34. All works connected with refilling of fuel, cleaning, lubrication and adjustments of the tractor or suspension machines may only
be carried out with engine stopped and stopping of movable parts of the tractor, except check of function of brakes, hydraulics
and recharging of the battery.
35. Before removing the bonnet it is always necessary to stop the engine. In closed rooms the engine of the tractor may run only
if sufficient ventilation is provided. Exhaust gases are harmful for human health.

SAFETY INSTRUCTIONS FOR THE USERS
TRACTORS EQUIPPED WITH FRONT END LOADER
Zetor Tractors in standard design are designed for utilization in agriculture and are not designed for special purposes.
Tractors designed for operation within the European Union must be equipped, in case of using front end loader, with a protective
structure (FOPS – Falling Object Protective Structure) protecting drivers from potential falling objects.
It is necessary to observe applicable local valid regulations in countries which are not part of the European Union.
Two types of cab roofs are mounted to Zetor tractors.
1. Standard cab roof
2. Cab roof designed for tractors equipped with front end loader meeting the OECD code 10 (FOPS) conditions.
Tractors ZETOR supplied already from production with front end loader are equipped with cab roof according to point 2.
From safety reasons, series ZETOR tractors supplied without front end loader with standard roof pursuant to point 1 must not be
equipped or used with front end loader.
In case of additional front end loader assembly, it is necessary to equip tractor with cab roof pursuant to point 2.
Only front end loaders approved by ZETOR TRACTORS may be mounted to ZETOR tractor.
Additional assembly of front end loader approved by ZETOR TRACTORS can be done only by authorized ZETOR
service.
It is forbidden to use front end loaders unapproved of by ZETOR TRACTORS.
Not observing this instruction may cause serious accidents.
Carefully observe instructions for use supplied by the manufacturer of front end loader.

SAFETY INSTRUCTIONS FOR THE USERS
PRINCIPLES FOR OPERATING TRACTORS EQUIPPED WITH FRONT END LOADER
Carefully study operation manual supplied by the manufacturer of front end loader.
In case of discord of Principles for operating tractors equipped with front end loader and operation manual for
front end loader, which was supplied by the manufacturer of front end loader, the wording listed in operation
manual supplied by the manufacturer of front end loader shall apply.
- The use of front end loader for transporting material at places accessible to the public is forbidden.
- The use of front end loader for transporting material in places inaccessible to the public is possible only in a limited way. In
such case, instructions in user’s manual supplied by the loader manufacturer must be observed.
- Observe local valid regulations at all times.
- A strict ban on transportation and lifting of people by means of loader is in effect.
- No matter whether the front end loader is loaded or empty, no-one may stand in front of the loader if it is in lifted position. When
driving with a lifted loader, there is a risk of load transported by front end loader falling (there is a risk of disrupting the balance
of the tractor).
- Never leave the tractor standing with the loader in lifted position.
- If it is necessary to open the bonnet of the engine at intervention, disconnect the front end loader first or secure hydraulic rollers
of front end loader by metallic props designed for this purpose.
- Hydraulic circuit of the front end loader is designed in such a way to endure the maximum operation pressure of 20 MPa (200
bar). Do not do any changes on couplers of hydraulic circuit hoses.
- Any front end loader ZETOR mounting without observing the recommendation of ZETOR TRACTORS valid to the day of pur-
chase revokes the validity of guarantee for the whole of supply.
- The loader may be used, maintained and repaired only by people who perfectly know the machine and who are informed about
potential risks.
- When driving on roads do not transport any material on the front end loader.
- It is necessary to observe special instructions related to accidents prevention and general rules related to technical safety, la-
bour medicine, labour hygiene and regulation defining operation on roads.
- The manufacturer does not bear any responsibility for any potential damage incurred as a result of changes conducted on the
loader without their consent.
- Do not ever adjust the front end loader by yourselves and do not use the adjusted front end loader without prior ZETOR´s ap-
proval. The loader may become dangerous as a result of not observing these instructions. ZETOR TRACTORS shall not be
held responsible in case of any damage or injury.

19
SAFETY INSTRUCTIONS FOR THE USERS
- Use front end loader without additional weights on the tractor (danger of mutual contact). The load of front and rear drive axle
must not exceed the maximum permitted load listed in the manual. The use of front end loader requires mounting of counter
weight in the rear part of the tractor.
- Each working tool was reconstructed for the purpose of specific usage and has its own tolerance of resistance and tightness.
- It is forbidden to use front end loader for cultivating soil and stubbing. Such work needs to be done with a special tool, front end
loader is not designed for doing this.
- Using controls which would set the loader into motion without driver holding the gear shifting lever is strictly forbidden and re-
sults in installation not meeting the prescribed standard.
- To penetrate the loaded material, better use the kinetic energy of the tractor rather than pressing force which causes higher
strain of both the loader and the tractor.
- Do not overload hydraulic parts if the load is too heavy or pistons are in end positions.
- Control the loader exclusively from driver’s seat, if you are sitting on driver’s seat.
- Do not leave the seat if you have not blocked any movement of controls.
- No people can be present in the working zone of the loader.
- When working with a lifted loader, mind electric and external cables etc.
- Loader/tractor set needs to be parked on a horizontal and solid base, the arms of the lifting device must be set in the lower po-
sition. After using the front end loader, park the tractor and lower the tool to the ground.
You will find more information in user’s manual to front end loader.
Important notification:
Work always safely and with consideration.
