The value given above apply for spruce wood of a common quality with humidity equal to
about 12 to 15%, with sharp tools These values may be thought initial while the machine is
being put into operation. The inverse proportion applies between the machined surface (ma-
chined width x chips removed) and the feed (the larger the surface the smaller the feed) and
the direct proportion applies between the machined surface and the power output (the larger
the surface the higher power output). The values in the table may roughly be used for both
planing and thicknessing as well as for milling with a vertical spindle. After a long use of the
machine these values may become changed a little. E.g. when hard wood is machined and
the tool is a bit blunt, an appropriate decrease of the values above should be taken into ac-
count.
The size of chips removed depending on the machined width and hardness of the workpiece
may be chosen only up to such values with which the driving electric motor does not become
overloaded. Otherwise the electric motor thermal protection will be engaged and the ma-
chine will stop.
While any material with a low thickness is being machined, a worse quality of machining
must be taken into account due to the part springing.

The values given are those of emissions and do not necessarily mean any safe working val-
ues. Although there is a correlation between the value of emissions and the levels of expo-
sure, these values cannot be used for reliable determination whether or not additional
measures are necessary. The factors influencing actual levels of workers‘ exposure include
the properties of the working area, other sources of noise etc., e.g. the number of machines
and the other neighbouring procedures. Also the highest permissible levels of exposure may
vary in different countries. This information should help the machine user to evaluate the risk
and the risk rate in a better manner.

5. Transport and storage
5.1 Transport and storage
While transporting or handling the machine, be most careful and let this activity be done by
qualified personnel especially trained for this kind of activity.
While a machine is being loaded or unloaded,make sure
that no person or subject gets pressed by the machine !
Do not enter the area under the machine lifted
by a crane or a high-lift truck !
During transport or storage the machine must be protected
against excessive impacts and humidity.
It should be stored in a shelter at temperatures ranging from -25°C to 55°C.
As standard, the machine is wrapped up in a foil and is transported this way. Upon request
the machine may also be packed in a wooden box.
5.2 Machine lifting
The machine or its individual parts may only be lifted by
means of an approved lifting device with verified lifting ca-
pacity. It is recommended to use: D - high-lift truck E -
crane or any other lifting device F - manual lifting carriage
Use a high lift with forks of a sufficient length !
Prepare a high-lift truck (D) or a
manual lifting trolley (F) with suffi-
cient lifting capacity
- put the forks (G) below the ma-
chine.
Should you use a crane (E) or a
similar hoisting equipment, proceed
as follows:
- prepare four lifting ropes (H) of
sufficient lifting capacity or steel
ropes joint circles at least 4 m long
- fix the ropes to the hook of the
crane with the required capacity
- place the other end of the ropes on
the lifting rods according to figure
(rods are not part of delivery)
- use rope underlays and spreaders
not to damage the machine
- after lifting the machine slightly
check the stability of the machine
hanging on the ropes, eventually
change underlays and spreaders
placing under ropes
- lift the machine carefully and slowly
and then move it without rapid mov-
ing to chosen place.

6. Positioning the machine
Remove the protective coating from the working tables and other parts of the machine either
with paraffin oil or any similar solvent, do not use petrol or similar solvents for this acti-vity –
they might cause reduced corrosion resistance of certain parts of the machine.
The working area size depends on the type of the machine, assumed working operations
and size of material machined.
Do not forget about the space for location of a sufficiently effective exhausting system or
connecting hoses for the central exhaustion.
6.1 Working area
It is important to maintain free area
of 0.8 m around the machine, which is
required for the working place.
If any long material is machined, it is
necessary to have a sufficient room in
front of the machine as well behind it in
the places of material input and output.
6.2 Levelling and fixing the machine
In the lower part of the stand the machine
is equipped with legs with levelling bolts
and holes for anchoring bolts. Use steel
washers under the levelling bolts (includ-
ed in the delivery) and level the machine
horizontally with tolerance of 1mm/1000
mm and screw into the floor (anchor).
The attached drawing shows the location
of the anchoring holes on the machine.

8. Connecting to the mains
The first connection of the machine to the mains may
only be realized by an electrotechnically qualified per-
son, knowing standard norms.
8.1 Connecting to the mains
8.1.1 Connecting the machine - up to 3 kW
(installed power output up to 3 kW inclusive)
For the power supply a four-wire cable with plug CEE 16 amperes and socket CEE 16 am-
peres is used. The socket from which the machine is supplied with power must be grounded
(or connected to the neutral wire) in compliance with regulations, protected by at least 16 A
cut-out fuse or circuit breaker L.
8.1.2 Connecting the machine - above 3 kW
(installed power output above 3 kW)
Before you start to connect the machine, make sure that the lead is not under voltage.
Unscrew the cover of terminal board (A), push the connecting cable through to the box with
the terminal board and connect individual phase conductors with the corresponding termi-
nals. Connect the protective conductor (yellow-green) to PE terminal and connect the central
conductor (light blue) to terminal A, if it is required. Cross-sections of the phase conductors
and of the protective wire must be in compliance with the standards prescribed.
Check that the connection is correct and screw the terminal board cover back.
