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

• Only start the engine from the driver´s seat with the clutch pedal fully 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

Driving operatio

• Hoses of the hydrostatic control circuit and the brake circuit, including protective sheaths, must be

inspected daily and replaced immediately 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

marked service life must be replaced immediately after reaching the indicated service life.

• The brakes and steering must always be in perfect working order.

• When driving on roads with trailers, brake pedals must be connected with a latch.

• Driving downhill when not in gear is forbidden!

• Pay particular attention to the steering of the tractor on slopes and on muddy, sandy, icy or uneven

terrain.

• Observe the maximum set angle of slope availability 12° with tractors with front drive axle.

• Respect the total permissible weight of the tractor and trailer specified on the data plate of the tractor

or on the rear wheel mudguard.

• Do not use the differential lock when driving into a bend.

• It is forbidden to get into and out of a moving tractor.

• 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.

• When driving the tractor with agricultural machines attached to the front three-point hitch, reduce the

driving speed to 20 [Km/h].

• 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, 3R 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

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

• Use the tow bar or rope fixed in the front hitch to rescue the sunken tractor.

Never use chains! There is a risk of death in case that the chain breaks!

It is dangerous to stay near the tow rope during the rescue operation.

• It is forbidden to use tractor axles (individual travel wheels) as a winch with extrication of the stuck

tractor.

• The front hitch is only used to tow or rescue the stand-alone tractor, i.e. without the trailer or another

additional device. More information in the chapter TRANSPORT USE.

Never rescue the tractor when reduced gears are shifted.

• When pushing another vehicle (trailers, semi-trailers, etc.) with the tractor, never use beams or bars

freely inserted between the tractor and the pushed item.

• 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.
