instruction manual in detail. The manual mustn’t be read in haste. By doing
so, the user can cause machine failure or threaten health or life of others.
It contains basic rules of conduct and the correct way to operate the
machine as well as instructions, which should be followed at all times to
ensure own safety, flawless operation of the machine, lower operating
costs as well as reliability and durability of the machine. Individuals
operating the machine must be trained, possess adequate qualifications
and read the manual carefully. Machine users must learn about the
intended use of all machine components and how to use them. Follow the
provisions of occupational safety, pay special attention to warning signs,
which failure to follow results in danger to both operators as well as the
machine. The cultivation unit for strip till is intended for usual work in the
field. The Producer does not bear responsibility for damage to the machine
resulting from use other than intended. Warranty is lost following own
repairs or modifications to themachine, negligence and useof non-original

machine is working.

11 | P a g e
5. Intended use of the machine
The machine is to be used in land cultivation and any other way of using it, for
instance, as a means of transport, may lead to injuries to the body or even death.
The user is solely responsible for the risk associated with improper use of the
machine. The machine is to be used only in perfect condition. All faults must be
removed immediately, especially those that might affect occupational safety. You
must follow the applicable OHS regulations issued by industry organizations and the
generally accepted regulations of occupational medicine, traffic safety and technical
safety. The machine can be maintained, used and repaired only by individuals, who
have read the user manual, know how the machine works and have been informed
about possible threats. The user manual is an integral part of the machine and must
be kept in an easily accessible place. If the machine is resold, the new owner should
also receive the user manual. Original accessories and spare parts have been
designed uniquely for this machine. Installation and use of non-original parts may
cause unfavourable construction changes and affect safety of people and machines
in a negative way. The producer does not bear responsibility for damage resulting
from use of unauthorized parts.
6. Personnel qualifications
In order to avoid accidents, all people using the machine must meet the basic
requirements:
•understand the workings of the machine;
•recognize possible threats and prevent them from occurring;
•have proper physical attributes required to handle the machine;
•perform work using the machine in a safe way described in the manual;
•understand the user manual and use information contained herein;
•have experience in driving vehicles;
•have a driving license if the machine is to be used on public roads;
•apprentices can use the machine only under supervision;
•people operating the machine must have adequate educational background.
It is the duty of the owner to:
•train and instruct operators;
•give the user manual to the operator and make sure that he or she
understands information contained therein;

12 | P a g e
Machine operators must have appropriate knowledge so they can cover the following:
•maintenance;
•use;
•finding and removing faults and failures;
•transportation on public roads;
•adjustment and setting of the machine.
6.1. Mounted and trailed equipment
1. Before attaching/detaching mounted equipment to the three-point linkage, the
lever of the hydraulic lift (of an agricultural tractor) must be left in the position
that makes it impossible for the hydraulic system to start on its own.
2. When using the three-point linkage, you must use matching categories of the
tractor and the seeder (optionally categories 3 and 4 of the linkage are
available).
3. You must be especially careful in the working section of the three-point linkage.
You can get crushed or suffer cuts. No one should stay between the Czajkowski
ST unit and the PS attachment, or the precision seeder, while the unit is
reversing towards the attachment.
Fig. 2. Pictogram NK0001
4. While operating the three-point linkage from the outside it’s forbidden to stay
between the tractor and the Czajkowski STK unit, the PS seeder and the
precision seeder.
5. When the machine is in the transport position, pay attention to the protruding
elements (hooks, rods, cables) of the three-point linkage (if neither the PS
seeder nor precision seeder are attached to the unit).
6. Secure the machine against unwanted movement and rolling with anti-roll
chocks.
7. If you’re mounting equipment with the use of a drawbar, pay attention to the
sufficient movement scope of the drawbar at the mounting point.

13 | P a g e
6.2. Fire safety regulations
•The tractor must be equipped with a fire extinguisher placed in the holder;
•Fuel and hydraulic leaks from the machine and the tractor must be prevented;
•Smoking is forbidden when fuelling up and operating the fuel system of the
tractor;
•Fuel cap of the tractor must be tightly closed;
•The engine must be turned off when fuelling up;
•Flammable materials mustn’t be stored in the vicinity of the machine.
6.3. Hydraulic system
Hydraulic system is a high-pressure system. The escaping liquid may get through the
skin and cause serious harm. If you suffer any injuries, immediately see a doctor. The
hydraulic system of the machine can be dangerous to humans and the machine if it’s
incorrectly operated.
It's important to remember that:
•It is a high-pressure system;
•Hydraulic hoses can be connected to the tractoronly after the hydraulic systems
of the tractor and the equipment have been depressurised.
•Leaking oil may cause fire or pose a threat to health.
•All hydraulic cables (hoses, quick release couplings) must be checked regularly
for visible damage of tightness. If damage is noticed, the damaged elements
must be replaced at once.
•Sockets and plugs of hydraulic connections must be marked to eliminate
operational errors.
•Hydraulic hoses must be replaced not later than after 6 years.
•The hydraulic system is equipped with pressure accumulators.
•It’s forbidden to modify pressure accumulators. Before starting maintenance
operations, it’s necessary to depressurize the hydraulic system. After emptying,
there’s gas pressure in the tank.

14 | P a g e
7. Transportation on public roads
•Before transportation, the working elements of the machine should be properly
folded and lifted according to the producer’s instructions.
•During transport, the width of the folded machine must not exceed 3 m and the
height 4 m. You should also remember about the appropriate transport
clearance.
•Take into account the prevailing road conditions while driving.
•Always abide by allowable dimensions and weights.
•The tractor must have proper weight, so it can provide proper handling and
efficiency of braking.
•During transportation, it’s forbidden to transport people and things on the
machine.
•Before driving, check whether the headlights and light signals are connected
and work correctly.
•It is forbidden to drive on public roads with the filled tank.
•It is forbidden to drive the machine on public roads over 25 km/h.
8. Warranty claims
Warranty claims must be sent to the Service Department of the Czajkowski Maszyny
Company.
9. Danger to children
Children in the close vicinity of the machine are subject to exceptional danger. It’s
forbidden for children to approach the machine. Before leaving the cabin, you must
turn the tractor engine off and remove the keys from the ignition so children cannot
start the machine by accident. Before starting work, you must check if there aren’t any
children in the danger zone. Always secure the machine where it’s parked.

15 | P a g e
10. Warning pictograms
Warning pictograms on the machine are very important when it comes to safety,
because they inform about possible threats in dangerous places. If there aren’t any
warning pictograms on the machine, the risk of serious and deadly injuries is increased.
Damaged or unreadable warning stickers must be replaced immediately. You must put
proper warning stickers on spare parts. Clean any dirty warning stickers. New warning
pictograms can be purchased from the producer.
Pictograms have the following meaning:
NK0001 –It's forbidden for people to stay between the machine and the tractor while
attaching them
NK0002 –Fold the drawback support after attaching the machine to the tractor
