3. STARTUP AND OPERATION
3.1. Preparing
3.1.1. Adjusting the bevel width and angle
Before starting, set required bevel width and angle. First, with power cord unplugged
from the power outlet, set the milling head penetration to zero. To do this, loosen the
lever (Fig. 2) and rotate the adjusting knob to decrease the penetration of the milling
head into the workpiece by setting the indication ‘0’ on the width pitch.
Fig. 2. Adjusting the bevel width and angle
All safety precautions must be closely observed.

SM-BM-21S
To change the angle of the bevel, use the supplied 6 mm hex wrench to loosen
two side screws. Then, turn the guide in a way to set the required angle on the angle
pitch and tighten the screws afterward.
To adjust the bevel width, use the adjusting knob, proceeding as described before.
The width pitch is only an estimate, because the bevel width varies with angle. For
example, for the angle of 10° the maximum width ‘b’ (Fig. 1) is approximately equal
18 mm (11/16’’), while the width pitch indicates 9 mm (6/16’’). Increasing the
penetration at this angle will distort the bevel. The maximum bevel width (b ≈21 mm,
13/16’’) is obtained for the angle of 45°. The demanded bevel width for the required
angle must be determined experimentally by gradually increasing the milling head
penetration into the workpiece.
3.1.2. Using cutting fluid
Before beveling stainless steel, cover the edges of the workpiece with the supplied oil
in the manner shown in Fig. 3.

SM-BM-21S
3.2. Operating
After setting the bevel width and angle, plug the machine into a properly grounded
power outlet. Then, place the machine vertically on the right side of the workpiece as
shown in Fig. 4 in a way that the milling head does not touch the working edge.
Fig. 4. Machine prepared for work on metal plates
Turn on the power, which will illuminate the power switch (Fig. 5). Then, turn on
the motor using the motor ON switch, press the guide to the plate, and slowly move
the machine close to the edge. Bevel by sliding the machine to the left. Beveling is
performed according to the counter-rotation. The proper feed direction is shown in
Fig. 4. The direction of the milling head rotation is indicated on the motor disk under
the milling head cover.
feed direction
SM-BM-21 Operator’s Manual

SM-BM-21S
Fig. 5. View of the control panel
The feed rate will depend on the profile and composition of the workpiece. You
can bevel the majority of steels capable of being welded in just one pass.
It is recommended that bevels wider than 12 mm (1/2’’) be accomplished in at
least two or three passes. In this case you use less effort and the process takes less
total time than for beveling in single pass.
To obtain the maximum bevel width (21 mm, 13/16’’) in two passes, the first pass
should be 14 mm wide (9/16’’), whereas for three passes the first one should be
12 mm wide (1/2’’) and the second one 16 mm wide (5/8’’).
If the feed is too fast, the red overload lamp illuminates, indicating motor overload.
Further increasing of the load will trigger the safety circuit and shut down the motor.
In this case, move the tool away from the beveled edge, toggle power switch to
position ‘0’, and after the red lamp turns off, turn on the power again. Operating with
the maximum permitted load (the red lamp flashing) is allowed, but the motor
temperature must not exceed 85°C (185°F). This type of motor can work under high
temperatures, but long-lasting overheating can permanently damage motor windings.
Therefore, after longer working under full load (up to 1 hour), stop the motor to cool it
for 10–15 minutes. Do not cool the motor by running it without load as it will become
heated even faster than when working with load.

Once the work is finished, press the motor OFF switch to stop the motor, and
toggle the power switch to position ‘0’ to turn off the power. Use petroleum ether to
clean the oil remainder from the workpiece.
Clean the machine with a cotton cloth without using any agents.
3.3. Beveling pipes
The guide with rollers supplied in standard equipment allows beveling pipes with
diameters of 150–300 mm (6–12’’).
To prepare the machine for work on pipes, use the supplied 6 mm hex wrench to
unscrew two screws locking the guide (Fig. 6). Then, take out the guide set, rotate it
by 180° around the vertical axis, mount again, and secure with the screws.
Fig. 6. Preparing the machine for work on pipes
Use the supplied 8 mm hex wrench and the 12 mm flat wrench to unscrew the
screws securing the rollers. Then, move rollers from the opening (Fig. 7a) to the slot
(Fig. 7b) by placing the T-nut into the slot.

Use the adjusting knob to set the indication ‘0’ on the width pitch. Move the
rollers away from each other and place the machine as shown in Fig. 8, with the
guide touching the pipe. Then, move the rollers symmetrically to touch the pipe,
secure with the screws in this position, and set the required bevel width and angle.

3.4. Beveling larger pipes (only for optional equipment)
An optional guide allows beveling larger pipes with diameters from 260 mm to 600 mm
(10–24’’). To prepare the machine for work on larger pipes, disassemble the guide set
as shown in Fig. 6. Use the supplied 4 mm hex wrench to unscrew the standard guide
and mount the guide for larger pipes (Fig. 9), then screw in the screws and mount the
rollers as shown in Fig. 7b.

3.5. Replacing the cutting inserts
The machine is equipped with an uniform milling head that contains two insert rings,
each holding five cutting inserts made of carbide, for a total of 10 inserts. The inserts
can be replaced or rotated. Perform this work only with the power cord unplugged
from the power outlet. To replace or rotate an insert, unscrew the lever (Fig. 10),
remove the pitch, and take out the milling head cover.

Fig. 10. Dismantling the milling head cover
Use the supplied screwdriver to unscrew the set screw (Fig. 11), then remove the
external insert, and clean the socket. Next, place the rotated insert again or replace
with a new one if all four edges are worn out. To replace an insert from the internal
ring, remove the external insert first.
Fig. 11. Replacing the cutting inserts
If the width of established bevels is low, the cutting inserts wear only on one, internal
corner. Then, the good action is to change the inserts between the rings (Fig. 12),
which will extend the life of the inserts.
