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 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.
149 443 11

C 4.74
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.
12 149 443
C 4.74
Hydraulic oil, brake fluid
Operating instructions
Operating instructions
Battery acid
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).
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.
149 443 13
Operating instructions
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.

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.
Taking into operation
Bild_C230
- 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.

Operation
Before starting to drive
Operating instructions
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 59
• 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

Additional information on implements
Do not exceed the permissible total weight,
the permissible axle loads and tire carrying
capacities of the vehicle when installing implements 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-equipment combinations.
Determining the total weight, axle loads and tire carrying capacity including the minimum ballasting.
For their calculation you need the following data:
