3. STARTUP AND OPERATION
3.1. Assembling
The carriage set on the guide in the leftmost position must be placed on the plate
between twoclamps inthe manner shown in Fig. 3a. If needed, extend the guide length
by connecting additional guide segments, and tighten the set screws using the 4 mm
hex wrench (Fig. 3b). Then, install the protective screws 1and 2at the both ends of
the guide, and position the guide using track clamps in such a way to align the track
clamps with respective surfaces of the guide and plate. Fix the track clamps using
levers (3, 4, 5), and tighten the clamp screws by rotating the clamping rods (6,7). To
adjust the pressing force of the track clamps depending on the plate thickness, use
the adjusting screws 8which can be located in one of three track clamp holes.

If the plate is to be machined at a negative angle (from the bottom), loosen two
milling unit support screws using the 4 mm hex wrench and set the indicator to the
value of the plate thickness (9). Position the milling unit support on the screws (10),
in the shown order place the washers under the nuts (11), and tighten the nuts using
the 13 mm flat wrench.
Set the lever 1in the position as in Fig. 4, insert the milling unit horizontally into
the support (2), and lock the bevel depth lock lever (3). If the plate is to be machined
at a positive angle (from the top), set the chip container on the brackets (4).

3.2. Setting the bevel parameters
Loosen the lever 1(Fig. 5), rotate the lever 2to set a proper milling head penetration
in the workpiece indicated on the scale 3(one graduation equals 1 mm, 0.04’’), and
then lock the position using the lever 1.
Fig. 5. View of the milling unit
Next, loosen the levers 4and 5, rotate the milling unit in such a way to set
a proper bevel angle on the scale 6, and then lock the levers 4and 5.
Start beveling with the milling head retracted as far as possible, especially when
milling at the angle of 0°.
Proceed with caution if the milling unit is inclined at ahigh negative angle. In such
a case when readjusting the milling head penetration near the maximal retraction,
hold the handles tightly not to allow the milling unit to slip down from the support after
the bevel depth lock lever 1is unlocked.

3.3. Operating
Plug the milling unit power cord into the socket 1(Fig. 6), and connect the cord 2to
the power source. Then, set the power switch 3to the position ‘I’ and use the knob 4
to change the travel speed of the carriage to the least possible value. Select “right”
direction of the travel using the switch 5, and start the motor with the button 6.
Fig. 6. View of the control panel
After the travel is started, set aspeed that will ensure sufficient milling performance
and prevent the overload of the motor and excessive wear of the cutting inserts. Good
effects are achieved with a speed at which the overload lamp 7will not flash.
The plate must be at all times pressed by two track clamps positioned as close to
the current position of the carriage as possible. When the carriage approaches the
track clamp, relocate the track clamp to the other side of the carriage.
Establish bevels in several passes and not exceed 4 mm (0.16’’) of the milling
head penetration d(Fig. 1) in a single pass. When the carriage reaches the plate
end, either toggle the switch 5to the opposite travel direction or first stop the carriage
with the button 8and then readjust the bevel depth or angle.
In an emergency, use the emergency switch 9to shut off the power. To restart
the operation in such a case, remove the cause of the shutdown, unlock the
emergency switch, and start the machine using the button 6.
If the speed is too high for the bevel width and depth that are set, the machine will
stop and start cyclically. In such a case, decrease the travel speed or milling head
penetration in the workpiece.

If the machine becomes overloaded, for instance when the bevel width is too
large for the material being machined, when the cutting inserts are dull, or when the
travel speed and bevel depth are too high, the spindle will stop automatically. In such
acase, hold the button 6, which will start the travel in the opposite direction and
enable the operator to retract the milling head from the workpiece. Next, release the
button 6,press the button 8,and then remove the cause of the shutdown and restart
the motor using the button 6.
If the carriage stops as a result of reaching one of the protective screws, set the
switch 5to the opposite travel direction before restarting.
Operating near the overload (with the overload lamp flashing) is allowed; however,
never allow the motor temperature to exceed 85°C (185°F) because this can lead to
damage of the motor windings. After every hour of operating under full load, stop the
motor for 10–15 minutes. Never cool the motor by running without load because it will
become heated even faster than when working with load.
After the work is finished, stop the motor using the button 8, set the power switch
to the position ‘O’, and then unplug the power cord from the power source.
Clean the machine with a cotton cloth without using any agents.

3.6. Using optional milling unit supports
To install a milling unit support, unplug the power cord, unplug the cable connecting
the milling unit to the carriage, and remove the milling unit as shown in Fig. 7.
Then, unscrew the nuts using the 13 mm flat wrench (1, Fig. 10), and remove the
installed support (2). Before installing the support for beveling 36–70 mm thick plates
at the angle of 0° to –60°, loosen two screws (3) using the 4 mm hex wrench and set
the indicator to the thickness of the plate to be machined. Position the milling unit
support on the screws (4), in the shown order place the washers under the nuts (1),
and tighten the nuts afterward.

To install the support for J-beveling, loosen the screw 5using the 8 mm hex
wrench and loosen two lock levers 6, set the body to a proper height indicated by the
scale 7, and tighten the screw and levers. Then, install the milling head for J-beveling
in the manner shown in Fig. 9.
Install the milling unit in the manner shown in Fig. 4.
To face the plate using the support for beveling 36–70 mm plates at the angle of
0° to +60°, perform the first pass with the milling unit in the lowest position (8,
Fig. 10), and then the second pass at the indication of ‘0’ (9).
Before J-beveling, prepare the plate as shown in Fig. 11 using the standard milling
head. Then, replace the milling head to a special R6 or R8 milling head for J-beveling.
During J-beveling, the carriage must travel to the left, which will reduce vibrations,
increase the life of the cutting inserts, and improve the quality of the surface. When
performing multiple passes, before every next pass, place the carriage again on the
right side of the plate, and increase the penetration of the milling head in the workpiece.
Establishing J-bevels may require several stages (Fig. 11) depending on the plate
thickness. After completing every stage, lower the milling unit, secure the support in
this new position, and perform the next stage. Proceed as described until the J-bevel is
established.
