action) in case of non-comlying with the condition and recommendation;
- important information concerning proper exploitation of the tractor.
GENERAL REQUIREMENTS
• Familiarize yourself thoroughly with the servicing instruction before starting up the tractor because
unsufficient knowledge of this servicing instruction may lead to occurence of situation being danger for
the operator and aggregate.
• The tractor should be operated by the driver possessing appropriate driving licence and familiar with the
rules of proper operation and e ploitation of tractors and farm machines (tools).
• The tractors ZEFIR have the safe cab of the type S-11 not adapted for transportation of a passenger
on public roads. It is forbidden to transport a passenger on public roads.
RULES OF SAFE OPERATION OF THE TRACTOR
• Carry out visual inspection of the tractor, its connection and hitch devices, the aggregated machine (tool)
before starting work and do not start work without having made sure of their completeness and
proper connection.
• Apply always reliable joints (original pins and their protection) to attached machines.
• Regulate the three points suspension system /TPSS/, so that the machines (tools) suspended on it in
transportation position, will be rigidly connected with the tractor.
• Perform carefully all actions of servicing of the tractor and its equipping and especially braking and
steering systems so that they will always be in a perfect technical state because it is decisive of your
security.
• Perform all actions connected with cleaning and washing, preparing for work and technical servicing
when the engine is not running and the tractor is braked with the parking (manual) brake.
• There is pressure in the cooling system during running of the engine ( there is the pressure valve in the
cork of the radiator).Therefore do not unscrew the cork during running of the engine, and when
unscrewing do it very slowly and carefully in order to reduce pressure gradually in the system.
• Keep paricular care during removal of hot fluid from the cooling system, of oil from units of the driving
system and steering system in order not to be e posed to scalding.
• Do not approach the tractor with open fire (even with lighted cigarette) during filling the tanks with fuel,
servicing of fuel system and checking of batteries.
• Do not conduct any modifications and do not install parts or assemblies which introduce changes in the
structure of the tractor without consultation with the manufacturer of the tractor.
RULES OF SAFE WOR WITH THE TRACTOR
• You must instal all shields before starting the engine or work with the tractor.
• Set the gear-change lever in the position N before starting the engine.The lever for drive switching-on
/ PTO (power take off)/ should be in the position “PTO SWITCHED OFF”.
• Do not start the engine and do not operate levers (pedals) of the steering when you are not taking the
operator’s place.
• Release the parking brake before bestiring and make certain whether the people helping with servicing
or aggregating are not in dangerous situation especially whether they are not between the tractor and
the aggregated machine (tool). Warn these people about the intention of moving by means of sound
signal.
• Children must be kept away from the tractor and farm machines.
• Do not leave the tractor when it is on the move.
• Stop the engine and switch on the parking brake before leaving the cab.
• Do not work with the tractor in closed spaces without intensive and efficiently acting ventilation because
e haust gases may be a lethal danger.
• If the engine or the steering system turn out to be non-operational during driving, interrupt driving,
because the tractor, in such situation, requires substantial forces applied to the steering wheel in order to
steer it.

• Do not work and do not allow your helpers to work under the machines (tools) lifted on the lift of the
tractor.
• Do not leave, in top position, machines (tools) suspended on the lift during longer stoppages of the
tractor.
• Install weights of the front a le in case the wheels of front a le of the tractor lose contact with the ground
after lifting the machine (tool) aggregated on the TPSS / three points suspension system /. If, despite
this, the front wheels of the tractor do not obtain sufficient contact with the ground (allowing free
manoeuvring with the aggregate), do not work with such machine or tool.
• Make certain before lifting or lowering the machine (tool) suspended on the TPSS and also during
making of turns, if it does not come to collission with cooperating people or subjects threatening with
occurrence of dangerous situation.
• Do not work using jointed and telescopic shafts without shields for drive of machines and tools from
PTO of the tractor.
• Switch off the PTO drive during checking (during stoppage) of the aggregated machines (tools) driven

recommended (admissible) velocities. You must also use counterweight on the rear
suspension system.
It is inadmissible to utilize the front leader without counterweight suspended on the rear
TPSS / three points suspension system /.
REMEMBER! – it is your tractor.
If you use it incorrectly, it may be dangerous for you, strangers and environment. Don not work
with fittings non-designated for cooperation with the tractor !
DRIVING THE TRACTOR
In order to avoid dangerous situations (especially threatening with overturning the tractor) keep care and
prudence during driving the tractor. Adapt speed to conditions prevailing on the road, especially during
moving on uneven (hilly) land,while crossing ditches,on slopes and bends (turning back points). Do not take
sharp turns under full load and with high velocities of the transport.
SAFETY RULES DURING PERFORMANCE OF TRANSPORT WOR S
During moving on roads - also non-public roads you must absolutely observe road traffic provisions
binding in the country on the area of which the tractor is moving.
• During moving on public roads the tractor should be equipped with the warning reflective triangle and
on the tractor there should be installed the triangular board distinguishing slow-moving vehicle. In
case the tractor is moving in aggregate with a trailer or machine, the triangular distinguishing board
should be installed on the trailer or machine (according to the provisions).
• Do not drive the tractor (with a trailer, machine or tool) without operational braking installation as well as
lighting and signalling installation in vehicles of the unit or with non-connected installation of the trailer
(machine) with the tractor. It threatens with an accident.
• Do not leave the trailer (machine, tool) disconnected from the tractor on the public road. In case of failure
turn aside onto the shoulder, set up the warning reflective triangle (equipment of the tractor and trailers)
in the way consistent with the provisions and switch on the standing (parking) lights.
• Do not leave the tractor (aggregate) on slopes. In case of necessity lower the tool, switch on the first
gear , switch on the drive of the front a le (position „switched on”) and the parking brake.
• Do not e ceed the speed of the tractor aggregate over 30 km/h, do not drive down the slope when the
engine is switched off, “in neutral” or when the clutch pedal is pressed. It threatens with danger.
• Do not transport people on trailers and machines (tools). It is forbidden !
• Take care so that the pedals of independent brakes will be connected and their action will be
simultaneous.
• Do not drive the unit of the tractor and trailer when it is lighting the red lamp signalling unsufficient
pressure in the braking system of the trailer (trailers). This can prevent effective braking.
• In case of aggregating the machine on the rear TPSS we cause obturation of the rear combined
lights.Additional combined lights must be applied on the machine.

• Observe absolutely road traffic provisions during towing the tractor. It is admissible to tow the tractor with
non-running engine and with operational steering system, with speed not e ceeding 10 km/h.
WOR OF THE TRACTOR WITH THE SWITCHED ON POWER TA E OFF SHAFT (PTO)
• During work with machines (tools) driven by the PTO shaft, in case of necessity of inspection of the
machine (its disconnecting), before leaving the cab make sure if the PTO shaft is not rotating.
• During work with machines (tools) driven by the PTO shaft persons staying in the vicinity of rotating
units or elements of the machine shoud not be dressed with loose-fitting clothes because it may be the
cause of occurrence of hazard.
• During work with stationary machines driven by the PTO shaft, always switch on the parking brake, block
the rear wheels in front and in the rear and set up front wheels as for driving straight on.
• Do not perform actions connected with washing, regulation or servicing of machines (tools) driven from
the PTO shaft when the engine is running.
• Always apply roof shield and when the PTO shaft is not used, place the protective cap onto the ending of
the PTO shaft.
• Do not use shafts for driving of machines without complete structurally designed shields.
• Always use properly selected (in dependence on the magnitude of torque of the driven machine which
must be transmitted)jointed and telescopis shafts. Value of moment in w Nm is usually given on the
shield of the PTO shaft.
RULES OF FIRE SAFETY
• Do not add, on no account, gasoline or mi tures to diesel fuel oil because it may considerably increase
hazard of ignition or e plosion.
• Always turn off tightly the plug of fuel filler to the tank.
• Do not fill fuel when the engine is running.
• Do not smoke cigarettes during filling fuel neither during servicing of fuel system.
• Do not fill the whole volume of the tank with fuel. Always leave small space for e pansion of fuel.
• Always refill fuel after finished work in order to reduce formation of steam condensate in the tank.
• Do not store engine fuels and lubricants in distance smaller than 3 m from the place of permanent
parking of the tractor. Equip this place with operational fire-fighting equipment.
• Keep care during repairs connected with welding.Clean the place of repair so that the focus of fire will
not be formed during work.
• Take care of tightness of the e haust system and so that the e haust system will not be contaminated,
especially from the outside, with inflammable substances.
• Do not allow formation of leaks from fuel and hydraulic installation.
• Equip the tractor with fire e tinguisher GP-1X, BC-DB, or e tinguisher of similar type and fasten it in the
grip.
RULES OF SAFE WOR ON A SLOPE
During work on a slope or sloping fields quantity of fuel in the tank should occupy minimum of 1/4 of
its capacity so that the possibility of formation of air pockets in the fuel systems will not take place.
If it is possible, avoid driving the tractor across the slope (- the desired direction – uphill and downhill the
field). If the work is to take place across the field you must additionally:
• use the widest wheel track,
• conduct returns in the direction of the hill,
• lift the tool not higher than it is necessary to conduct the manoeuvre (e.g. return),
• check if the pressure in wheels is identical,
• reduce velocity to minimum during returns,
• during use of reversible plough start ploughing from the top of the hill; in this way the wheels from the side
of the hill top will go in the furrow – reducing the angle of inclination of the tractor.
