2. SAFETY PRECAUTIONS
1. Before use, read this Operator’s Manual and complete a training in occupational
health and safety.
2. Use only in applications specified in this Operator’s Manual.
3. Make sure that the machine has all parts and they are genuine and not damaged.
4. Make sure that the specifications of the power source are the same as those
specified on the rating plate.
5. Do not carry the machine by the power cord and do not pull the power cord. This
may cause damage and electric shock.
6. Keep untrained persons away from the machine.
7. Before each use, ensure the correct condition of the machine, power source, power
cord, plug, control parts, and tools.
8. Before each use, make sure that no part is cracked or loose. Make sure to maintain
correct conditions that may influence the operation of the machine.
9. Keep the machine dry. Do not expose the machine to rain, snow, or frost.
10. Keep the work area well-lit, clean, and free of obstacles.
11. Do not use in explosive environments or near flammable materials.

4.4. Horizontal guide guards
During operation with beveling angles of 30° and 45° it is required to use the horizontal
guide guards dedicated for those angles. To replace the guard proceed as below.
Remove the hexagon socket head screws (1). Remove the basic guard (2). Install
guard (3) or (4) according to the machining angle. Tighten the hexagon socket head
screws.
The guard should touch the guide so the chips are not ejected onto the workpiece
surface.

Prepare screws (1) covered with delivered grease. Put the insert (2) in the socket,
press it down and fix with screw, using T15 torx screwdriver. Make sure that the whole
bottom of the insert touches the socket.
At the end reinstall the guards and set the guides at appropriate angle.
4.8. Replacing the cutting inserts
When inserts become dull, they should be rotated or replaced.
Unplug the power cord. Set the guides and head like during installation of new inserts.
Use T15 torx screwdriver to remove the cutting inserts. Clean the sockets.
To change the cutting edge rotate the inserts by 180°. Press the inserts towards the
sockets and tighten them. If all cutting edges are worn, replace the inserts with new
ones. Make sure that the whole bottom of the insert touches the socket.

4.10. Positioning the horizontal guide rollers
When width of the workpiece is below 110 mm, the rollers on the horizontal guide may
be set in position suitable for that width.
Remove four hexagon socket head screws (1) of the roller to be moved. Move the roller
(2) to desired position. Fix the roller with use of hexagon socket head screws.
4.11. Preparation for machining
Set the required bevel width. Then use the speed knob to set the rotational speed.

4.12. Operating
For the best results and optimum work, height of the workpiece above the surface on
which the operator stands should be approx. 70 cm, however, it depends on the
operator’s height. It allows the operator to work with slightly bent arms for lower
tiredness and better pressing force.
It is good to place the anti-slip mats on the floor in order to eliminate skid of operator’s
feet during stronger pressing. It is also favorable to use the perforated base to avoid
operator’s feet sliding on the chips.
