Safety
Operating instructions
Operating instructions
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 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
Operating instructions
Operating instructions
• 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.
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.
