3.5. Operating

Connect the machine to the power source and place the machine on the left side of
the workpiece in the manner shown in Fig. 7. The milling head must not be in contact
with the workpiece. The workpiece must be balanced and well fixed.

To start the motor, press and hold the switch lock and the ON/OFF switch, and
then release the lock. Wait a few seconds until the machine reaches the required
rotational speed, press the machine to the workpiece using both hands, and slowly
slide toward the edge until the tool starts cutting into the metal. Operate according to
the counter-rotation, by sliding the machine from left to right.
the milling head is indicated by the arrow on the guide.
Begin with making small bevels (3–4 mm, 0.12–0.16'') and increase the bevel
width with gaining experience. Bevel in at least two or three passes. The bevel width
should be set to a value that will allow the feed of one meter per minute without
significant effort.
If the machine becomes overloaded, for instance when the bevel width is too
large for the material being machined or when the cutting inserts are dull, the motor
will automatically stop. However, prevent the motor from overloading by machining
hard materials in multiple passes and replacing the inserts before they become dull.
Additionally, take periodic breaks during operation, and keep the air vents unclogged
to prevent the motor from overheating as this may lead to damage of the windings.
After the work is finished, turn off the motor by releasing the ON/OFF switch, wait
until the rotation stops, and unplug the machine from the power source.
Clean the machine with a cotton cloth without using any agents.
