1. General information
Thank you for purchasing one of our machines, and we hope that you will be fully satisfied.
This guide provides instructions for the installation, adjustment, operation and
maintenance of the machine B10 ELECTRA in compliance with valid safety standards.
The information and data contained in this document subject to changes due to
further improvement of machinery. To eliminate any doubts, when differences are
detected, please contact N.KO Machines.
Never perform any operation on the machine before you read the instructions in the
manual and understand them. Major part of accidents that happen in the workplace are
due to the fact that the guidelines and recommendations contained in the manual are not
complied with.
The graphic symbols used in the manual are intended to emphasize the important
information regarding the safety and operation of the machine.
Attention :
Information important for the personal safety of the operating staff.
Important:
Instruction that needs to be observed to ensure the proper function of the machine.
2. Machine description B10 ELECTRA
Machine B10 ELECTRA is designed solely for the activities below:
B10 ELECTRA is designed solely for bevelling and fetch fettling of metal materials in the
workshop or in the production hall.
This includes manual and manually managed machine. The main feature of the machine
is the ability to machine flat and shaped workpieces, openings, and tubes. The
machining angle can be changed by replacing the milling head. B10 ELECTRA can
perform also the workpiece edge rounding. This application also requires a special tool,
see the text below.
Use the machine in the environment protected from rain, snow, and other adverse
weather conditions.

4. Tests
The machine for edges bevelling is tested in our test room.
During that test, the correct function of bevelling sheets and profiles by different types and
sizes, are tested.
5. Warranties
The B10 ELECTRA is provided by the seller with a guarantee that the article shall not
feature any material and production defects for a period of 12 months following the
delivery date.
The machine is provided with a 12-months' guarantee from the delivery date for the faultless
function of the article and the materials used.
The seller undertakes to make sure that any potential warranty defects are removed free of
charge and without undue delay so that the buyer is able to use the article the way they
desire. Should the buyer claim liability for warranty-unrelated defects, it shall reimburse the
seller for any expenses associated with that.
The manufacturer considers the guarantee invalid if:
• the machine is improperly used.
• used in conflict with national or international standards
• improper installation
• defective power supply
• severe shortcomings in maintenance
• unauthorised modifications or interventions
• other than the original or unapproved parts and accessories by the manufacturer are
used for that model;
• full or partial failure to follow the instructions in this manual
• extraordinary events, natural disasters or the like.

6. Safety regulations
Attention :
In order to prevent the injury observe the below instructions
Inspect the machine for mechanical and other damage prior to bevelling.
Commission the machine solely if the electricity supply cable is not damaged.
Check the supply cord regularly. In case of damage have it replaced in an authorised
service shop authorised to perform the such repairs. Contact your supplier.
Personal protection from injury
During the work use safety goggles, solid work footwear, hearing protection, suitable
head cover, e.g. safety helmet.
• Connect the machine in electrical network solely if the machine is in off position.
• Prior to each use, check the device and electricity supply cord for damage. Do not
use the machine in case of any damage.
• Do not use the machine in humid environment and protect from high moisture.
• Ensure good lighting at the workplace to prevent the risk of potential injury or
eyesight damage.
• Caution, the tool (milling machine) is sharp with the risk of injury. During the
replacement use safety gloves, never touch the miller which moves.
• The machined material must always be fastened and horizontal. Optimum
workpiece height is 900 mm above ground.
• During work pay attention to the electricity supply cable; it should be loosely placed on
the ground outside the worked material and other sharp objects.
• After work, disconnect equipment from the electricity supply.
• Do not overload the machine motor. The machine operates better if not overloaded.
• During work, hold the device by both hands.
• Attention is drawn to the injury hazard with hot metal shavings.
Important:
In case of damage have the machine repaired in an authorised service shop authorised
to perform the repairs. For more information on, contact your supplier.

10. Use
Important:
The device can be used solely if it is fitted with the original indexable inserts supplied by
our supplier, i.e. the device manufacturer. It includes four-sided indexable inserts. The
device can be fitted with 6 pieces of indexable inserts. It is prohibited to use other than
original inserts.
11.1 Setting the removal size
Attention :
During the adjustment operation, wear gloves and other personal protective
equipment. The operations must be carried out on the machine at rest and after
disconnecting from the power supply.
• Disconnect the machine from electricity supply.
• Release the setting arresting screws (fig.10.0.1 position F)
• Turn the guiding plate (fig.10.0.1 position G) for setting the reduction size. You can
read the setting on the scale (fig.10.0.1 position C). The scale is just indikative. The
final result bevel size can be little bit different according of the milling head you are
using.
• After setting, fasten both screws (fig.10.0.1 position F).
Important:
Maximum reduction is 10mm of bevel width (dimension P fig.11.1.1). The reduction can be
achieved in more steps. It depends on the material solidity. We recommend performing the
test.
Start with lower reduction and gradually increase the value until the work with the machine is
comfortable and the plates can achieve gradually reduction without increased vibrations. For
orientation setting, use the tables below.
We recommend administering the work log for recording the measured value and the
machining procedure.
10
Fig. 11.1.1
For orientation setting of the reduction size and the independent machining process, use
the setting tables for individual bevel angles.
Important:
The values in the table are calculated from point 0. Point is the point when the
miller touches the material edge for the first time. This point can be set by
gradual turning of the thrust plate (fig.10.0.1 position G) and placing to the
material edge.
45° - For full bevel (P=10mm) is required, turn the thrust plate by 40 revolutions
