Principles for operating tractors equipped with front end loader
Carefully study operation manual supplied by the manufacturer of front end loader.
In cas
e of discord of Principles for operating tractors equipped with front end loader and operation
manual for front end loader, which was supplied by the manufacturer of front end loader, the wording
listed in operation manual supplied by the manufacturer of front end loader shall apply.
The use of front end loader for transporting material at places accessible to the public is forbidden.
The use of front end loader for transporting material in places inaccessible to the public is possible
only in a limited way. In such case, instructions in user's manual supplied by the loader manufacturer
must be observed.
Observe local valid regulations at all times.
A strict ban on transportation and lifting of people by means of loader is in effect.
No matter whether the front end loader is loaded or empty, no-one may stand in front of the loader if it
is in lifted position. When driving with a lifted loader, there is a risk of load transported by front end
loader falling (there is a risk of disrupting the balance of the tractor).
Never leave the tractor standing with the loader in lifted position.
If it is necessary to open the bonnet of the engine at intervention, disconnect the front end loader first
or secure hydraulic rollers of front end loader by metallic props designed for this purpose.
Hydraulic circuit of the front end loader is designed in such a way to endure the maximum operation
pressure of 20 MPa (200 bar). Do not do any changes on couplers of hydraulic circuit hoses.
Any front end loader ZETOR mounting without observing the recommendation of ZETOR TRACTORS
valid to the day of pur-chase revokes the validity of guarantee for the whole of supply.
The loader may be used, maintained and repaired only by people who perfectly know the machine
and who are informed about potential risks.
When driving on roads do not transport any material on the front end loader.
It is necessary to observe special instructions related to accidents prevention and general rules
related to technical safety, la-bour medicine, labour hygiene and regulation defining operation on
roads.
The manufacturer does not bear any responsibility for any potential damage incurred as a result of
changes conducted on the loader without their consent.
Do not ever adjust the front end loader by yourselves and do not use the adjusted front end loader
without prior ZETOR´s ap-proval. The loader may become dangerous as a result of not observing
these instructions. ZETOR TRACTORS shall not be held responsible in case of any damage or injury.
Use front end loader without additional weights on the tractor (danger of mutual contact). The load of
front and rear drive axle must not exceed the maximum permitted load listed in the manual. The use
of front end loader requires mounting of counter weight in the rear part of the tractor.
Each working tool was reconstructed for the purpose of specific usage and has its own tolerance of
resistance and tightness.
It is forbidden to use front end loader for cultivating soil and stubbing. Such work needs to be done
with a special tool, front end loader is not designed for doing this.
Using controls which would set the loader into motion without driver holding the gear shifting lever is
strictly forbidden and re-sults in installation not meeting the prescribed standard.
To penetrate the loaded material, better use the kinetic energy of the tractor rather than pressing force
which causes higher strain of both the loader and the tractor.
Do not overload hydraulic parts if the load is too heavy or pistons are in end positions.
Control the loader exclusively from driver's seat, if you are sitting on driver's seat.
Do not leave the seat if you have not blocked any movement of controls.
No people can be present in the working zone of the loader.
When working with a lifted loader, mind electric and external cables etc.
Loader/tractor set needs to be parked on a horizontal and solid base, the arms of the lifting device
must be set in the lower position
You will find more information in user's manual to front end loader.
Important notification: Work always safely and with consideration.

Zetor tractors used for work in the woods
Standard tractors Zetor do not provide sufficient protection for operation in forest terrain as, for example,
protec
tion against a fal-ling tree or branch on a cab or penetration of objects to a cab.
If Zetor tractor is utilized for forest work, a tractor operated within the European Union must be protected
against these risks.
It is necessary to observe applicable local valid regulations in countries which are not part of the European
Union.
To ensure this protection, it is advisable to conduct assembly of a specific protective structure, like for
example FOPS / OPS (Fal-ling Object Protective Structure / Operator Protective Structure), tested according
to standards for forest machines.
Only forest superstructures approved by ZETOR TRACTORS can be mounted to ZETOR
tractors.
In case of additional assembly of further tractor equipment for working in the woods, full responsibility is
borne by the supplier and manufacturer of the protective structure that all the safety regulations (e.g: OPS /
FOPS), all the conditions of homologation (e.g. the area of driver's view, lighting, parameters, permissible
weight etc.) are met, same as for the provision of due assembly of pro
-tective equipment. The
suppli
er/manufacturer of protective construction is also obliged to conduct all the necessary validation
(approval) steps required by the legislature of the country in which the tractor is operated.

same way as with standard filters. Filter must be inserted with the white side to the grid. Assembly
instructions are found in the chapter 'Maintenance instructions'.
Filter is used only when spraying pesticides, then it must be replaced back by a paper filter because the
flying dust would clog the carbon filter very fast.
The recirculation control must be in the position 'air is sucked from the outside'.
Ventilator control must be in the position 'maximum ventilator run'.
WARNING: filter does not provide full protection against toxic substances
- Wear p
rotective gloves when manipulating with the filter.
- Do not clean the filter and do not blow through with compressed air.
DANGER: Replace the active carbon filter every 200 hours or 36 months (date of production is
given on the filter). If you happen to smell pesticides in the cabin, replace the filter immediately and
have the sealing of the cabin checked. Used filters must be damaged in specialized collection
centres.
When spraying pesticides and using heating filters with active carbon, the recirculation
control must be in the position of 'air sucked from the outside' and the ventilator control 'maximum
ventilator run' for creating surplus pressure in the cabin.

condition with tractor´s work
Immediately after cooling the cabin
With e
ngaged inner recirculation of air is the inflow of
fresh air closed and there is foul air in the space of the
cabin by operator. This state can cause the feeling of
fatigue and there can also be penetration of dust to the
cabin because of the loss of surplus pressure.
Note: Set the control (D) according to individual
requirements on temperature to the position between (a)
and (b) so that the ventilator sucks the air from the outside
of the cabin through filters, when working.
When spraying pesticides and using the
heating filter with active carbon, the recirculation
controller should be in position 'air is drawn into from
the outside' and the fan controller should be in the
position 'fan maximum work' to create overpressure
in the cabin.
F_02_19
Immediately after cooling the cabin and lowering the inner
temper
ature on the required values, we recommend the
following:
- Switch over the control of air circulation (D) from position
(b - air re-circulation) to position (a - outer air suction)
- Do the continuous regulation of the air temperature with
air condition on by opening the heating valve (A). The air
entering the cabin from expiration is not so intensively
dried with this setting.
- Continuous temperature control with air-condition on can
be also done by lowering the output of ventilator by

Diesel particle filter
The activity of diesel particle filter is signalized by a pair of controls (green and red) on the dashboard. Diesel
partic
le filter system failures with engine running are signalized by a lit red control on the dashboard and then
with an acoustic signal.
A short-term turning on of the red control without a subsequent acoustic signal does not
signal
ize a failure.
The conditions suitable for diesel particle filter regeneration are signalized by a lit green control on the
dashboard with engine running. Clogging of diesel particle filter automatically regenerates the exhaust gases
temperature with higher engine load.
When operating tractors with engines equipped with diesel particle filter, avoid long-term
operation or low engine load.
Diesel particle filter - system failures signalization
The exhaust system of a tractor is equipped with
a diesel particle filter which serves for cleaning exhaust
fumes. Solid particles (carbon particles) are collected and
burned in diesel particle filter which originate by burning
diesel.
FH12N056
Failures in diesel particle system failure are
signal
ized by a red control lighting up on the dashboard
with engine running and subsequently by an acoustic
signal.
If the
failure is not removed, it is signalized with any
following starting of the engine
The code of failure us displayed on a display (1) of the
displaying unit which is accessible after removing the right
cover of the steering console.
The failures are displayed on display (1) in a form of E:

If failure is not signalized, operation data of diesel particle
filter system are displayed on the display.
The acoustic signal can be turned off by the button (2). If
the failure has not been removed, the acoustic signal is

36 Regenerate diesel
partic
le filter.
During the operation of a tractor, diesel particle
filter is clogged by solid particles originating in engine run
when burning fuel. Clogged diesel particle filter
automatically regenerates the temperature of exhaust
fumes
with higher load of the engine.
When operating the tractor with low load of the engine ,
e.g. with long-term operation on idle run, there is a partial
clogging of diesel particle filter. This condition is signalized
with the engine run by a lit red control of diesel particle
filter, and followingly also by acoustic signal and on the
displa
y of displaying unit of diesel particle filter by failure
code
E:36
If this situation occurs, increase the load of engine and
continue working until red control of diesel particle filter
switches off and acoustic signal does not stop.
By increasing the engine load, the temperature of exhaust
fumes increases and the solid particles which clog diesel
particle filter burn.
The conditions suitable for diesel particle filter
regeneration are signalized by a lit green control on the
dashboard.
Depending on the temperature of exhaust fumes and the
degree of diesel particle filter clogging, regeneration can
take up to thirty minutes.
When regeneration is achieved, notification
information signalization goes out (error 36). If this
signalization does not go out, repeat this procedure. If
it still does not go out, you need to address an
authorized service.

Control of hydraulic brakes of trailers (articulated trailers)
and control of tractor brakes is done so that the braking
effect of both vehicles is synchronized. Working pressure
is derived by oil supplied by non-switched on/switched off
gear pump of hydraulics. Brake valve of the trailer is done
by the pressure of brake fluid from main braking rollers
depending on the force effecting on the brake pedal. The
pressure on clutch head must be 12 - 15 MPa with
maximum depression of brake pedal. Brake valve of trailer
prefers the function of brakes to the function of hydraulics.
If there are shocks when foot brake pedals are depressed
in the pipeline of hydraulic circuit, it is necessary to bleed
the hose from the brake valve to the quick coupling.
When driving with connected trailer or
articulated trailer, the pedals of foot brake must be
connected and secured by a valve! When braking with

A double acting cylinder must always be connected to quick couplers of one section.
Connecting machinery and tools assembled from more parts
When working with agriculture machinery which is assembled from more parts (combinators, scrubbers, or
harrows) where the edge frame is hinged to the central frame because it is diagonally folded during transport
by independent hydraulic cylinders which are controlled by outer hydraulic circuit of the tractor, it is
recommended to connect the lifting arms of the cylinders to quick couplers (3) and (5) which are equipped
with a one-way valve.
Connecting rotary hydraulic engine
If a hydraulic engine is connected to outer hydraulic drive, it is always necessary to connect its returnable
arm to quick coupler (0). Filling (pressure) arm can be connected to quick couplers (1) or (2), where the
hydraulic engine is protected by the 'kick-out' function from overload. This function stops the hydraulic engin e
if pressure in the filling arm exceeds 17 MPa.
Connecting reverse rotary hydraulic engine
Due to its function, reverse rotary hydraulic engine must be connected to quick couplers of one section. It is
recommended to use quick couplers (1) and (2), where the hydraulic engine is protected by the 'kick-out'
function from overload. This function stops the hydraulic engine if pressure in the filling arm exceeds 17
MPa. If the hydraulic engine is connected to quick couplers of different sections, both arms must be
equipped with safety valves which can be relied on to restrict high pressure peaks during run-out. Connect
the safety valves drain to quick coupler (0).
Connecting external hydraulic distributor
It is recommend to connect external hydraulic distri bu tor to quick couplers (4) or (6). Control levers (b) and
(c) are mechanically locked in these positions without hydraulic lock.
Auxiliary machines using oil filling of external hydraulic circuit must be filled with the same
kind of oil, which is recommended for gear system of the tractor! Quick-couplers sockets of an
auxiliary machine need to be properly cleaned before connecting.
Front outlets of the external hydraulic circuit
On request, the tractor can be equipped with external
hydraulic circuit outlets located in the front.
The quick couplings (1) and (2) are the pressure
couplings, the quick coupling (0) is directly connected to
the space of the axle final drive housing and is designed
so that the return oil can flow back from the external
hydraulic appliances.
The quick couplings sockets with the 12.5 mm inside

Hydraulic system sensitivity control
Position regulation of the lifting of the rear three-point hitch
P+11N008
Position regulation of the lifting of the rear three-point hitch means that the tool connecte d to the rear threepoint hitch is automatically kept in the same height (position) with regard to the tractor.
Move lever (1) to the front position (d). Adjust the height of the rear three-point hitch with tools within the (b)
range by lever (2). Adjusting the height is smooth within the range 1 - 9. In position 1, the arms of the rear
three-point hitch are in the lower position, in position 9, in the highest position. Position (c) is a transport
position when the tools connected to the rear three-point hitch is raised at maximum.
To transport tools which are connected to the rear three-point hitch always use position
regulation.
To raise tools into transport position, turn the three-point hitch lowering speed control knob (3) in
the direction shown by the arrow up to the stop point, which results in int errupting the oil flow in
hydraulics. Should tools connected to the rear three-point hitch not be lowered, check the position of
the speed lowering control knob (3) - turn it in the opposite direction than shown by the arrow.
If tools connected to the rear three-point hitch are long and heavy, the arms of the rear three-point
hitch may get locked in the transport position during transport. If the lowering speed control knob (3)
is loosened and the tools still cannot be lowered, move lever
(2)
to the floating position (c) for a short
time and immediately get back to the lowering range (d). The arms of the rear three-point hitch start
to go down as set by lever (2).
Hydraulic system sensitivity control (4) adjusts the
sensitivity of the hydraulics in power or mixed regulation.
Turning the knob in (a) direction increases sensitivity,
turning it in (b) direction decreases sensitivity.

Power regulation of the lifting of the rear three-point hitch
P+11N010
Power regulation of the lifting of the rear three-point hitch means that the tool connected to the rear threepoint hitch is automatically being adjusted depending on changing soil resistance.
Set the adjustable stop (5) to a position on the edge between floating position and the beginning of the range
of lifting of the rear three-point hitch.
Move lever (2) to (f) position - to the adjustable stop (5).
Move lever (1) to (g) position, accelerate the tractor and move lever (1) in the direction shown by the arrow to
set the depth of tilling (in (g) position, depth is the lowest).
Once the depth of tilling is set, lever (1) must be kept in constant position. At the end of each row, raise the
tool connected to the rear three-point hitch only by moving lever (2) to (e) position. To lower the tool to its
operating position again, move lever (2) to (f) position.

To reduce oscillation, set lower hydraulic system sensitivity by turning the contro l knob (4) in (b)
direction.
Mixed regulation of lifting the rear three-point hitch
P+11N010
Mixed regulation of lifting the rear three-point hitch means that the tool connected to the rear three-point hitch
is automatically being adjusted depending on changing soil resistance and at the same time it prevents any
increase in depth of tilling in case of smaller soil resistance.
Set the depth of tilling by lever (1) as described in 'Power regulation of the lifting of the rear three-point hitch'.
Then start moving lever (2) in the direction shown by the arrow until the arms of the rear three-point hitch
start to rise slightly. Herewith, mixed regulation has been set. Move the adjustable stop (5) to l ever (2) which
has been set and lock it. At the end of each row, raise the tool connected to the rear three-point hitch on ly by
moving lever (2) to (e) position. To lower the tool to its operating position again, move lever (2) to the preset
stop.

When you switch on the electric installation with the key of
the switching box (I), the lifting device remains blocked
electronically - the lifting and lowering function is
deactivated; on the EHR-B control panel the diagnostic
LED (7) and the vibration dampening LED (11) shortly
light up - the system self-test is in progress. The lifting
LED (8) and the lowering LED (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.
F_02_164
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).
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.

Vibration compensator (damper)
F_02_168
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.
By moving the lever (1) to position (b) - STOP position you will immediately stop the movement of the three-point
