1. GENERAL INFORMATION
1.1. Application
The BM-7 is a bevelling machine designed to mill edges of plates and pipes made of
steel or aluminum alloys.
The machine allows you to bevel workpieces with athickness of at least 1.5 mm
(1/16’’) to the maximum bevel width of 7mm (9/32’’) and,depending on the milling
head used, at the angle of 30° or 45°. The included milling head allows you to bevel
not only at the angle of 45° but also with a radius of 2, 3, 4, or 5 mm when used with
radius inserts. The minimum diameter of a hole to be machined is 35 mm (1-3/8’’).
Optional milling heads allow you to machine holes with diameters of at least
22.5 mm (7/8’’), and a sticker protects aluminum workpieces against scratches.

2. SAFETY PRECAUTIONS
1. Before beginning, read this Operator’s Manual and complete proper occupational
safety and health training.
2. Use the machine only in applications specified in this Operator’s Manual.
3. The machine must be complete and all parts must be genuine and fully operational.
4. The specifications of the power source must conform to those specified on the
rating plate.
5. Never carry the machine by the cord and never pull the cord because this may
damage it and result in electric shock.
6. Untrained bystanders must not be present near the machine.
7. Before beginning, make sure that the correct is the condition of the machine,
power source, power cord, plug, control components, and milling tools.
8. Keep the machine dry, and never expose it to rain, snow, or frost.
9. Keep the work area well lit, clean, and free of obstacles.
10. Never use near flammable liquids or gases, or in explosive environments.
11. Use only tools specified in this Operator’s Manual.
12. Never use tools that are dull or damaged.
13. Install the cutting inserts and milling head securely. Remove adjusting keys and
wrenches from thework area before connecting the machine to the power source.
14. Never use the machine in upside down position with the milling head facing up.
15. If the cutting edge of the insert is worn, rotate the insert in the socket by 90° or, if
all edges are worn, replace with a new insert specified in this Operator’s Manual.
16. Before every use, inspect the machine to ensure it is not damaged. Check whether
any part is cracked or improperly fitted. Make sure to maintain proper conditions
that may affect the operation of the machine.
17. Always use eye and hearing protection, non-skid footwear, and protective clothing
during operation. Do not wear loose clothing.
18. Do not touch moving parts or metal chips formed during milling. Prevent anything
from being caught in moving parts.
19. After every use, remove metal chips from the machine, especially from the milling
head. Never remove chips with bare hands. Clean the machine with a cotton cloth
without using any agents.

20. Cover steel parts with a thin anti-corrosion coating to protect the machine from
rust when not in use for any extended period.
21. Maintain the machine and install/remove parts and tools only when the machine
is unplugged from the power source.
22. Repair only in a service center appointed by the seller.
23. If the machine falls from any height, is wet, or has any other damage that could
affect the technical state of the machine, stop the operation and immediately
send the machine to the service center for inspection and repair.
24. Remove from the worksite and store in a secure and dry location when not in use.

3. STARTUP AND OPERATION
3.1. Installing and removing the cutting inserts
Unplug the machine from the power source, and place the machine upside down.
Unlock the lever (1, Fig. 2), and then rotate the sleeve (2) to lower it as far as possible
and access the milling head. Use the special wrench 3to loosen the roller, and then
use the screwdriver 4to unscrew the inserts. Next, clean the sockets, push the inserts
into the sockets, and then retighten the inserts and roller. The entire bottom of the
insert must be in full contact with the socket (5).
To change the cutting edge, unscrew the insert, rotate it by 90°, push into the
socket, and tighten. If all cutting edges are worn, replace the inserts with new ones.
Fig. 2. Installing the cutting inserts
Clean the threads once aweek and, if necessary, grease the fixing screws for inserts
with an agent (for instance copper paste) that will prevent the screws from blocking.

3.2. Installing and removing the milling head
Unplug the machine from the power source. To remove the milling head, unlock the
lever (1, Fig. 3) and unscrew the sleeve (2, 3). Through the hole in the body insert a
screwdriver 4into the spindle to lock the spindle, and then use the special wrench to
unscrew the milling head (5, 6).

3.3. Adjusting the bevel width
Unplug the machine from the power source. Next, loosen the lever (1, Fig. 5), rotate
the sleeve (2) so that the scale 3shows the required bevel width, and then retighten
the screw.
Fig. 5. Adjusting the bevel width
3.4. Adjusting the guide for bevelling with radius
Unplug the machine from the power source, and then in the manner described before
loosen the lever and rotate the sleeve to set the surface 1(Fig. 6) on the same height
as the end of the cutting edge 2. You can also use an optional radius insert positioner
to set the guide properly. Next, retighten the lever, bevel a test edge, and then readjust
the position of the guide if necessary.

3.5. Operating
Install the required milling head with cutting inserts, and set the required bevel width.
Next, connect the machine to the power source, and place the machine on the left so
that the milling head is not in contact with the workpiece (Fig. 7). The workpiece must
be stable and well fixed.
Fig. 7. Machine properly placed on a plate
Press and hold the ON/OFF switch to start the motor and wait a few seconds until
the machine reaches the maximum rotational speed. Next, press the machine to the
workpiece with both hands, slowly slide the machine toward the edge, and then slide
the machine according to the counter-rotation, that is from left to right.
Bevel in two passes. The bevel width should be set to a value that will allow the
feed of one meter per minute without significant effort.
Replace inserts before they become dull to prevent the motor from overloading.
Additionally, take periodic breaks during operation to prevent the motor from
overheating and damaging the windings.
After the work is finished, release the ON/OFF switch to turn off the motor, wait
until the rotation stops, and unplug the machine from the power source.
Clean the machine with a cotton cloth without using any agents.

3.6. Replacing the brushes
Check the condition of the carbon brushes every 100 operation hours. To do this, unplug
the machine from the power source, and unscrew the cover 1(Fig. 8). Next, loosen
the screw 2, pry off the spring holding the brush (3), and remove the brush (4). If the
length of the brush is less than 5 mm (0.2’’), replace both brushes with new ones.
To install brushes, proceed in reverse order. Make sure to place the terminal of the
brush wire 5between the washer 6and the terminal of the motor wire 7. After the
replacement, run the motor without load for 20 minutes.

4. ACCESSORIES
4.1. Radius insert positioner
Allows the guide to be set properly for bevelling with a radius of 2, 3, 4, or 5 mm.
Unplug the machine from the power source, place the machine upside down, and
then lower the sleeve to access the cutting inserts. Next, place the positioner from the
top (1, Fig. 9) so that the edge marked with a given radius is aligned with the edges of
three cutting inserts with the same radius (2). Finally, rotate the sleeve (3) so that the
guide makes contact with the positioner (4).
