START UP AND OPERATION
START UP AND OPERATION
WARNING! Read safety precautions
before you start to work with the machine.
3.1. Preparing for operation
Before performing any work, set required bevel width and angle (see “Adjusting bevel width and angle”
pg 9).
After setting proper values, plug the machine into an earthed power socket. Place machine
vertically on the right edge of workpiece in a way that milling head does not touch working edge. Then,
turn on the power by pressing main switch located on the motor housing (Figure 2, Item 1) to “I” position,
what will be indicated by amber light. The green button marked “I” (Figure 2, Item 2) is used to start the
machine, pressing red button marked “0” (Figure 2, Item 3) stops the machine. To turn off the power,
press main switch back to “0” position. The yellow lamp (Figure 2, Item 4) indicates operation of the tool.
Pressing vertical guide to the working edge, slowly slide machine until the tool starts to cut steel.
Bevelling is performed according to counter-rotation. The proper feed direction is shown in Figure 2;
direction of milling head rotation is indicated on the motor disc under milling head cover.

3.2. Adjusting bevel width and angle
The machine enables easy and quick adjustment of bevel parameters. Before performing adjustments, ensure that the power cord is unplugged from power socket. Adjustment of the bevel angle starts
with milling head penetration set to zero (indication “0” on the milling head cover side wall).
To change bevel angle, use size 6 Allen key and loosen two M8 bolts (Figure 3, Item 1) that lock machine guide. Then, turn the guide, setting required angle on the scale located on milling head cover side
wall (Figure 3, Item 3) and secure the bolts afterwards.
To adjust bevel width, change penetration of the milling head: loosen M8 lever (Figure 3, Item 2) and
turn adjusting knob (Figure 3, Item 5) to obtain required width.
The pitch that indicates milling head penetration (Figure 3, Item 4) is only an estimate, because
bevel width varies with angle. For example, for the angle of 10° the maximum width “b” (Figure 1) is
approximately equal 18 mm (11/16’’), while the scale indicates 9 mm (6/16’’). Increasing penetration at
this angle will distort the bevel. You can obtain maximum bevel width (b 21 mm, 13/16’’) for the angle
of 45°. Experimentally determine the required bevel width for individual angles, by gradually increasing
milling head penetration into the working piece.

3.3. Bevelling metal plates
Slide the bevelling machine to the left. Note that the feed rate depends on the profile and
composition of the working material. You can bevel the majority of weldable steels in just one pass.
It is recommended to perform bevels wider than 12 mm (1/2’’) in at least two or three passes.
To obtain maximum bevel width (21 mm, 13/16’’) in two passes, 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
should be 16 mm wide (5/8’’).
If the feed is too fast, a red signal lamp illuminates, indicating motor overload (Figure 2, Item 5).
Further load increasing triggers safety circuit and shuts down the motor. In this case, move the tool away
from bevelled edge, press main switch to “0” position and after red signal lamp turns off press main
switch back to “I” position. Operation with the maximum permitted load (with flashing red signal lamp) is
technically possible, but motor temperature should not exceed 85°C (185°F). The motor can work under
high temperatures, but long overheating may permanently damage the windings. Therefore, after every
hour of working under full load, stop the motor to cool it down for 10–15 minutes. Do not cool the motor
down by leaving it in the idle state, because it will become heated even faster than when working with
load.
3.4. Bevelling pipes
The guide with rollers supplied as a part of standard equipment enables to bevel pipes with
diameters 150–300 mm (6–12’’).
To prepare the machine for work on pipes, unscrew two M8 bolts (Figure 4a, Item 2) using size 6
Allen key. Then, take out the guide set (Figure 4a, Item 1, 5), rotate it by 180º around the axis indicated
in Figure 4a, mount as shown in Figure 4b and secure again with M8 bolts. Using size 8 Allen key and
size 12 flat key, unscrew bolts (Figure 4a, Item 4) that secure the rollers. Then, move rollers (Figure 4a,
4b, Item 3) from opening (Figure 4a) to slot (Figure 4b), placing T-nut (Figure 4a, 4b, Item 6) into the
slot.
Using adjusting knob (Figure 3, Item 5), set “0” position on the pitch (Figure 3, Item 4).
Move rollers away from each other and place the machine as shown in Figure 5, with horizontal guide
(Figure 4b, Item 5) touching the pipe. Then, move rollers (Figure 4a, 4b, Item 3) symmetrically to touch
the pipe and secure with bolts (Figure 4b, Item 4) in this position. Adjust required bevel width and angle
(see “Adjusting bevel width and angle”) and start to work with bevelling machine.

3.6. Replacing cutting inserts
BM-21 Bevelling Machine is equipped with uniform milling head (Figure 8, Item 1), containing
two insert rings, each holding five cutting inserts, for a total of 10 inserts. The inserts can be replaced
or rotated. Perform this work only with power cord unplugged from power socket. To replace or
rotate the insert, unscrew lever (Figure 7, Item 1), remove pitch (Figure 7, Item 2) and remove milling
head cover (Figure 7, Item 3).
