*AIR FILTER WITH ACTIVE CARBON
Filters with active carbon are installed instead of the standard dust filter and they are
replaced in the same way as the normal filters. The filter must be inserted with the
white side towards the grill. You will find the installation instructions in the “Maintenance instructions” chapter.
The filter is only used during spraying of pesticides; then it must be replaced with a
paper filter again as flying dust would clog the carbon filter in a very short time.
During its use the recirculation control must be in the position of “air suctioned from
the outside”
The fan control must be in the “maximum” position.
• WARNING: The filter does not provide complete protection from toxic substances
• When handling the filter wear protective gloves
• Do not clean or blow the filter with compressed air.
DANGER: Replace the active carbon filter every 200 hours or 36 months (the
production date is printed on the filter). If you feel the smell of pesticides in the
cab, replace the filter immediately and have the cab sealing checked. Used filters must be disposed of in specialized collection centres.
27
When pesticides are sprayed and
a heating filter with active carbon
is used, the recirculation control
must be in the “air suctioned from
the outside” position and the fan
control in the “maximum” position
to create overpressure in the cab.

to the cab via filters - air suctioning
from the cab is closed.
b - Air is suctioned from the inside of the
cab and blown into the cab again (air
recirculation fast quick adjustment of
temperature in the cab).
In this position the air inlet from
the outside of the cabin is completely closed and in the cabin
there is no overpressure that prevents penetration of unfiltered air
to the cabin!
Do not use this position of the
control during working operation
of the tractor!
PROPER FUNCTION OF THE HEATING
AND AIR-CONDITIONING SYSTEM
To ensure proper functioning of the heating or air-conditioning system it is necessary to create overpressure in the cab.
Therefore, we recommend you to close
all the windows, doors and tilting lid of
the cabin.
FAST HEATING OF THE CAB SPACE
Proceed as follows:
1 - Turn the heating valve control (A) to
the right position (heating valve fully
open).
2 - Set the control of air circulation in the
cab (D) to the internal circulation position.
3 - Use the fan control (B) to select the
corresponding fan speed (position 1,
2, 3)
4 - Set the outlets to the required angle to
avoid direct blowing of air to the persons in the cab.
5 - After heating of the cab space set the
control of air circulation in the cab (D)
to the position of suctioning external
air - see fig. F_02_17b, position (a).

QUICK COOLING OF THE CAB
SPACE
Proceed as follows:
6 - Turn the heating valve control (A) to
the left position.
7 - Set the control of air circulation in the
cab (D) to the position of suctioning
external air.
8 - Use the fan control (B) to select the
corresponding fan speed (position 1,
2, 3)
9 - Use the switch (C) to switch on the air-
conditioning system.
10 - Set the outlets to the required angle
to avoid blowing of air directly to the
persons in the cabin (possible occurrence of an illness due to intensive
cooling of body parts).
HEATING OR AIR-CONDITIONING
OPERATION DURING WORK OF THE
TRACTOR
When internal air circulation is on, the
fresh air inlet is closed and the air in the
cab space may be breathed up by the
operators. This situation may cause the
feeling of tiredness and further due to
overpressure loss in the cab dust may
penetrate to the cab.
Note: During work set the switch (D) in
accordance with individual requirements
to a temperature in a position between
(a) and (b) so that the fan can suction air
from the outside via filters.
IMMEDIATELY AFTER COOLING
DOWN THE CAB
Immediately after cooling of the cab and
reduction of the internal temperature to
the required value we recommend you
to:
− Perform smooth regulation of air temperature with the air-conditioning on by
partially opening the heating valve (A).
At this setting the air entering the cabin
from the outlets is not dried so intensively.
− You can also smoothly regulate the air
temperature with the air-conditioning
on by reducing the fan output by
switching the control (B) to position 1
or 2.

FRONT WINDSHIELD (B) DEFROSTING
To ensure quick defrosting of the front windshield direct the central heating outlets (3)
under the angle of approx. 45° towards the windshield. Direct the side outlets (4) under the angle of approx. 45° to the cab corners.
After defrosting of the front windshield direct the side outlets to the side glasses of the
doors as necessary and gradually defrost them. After defrosting direct the outlets in
such a way that the air should not be blown directly to the driver, but down to the
driver’s legs.

make sure:
1. that the tractor is properly
braked
2. that the main gear shifting lever
and the reversing lever is in
the neutral position
3. that the PTO switches on the
right cab pillar are off.
If the clutch pedal is not pressed,
the engine cannot be started - the

IF THE ENGINE WILL NOT START
Return the key to position “0”. Wait for 30
seconds and repeat the start.
Never support the stopping engine with the starter motor. There
is a danger of damaging the
starter motor.
PROHIBITED STARTING METHODS
It is forbidden to start the engine
by short-circuiting the starter
motor terminals. Only start the
tractor from the driver’s seat!
During any handling or repair of
the started motor the minus pole of
the battery must be disconnected
and all the shifting levers, incl.
PTO must be moved to the neutral
position. The starter motor contacts are covered with a cap.

F_02_29 F_02_30 F_02_176
STARTING THE TRACTOR ENGINE
The tractors are equipped with glowing
plugs in the cylinder heads as standard.
1. Insert the key into the switching box
(position “0”).
2. Depress the clutch pedal.
3. Move the main shifting lever and the
reversing lever to the neutral position.
4. Adjust the throttle for increased fuel delivery (approx. 3/4 of the maximum
quantity).
5. Turn the key to position “I”. The yellow
indicator signalling proper function of
glowing will light up on the dashboard.
DRIVING OPERATION
6. Wait until the glowing indicator goes off
(the time depends on the temperature
of the cooling liquid).
If the glowing indicator only
flashes instead of lighting, an error has occurred in the glowing
system (chapter Indication of errors of the glowing system). Have
the reported error repaired in a
specialized repair shop.
7. Turn the key to position “II” (start).
8. Release the key immediately after starting the engine. Do not start the engine
for more than 15 s.
9. After starting the engine gradually reduce the fuel delivery. Thus, you will
prevent unnecessary operation of the
engine at high engine speed.
50
INDICATION OF ERRORS OF THE
GLOWING SYSTEM
An error of the glowing system is indicated by flashing of the glowing indicator.
- If at engine standstill the glowing indicator flashes once a second, the glowing
will occur in the emergency mode as at
low temperatures regardless of the
coolant temperature.
- If at engine standstill the glowing indicator flashes twice a second, the glowing
is off (out of operation).
- If the glowing indicator flashes permanently during engine operation, the
glowing controller is faulty and the
glowing has not been finished. This
failure must be removed immediately
as the battery might get discharged.
DRIVING OPERATION
XF_02_185a F91
∗COOLANT HEATER
The coolant heater is installed on the engine block.
The output of the heater is 1000 W at the
220 VAC supply voltage.
STARTING THE ENGINE WITH THE USE OF THE COOLANT HEATER
Heating the coolant facilitates engine starting at low ambient temperatures. The electric installation of the power supply and its protection against electric shock must
comply with valid regulations.
1. First, insert the connector to the heater.
2. Then, connect the heater to electric mains with the voltage of 220 V.
With regard to reduced wear of the engine during starting at low temperatures, the
use of the heater is recommended by the manufacturer. The heating time depends on
the ambient temperature (1 - 2 hours before the planned start should be sufficient).
After the end of heating first disconnect the device from the electric mains and
only then remove the connector from the heater!
Electric shock hazard!
It is necessary to ensure instructing of the tractor operator and regular
inspections of the coolant heater, incl. the power supply cable in the
sense of valid standards of the state where the tractor is operated, at
least before every winter.
51
DRIVING OPERATION
F_02_33a F_02_35
IMMEDIATELY AFTER STARTING
After starting set the engine
speed to 800 - 1000 rpm and let
the engine run without loading for
approx. 2 minutes.
During this time check the lubrication,
charging, hydrostatic steering (the indicators must go off) and other functions ensuring proper operation of the engine.
The period of running the engine without
loading must be observed, especially in
winter.
ENGINE PREHEATING
Continue preheating the engine while driving. Preheating the engine by
means of a long idle run or abrupt increasing of the engine speed is harmful
for the engine.
Until the coolant temperature reaches 45°C, do not exceed the engine speed
of 2000 rpm.
52
F_02_34 F_02_43 F96
GEAR SHIFTING
The tractors are equipped with a fourspeed synchronized gearbox, threestage torque multipliers and two-speed
reduction.
The four-speed gearbox is controlled
with the main shifting lever with control
buttons of the torque multiplier (1). The
forward and reverse motion of the tractor
is selected with the reversing lever (2).
The gearbox does not make it
possible to use the fourth speed

F_02_37 F_02_38 F106
DRIVING UPHILL
When driving uphill, shift from the
higher to the lower speed in time
to avoid the engine speed dropping below 800 rpm and avoid
such driving that would lead to
stopping of the engine due to
overloading.
DRIVING OPERATION
DRIVING DOWNHILL
Driving downhill without an engaged gear is prohibited. When
driving down a longer slope, shift
the lower gear, the steeper the
slope is. If possible, shift the
lower gear before the slope already.
Note: The gear that allows you to get
uphill reliably is also suitable for getting
down the hill safely.
FOOT BRAKES
The foot brakes are of the disc, wet, hydraulically controlled, double-pedal type
with an automatic pressure compensator.
During driving on a road both the
pedals must be connected with a
latch. Only use unlatched pedals
for braking the right or left wheel
separately during terrain work
and in the field.
Note: When driving down a steep slope
with a trailer or semi-trailer equipped with
air or hydraulic brakes you must use the
foot brake from the beginning of the
slope already.
During braking with one brake
pedal the trailer brakes are not
in operation!

F108 F_02_39 F_02_55
AIR BRAKES OF TRAILERS AND
SEMI-TRAILERS
The control of the air brakes of trailers
(semi-trailers) and the control of the tractor brakes is designed in such a way that
the braking effect of both the vehicles is
synchronized.
The working pressure is set by the pressure controller to 740 ± 20 kPa. If the
pressure drops below 550 - 40 kPa, the
relief valve puts the secondary devices
(differential lock, engagement of the front
driving axle, etc.) out of operation.
WARNING INDICATION OF AN AIR
PRESSURE DROP
A pressure drop below 450 kPa is signalled by lighting up of the red indicator
located on the dashboard.
In case of a pressure drop below
450 kPa in the air pressure system a tractor with a braked trailer
or semi-trailer must not continue

DRIVING OPERATION
E230a
HYDRAULIC BRAKES OF TRAILERS
Connect the hydraulic brakes of a trailer or semi-trailer to the quick-coupler marked
with an arrow.
The control of the hydraulic brakes of trailers (semi-trailers) and the control of the
tractor brakes is designed in such a way that the braking effect of both the vehicles is
synchronized. The working pressure is applied by oil delivered by a permanent gear
pump of the hydraulic system.
The brake valve of the trailer is controlled by the pressure of the brake liquid from the
main brake cylinders depending on the force applied onto the brake pedal. At the
maximum depression of the brake pedal the pressure at the coupling must amount to
12 - 15 MPa. The brake valve makes sure that the brake function overrides the hydraulic function.
If during depression of the foot brake pedals shocks occur in the hydraulic circuit, it is
necessary to bleed the hose leading from the brake valve to the quick-coupling.
During driving with a hitched trailer or semi-trailer the pedals of the foot brake
must be connected and secured with a latch.
During braking with one brake pedal the hydraulic brakes of the trailer
are not in operation.
CONNECTING AND DISCONNECTING
QUICK-COUPLERS OF HYDRAULIC
BRAKES OF THE TRAILER
When connecting and disconnecting the quick-couplers pay
increased attention with regard to
the residual oil that remains in the
socket or on the plug of the
quick-coupler.
For environmental reasons after
every disconnection of quickcouplers this residual oil must be
removed with any textile material.

FRONT DRIVING AXLE CONTROL
The front driving axle is “ON” in basic
position (the indicator lights up). It can be
disengaged with the corresponding
switch on the dashboard.
a - Front driving axle “ON”
b - Front driving axle “OFF”
When the tractor is stopped (the tractor
is braked, engine stopped, key of the
switching box off), the front driving axle is
“ON”.
DRIVING OPERATION
DRIVING WITH THE FRONT DRIVING AXLE ENGAGED
Use the front driving axle in case the rear wheels slip to increase the traction
of the tractor.
On a road and hard surface driving with the front driving axle engaged is acceptable up to the maximum speed of 15 km/h (driving with the front axle engaged causes increased wear of the front tyres).
Permanent engagement of the front driving axle is permissible if an agricultural machine or implement is attached to the front of the tractor. This condition is mentioned
in the operator’s manual of the corresponding machine.
The maximum allowable speed of these sets is 15 km/h.
61
F_02_40 F_02_60 XF_02_186
ENSURING FREE SPACE FOR THE
CARDAN SHAFT OF THE FRONT
DRIVING AXLE
When installing auxiliary units or
connecting implements make
sure that around the Cardan shaft
of the front driving axle there is at
least 10mm free space all along
its length at any oscillation of the
axle.
If this principle is not observed,
there is a danger of damaging
the tractor and machine.
DRIVING OPERATION
STOPPING THE TRACTOR - PARKING
BRAKE
Under normal conditions stop the tractor
slowly. Shortly before stopping:
1. Depress the clutch pedal.
2. Shift the main gear shifting lever to the
neutral position.
3. After every stopping secure the tractor
against accidental movement with the
parking brake. Activation of the parking brake is signalled by illumination of
the corresponding indicator on the
dashboard.
STOPPING THE ENGINE
After work of the tractor when the engine
was fully loaded, the engine must be left
to cool down.
1. Before stopping the engine reduce the
engine speed to 800 - 1000 rpm and
let the engine run without loading for
approx. 5 minutes.
2. Move the manual throttle lever to the
STOP position.
3. Pull up the control of the engine stopping device and hold it in the extended position until the engine operation stops.
4. After stopping the engine you can turn
the key from position “I” to position
“0”.
62
F_02_67 F_02_68
LEAVING THE TRACTOR
You can turn the key from the “I” to the
“0” position only with the engine at
standstill - the charging indicator must be
lit.
If the tractor is standing on a slope, it
must be secured against spontaneous
movement: braked with the parking
brake, engine stopped, the reversing
lever shifted depending on the tractor inclination on the slope either in the forward or reverse position, the main shifting lever engaged in a low gear position
and the wheels secured with wedges.
Before leaving a tractor with the
safety cab remove the key from
the switching box and lock the
cab.
DRIVING OPERATION
Note: When the engine is stopped, the
front driving axle is automatically engaged.
WARNING INDICATION OF A
HYDROSTATIC STEERING ERROR
An error of the hydrostatic steering pump
is signalled in case of a pressure drop
below 120 kPa downstream of the pump
on the dashboard by the corresponding
symbol.
Note: During starting of the engine or at
low engine speed the indicator may flash
slightly; if after starting or increase of the
engine speed the indicator goes off, it is
not an error.

GENERAL PRINCIPLES FOR RUNNING IN THE NEW TRACTOR IN THE
COURSE OF THE FIRST 100 HOURS OF OPERATION
During the first 100 operation hours:
- Load the engine normally
- Avoid operation under partial loading of the engine
- Avoid excessive idle run
- Frequently check the oil level in the engine (increased oil consumption is normal in
this period).
- Check screw connections mainly of the supporting parts of the tractor.
- Immediately remove all established shortcomings; thus, you will prevent
subsequent damage and possible impairment of operation safety.
- Proceed in the same way after a general overhaul of the tractor as well.

HYDRAULIC SYSTEM
CONNECTING MACHINES AND IMPLEMENTS TO THE OUTER HYDRAULIC
CIRCUIT
Connecting machines and implements consisting of more parts
During work with agricultural machines that consist of more parts (combinators, skids,
harrows) and that have side frames hat are hinged to the central frame and during
transport are folded to the vertical position by separate hydraulic cylinders controlled
by the outer hydraulic circuit of the tractor, the folding of the side frames must always
be controlled by the upward (backward) movement of the auxiliary distributor lever.
The “lifting” branches of the cylinders must be connected to quick-couplers “2”, “4” or
“6”.
Connecting a rotational hydraulic motor
If a rotational hydraulic motor is connected to an outer outlet of the hydraulic system,
its return branch must always be connected to quick-coupler “0”. In case of connection of the filling (pressure) branch to quick-coupler 1 or 2 the hydraulic motor is protected by the kick-out function against overloading. This function interrupts the operation of the hydraulic motor at the pressure value in the filling branch of 17.5 - 1.6
MPa.
Connecting a reversing hydraulic motor
A reversing rotary hydraulic motor must be connected to quick-couplers “1” and “2”
for functional reasons. However, relief valves must be inserted in both the branches
in this case as they can reliably limit the pressure peaks during the stopping of the
machine. The oil return lines from these valves are connected to quick-coupler "0".

(9) are off. After a short time permanent
illumination of the diagnostic LED (7) indicates the state of EHR-B blocking.
If the diagnostic LED (7) is permanently
illuminated, the control circuits are disconnected.
ELECTRO-HYDRAULIC SYSTEM
The engine can only be started
if the engine (1) is in position
(b).
The EHR-B electro-hydraulic system is
only active when the engine is started.
Activation of the EHR-B system is only
possible when the lubrication indicator
has gone off.
The blocking can only be cancelled (system activated) with the engine running by
moving the lifting lever (1) to position (a)
- short-time switching is sufficient.
By moving the lever (1) to position (c)
you will bring the three-point hitch to the
position corresponding to the element
setting, i.e. the current position of controls (4), (5), (6).
91
After the activation of the system
EHR-B first for safety reasons
limits the lifting speed of the hydraulic arms.
When the hydraulic arms first
reach the selected position, this
safety limitation is cancelled and
then the lifting speed of the hydraulic arms is normal.

QUICK SINKING
Lever (1) in position (d) - free position.
You must hold the lever in this position;
after releasing the lever will return to position (c) - the system works in accordance with the setting of controls (3), (4),
(5) and (6).
ELECTRO-HYDRAULIC SYSTEM
TRANSPORT OF IMPLEMENTS
Shift the lifting lever (1) to position "a"
and block it with the moving latch (2).
Blocking the lifting lever (1) by the moving latch (2) in position (a):
A - Lever movement blocked
B - Lever movement not blocked
When the tractor with an attached
implement is stopped, the implement must be lowered onto the
ground (it must not be left in the
lifted position).
92
STOP POSITION
By moving the lever (1) to position (b) STOP position - you will immediately
stop the movement of the three-point
hitch.

VIBRATION COMPENSATOR (DAMPER)
It is used during transport of a heavy implement attached to the rear three-point hitch.
After activation of the vibration compensator (10) the arms of the rear three-point
hitch sink by approx. 4%, which allows oscillation of the arms in the range of approx.
8% of the lift. The upward oscillation is always limited by the position of the upper position limiter (5).
Advantages of active dampening of vibrations during transport of a heavy implement
attached to the rear three-point hitch.
1. Increased operation safety (the steering axle is not unloaded so much
2. Stabilization of the transported implement
3. Reduced dynamic stress of the hydraulic system and the rear three-point hitch
During the adjustment of the hitch for a single-axle semi-trailer the vibration
compensator must be off.
LIMITATION OF THE UPPER
POSITION OF THE THREE-POINT
HITCH
It is activated with the control (5). The
limitation can be implemented in the upper half of the three-point hitch lift.

FREE POSITION
For permanent work with free hydraulic
system, e.g. during work with a plough
with a support wheel the position of the
control (4) under the indication (A) and
the position of the control (6) at the positional control symbol is used.
94
WORK IN THE FIELD
Perform the steps described in the
“Blocking cancellation” section and set
the required position of the elements with
regard to the character of the planned
work. The control (4) is used to achieve
the depth of the implement. To set the
control type and their combination use
the control (6).

The control activity (lifting and lowering)
can be monitored with the use of the indication diodes (8) and (9). At the dead
point shift the lever (1) to position (a) and
after reversing of the direction move it to
position (c) again. The control system will
return to the previous working position
(ploughing memory). The control (3) is
used to set the required lowering speed.

USING THE REAR CONTROL
The rear control is used to connect and
disconnect implements. The lifting
switching lever (1) on the EHR-B electrohydraulic control panel must be in position (b) or (c). The designation symbols
of buttons on both the tractor fenders
correspond to the movement direction of
the three-point hitch after their pressing.
The movement only lasts as long as the
button is held.
Every use of the rear control causes
blocking of the control system and the
“Blocking cancellation” must be repeated
- see page 130.
EXTERNAL CONTROL BUTTONS OF
THE ELECTRO-HYDRAULIC SYSTEM
1. Lifting
2. Lowering
The movement only lasts as long as the
buttons are held.
The external control buttons of the
electro-hydraulic system are functional without prior activation of
the system.
96
USING THE BUTTONS
When handling the three-point
hitch with the external control buttons the operator must stand out
of reach of the connected implement to avoid being caught or injured by the implement.

SAFETY PRINCIPLES OF WORKING
WITH THE THREE-POINT HITCH
Persons that are not authorized to
work with the attached implement
must not stand between the tractor
and the hitched machine (implement) - (A). Do not park the tractor
with an attached implement in the
lifted position (B). During a drive
without an implement the lower
draw-bars (5) must be connected
with springs and the upper drawbar (1) must be inserted into the
spring suspension! During transport
of implements the limiting drawbars (4) of the lower draw-bars
must be adjusted in such a way to
avoid unwanted lateral movement
of the implement!
