SM-BM-21S 1. GENERAL INFORMATION 1.1. Application The BM-21S is a beveling machine designed to bevel stainless steel. The machine can bevel plates, as well as pipes with outer diameters of 150–300 mm (6–12″), at an angle of 0–60° and with the bevel width of up to 21 mm (13/16″). Also, the machine contains dampers to reduce vibrations.

SM-BM-21S 21. Maintain the machine and install/remove parts and tools only after you unplug the machine from the power source. 22. Repair only in a service center appointed by the seller. 23. If the machine falls, is wet, or has any damage, stop the work and promptly send the machine to the service center for check and repair.
SM-BM-21S 3. STARTUP AND OPERATION 3.1. Preparing 3.1.1. Adjusting the bevel angle and width Unplug the machine from the power source. Start with setting the bevel width to zero. To do this, loosen the lock lever (Fig. 3), rotate the knob to set ‘0’ on the bevel width scale, and tighten the lever.
SM-BM-21S After you set the bevel angle, use the depth knob to adjust the bevel width. The width scale shows only a rough value because the bevel width varies with the angle. For example, for 10° the maximum width b (Fig. 1) is about 18 mm (11/16″), while the width scale shows about 9 mm (6/16″).
SM-BM-21S 3.2. Adapting for 150–300 mm pipes To bevel pipes with diameters of 150–300 mm (6–12″), assemble the standard guide set in a different way. To do this, use the 6 mm hex wrench to remove two side screws (1, Fig. 6) and remove the guide set (2). Remove the set by 180° around the vertical axis (3), install again (4), and attach with the screws (1).

SM-BM-21S 3.3. Adapting for 300–600 mm pipes (option) To bevel pipes with diameters of 300–600 mm (10–24″), assemble the guide set by using an optional guide. To do this, remove the guide set (1, 2, Fig. 6) and use the 4 mm hex wrench to remove the standard guide.
SM-BM-21S 3.4. Operating After you set the bevel angle and width, connect the machine to a correctly grounded power source. Put the machine on the right so that the rollers are on the plate. Keep a gap between the milling head and the plate (Fig. 11).

SM-BM-21S You can work near the overload (when the red lamp flashes), but do not let the motor temperature increase more than 85°C (185°F). This can lead to damage of the motor windings. After each hour of work under full load, stop the motor for 10–...
SM-BM-21S 3.5. Replacing the cutting inserts Unplug the machine from the power source. Remove the lever (1, Fig. 12), the indicator (2), and the milling head cover (3). Fig. 12. Removing the milling head cover Use the supplied T15P screwdriver to remove the fixing screw (Fig. 12), remove the insert, and clean the socket.
SM-BM-21S When you make bevels of low width, the cutting inserts wear only on one, inner corner. Then, the good thing is to change the inserts between the milling cutters (Fig. 7). This will extend the life of the inserts.
