In the case of some materials (like plastics) it is recommended to cut a smaller
stack than maximum specified.
Danger of damage in case of incorrect use!
operator is fully responsible for any damages caused by incorrect use
of the machine!
the machine is designed only for purposes given in this manual.
1.2 Documentation
•This instruction manual is part of the product.
•The operating instructions are not a manual for repairing the machine.
•Only use original spare parts.
•The illustrations in the operating instructions may differ from the actual state of the
machine.
•The types of auxiliaries indicated in the operating instructions, such as oils, lubricants,
etc. refer to those available on the market at the time of publication.
•Always keep the complete technical documentation close to the machine.
•We recommend that you carefully read this user manual before using the cutter
1.3 Organizational measures / receipt of operating instructions
The manual contains special information about the cutter's safety devices. Keep
the operating instructions close to the work space and secure them against loss or
damage. In addition to the instructions, you must also follow the generally accepted
standards and applicable regulations for occupational safety and accident prevention.

2. SAFETY OF USE
The mechanical, electrical and electronic cutter assemblies were made
according to state-of-the-art solutions and generally accepted technical rules that
ensure safety in the event of a failure. Appropriate safeguards provide the operator with
the highest level of security.
The use of accessories or accessories that have not been mounted, delivered or
manufactured by the cutter manufacturer requires a special permission from the
manufacturer. Otherwise, the warranty becomes void and the manufacturer is not
responsible for any damage or injury.
This requirement also applies to spare parts used during the necessary repairs!
Repairs may only be carried out by employees who have been appropriately trained by
the cutter's manufacturer. In the event of repairs carried out by unauthorized personnel,
the warranty granted to the device expires and exempts the manufacturer from any
liability for injuries or damage.
•The machine warranty expires if the machine is modified by the user.
•Modification of the device by the user releases the supplier and the manufacturer
from any liability
Despite the measures taken, operating the machine by insufficiently trained staff or
trained in the wrong way can pose a danger.
Every person involved in the assembly, installation, operation, maintenance and
servicing of the machine must read the operating instructions, in particular the chapter
"Safety of Use".
Despite the obligation to read and understand the safety rules at the time of
installation of the new cutter, these rules should be reviewed periodically.
Possible consequences of improper handling:
•Danger to life
•Danger of injury
•Danger of damage to the machine
•Deterioration of the technical condition of the machine causing production
stoppages

maintenance and repair of the cutter must read the entire operating manual, in
particular the chapter "Safety rules".
2.3 Requirements for the operator's workplace.
The employer is obliged to create working conditions at the cutter workplace
that preclude the operator from slipping, slipping or falling due to poor ground
conditions, the way of routing the wires or the lack of convenient access!
2.3.1 Personal protection equipment
If necessary or if it results from the regulations in force, use the following personal
protective equipment:
Wear safety shoes
Wear safety goggles,
Use hearing protection,
especially when cutting fragile material
especially when cutting hard material
2.3.2 Permissible environmental and operational conditions
Operation of the machine is permitted in closed rooms

2.4 Expected risks when operating the cutter
DANGER!
The operator must operate the machine in good technical condition.
At the beginning of each work shift and after each knife replacement, check the
operation of the safety devices. By n ot checki ng the m, there is an increased chance
of bodily injury or damage to the cutter.
The cutter should be used by one operator at a time.
The cutter should only be used by fully trained operators.

2.5 Description and evaluation of residual risk
The manufacturertakes responsibility for the construction of the cutter in
order to eliminate the danger, although some risk elements during the cutting machine
operation are possible. Residual risk may result from incorrect behavior of the cutter
operator.
 Failure to follow the safety rules described in the operating instructions

 Using the cutter for other purposes than those described in the user's
manual

 Unauthorized persons, especially children, using the cutter


 Unauthorized alterations to the cutter

 Cleaning and lubrication of the cutter during operation

 Working with dismantled or defective safety covers/systems

 Manipulation within the drive units and moving parts of the cutter during
operation

 Checking the cutter's technical condition and performing servicing or
repairs with the cutting machine

 Checking transmission gears during operation
When presenting the residual risk, the cutter is treated as a device that was
designed and manufactured according to the state of the art in the year of its
manufacture, 2020.

2.6 Safety systems used in the cutter
• Two-button engagement - the cutter is operated using the two-handed cut start
system
• LED Safety Curtain - an optoelectronic device that creates a safety
curtain
• Control system - position control at the upper turning point of the knife and the
pressure beam.

2.8 Safe working rules
1. Operator(s) should be trained
• Be aware of the potential hazards that may occur when operating the cutter
• Clearly define activities which, under the conditions of a given plant, are or are not
the responsibility of the cutter operator and are reserved for designated authorized
persons, in particular as regards the removal of defects and repairs - including
electrical installations.
2. Cutter should not be used if:
• It is used contrary to its intended use and/or the cutting parameters
specified in the operating instructions would be exceeded
• The cutter is visibly inefficient
• Any covers of moving parts have been removed from the cutter
3. Checking Safety Devices:
• Checking the correctness of the protection devices:
- two-button operation (each time before starting work)
- LED Safety Curtain protective device (each time before starting work)
The above-mentioned requirements should be the subject of training and the
content of the station instructions!
11

2.9 Safety control
Periodic security check should be carried out in accordance with the law. These
provisions concern:
 accident prevention

 guarantee of efficient work and precision of operation

 eliminating production stoppages.
INFO
Following a maximum of 5 years of use, the following functions
should be carried out and the results should be documented.
 operation of the control function

 check the correct position of the knife

 control of the power supply of the cutter linear indicator

 operation of the safety curtain

 operation of the two-hand control function

 protection against continuous knife movement.
The above mentioned service should be ordered by the cutter manufacturer's
technical service.
3. TRANSPORT AND STORAGE
3.1 Packaging
3.1.1 Characteristics of the packaging
The transport packaging used is a disposable packaging.
The transport platform is made of wood, and the outer packaging is made of cardboard.
Inside the box the cutter and accessories are packed in anti-corrosion covers made of
plastic and oiled paper.
3.1.2 Removing the packaging
Used packaging should be removed in accordance with legal regulations applicable in
the country of the user.
12

3.2 Transport
The box with the machine should be transported in accordance with the
markings on it (fig.4). When using a forklift (Fig. 5a), make sure that the fork length is
suitable so that you can grasp the entire depth of the box.
