The following precautions are suggested to help prevent accidents

The best operator is the careful operator. Most accidents can be prevented by observing certain safety
measures. Before using the tractor, read the following measures and observe them to avoid accidents. The
tractor may only be operated by authorized persons who are properly trained for this operation.

Tractor

1. Read the operating and maintenance manual of the machine carefully before operating the tractor.

Insufficient knowledge of machine operation can lead to accidents.

2. For safe operation, use an approved protective structure and seat belt. Roll-over of a tractor without

a protective structure can result in serious injuries or even death.

Do not remove the roll-over protective structure (ROPS).

Always use the seat belt.

4. The laminated roof of the tractor cab does not provide protection against the breakthrough of external

objects with higher weight.

5. To avoid falling while entering and leaving the cab, keep the stairs and platform clean, free of mud

and oil.

6. Do not allow anyone other than the operator to ride on the tractor. There is no safe seat or approved

passenger seat on the tractor.

7. Replace any missing, illegible or damaged safety signs.

Keep safety signs clean, free of dirt and grease.

Tractor service

1. For your safety, keep the tractor in good operating conditions. An inadequately maintained tractor can

be dangerous.

2. Stop the engine before servicing the tractor.

3. The cooling system operates under pressure.

If the engine and its cooling system are hot, it is

dangerous to remove the cap.

Turn the cap slowly to the stop, then let the pressure escape before

removing the cap.

Do not smoke while refueling the tractor. Never refuel the machine near an open flame.

5. The fuel in the injection system is under high pressure and can penetrate the skin. Unqualified

persons must not disassemble or modify the fuel pump, injectors, nozzles or other parts of the fuel
injection system. Failure to follow these instructions may result in serious injuries.

To prevent fire or explosion, keep the battery and the cold start devices away from open
flames.

Do not change or modify anything on the tractor and do not allow anyone to change or modify
anything on the tractor or any part of the tractor or its function.

Tractor Operation

1. Before starting the tractor, apply the parking brake, set the PTO switch to the 'OFF' position, move the

hydraulic control levers to neutral, the remote control levers to neutral (if fitted), and the transmission
to neutral.

2. Do not start the engine or operate the tractor when standing next to the tractor. Always sit in the

driver's seat when the engine is running or when operating the controls.

3. Starter safety switch. A safety switch is mounted on the tractor to prevent the tractor from starting

accidentally. The tractor's starter system is connected via this switch, which only closes when the
brake pedal is depressed. On some models, the reverse lever and the PTO button must also be in the
neutral position to close the starter circuit. Do not by-pass the starter safety switch. If the starter safety
switch is defective, consult your Zetor tractor dealer/distributor.

4. Avoid accidental contact with the shift lever while the engine is running. Such contact can cause the

tractor to move.

5. Do not get off or get on the tractor while it is in motion.

6. Before leaving the tractor, stop the engine, remove the ignition key and apply the parking brake.

7. Do not operate the tractor in an enclosed building without adequate ventilation. Exhaust gases can

cause death.

8. Do not park the tractor on a steep slope.

9. If the power steering or engine stops working, stop the tractor immediately.
