1.2 Testing
The bevelling machine is tested in our technical test room.
During the test, correct functioning of the electric system, and correct functioning of the
bevelling plates and profiles of different types and sizes are checked.
1.3 Guarantee
The Seller provides a guarantee for fault free material and workmanship of the
UZ 18 Hardworker bevelling system for a period of 5 years from the delivery date of the
goods.
A guarantee for correct functioning of the goods and materials used is provided for a period of
5 years from the delivery date of the goods.
The Seller undertakes to remove all possible defects covered by the guarantee, free of charge
and without undue delay, so that the Purchaser can use the goods appropriately. Should the
Purchaser make a claim based on a liability for defects not covered by the guarantee, s/he

The guarantee period is suspended on the day when the Purchaser notifies the Seller of a
defect covered by this guarantee, due to which the Purchaser is unable to use the goods and
makes a claim based on the liability for defects covered by the guarantee granted, until the
date when the defect is removed by the Seller.
The guarantee does not cover natural and normal wear of the goods and defects caused by
incorrect use of the goods contrary to the training and documentation provided. Further, the
guarantee does not cover defects due to overloading of the goods or those resulting from
incompetent interference in the goods or incompetent repair or modification. Incompetent
interference, repair or modification means any interference, repair or modification executed
contrary to the training or documentation provided, or executed by any person other than the

- improper use of the machine;
- use contrary to national or international standards;
- incorrect installation;
- defective electrical power supply;
- serious maintenance shortcomings;
- incompetent modifications and/or interferences;
- usage of unoriginal or incorrect spare parts and equipment for the given model;
- full or partial infringement of instructions;
- exceptional events, natural or other disasters.
1.4 Identification data
The identification data of the bevelling machine are indicated on the aluminium CE label

SAFETY
2.1 Safety recommendations
Attention:
Read the following instructions carefully to prevent personal injuries and/or property
damage.
- Never try to operate the machine unless you have carefully acquainted yourself with its
functions. If after having read this manual carefully and fully you are still in doubt, contact
the N.KO company.
- Make sure that all technical workers entrusted with operation and maintenance of the
machine are fully acquainted with all the relevant safety recommendations.
- Transport and installation of the machine can only be done by specialized workers in
conformity with the instructions in this manual.
- Before starting the machine, the operator must check that all safety devices are functional
and all safety guards are in place.
- Never use the machine for any purposes not indicated in this manual. Never process
products other than what is indicated here.
- If you want to use the machine for purposes other than those defined, ask the N.KO
company for approval.
- The machine supply voltage values are dangerous; check whether all connections are
executed correctly. Never perform any maintenance of the machine or replacement of its parts
if the machine is connected to the electrical power supply. Never install any branches on the
electrical connections.
- Replace defective parts with those recommended by the manufacturer. Never use non-
original spare parts.
- Never wear clothing or jewellery which may get caught in the moving parts. It is
recommended to use protective clothing, non-slip shoes, and protective goggles.
Important:
If during the machine lifetime any defects occur which cannot be removed with the help
of this manual, it is advisable to ask the N.KO company to resolve the problem as soon
as possible.

2.2 Safety labels
Safety labels are placed on the bevelling machine to protect the operators.
Meaning of the labels:
This label is placed on the electrical panel of the bevelling machine, and indicates the
presence of high voltage.
Do not remove the label from the machine.
2.3 Qualification and protection of operators
The employer is obliged to inform the operators about safety standards; moreover, he must
ensure their observance and make sure that the working area is large enough and well lit.
The term “operator” means any person who carries out installation, operation, adjustment,
maintenance, cleaning or repairs of the machine.
Attention:
Before starting work with the machine, make sure that the operator understood the
content of the operator manual.
Attention:
The operator must always:
1. Check that all safety guards are in place and safety devices are functioning before
starting the machine.
2. Avoid wearing clothes or jewellery which may get caught in moving parts.
3. Wear approved protective clothing, such as non-slip shoes, ear protectors and
protective goggles.
4. Apply safety standards; see that they are observed at all times; and, if in doubt, consult
this manual again before taking any measures.
5. Contact the machine supplier if unable to remove defects causing its malfunction, if
there are defective parts or the running is abnormal.

2.4 Safety devices
The machine is equipped with safety guards to isolate the zones potentially dangerous to the
operators. The guards are attached to the frame or screwed to with the machine housing. They
can be dismounted with suitable tools. This operation may be necessary during certain
maintenance activities. An acrylic glass guard is mounted in front of the cutting tool
(position A. Fig. 2.4.1) to protect the operator during bevelling.
Attention:
The guard can only be removed if the machine is at standstill, with the power supply
plug disconnected. Never use the machine without the safety guards in place.
The machine is equipped with a mushroom emergency button. This red button overrides all
other operations and stops the machine immediately (position B, Fig. 2.4.1).
Use the emergency button:
- in case of immediate danger or mechanical accident;
- for short interventions, if the machine is switched off, to perform maintenance in this state;
- the button is also equipped with a lock to prevent start of the machine by an unauthorized
person.

2.5 Residual risks
The machine has been designed and manufactured with all devices and equipment for health
protection and the safety of operators.
The machine is fully covered to minimize the risk of contact with movable parts.
There is, however, one risk remaining:
As mentioned above, the working zone is protected as much as possible; however, it has to
remain open partly to enable feeding of the material to be bevelled.
Therefore, there is a risk of the operator putting his/her fingers into the zone in which both the
cutting tool and the work piece holder are.
Attention:
Always keep your hands as far from the cutting zone as possible.
Attention:
Always apply the safety regulations contained in this manual and ensure their
observation and the elimination of all residual risks.
TECHNICAL SPECIFICATIONS
3.1 Machine description
The bevelling machine model UZ 18 Hardworker has compact dimensions. One of its main
features is the adjustable bevel angle and automatic material feed.
The machine is equipped with a hardened cutting tool, sturdy work piece holder, direct-
reading scale used for setting values (bevel size and angle), and a special guide facilitating the
loading of material.
These characteristics enable easy setting of the working angle without exchange of the lower
cylinder, and precise regulation of the bevel angle.
The UZ 18 Hardworker bevelling machine is reliable and requires minimum maintenance.
