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 functioning 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 workshop only.
• Before the installation of electric or electronic equipment connected to the vehicle’s electrical system,
check if these installations can interfere with the
vehicle’s electronic system or other system components.

The installed equipment must conform to the applicable 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 permanently 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 instructions 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 products. 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. Remove spilled fluids immediately with an oil binding agent and discard in accordance with laws
and regulations. Discard drained fluids as specified. Observe applicable laws and regulations.
Oils are inflammable. Do not let them come in
contact with hot engine parts as fire can result.
149 443
Operating instructions
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. Discard drained fluids as specified. Observe applicable laws and regulations. Do not allow them
to come in contact with hot engine parts. Danger of fire!
Avoid contact with the skin. Avoid the inhalation of spray fog. The penetration of pressurized fluids into the skin is particularly dangerous 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).
149 443
Battery acid
Battery acid contains dissolved sulphuric
acid. This acid is poisonous and caustic. When
working with battery acid, always wear protective 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 injuries, 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 dioxide (CO2), carbon monoxide (CO), hydrocarbon (CH), nitrogen oxide (NOX) and soot.
The components CO, CH and NOX are poisonous or hazardous to health and should
not be inhaled in high concentrations. Soot is
considered to be a carcinogenic material.
13
Operating instructions
C 4.74
Operating instructions
Particularly the particles contained in the
exhaust gas can cause cancer. For this reason the engine should not be operated in enclosed spaces.
Heat
The exhaust gases are very hot and can ignite inflammable material. The exhaust gas
pipe should therefore be kept away from ignitable materials.
Battery
During charging, the battery produces a mixture 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.

Taking into operation
Check the trailer hitch (option) if required
-
Check the trailer hitch for proper condition and operation. 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.
Bild_C230
-
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 increased.

Before starting to drive
When driving on public highways, observe the rules and
regulations of the highway code.
•
Driving safety rules
•
•
•
•
•
Drive the vehicle only from the driver’s station with
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 implements, trailers and, if fitted, ballasting. Therefore
drive slowly with heavy equipment and take the longer
braking distance into consideration.
149 443
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 activating the differential lock.
Drive across slopes only in accordance with the notes
at the end of this chapter.

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 instructions and the safety rules for your implement.
DANGER
During work breaks, the implement must always be lowered to the ground in order to
relieve the hydraulic cylinders. Accidents can
occur if the lowering is uncontrolled, for example, due to damage or accidental movement of the control levers.

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 containers at specified places of storage. They can be inflammable, therefore do not allow them to come in contact
with hot objects or with naked flames.
Exercise caution when handling fuels - increased danger 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.
149 443
•
•
•
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 pressure into the skin, eg through leaks, is dangerous. 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!

Operating instructions
Laying up
If the vehicle is not going to be in service for over 2 months,
for example for operational reasons, it must be placed in a
well-ventilated, clean and dry room and the following measures must be carried out.
-
Clean the vehicle thoroughly.
Check the hydraulic oil levels, topping up oil if necessary
Cover all blank mechanical components with a thin
film of oil or grease.
Grease the vehicle.
Check the condition and acid density of the battery;
cover the battery terminals with non-acidic grease.
(Observe the instructions of the battery manufacturer.)
Remove the battery and store in a frost-free, dry
room.
Engine preservation
-
Clean the engine.
Run the engine warm.
Drain the engine oil and refill with anti-corrosion oil.
Drain the fuel and fill up the fuel tank with a mixture of
90 % diesel fuel and 10 % anti-corrosion oil. Mixing
ratio of diesel fuel 90 %, anti-corrosion oil 10 %.
Run the engine for 10 minutes.
Shut off the engine.
149 443
-
Crank the engine a few times by hand.
Seal the intake and exhaust openings.
ATTENTION
The vehicle must be blocked up so that all
the wheels are off the ground. This will prevent a permanent deformation of the tires.
NOTE
Do not use plastic foil to cover the vehicle as
this enhances the formation and collection
of condensate water.
Putting the vehicle back in service after lay-up
If the vehicle was taken out of service for over six months,
it must be inspected carefully before being put back in service. The inspection should, similar to the safety inspection,
also cover all safety relevant components of the vehicle.
-
Clean the vehicle thoroughly.
Grease the vehicle.
Check the condition and acid density of the battery,
recharge it if necessary.

If the vehicle is to be laid up for a longer period, please
contact your HOLDER Service for further measures.
ATTENTION
Observe the instructions for handling fuels
and lubricants.
See the section „Change the engine oil“ on how to proceed
further.
-
Check the hydraulic oil for condensed water, change
the oil if necessary.
Perform the checks and services as for before taking
into service.
Fill the fuel tank.
Change the brake fluid.
Take the vehicle into operation.
When taking into the vehicle into service, particularly check:
- Variable-displacement pumps and wheel motors for
leaks.
