contact with skin and it can irritate
mucous membranes, eyes, digestive or
respiratory organs. Some of them can
cause poisoning when swallowed.
42. The operators who come in contact
with oil products are obliged to heed
strictly safety and hygienic
instructions, make use of appropriate
protecting means, and work in wellventilated areas.
CRUDE OIL PRODUCTS
HANDLING
43. On termination of work or prior to
start eating, wash yourself with a
non-irritant agent and treat your
hands with a suitable skin ointment
or cream.
44. When connecting and disconnecting
the quick couplings of hydraulic
circuit, remove – with a piece of any
cloth – the residual oil, which
remains in the coupling socket or
possibly on the plug.
WASTE DISPOSAL
45. When disposing of the tractor or
some of its parts (including the
service liquids), as soon as their
service life is over, everybody is
obliged to proceed in accordance
with the provisions of the relevant
acts and regulations being in force in
a country, in which the tractor is
operated. The last tractor seller is
obliged – under the Waste Disposal
Act – to inform the consumer – when
selling the tractor – on the ways of
taking back some of the consumed
parts of the tractor. In question are

CAB AIR CIRCULATION CONTROL (D)
a - surrounding (ambient) air is sucked
through filters into the cab - air suction
from the cab is closed.
b - air is sucked from the cab interior and
again drawn into the cab (inner air recirculation for the fast temperature
adaptation in cab)
In this position the air inlet from
outside of the cab is fully closed
and in the cab no overpressure,
which prevents penetration of
non-filtered air into the cab, is
created! Use this position of the
control for urgently necessary
time only!
CORRECT FUNCTION OF HEATING
AND AIR-CONDITIONING
It is necessary to create overpressure in
the cab for a proper function of heating
or air-conditioning. Therefore we recommend shutting all windows, doors and
cab roof cover.
QUICK CAB INTERIOR HEATING
Proceed as follows:
1. Turn the heating valve control (A) to
the right-hand position (heating
valve fully open).
2. Set the air circulation control in the
cab (D) to the position of inner recirculation.
3. Choose the desired fan speed (positions 1, 2, 3) by the fan switch (B).
4. Set outlets to desired angle to avoid
direct blowing to persons in the cab.

COOLING THE CAB INTERIOR
QUICKLY
1. Move the heating valve control (A) to
the left-hand position.
2. Set the air circulation control in the
cab (D) to the position of inner recirculation.
3. Choose the desired fan speed (positions 1, 2, 3) by the fan switch (B).
4. Use the switch (C) to turn on the airconditioning.
5. Set outlets to desired angle to avoid
direct blowing to persons in the cab
(possible illness because of intensive
cooling of parts of persons bodies).
E124
HEATING OR AIR-CONDITIONING
OPERATION DURING TRACTOR
OPERATION
With the inner air recirculation switchedon, the inlet of fresh air is closed and it
comes to breathing-up of the cab space
by operators. This state can cause feelings of tiredness.
Note: When working, set the control (D)
according to your individual requirements
to temperature in a position between (a)
and (b) so that the fan could suck the air
from outside of the cab through filters.
E125
IMMEDIATELY AFTER THE CAB
COOLING
Immediately after cooling the cab and
reduction of the inner temperature to desired level we recommend:
− Switch over the air circulation control
(D) from position (b - air recirculation)
to position (a - outer air suction).
− Perform fluent regulation of air temperature with switched-on airconditioning by means of half-opening
of the heating valve (A). During this
setting, air flowing into the cab from
vents is not dried so intensively.
− You can perform fluent regulation of air
temperature with switched-on airconditioning by decreasing the fan

BEFORE ENGINE STARTING
Before starting the engine be sure that:
1. tractor is braked properly
2. main gearshift lever is in neu-
tral position.
If the clutch pedal is not depressed, the tractor cannot be
started - the start safety switch is
not actuated.
Note: Before starting proper we recommend to prime the fuel system by several
strokes of hand fuel delivery pump.
ENGINE STARTING
1. Insert the key into the ignition lock
("0" position).
2. Depress the clutch pedal.
3. Move the main gearshift lever into
neutral position.
4. Set throttle to increased fuel delivery
(approx. 1/2 of maximum delivery).
5. Turn the key from “0” position to "I"
position. The glow-plug indicator light
comes on.
6. Wait until the indicator light goes out
(the time depends on the coolant
temperature).
In case that the indicator light
flashes only instead of lighting,
the glowing system failed (see
Chapter Signalling of glowing
system failures). Have the indicated failure corrected at the
authorized service centre.
7. Immediately after the indicator light
has gone out (max. within 5 s), turn
the key from position "I" into position
"II" (start).
8. Release the key immediately after
starting the engine, it returns automatically into ”I” position. Do not op-
erate the starter for more than 15 s.
9. After starting the engine, gradually
reduce the fuel delivery.

TRACTOR OPERATION
E204 E205 E206
IF THE ENGINE DOES NOT START
Turn the key into position "0", wait 30
seconds and repeat the start.
Maximum 6 starting cycles are allowed
(15 seconds starting and 30 second
interruption make one cycle). Further
engine starting attempt is allowed after
cooling down of starter motor to the
ambient temperature.
Never help the stopping engine
by the starter motor. It may be
suffer damage this way.
SIGNALLING OF GLOWING SYSTEM
FAILURES
Flashing of the glowing indicator light
indicates failure in the glowing system.
- If the glo wing indicator light is flashing
once in a second with the stopped engine, glowing will take place in emergency regime as at low temperature
regardless to coolant temperature.
- If the glo wing indicator light is flashing
twice in a second with the stopped engine, the glowing is put of operation.
- If the glo wing indicator light is flashing
permanently with the engine running,
failure of the glowing regulator occurred and glowing was not finished. It
is necessary to correct the failure immediately, because there is danger of
battery discharging.
STARTER MOTOR HANDLING
It is forbidden to start the tractor by short circuit of starter
motor connectors!
Start the tractor from the
driver’s seat only!
When handling or repairing the
starter motor, remember to disconnect the negative battery
terminal and move all gearshift
levers into neutral position, including PTO shaft engagement!
Starter motor connectors are
covered with caps.

E207
E208
IMMEDIATELY AFTER START
After starting set the engine
speed to 800 - 1,000 rpm and let
the engine run at idle for about 2
minutes without load.
In the meantime check lubrication,
charging (indicator lights must go out)
and other functions assuring a correct
engine operation. Be sure to keep the
time of engine idle run without any load,
especially in winter season.
ENGINE PREHEATING
Continue to preheat the engine already while driving. W arming up the engine
by long idle run time or fast increase of speed is dangerous for the engine.
Do not exceed the engine speed of 2,000 rpm until the coolant te mperature
reaches 45 °C.

∗COOLANT HEATER
The coolant heater is installed on the
right-hand side of the engine block.
Output 1,000 W
Voltage 220 V
STARTING THE ENGINE USING THE COOLANT HEATER
The heater allows starting the engine at low ambient temperatur e by preheating the
coolant. The electrical system and its protection against ele ctrical shock hazard must
be done according to valid regulations.
1. Plug the heater first.
2. Plug the cable with connected heater to 220 V mains after.
With regard to reduction of engine wear when starting at low t emperatures, the producer recommends to use the heater. The preh eating time depends upon the ambient temperature (1 to 2 hours before supposed starting are sufficient).
Having finished the heating, unplug the mains first and the heater only after!
Electrical shock hazard!
It is necessary to ensure instruction of tractor operators and regular
revisions of the coolant heater including the inlet cabl e in accordance
with valid standards of the country, in which the tractor is operated,
minimum before each winter season.

At sudden air pressure drop in
the tractor air pressure system,
the front driving axle is automatically engaged.
DRIVING WITH THE FRONT DRIVING
AXLE ENGAGED
Use the front driving axle when rear
wheels are slipping to increase the
tractor traction force. On the road a nd
on hard ground the driving with the front driving
axle engaged is permissible within maximum
speed of 15 km/h (the driving with the front
driving axle engaged on the road and on hard
ground causes excessive wear of front tires).
Permanent engagement of front driving
axle is permitted if the agriculture machine or implement is attached to front of
the tractor. This condition is specified in
Operator’s Manual of each particular
machine. Maximum permitted speed of
the tractor combination is 15 km/h in that
case.

TRACTOR OPERATION
E224 E225 E226
SERVICE BRAKES
Foot brakes are of disc, wet, hydraulically actuated, double pedal type with
automatic pressure compensator.
Both brake pedals must be
latched together on the move.
Use unlatched pedals to brake
the right or left wheel separately
when working in terrain and field
at low travelling speed only.
Note: When driving downhill in sharp descent with a trailer or semi-trailer being
equipped with air or hydraulic brakes, it is
necessary to apply the service brake already from the beginning of the downhill
drive!
When braking with one brake
pedal, the trailer brakes are not
actuated!
AIR BRAKES OF T RAILERS AND SEMI-TRAILERS
Control of air brakes of trailers (semitrailers) is performed in such manner that
the brake effect of both vehicles is synchronized.
When driving with the hitched
trailer or semi-trailer, the service
brake pedals must be connected
together and secured with latch!
When braking with one brake
pedal, the trailer air brakes do
not operate.
Note: At pressure drop, the relief valve
puts secondary appliances (differential
lock, disengagement of front driving axle)
out of operation.
AIR PRESSURE DROP WARNING
LIGHT
The red indicator light located on the
dashboard indicates the air pressure
drop below the critical value of 450 kPa.

TRACTOR OPERATION
E230 E231
HYDRAULIC TRAILER BRAKES
The control of hydraulic trailer (semi-trailer) brake an d the tractor brake is performed
so that their braking effect is synchronized. The oil pressure is created by the oil,
which is drawn from the gear-type disengaging hydr aulic pump (1). The brake valve
(2) is installed behind the pump into the circuit.
The brake fluid pressure from master brake cylinders controls the trailer brake valve
in dependence on the force acting on the brake pedal. Pressure in the br ake cou pling
(3) must be 12 - 15 MPa at maximum depression of the brake pedal. The trailer brake
valve prefers the brake system function to the hydraulic system function. When
bleeding the tractor brakes, do not forget to bleed also the brake valve. In case that
during depression of service brake pedals shocks occur in the piping of the hydraulic
circuit, it is necessary to de-aerate the hose (4) leading fr om the brake valve (2) to

HYDROSTATIC STEERING MALFUNCTION WARNING LIGHT
When the oil pressure drops below 120
kPa behind the pump, it means a malfunction of hydrostatic steering pump,
which is indicated by lighting of the corresponding symbol on the dashboard.
Note: The warning light can flash during
the engine start or at low engine speed;
if it goes out after starting the engine or
after engine speed increase, there is no
malfunction. The system is OK.

HYDRAULIC SYSTEM
E401 E402 E403
HYDRAULIC SYSTEM
It consists of inner and outer circuits.
The source of the pressure oil is the
gear-wheel pump.
The oil is delivered from common filling
of the gearbox and axle final drive gear.
HYDRAULIC PUMP
The hydraulic pump cannot be
disengaged. When the engine runs, the
hydraulic pump is in function.
Hydraulic pump is alternatively supplied
in two sizes:
Pump type Pump capacity
1. UD 20 50 l/min
2. UD 16 40 l/min
The relief valve limits the pressure
induced in the hydraulic circuit to 18
MPa.
HYDRAULIC OIL FILTRATION
The hydraulic pump sucks the oil through
the suction filter located on the left-hand
side of the gearbox. You can replace the
oil filter element without draining the oil
from gearbox.
The oil will spill from the filter body
during the filter cartridge replacement. A
clean vessel of approximately 10 l
volume must be used. Prepare a new
cartridge in advance. Pour the spilled oil
back into gearbox (it holds in case that
the filter element must be replaced
outside of recommended time for the oil
or filter element replacement).

b - Height adjustment of three point
hitch with implement when position
control is selected and height
adjustment of ploughing depth with
draft or mixed control is selected
c - Setting of so called free (floating)
position when working with an
implement equipped with its own
supporting wheel
96
HYDRAULIC SYSTEM
E407 E408
SELECTION LEVER OF CONTROL MODE
The lever has three positions marked P, M or D
P -
This marks the position control, at which the implement attached to the
three-point hitch is automatically kept in constant height (position) with
regard to the tractor.
M -
This marks the mix control, which is a combination of position and draft
controls. This is suitable especially for ploughing at soils with variable soil
resistance.
D -
This marks draft control, at which the implement attached to the three-point
hitch is automatically readjusted depending upon the soil resistanc e change.
All modes of control enable also work with implement having a s upporting wheel in
the so-called free (floating) position.
The selection lever of control mode must be moved into P position during
transport of the implement!
RESPONSE RATE CONTROL LEVER
The lever controls the hydraulic valve in
the distributor, which distributes the oil
flow to inner and outer circuit.
The oil flow in inner circuit is minimum, if
the lever is moved in the direction (MIN)
from the driver’s seat.
By the oil flow restriction at draft or mix
control the hydraulic system response
rate is reduced, for example when
ploughing under variable soil conditions.
97
HYDRAULIC SYSTEM
E409 E410
HYDRAULIC OUTER CIRCUIT
The hydraulic outer circuit delivers the
pres-sure oil into hydraulic implements
connected to hydraulic outer outlets
equipped with quick couplings.
Quick coupling sockets have inner
diameter 12.5 mm and correspond to
ISO international recommendation.
OUTER CIRCUIT CONTROL LEVER
The lever has three positions marked on label:
a -
Pressure is in quick coupling "1", quick coupling "2" is c onnected with return
line. Lever is moved into its rear margin position. The lever must be held in
this position; otherwise it is automatically moved into position "b" (neutral).
b -
Neutral position (locked). Outlets to quick couplings "1" and "2" are closed and
oil flow in attached hydraulic implement is blocked. The lev er is automatically
held in this position by spring.
c -
Floating (free) position. Both quick couplings "1" and "2" are connected with
return line and oil can freely flow in both directions. The lever is locked in this
position by ball lock, which is situated in the slide valve.
d -
Pressure in quick coupling "2", quick coupling "1" is connected with return line.
Lever is moved into its forward margin position. The lev er must be held in this
position; otherwise it is automatically turned into position "c" (floating position).

HYDRAULIC SYSTEM
E411 E412
REAR OUTLETS OF HYDRAULIC
OUTER CIRCUIT
The basic type of hydraulic outer circuit
outlets is equipped with three quick
couplings located on the panel.
According to position of the
corresponding control lever, pressure oil
is distributed into quick couplings "1" and
"2". The third quick coupling "0" is
connected directly with the space of the
axle final drive gear and is intended for
the oil returning from outer hydraulic
implements (for example from rotary
hydraulic motors, etc.).
A - Arrangement of quick couplings
corresponds with a tractor that is
equipped with hydraulic system
without selective control valve
B - Arrangement of quick couplings
corresponds with a tractor that is
equipped with hydraulic system with
selective control valve
Attached implements using oil
filling of hydraulic outer circuit
must be filled with the same kind
of oil as recommended for the
tractor transmission!
CONNECTION AND DISCONNECTION OF
QUICK COUPLINGS
When connecting and disconnecting the quick couplings,
pay high attention to residual oil,
which remains in the socket
and/or on the quick coupling plug.
For environmental reasons, it is
necessary to remove this residual
oil with a piece of cloth after each
disconnection of quick couplings.

E413
OIL VOLUME SUPPLIED FROM
HYDRAULIC OUTER OUTLETS
For maximum possible delivered oil
volume see the following chart.
With high oil supply, the hydraulic
pump might suck the air inside
and the pump could be damaged.
In case that after disconnecting of the
implement the oil level drops in the
gearbox (caused by its permanent
pumping from tractor into hydraulic
circuit of the implement), it’s necessary
to add the missing volume of oil.
