other equipment. These influences can endanger persons if
the following notes on safety are not observed.

• Have the equipment installed by your service centre
only.

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

153 146 11

Operating Instructions

Operating instructions

C 9.92

Safety instructions for handling fuel, fluids
and lubricants

Gear oil, engine oil, diesel fuel

Do not eat, drink or smoke when handling
these fuel, fluids and lubricants. Prolonged
intensive contact may cause degreasing and
irritation of the skin. Wash the skin with water
and soap; use a skin care cream. If neces­sary, 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 fluids.
Remove spilled fluids immediately with an oil
binding agent and discard in accordance with
laws and regulations. Discard old fluids as speci­fied.

12 153 146

C 9.92

Observe applicable laws and regulations. Oils
are inflammable. Do not let them come in
contact with hot engine parts as fire can re­sult.

Hydraulic oil, brake fluid

During tractor operation, these fluids are pres­surized and pose a health hazard. Do not spill
these fluids. Remove any spilled fluids imme­diately with an oil binding agent and discard
them as specified. Discard the old fluid 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 a suitable
personal protector (for example, protective
gloves, glasses and skin protection and skin
care creams).

Operating Instructions

Operating instructions

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 old 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), carbon
hydride (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
a carcinogenic material.

153 146 13

Operating Instructions

Operating instructions

Particularly the particulates 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. Therefore keep the
exhaust pipe away from inflammable materi­als.

Battery

During charging the battery emits a mix of
oxygen and hydrogen (detonating gas). This
gas mix is explosive and must not be ignited.
The danger of explosion can be avoided with
suitable ventilation and the keeping naked
fires away. Observe the safety rules when
handling the battery.

Checking the trailer coupling (optional) if necessary

- Check the trailer coupling for proper condition and

operation. Carry out the check according to the
instructions in the section „Operating the trailer
coupling“.

Checking the tire inflation pressure

NOTE

Your tractor can be equipped with different
types of tyres. The specified inflation pres­sure for your tires is given in the table enti­tled „Tires“ in the technical data section.

- Check the inflation pressure an all four tires. All tires must

have the same pressure. Low pressure will increase the
rolling resistance. This will cause increased fuel con­sumption and tire wear, and the driving characteristics will
become poorer.

DANGER

If the inflation pressure is too high, the tires
can explode!

Taking into service

Operation

Before starting to drive

Operating Instructions

When driving on public roads, observe the traffic regula­tions.

Driving safety rules

• Drive the tractor only from the driver’s station with the
cab doors closed.

• Always adjust your speed to the driving conditions
and the load carried.

• Before driving, check that no-one is standing in the
immediate vicinity of the tractor.

• The driving behaviour of the tractor is strongly affect­ed by the weight and swing range of the attachments,
trailers and, if fitted, ballasting. Therefore drive slowly
with heavy equipment and take the longer braking
distance into consideration.

153 146 59

• When following a curve with a trailer or other attach­ments, do not forget to take the added length and drag
into consideration.

DANGER

Any parts of the attachments posing a traffic
hazard must be covered or identified with
warning signs before driving off.

• Switch off the differential lock when travelling in a
curve.

• When driving on slopes, always drive downhill if
possible; if you have to turn, only make a turn uphill.

• On steep slopes you can improve traction by activat­ing the differential lock.

• Drive across slopes only in accordance with the
instructions at the end of this section.

Operating Instructions

Operation

Driving

Driving with hydrostatic drive

- Start the engine.

- Preselect the direction of travel with the direction
switch (1).

- Pull up the direction switch (1) and move it forward or
backwards (forward or reverse).

NOTE

After the start of the engine, the direction
switch must be operated once if it was in the
forward or reverse position when starting. This
feature is to prevent accidental movement of
the vehicle when starting the engine.

Driving on slopes

DANGER

Driving on slopes is dangerous as the tractor
can tip over if the centre of gravity exceeds
the tip-over limit on an extreme slope.

The following factors will reduce the hazard:

- small or no load

- low ground speed

- low gradient

- low tire inflation pressure

NOTE

The driving comfort and the traction of the
tractor can be improved by reducing the in­flation pressure.

- large track widths

- level, non-bumpy terrain.

For turning on slopes we recommend proceeding as shown
in the drawing on the right.

attachments for use with this tractor. Only attachments with
the CE mark may be used. We recommend contacting our
customer service before the installation of special equip­ment.

Possible attachments

For example:
implements for orcharding
implements for soil cultivation
mowers
snow removal equipment
and other municipal equipment.

Safety instructions for handling attach­ments

The tractor must be parked safely before the installation of
attachments.
It must be secured against rolling, for example, with the park­ing brake or, if required, with chocks.

DANGER

Be careful to avoid injuries due to crushing
and cutting when coupling attachments.

DANGER

Never let anyone stand between the tractor
and an attachment or implement if the tractor
is not secured against rolling.
For driving on roads, the attachments must
be lifted and secured against lowering.
Observe the applicable safety regulations for
your attachment. Observe the operating in­structions and the safety rules for your at­tachment.

DANGER

During work breaks, the attachment must al­ways be lowered to the ground in order to
relieve the hydraulic cylinders. Accidents can
occur if lowering occurs in an uncontrolled
way, for example, due to damage or acciden­tal movement of the control levers.

DANGER

Any parts of the attachments posing a traffic
hazard must be covered or identified with
warning signs before driving.

Additional information for attachments

When installing attachments on the front and
rear lift arms, do not exceed the permissible to­tal weight, the maximum allowable axle loads
and tire carrying capacities of the tractor. The
front axle of the tractor must always be loaded
with at least 20 % of the tractor’s curb weight.
Before purchasing any equipment, make sure
these conditions are met by performing the fol­lowing calculations or by weighing the tractor­equipment combinations.

Determination of the total weight, axle loads and tire
load capacity including minimum ballasting

For the calculation you need the following data:
