Principles for operating tractors equipped with front end loader
Carefully study operation manual supplied by the manufacturer of front end loader.
In cas
e 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.
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 position
You will find more information in user's manual to front end loader.
Important notification: Work always safely and with consideration.

Zetor tractors used for work in the woods
Standard tractors Zetor do not provide sufficient protection for operation in forest terrain as, for example,
protec
tion against a fal-ling tree or branch on a cab or penetration of objects to a cab.
If Zetor tractor is utilized for forest work, a tractor operated within the European Union must be protected
against these risks.
It is necessary to observe applicable local valid regulations in countries which are not part of the European
Union.
To ensure this protection, it is advisable to conduct assembly of a specific protective structure, like for
example FOPS / OPS (Fal-ling Object Protective Structure / Operator Protective Structure), tested according
to standards for forest machines.
Only forest superstructures approved by ZETOR TRACTORS can be mounted to ZETOR
tractors.
In case of additional assembly of further tractor equipment for working in the woods, full responsibility is
borne by the supplier and manufacturer of the protective structure that all the safety regulations (e.g: OPS /
FOPS), all the conditions of homologation (e.g. the area of driver's view, lighting, parameters, permissible
weight etc.) are met, same as for the provision of due assembly of pro
-tective equipment. The
suppli
er/manufacturer of protective construction is also obliged to conduct all the necessary validation
(approval) steps required by the legislature of the country in which the tractor is operated.
Safety labels
