SAFETY INSTRUCTIONS FOR USERS

General safety regulations
• The tractor may only be operated by a trained person that has a valid driving licence and has been
thoroughly acquainted with the operation and safety rules.
• Besides the safety instructions mentioned in the Operator´s Manual you are obliged to respect
generally valid safety and traffic rules of the country where the tractor is used.
Proper clothing
• Do not wear loose clothing and free flying long hair.
• During all work use suitable (prescribed) means of personal protection (working boots, gloves,
goggles, etc.)
Starting the engine
• The engine cannot be started by driving the tractor downhill.
• The engine cannot be started by towing the tractor with another tractor.
• Only start the engine from the driver's seat with the shift lever and reversing lever in the neutral
position, PTO switched off and the clutch pedal depressed.
Life hazard when starting by means of short-circuiting the starter terminals!
• The key in the switch box must be in the 'I' position.
• 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.
Caution! Electric shock hazard!
• Starting the engine when driving tractor downhill is forbidden.
• Starting tractor by means of towing with another tractor or vehicle is allowed only when the pull bar is
used.
SAFETY INSTRUCTIONS FOR USERS
17
Driving operatio
n
• Hydrostatic steering hoses, brake circuit including protective sheaths and fuel system must be
inspected and replaced if signs of damage are detected. Signs of hose damage include: cracks on the
hose surface, loosening of the hose connection tension, (which can be verified by easily removing the
hose from the connection) and mechanical damage to the hose. Hoses with a designated service life
must be replaced immediately on reaching the indicated service life.
• When driving on roads with trailers and tools, brake pedals must be connected with a latch.
• The brakes and steering must always be in perfect working order.
• Driving downhill when not in gear is forbidden!
• Reversing at speeds above 10km/hr is forbidden!
• Pay particular attention to the steering of the tractor on slopes and on muddy, sandy, icy or uneven
terrain.
• Observe the specified angle of slope accessibility i.e. Max. 12 °.
• Respect the total permissible weight of the combination as indicated on the tractor data plate or,
where applicable, on the rear wheel fender.
• Do not use the differential lock when cornering.
• Getting in and out of a moving tractor is prohibited.
• When driving the tractor with agricultural machinery towed using a front three-point hitch, reduce the
tractor speed to 15 km.h-1.
• When driving with machines towed on rear hitches, the load on the steered axle must not fall below 20
% of the instantaneous mass of the combination. When the travel speed is reduced to 20 km/h, the
load on the steering axle can drop to 19% of the instantaneous weight of the combination (for
combinations up to 4.5 t), and up to 18% of the instantaneous weight of the combination (for
combinations over 4.5 t).
• 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.
• 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).
SAFETY INSTRUCTIONS FOR USERS

Risk of the tractor overturnin
g
The risk of the tractor overturning is increased especially when the following is used:
• a narrow wheel gauge
• inappropriate tractor travelling speed
• travel on the slope along a contour line or turning on the slope
• driving through ditches, depressions, near edges of ditches, chuckholes, steep slopes or when driving
on edges of water courses and water areas
• driving up the steep slope, risk of overturning the tractor back
• 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
• 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
• The number of persons transported by the tractor must not exceed the number specified in the
technical certificate of the tractor.
• Persons that are not authorized to work with the attached implement must not stand between the
tractor and the hitched machine (implement).
• Before putting the tractor in motion make sure there is no person or obstacle in the driving direction.
Recovery, pushing
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!
• During recovery it is dangerous to stand near the towing rope.
• It is prohibited to use the tractor axles (individual wheels) as a winch for releasing a sunken tractor.
• The front hook should be only use to recover the entire tractor, i.e. without any trailer or another
attached implement.
• Never recover the tractor with reduced gears engaged.
• When pushing other vehicles (trailers, implements, etc.) with the tractor never insert free wooden
blocks or bars between the tractor and the pushed vehicle.
• In case of use of the tractor for wrecking or towing purposes, use only the rear hitch.
• When towing the tractor, the reduction gear shift lever must be in the neutral position.
