshop!
1.6.9 Brake system
¾Adjustment and repair work on the brake
system must only be carried out in expert
workshops or established brake service
workshops.
¾Immediately stop the tractor in case of brake
system malfunctions.
Have the malfunction remedied immediately.
¾The brake system must be thoroughly
checked at regular intervals.
¾Securely park the machine before starting
work in the brake system. Secure the machine
against unintended lowering and rolling away
(wheel chocks)!
¾Be extra careful when performing welding,
󰘱ame cutting or drilling work near brake lines!
¾After setup and repair work on the brake sys-
tem you must generally carry out a brake test!
¾Pay attention to the corresponding regulations
(France) when changing the hydraulic oil!
¾Only use the speci󰘰ed hydraulic oils (France)
when topping up or changing the hydraulic oil.
1.6.10 Pneumatic brake system
¾Only drive o󰘯 with the hitched up machine af-
ter the operating pressure required to release
the brake has been reached (pressure gauge
on tractor).
¾Before coupling the machine clean the seal
rings on the coupling heads of the supply and
brake line from possible contamination!
¾Close the coupling heads on the tractor before
driving without machine!
¾Close the coupling heads of supply and brake
lines and hook these into the brackets pro-
vided for this purpose!
¾Drain the air vessel daily!
¾The speci󰘰ed settings on the brake valves
must not be changed!
¾Change the air vessel if it is loose in the ten-
sion straps, if it is damaged, the type plate is
corroded, loose or missing.
1.6.11 Tyres
¾When working on the tyres make sure that the
machine has been parked safely and properly
secured against rolling away and accidental
lowering (parking brake, wheel chocks).
¾The assembly of wheels and tyres requires
profound knowledge and the use of proper
assembly tools!
¾Repair work on tyres and wheels must only be
carried out by specialists and only with the ap-
propriate assembly tools for this kind of work!
¾Check the air pressure regularly! Pay attention
to the speci󰘰ed air pressure!
¾Check the wheel nuts regularly and retighten
all fastening screws and nuts as speci󰘰ed by
HORSCH LEEB AS GmbH! Failing to do so
can lead to loosing wheels and thus to the
machine tipping over.
