Safety
General notes on safety
• Observe your national regulations on safety and
health protection.
• Do not allow children under 16 to use the vehicle.
• When using the public highway, respect the highway
code.
• Do not allow anyone to stand around where they might
get hurt.
• Do not run the engine in enclosed spaces.
• Exercise extreme caution when handling fuels - there
is a high risk of fire.
• Exercise caution when handling brake fluid and
battery acid (poisonous and corrosive).
• To prevent the danger of fire, keep the vehicle and
implements clean.
• Observe the warning notices and symbols on your
vehicle.
• In case of an emergency stop with a defective
inching pedal or defective traction hydraulics, the
vehicle can only be brought to a halt by turning the
ignition to 0 and applying the service brake.
Work clothing
• Only wear close-fitting clothing when working with the
vehicle.
• If necessary, wear suitable headwear to keep loose
hairs and pigtails from being caught in rotating parts.
• Do not wear any jewellery and similar objects, eg
rings, when working with the vehicle.
Safety notes for later installations
The vehicle has electronic components whose proper func-
tioning can be influenced by electromagnetic emissions from
other equipment. These influences can endanger persons if
the following safety precautions are not observed.
• Have the equipment installed by an authorized work-
shop only.
• Before the installation of electric or electronic equip-
ment connected to the vehicle’s electrical system,
check if these installations can interfere with the
vehicle’s electronic system or other system compo-
nents.
C 4.74
Operating instructions
12 149 443
Operating instructions
• The installed equipment must conform to the applica-
ble EMC directive 89/336/EU and carry the CE
symbol.
• If you must install a mobile communications system
(or have it installed) (eg radio, mobile phone), the
following requirements must be met:
- Only approved equipment (ie with type approval) may
be installed.
- The equipment must be installed firmly.
- The operation of portable or mobile equipment inside
the vehicle is only allowed if connected to a perma-
nently installed external antenna.
- The transmitting section must be installed away from
the vehicle’s electronic system.
- When installing the antenna, install it properly and
with a good connection to vehicle ground.
- Do not exceed the maximum permissible current
rating of the wiring according to the installation in-
structions of the equipment manufacturer.
- When doing electric welding, disconnect all cable
plugs from the electronic units.
Safety precautions for handling fuels and oils
Gear oil, engine oil, diesel fuel
Do not eat, drink or smoke when handling these
fuels and oils. Prolonged intensive contact may
cause degreasing and irritation of the skin. Wash
skin with water and soap, use skin care prod-
ucts. If required, wear personal protective gear.
Change soaked clothes and shoes immediately.
If vapour or mist was inhaled, breathe fresh air.
Consult a doctor if the complaint persists. After
contact with the eyes, rinse the eyes thoroughly
with water (at least 10 minutes), then consult
an eye doctor. If swallowed, do not force to vomit,
but consult a doctor. Danger of slipping on the
spilled product, particularly in connection with
water.
Oils can contaminate water. Always keep them
in approved containers. Avoid spilling oils. Re-
move spilled fluids immediately with an oil bind-
ing agent and discard in accordance with laws
and regulations. Discard drained fluids as speci-
fied. Observe applicable laws and regulations.
Oils are inflammable. Do not let them come in
contact with hot engine parts as fire can result.
Operating instructions
149 443 13
C 4.74 Operating instructions
Hydraulic oil, brake fluid
During operation, these fluids are pressurized
and pose a health hazard. Do not spill these
fluids. Remove any spilled fluids immediately
with oil binding agent and discard them. Dis-
card drained fluids as specified. Observe appli-
cable laws and regulations. Do not allow them
to come in contact with hot engine parts. Dan-
ger of fire!
Avoid contact with the skin. Avoid the inhala-
tion of spray fog. The penetration of pressu-
rized fluids into the skin is particularly danger-
ous if these fluids are under high pressure and
escape from the hydraulic system through
leaks. Seek medical aid at once in case of such
injuries.
If injuries can not be excluded, use suitable
personal protector (for example, protective
gloves, glasses and skin protection and skin
care creams).
Battery acid
Battery acid contains dissolved sulphuric
acid. This acid is poisonous and caustic. When
working with battery acid, always wear pro-
tective clothing and eye protectors. Do not
allow acid to contact the clothing, skin or eyes;
in case of contact wash immediately with
ample clean water. In case of personal inju-
ries, consult a doctor at once. Neutralize
spilled battery acid immediately.
Discard drained fluids as specified. Observe
applicable laws and regulations.
Emissions
Exhaust gases
During operation, the engine emits exhaust
gas into the environment. The exhaust gas
mainly consists of water vapour, carbon di-
oxide (CO2), carbon monoxide (CO), hydro-
carbon (CH), nitrogen oxide (NOX) and soot.
The components CO, CH and NOX are poi-
sonous or hazardous to health and should
not be inhaled in high concentrations. Soot is
considered to be a carcinogenic material.
C 4.74
Operating instructions
14 149 443
Operating instructions
Particularly the particles contained in the
exhaust gas can cause cancer. For this rea-
son the engine should not be operated in en-
closed spaces.
Heat
The exhaust gases are very hot and can ig-
nite inflammable material. The exhaust gas
pipe should therefore be kept away from ig-
nitable materials.
Battery
During charging, the battery produces a mix-
ture of oxygen and hydrogen (detonating gas).
This mixture of gases is explosive and must
not be ignited. The risk of explosion can be
avoided with the appropriate ventilation and
keeping naked flames away. Observe the
safety rules for handling the battery.

Check the trailer hitch (option) if required
- Check the trailer hitch for proper condition and opera-
tion. Carry out the check according to the instructions
in the section “Operating the trailer hitch“.
Check the tire inflation pressure
NOTE
Your vehicle can be equipped with different types
of tires. The specified inflation pressure for your
tires is given in the table entitled “Tires“ in the
technical data section.
- Check the inflation pressure at all four tires. All tires must
have the same pressure. The rolling resistance increases
if the pressure is too low. This causes an increase in fuel
consumption and tire wear, the driving characteristics
become poorer.
DANGER
If the inflation pressure is too high, the tires
can explode.
- The tires should not be damaged or worn.
- Have damaged tires replaced without delay. Due to the
longer braking distance the risk of an accident is in-
creased.

the cab doors closed.
• Always adjust your speed to the driving conditions
and the load you are carrying.
• Never drive downhill without having the vehicle in gear
or with the engine stopped.
• Before driving, check that no-one is standing in the
immediate vicinity of the vehicle.
• The driving behaviour of the vehicle is strongly
affected by the weight and swing range of the imple-
ments, trailers and, if fitted, ballasting. Therefore
drive slowly with heavy equipment and take the longer
braking distance into consideration.
• When following a curve with a trailer or other implements,
do not forget to take the added length and drag into
consideration.
DANGER
Any parts of the implements posing a traffic
hazard must be covered before driving or
identified with warning signs.
• Switch off the differential lock in curves.
• When driving on slopes, always drive straight downhill
if possible; if you have to turn, turn only uphill.
• On steep slopes you can improve traction by activat-
ing the differential lock.
• Drive across slopes only in accordance with the notes
at the end of this chapter.

Driving on slopes
DANGER
Driving on slopes is dangerous as the vehi-
cle can tip over if the centre of gravity ex-
ceeds the tip-over limit on an extreme slope.
The following factors reduce the hazard:
- small or no load
- low driving speed
- low gradient
- low tire inflation pressure
NOTE
The driving comfort and the traction of the
vehicle can be improved by reducing the in-
flation pressure.
- large track width
- level, non-bumpy terrain
When turning on slopes we recommend proceeding as
shown in the drawing on the right.

Operating the implements
We have tested and approved a large number of possible
implements for use with this vehicle. Only implements with
the CE symbol may be used. We recommend contacting
our customer service before installing special equipment.
Possible implements
For example for:
vineyards and orchards
agriculture
mowers
snow fighting equipment
and other street cleaning equipment.
Safety instructions for handling implements
The vehicle must be parked safely before the installation of
implements.
It must be secured against rolling, for example, with the park-
ing brake or, if required, with chocks.
DANGER
Be careful when attaching implements: risk of
injury by pinching and shearing parts.
DANGER
No persons are allowed to stand between the
vehicle and implement when the vehicle is not
secured against rolling.
For driving on roads the implement must be
lifted and secured against lowering.
Observe the applicable safety regulations for
your implement. Observe the operating in-
structions and the safety rules for your im-
plement.
DANGER
During work breaks, the implement must al-
ways be lowered to the ground in order to
relieve the hydraulic cylinders. Accidents can
occur if the lowering is uncontrolled, for ex-
ample, due to damage or accidental move-
ment of the control levers.
DANGER

Additional information on implements
Do not exceed the permissible total weight,
the permissible axle loads and tire carrying
capacities of the vehicle when installing im-
plements on the front and rear 3-point lift. The
front axle of the vehicle must always be loaded
with at least 20 % of the vehicle’s kerb weight.
Before purchasing equipment, make sure these
conditions are met by performing the following
calculations or by weighing the vehicle-equip-
ment combinations.
Determining the total weight, axle loads and tire carry-
ing capacity including the minimum ballasting.
For their calculation you need the following data:
TL(kg) Kerb weight of the vehicle 1)
TV(kg) Front axle load of the empty vehicle 1)
TH(kg) Rear axle load of the empty vehicle 1)
GH(kg) Total weight of
rear implement/rear ballast 2)
GV(kg) Total weight of
front implement/front ballast 2)
a (m) Clearance between centre of gravity
of front implement/front ballast and
centre of front axle 2) 3)
b (m) Vehicle wheelbase 1) 3)
c (m) Distance between centre of rear axle
and centre of lower link ball 1) 3)
d (m) Distance between centre of
lower link ball and centre of gravity of
rear implement/rear ballast 2)

Connecting hydraulic lines
ATTENTION
The hydraulic couplings on the vehicle must
not carry any pressure before the connection
is made. The couplings on the vehicle and
the hydraulic hoses must be clean.
NOTE
Each implement has different functions and
hydraulic lines to the control unit. Observe
the operating instructions supplied with your
implement and make yourself familiar with
the functions and colour codes.
- Open the protective caps of the hydraulic couplings (1).
- Attach the colour coded hydraulic hoses (2) of the
implement to the hydraulic couplings of the same
colour on the vehicle.
ATTENTION
The hydraulic male couplings fit on each cou-
pling and can therefore be connected incorrectly.
With the connection you decide which func-
tion/movement of the implement is actually
to be performed with the control lever as-
signed to the coupling.
DANGER
If you are not sure about the functions, de-
termine them by making trials at a safe place.

C 4.74 General remarks on maintenance
Handling fuels and lubricants
• Fuels and oils must always be handled properly and as
specified by the manufacturer.
• Fuels and oils may only be stored in approved contain-
ers at specified places of storage. They can be inflam-
mable, therefore do not allow them to come in contact
with hot objects or with naked flames.
• Exercise caution when handling fuels - increased dan-
ger of fire. Do not fill any fuels in the vicinity of naked
flames, ignition sparks or hot engine parts. No smoking
when refuelling!
• Before refuelling, shut off the engine and remove the
ignition key. Do not refuel within enclosed spaces. Do
not spill fuels! (use suitable filling aids).
• Exercise caution when handling brake fluid and battery
acid (poisonous and corrosive).
• Only use clean vessels when filling fuel and oil.
• When using fuels, oils and cleaners, follow the safety
and disposal instructions of the manufacturer.
• Always avoid spilling. Eliminate spilled brake fluid
immediately with a suitable binding agent and discard
as specified by regulations.
• Oils, fuels, batteries, brake fluid and filters must be
disposed of separately and as specified by regulations.
• Before beginning lubrication, changing filter or opening
the hydraulic system, clean the area surrounding the
affected part carefully.
• Replaced parts must be discarded in a way friendly to
the environment.
• Observe all local and national laws and regulations.
CAUTION
The penetration of hydraulic oil under pres-
sure into the skin, eg through leaks, is dan-
gerous. If such injuries occur, seek medical
aid.
Safety notes for maintenance
Observe the notes in these maintenance instructions and
the general applicable safety and accident prevention rules!
• Do not allow anyone to stand around where they might
get hurt!
• When starting the engine, the traction and implement
drive must be shut off!
• Start the engine only from the driver’s station. Do not
start the engine by short circuiting the starter terminals,
as the machine could start moving immediately.

General remarks on maintenance
• Do not run engine in enclosed spaces! Danger of
poisoning!
• To prevent the danger of fire, keep the vehicle and
implements clean!
• When leaving the vehicle, secure it against rolling and
unauthorized use (parking brake, chocks), stop the
engine, remove the ignition key and, if required, lock the
cabin!
• Never leave the vehicle unattended while the engine is
running!
• If external power loads are connected, eg equipment
with solenoid valves, protect them with diodes against
back currents. If not, the traction electronics could be
affected.
• Operate the equipment only if all guards are installed
and in position.
• Install and remove the articulated shaft only with the
engine stationary.
• When working with the PTO shaft, no-one should be
standing in the area of the rotating PTO and articulated
shaft.
• The guards for the articulated shaft and the PTO shaft
must be installed as specified.
• When the articulated shaft is removed, refit the protec-
tive cap on the PTO shaft.
• Do not perform any welding, cutting and grinding work
on carrying and other safety-relevant parts such as
vehicle frame, axles, trailer hitch, etc.
• When doing electric welding, disconnect all connector
plugs from the electronic units.
• The mounting of tires requires sufficient knowledge and
special mounting tools.
• Only use genuine HOLDER replacement parts! Use the
parts in the list of maintenance parts in the chapter
entitled “Maintenance data“.
• The vehicle and the implement must be checked for
road worthiness and operating safety before taking it
into operation and after servicing or repairs.
