7.0 Exhausting connection
An exhausting unit of a minimum volumetric capacity 570 m3h-1 and a minimum air stream
speed in the hose 20 ms-1 for dry particals, and 790 m3h-1, at a minimal air stream speed in the
hose of 28 ms-1 for wet particals, is necessary for a proper functioning of the machine.
Always operate machine only with running
exhausting !
Start the machine and the exhausting unit all at once
!
Use a flexible exhausting hose of diameter 100 mm for connecting to the lower exhaustion
outlet branch.For the upper exhausting outlet branch in accordance with the machine made:
- Use a hose of Ø 40 mm (only for PF 300L; PF 300LE)
- Use a hose of Ø 60 mm for the saw blades guard on the arm R.
- Use a hose of Ø 100 mm for the saw blades guard on the arm CPS.

The wooden waste must be liqudated eco-friendly - not to worsen the
environment.
8.0 Connecting to mains
Only an electrotechnically qualified person, cognizant
of rated norms, can connect the machine to the
mains.
8.1 Connection to mains
Make sure that no voltage is at
the supply lead before connecting.
Unscrew the cover of the terminal
board (A), put the connecting cable
through - into the box with the termi-
nal board and connect individual
phase conductors with correspond-
ing clamps. Connect the protective
conductor (yellow-green) to the
clamp PE and the central conductor
(pale blue) to the clamp N, if requi-
red. Cross-sections of phase con-
ductors and of the protective con-
ductor must be conformable with
legal standard norms. Check up ac-
curacy of connecting and fasten the
terminal cover with screws again.

8.2 Safety of operation
Damaged supplying lead must be replaced
immediately by a competent specialist. Machine run
with damaged supply cables is dangerous to life and
therefore forbid-den.
Before establishing the machine to the run make sure that the voltage and frequency stated
on the machine rating plate answer to those of supplying mains.
Always switch off the main switch and lock it or
discon-nect the machine by towing the plug from the
socket before tools adjusting and replace and all
adjusting, treatment and maintenance works.
Herewith you avoid
an unfought starting of machine by an else person.
8.3 Rotating direction
An injury danger menaces at an improper rotating
direc-tion of cutterblock !
When standing at the place of machine
operator - the main saw blade must
rotate clockwise (= to the right), and
the scoring saw blade, if installed, must
rotate anti-clockwise (= to the left).
8.4 Changing of saw blade rotating
direction
It is possible to change rotating direc-
tion of 3-phases motors by exchang-
ing (switch-over) of conductors one
instead of another (between 2 black
ones or a brown and a black one) on
supplying plug or at terminal board.
Attention ! Avoid of mistaken changing
the yellow-green wire with the phase !
Entirely a specialist qualified in
electrotechnics is allowed to make this change and to realize the connecting !

Start the machine for a flash so as to learn its rotating
direction, if possible without tool.
An injury danger menaces at an incorrect rotating
direc-tion of saw blade.
8.5 Protection of electric parts
The electric motor of the saw is equipped with an electric brake, able to stop the spindle in a
required time ( within 10 s).
If the electric brake does not work well (the spindle run out is more than 10 s) it is
forbidden to work on the machine !
The protection against a dangerous contact of inanimate parts is assured with a
self acting disconnecting from the mains according to the norm EN 60 204-1
and IEC 60 364-4-41.
8.6 Machine control
8.6.1 Lower machine control (PF 300L; PF 350)
connecting of the machine to and
disconnecting from the mains :
The machine gets connected or disco-
nnected from the mains by switching
on/off the lockable main switch A.
The machine cannot be started before
being connected. The main switch can
be locked with a pad lock against an
unfought starting of the machine.
The saw motor gets started by push-
ing the green knob Bat the trigger
switch of the main control pannel.
The scorer motor gets started by
a handler D.
Until the saw motor is out of run - the scorer motor cannot be started.
Stopping the machine : The machine gets stopped by pushing the red controller Cat the
trigger switch of machine main control pannel.
In case of a mains failure the machine is switched off by a tapped coil, means that after the
voltage restoring the machine must be switched on again.
The inbuilt breaker will switch off the machine in case of motor overloading. Check up the
machine (motor function, blunt tools and the like) if the breaker switches it off several times in
a sequence.
Emergency stopping controller : The emergency switch Ewill stay secured in the
position OFF after being used and it is necessary to release it by turning of the “mushroom“
head. Without this releasing the machine cannot be started again.
Rotation speed choice : At a machine with a 2-speeds electric motor - the saw blade
rotating speed is chosen by the overswitch F.
Adjusting of sawing height
Sawing height gets adjusted upward by pusher Hand downward by pusher Ialways during
its being hold pushed. Both limit values of setting are secured by limit switches.
