SAFETY INSTRUCTIONS FOR USERS

General safety regulations
zThe 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.
zBesides 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
zDo not wear loose clothing and free flying long hair.
zDuring all work use suitable (prescribed) means of personal protection (working boots, gloves,
goggles, etc.)
Starting the engine
zThe engine cannot be started by driving the tractor downhill.
zThe engine cannot be started by towing the tractor with another tractor.
zOnly 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!
zThe key in the switch box must be in the 'I' position.
zWhen 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!

SAFETY INSTRUCTIONS FOR USERS

Driving operatio
n
zHoses of the hydrostatic steering, brakes and fuel system must be checked and replaced if any signs
of damage are found. These are some examples of hose damage signs: - cracks on the hose surface,
releasing of pre-tensioning 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.
zDuring driving on roads with trailers and tools the brake pedals must be connected with a latch.
zThe brakes and steering must be in the perfect condition all the time.
zDriving downhill without an engaged gear is forbidden.
zSwitching the reversing lever at a speed over 10 km/h is forbidden.
zPay special attention when driving on a slope and muddy, sandy, icy or uneven ground.
zObserve the maximum specified inclination angle, i.e. 12°.
zRespect the total permissible weight of the tractor and trailer specified on the data plate of the tractor
or on the rear wheel mud-guard.
zDo not use the differential lock when driving into a bend.
zIt is forbidden to get into and out of a moving tractor.
zWhen driving the tractor with agricultural machines attached to the front three-point hitch, reduce the
driving speed to 15 km/h.
zWhen driving with machines attached to the rear hitches the load of the steered axle must not drop
below 20% of the current weight of the set. With the driving speed reduced to 20 km/h the load of the
steered axle may drop to 19% of the current weight of the set (set below 4.5 t) or to 18% of the current
weight of the set (set exceeding (4.5 t).
zDuring 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.
zDuring 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:
za narrow wheel gauge
zinappropriate tractor travelling speed
ztravel on the slope along a contour line or turning on the slope
zdriving through ditches, depressions, near edges of ditches, chuckholes, steep slopes or when driving
on edges of water courses and water areas
zdriving up the steep slope, risk of overturning the tractor back
zdriving 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
ztilting 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
zThe number of persons transported by the tractor must not exceed the number specified in the
technical certificate of the tractor.
zPersons that are not authorized to work with the attached implement must not stand between the
tractor and the hitched machine (implement).
zBefore 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!
zDuring recovery it is dangerous to stand near the towing rope.
zIt is prohibited to use the tractor axles (individual wheels) as a winch for releasing a sunken tractor.
zThe front hook should be only use to recover the entire tractor, i.e. without any trailer or another
attached implement.
zNever recover the tractor with reduced gears engaged.
zWhen pushing other vehicles (trailers, implements, etc.) with the tractor never insert free wooden
blocks or bars between the tractor and the pushed vehicle.
zIn case of use of the tractor for wrecking or towing purposes, use only the rear hitch.
zWhen towing the tractor, the reduction gear shift lever must be in the neutral position.
SAFETY INSTRUCTIONS FOR USERS
18
Leaving the tracto
r
zPark the tractor only on an even land and where not possible, support with a shim assy.
zDo not park the tractor with an attached implement in the lifted position.
zUsually 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.
zUse 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.
zBrake the tractor with parking brake before leaving tractor with running engine.
zWhen 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.
zBefore leaving the tractor, do not forget to secure the tractor by manual brake. Engaging a gear does
not secure the tractor against rozjetím (clutch is disengaged), remove the key from the switchbox and
lock the cabin.
With stopped engine only
zAll 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.
zBefore 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
zRefuel the tractor best after the end of work and with the engine stopped.
zDo not refill fuel up to the top of the fuel tank in summer. Wipe spilt fuel immediately.
zDo not refuel the tractor near open flame and do not smoke.
zDo not smoke and do not use open flame when inspecting the battery electrolyte level.
zMake sure that fire safety instructions are strictly observed in environments with an increased danger
of fire (hay-lofts, straw-stacks, etc.).
zThe tractors are not equipped with a fire extinguisher from the production plant.
