z The key in the switch box must be in the 'I' position.
z When heating the engine with the * electric heater first plug the power supply cord to the heater and
only then to the electric mains. After the end of heating first disconnect the heater from the electric
mains.
z Driving down a slope with the aim of starting the engine is not permitted.
z It is forbidden to put the tractor in motion using another tractor or vehicle with the aim of starting the
engine.
Driving operation
z Hoses of the hydrostatic steering, brakes and fuel system must be checked and replaced immediately
if any signs of damage are found. These are some examples of hose damage signs: - cracks on the
hose surface, releasing of pretensioning of hose connection (which can be verified by easy removal of
the hose from the connection) and mechanical damage of the hose. Hoses with indicated service life
must be replaced immediately after the expiration of the service period.
z The brakes and steering must be in the perfect condition all the time.
z During driving on roads with trailers and tools the brake pedals must be connected with a latch.
z Driving downhill without an engaged gear is forbidden.
z Pay special attention when driving on a slope and muddy, sandy, icy or uneven ground.
z Observe the maximum set angle of slope availability 12° with tractors with front drive axle.
z During aggregations of the tractor with machines pay attention to possible worsening of stability of the
aggregated unit which may be influenced by the connected machine.
z Respect the total permissible weight of the tractor and trailer specified on the data plate of the tractor
or on the rear wheel mudguard.
z Do not use the differential lock when driving into a bend.
z It is forbidden to get into and out of a moving tractor.
z When driving with machines attached to the rear hitches the load of the steered axle must not drop
below 18 % of the current weight of the set.
z When driving the tractor with agricultural machines attached to the front three-point hitch, reduce the
driving speed to 20 km/h.
z During aggregation of Zetor tractors with machines and implements with high tensile resistance when
the engine speed drops and the engine tends to stall, the 1R, 2R reduced gears must not be used for
the work with these machines
risk of shaft twist-off
Risk of the tractor overturnin

The risk of the tractor overturning is increased especially when the following is used:
z a narrow wheel gauge
z inappropriate tractor travelling speed
z travel on the slope along a contour line or turning on the slope
z driving through ditches, depressions, near edges of ditches, chuckholes, steep slopes or when driving
on edges of water courses and water areas
z driving up the steep slope, risk of overturning the tractor back
z driving with the trailer, semi-trailer or machine with the three-point hitch connection that lifts the centre
of gravity of the tractor or combination of vehicles
z tilting of trailers and semi-trailers
Not all the cases that can cause overturning of the tractor are listed. Pay attention to driving
of the tractor and be prepared to resolve situations which can threaten stability of the machine.
Transportation of persons, operation
z The number of persons transported by the tractor must not exceed the number specified in the
technical certificate of the tractor.
z Persons that are not authorized to work with the attached implement must not stand between the
tractor and the hitched machine (implement).
z Before putting the tractor in motion make sure there is no person or obstacle in the driving direction.
Recovery, pushing
z To recover a tractor that has sunk in mud use a tow bar or rope attached to the front hook
Never use chains! Rupture of the chain represents a danger of death!
z During recovery it is dangerous to stand near the towing rope.
z It is prohibited to use the tractor axles (individual wheels) as a winch for releasing a sunken tractor.
z The front hook should be only use to recover the entire tractor, i.e. without any trailer or another
attached implement.
z Never recover the tractor with reduced gears engaged.
z When pushing other vehicles (trailers, implements, etc.) with the tractor never insert free wooden
blocks or bars between the tractor and the pushed vehicle.
z In case of use of the tractor for wrecking or towing purposes, use only the rear hitch.
z When towing the tractor, the reduction gear shift lever must be in the neutral position.
Leaving the tractor
g
USER´S SAFETY INSTRUCTIONS
14
z Park the tractor only on an even land and where not possible, support with a shim assy.
z Do not park the tractor with an attached implement in the lifted position.
z Usually use the left-hand side tractor door when leaving the tractor. Look round whether any vehicle is
coming, that could jeopardize your safety when leaving the tractor.
z Use steps and handles when leaving the tractor. When leaving the tractor by the right-hand side door
pay attention being in space of shifting lever and hand throttle control.
z Brake the tractor with parking brake before leaving tractor with running engine.
z When leaving the tractor with tools connected in the front or rear three-point hitch, the three-point
hitch with these tools must be lowered to the lower position.
The tractor must not be leaved with the tools in the upper position in three-point
hitches.
z Do not forget to brake the tractor with parking brake (shift the gear), remove the key from key switch
and lock the cab before leaving the tractor.
z At tractor equipped with reversor gear, shift the reversor lever into forward drive position.
With stopped engine only
z All work connected with refuelling, cleaning, lubricating and adjusting the tractor or attached
implements may only be performed with the engine and moving parts of the tractor stopped except
functional checks of the brakes, hydraulic system and charging.
z Before removing the side plates of the hood it is always necessary to stop the engine. The tractor
engine can only run in a closed building or room if sufficient ventilation is ensured. Exhaust gases are
harmful for health.
Fire prevention principles

Tractors equipped with front end loader
Zetor Tractors in standard design are designed for utilization in agriculture and are not designed for special
purposes.
Tractors designed for operation within the European Union must be equipped, in case of using front end
loader, with a protective structure (FOPS - Falling Object Protective Structure) protecting drivers from
potential falling objects.
It is necessary to observe applicable local valid regulations in countries which are not part of the European
Union.
Two types of cab roofs are mounted to Zetor tractors.
1. Standard cab roof
2. Cab roof designed for tractors equipped with front end loader meeting the OECD code 10 (FOPS)
conditions.
Tractors ZETOR supplied already from production with front end loader are equipped with cab roof according
to point 2.
From safety reasons, series ZETOR tractors supplied without front end loader with standard roof pursuant to
point 1 must not be equipped or used with front end loader.
In case of additional front end loader assembly, it is necessary to equip tractor with cab roof pursuant to point
2.
Only front end loaders approved by ZETOR TRACTORS may be mounted to ZETOR tractor.
dditional assembly of front end loader approved by ZETOR TRACTORS can be done only by
authorized ZETOR service.
It is forbidden to use front end loaders unapproved of by ZETOR TRACTORS.
Not observing this instruction may cause serious accidents.
Carefully observe instructions for use supplied by the manufacturer of front end loader.
Principles for operating tractors equipped with front end loade
r
USER´S SAFETY INSTRUCTIONS
19
Carefully study operation manual supplied by the manufacturer of front end loader.
In case 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.
z The use of front end loader for transporting material at places accessible to the public is forbidden.
z 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.
z Observe local valid regulations at all times.
z A strict ban on transportation and lifting of people by means of loader is in effect.
z 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).
z Never leave the tractor standing with the loader in lifted position.
z 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.
z 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.
z 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.
z The loader may be used, maintained and repaired only by people who perfectly know the machine
and who are informed about potential risks.
z When driving on roads do not transport any material on the front end loader.
z 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.
z The manufacturer does not bear any responsibility for any potential damage incurred as a result of
changes conducted on the loader without their consent.
z 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.
z 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.
z Each working tool was reconstructed for the purpose of specific usage and has its own tolerance of
resistance and tightness.
z 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.
z 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.
z 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.
z Do not overload hydraulic parts if the load is too heavy or pistons are in end positions.
z Control the loader exclusively from driver's seat, if you are sitting on driver's seat.
z Do not leave the seat if you have not blocked any movement of controls.
z No people can be present in the working zone of the loader.
z When working with a lifted loader, mind electric and external cables etc.
z 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
o
USER´S SAFETY INSTRUCTIONS
20
Standard tractors Zetor do not provide sufficient protection for operation in forest terrain as, for example,
protection 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 pr
-tective equipment. The
supplier/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.

Connect h
draulic brakes of trailer or articulated
trailer to the quick couplings marked by an arrow.
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 nonswitched on/switched off gear pump of hydraulics.
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.

Position regulation of rear three-point linkage heave is a means of regulation with which the tools connected
in three-point linkage is kept automatically at constant height (position) to tractor. Shift lever (1) to front
position (d). Perform vertical adjustment of rear three-point linkage with a lever (2) in (b) range. Height
setting is smooth in the range of 1-9. With number 1, there are three-point linkage arms in lower position,
with number 9 in upmost position. Position (c) is a transport position, in which tools connected in rear threepoint linkage are heaved to maximum.
For transporting tools connected in rear three-point linkage always use position regulation.
fter lifting tools to transport position, close oil flow through hydraulics to stop by turning the
control of speed of three-point linkage lowering (3) in the direction of an arrow. If tools hinged in
three-point linkage cannot be lowered in transport position, check the position of the speed of
lowering control (3) - turn it against the direction of an arrow. If tools hinged in rear three-point
linkage are long and heavy, there can be blockage of three-point linkage arms in transport position
during transport. If lowering speed control (3) is permitted and still a tool it cannot be lowered, move
the lever (2) to floating position (c) for a short time and immediately return to the lowering range (b).
The arms of rear three-point linkage start dropping according to a set lever (2).
Power regulation of three-point linkage heave
NM13N015
Power regulation of three-point linkage heave is a means of regulation with which the tools connected in rear
three-point linkage is automatically vertically readjusted depending on the change in soil resistance.
Place lever (2) to (f) position. Shift lever (1) to (g) position, start tractor and by shifting lever (1) from (g)
position in the direction of an arrow, set the depth of oil cultivation (in (g) position, the depth of soil cultivation
is smallest).
As soon as you determine the depth of soil cultivation, the lever (1) must be kept in constant position (1) and
at the end of the row to always heave tool connected in rear three-point linkage by only shifting the lever (2)
to (e) position. By shifting lever (2) to (f) position, you will return tool back to working position.
If there is oscillation of rear three-point linkage due to variable soil resistance, this can be
limited by setting lower sensitivity of hydraulic system by turning the control (4) in the direction of an
arrow
Mixed regulation of three-point linkage heave

NM13N016
Mixed regulation of three-point linkage heave is a means of regulation with which the tools connected in rear
three-point linkage is automatically vertically adjusted depending on the change in soil resistance, while it is
prevented for the depth to grow in soil cultivation with smaller soil resistance. The depth setting of soil
cultivation is done with a lever (1) as is the case with Power regulation of three-point linkage heave. Shift
lever (2) then in the direction of an arrow to the moment, when three-point linkage arms start lifting lightly.
Mixed regulation is set by this. Tools connected in rear three-point linkage can be lifted only by shifting the
lever (2) to (e) position at the end of a row. Tool is returned back to working position by shifting the lever (2)
to original setting.

Accumulator battery must be always connected by a 'minus' pole to earth electrode and 'plus' pole connected
with alternator. Reversely connected accumulator battery will destroy the whole of semiconductor device of
alternator. When using auxiliary accumulator battery for starting the tractor, do not forget to connect 'plus' to
'plus' and 'minus' to 'minus'. If replacement of a part of charging circuit is done, disconnect a battery from the
earth electrode of the tractor by battery disconnector (-). Any incidental short circuits on clamps are
excluded.
With any manipulation or starter repair, it is necessary to disconnect the minus pole of the
battery and to shift all the levers including PTO shaft shifting lever to neutral position so as to
revent spontaneous start and endangering the life of a repairman
It is forbidden to start by short circuiting the clamps of starter. Start tractor only from driver's
seat.
Attention! When the engine is switched off, the engine control unit remains active for about
1 minute because of storage of operation data. During this time the supply of current from the
accumulator must not be interrupted. Do not disconnect the accumulator before this time expires.
Accumulator battery
Accumulator battery is located in a box on the left side of
the tractor. After unscrewing the screw marked with an
arrow, lid of box of accumulator battery can be opened
together with steps.
NM13N076
Battery disconnector
Accumulator battery is located under the cab on the right
side. Battery disconnector (1) is located on the right side
of the tractor in front of the cab.
a - Battery connected
b - Battery disconnected
If the tractor is put aside for a longer period of
time, it is necessary to recharge the accumulator at
least once in three months because of the battery self
discharge. When putting tractor aside we recommend
you to disconnect the accumulator by means of
battery disconnector.
NM13N77
Attention! When the engine is switched off, the engine control unit remains active for about
1 minute because of storage of operation data. During this time the supply of current from the
accumulator must not be interrupted. Do not disconnect the accumulator before this time expires.

E604
Keep accumulator battery clean, well attached to the vehicle. The attachment device must not however
deform the accumulator vessel. The level of electrolyte must be under the minimum level (mark line) marked
on a vessel with polypropylene batteries.
Do the refill only with distilled water!
1. First study the instructions manual enclosed to the battery when working with accumulator!
2. When working with accumulator, protect your eyes with either goggles or a protective shield!
3. Electrolyte is an alkali, handle it therefore with due care! Rinse the skin stained with electrolyte
and neutralize with soap and water, just like the stained clothing. Keep away from children!
4. When recharging from electrolyte hydrogen is released on electrodes, which makes an explosive
mixture when mixed with air. It is therefore forbidden to manipulate with open fire near accumulator!
5. An explosion may be caused by a spark incurring after disconnection or release of clamp with
engaged charging circuit!
6. Discarded accumulator is environmentally hazardous waste - when buying a new accumulator,
hand the old one over to a seller who will dispose of it free of charge.
7. Insufficiently charged battery can freeze in winter!
Alternator
It is accessible after hinging the bonnet away. Charging
check is indicated by a red control on the compound
dashboard device, which must go out after starting.
When repairing tractor by electric welding, all
the conductors must be disconnected alternator.

When washing and cleaning tractor protect alternator prior to penetration of water or oil!
You must not disconnect alternator from accumulator during operation!
lternator must not ever be put in operation with a disconnected conductor from of clamp '+B' and
connected clamp '+D'. Such condition when increasing the revolutions may cause an exceptionally
high alternator voltage which would damage semiconductors!
Never short circuit any clamp of alternator in operation!
lternator must not be over activated. There is a risk of semiconductors damage with this
intervention!
Mind the perfect electrical joint on connecting clamps and on perfect alternator grounding!
lternator must not be overpoled not even for a short time
