Above mentioned values are valid for spruce wood at relative air humidity of 12 - 15 %
and sharp cutters in cutterblock. These values can be regarded as starting ones at taking
the machine to operation. At longer machine use these values can be partly changed. E. g.
at planing of harder woods and at cutters getting blunt it is necessary to count with adequate
reduction of stated values.
Shavings removal thickness related to planed width and hardness of wood can be chosen
only within the values at those driving motor does not get overloaded. On the contrary
the protection of motor will act and the machine will get stopped.
It is necessary to count with worsened quality of processing at planing of materials
of small thickness considering the springing of planed material piece.

ROJEK a.s. 15 RFS 410, 510
6 Positioning of machine
Remove protecting coat from table and other machine parts with a solvent. Do not use petrol
or kindred solvents for this action. They can cut down resistance against corrosion of some
machine parts.
The working space extent depends on machine dimensions, intended working operations
and dimensions of processed material.
Do not forget to let free a big enough space for installment of a sufficiently effective ex-
hausting unit or hoses connecting with the central exhausting system.
6.1 Working space
It is important to keep a free space of at
least 0,8 m, requested as working spa-
ce surrounding the machine.
If a long peace is planed, it is necessary
to have a sufficient space in front of and
behind the machine in places of mate-
rial in- and output.
6.2 Machine levelling and fixing
The machine is equipped with feet, (in lower frame part).
When the bottom is not flat, level the machine by help of fillers in allowance 1 mm/ 1000 mm
and screw feet to the bottom (anchor the machine).
Attached drawing shows a lay-out of anchoring openings on the machine.
RFS 410 - A x B = 930 x 374 mm
RFS 510 - A x B = 1030 x 474 mm

for wet particals, is necessary for 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 150 mm for connecting. Connect the exhausting
hose to nozzle, placed in rear part of the machine.
Wooden waste must be liquidated eco-friendly - not to worsen the environment.

ROJEK a.s. 17 RFS 410, 510
8 Connecting to the mains
Only a qualified person is allowed to realize the first
connection of the machine to the mains.
8.1 Connecting 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 terminal board
and connect individual phase conductors with corresponding clamps. Connect the protective
conductor (yellow-green) to the clamp PE and the central conductor (pale blue) to the clamp
N, if it is required. Cross- sections of phase conductors and of the protective conductor must
be conformable with legal standard norms. Check up the rightness of connecting and fasten
the terminal cover with screws again.
8.2 Operation safety
Damaged supplying lead must be replaced immediately
by a competent specialist. Machine run with damaged
supply cables is dangerous to life and forbidden !
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 network.
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
eventual machine starting by chance by an else per-
son.

ROJEK a.s. 18 RFS 410, 510
8.3 Rotating direction
An injury danger menaces at improper rotating direction
of cutterblock !
When standing at the input table side of planer against guiding ruler – the cutterblock must
rotate against incoming material, i. e. to the right in direction of arrow situated at cutterblock.
Start the machine for a flash to learn the spindle rotating direction.
8.4 Rotating direction change
It is possible to change rotating direction of 3-phases motors by exchanging (switch-over) of
conductors one instead of another (between 2 black ones or a brown and a black one) on
supplying plug. Attention ! Avoid of mistaken changing of yellow-green wire with the phase !
Entirely a specialist qualified in electrotechnics is allowed to change the conductors -
to reconnect the motor for rotating direction change !
Start the machine without tools for a flash to learn its rotating direction.
8.5 Protection of electric parts
The electric motor of the planer is equipped with an electric brake, able to stop the spindle in
required time ( within 10 s).
If the electric brake does not work well (spindle run out is more than 10 s) it is forbid-
den to work on the machine !
The protection against dangerous contact of inanimate parts is assured with a self
acting disconnecting from the mains according to the norm EN 60 204-1 ed.2
and IEC 60 364-4-41.

ROJEK a.s. 19 RFS 410, 510
8.6 Machine control
8.6.1 Operating machinery from panel on stand machinery (lower operating)
8.6.1.1 Machine connecting
The connecting and disconnecting of
machine is done by switching ON and
OFF of the lockable main switch (A).
Till the machine is disconnected, it
cannot be started.The main switch can
be secured with a pad lock against an
ineligible machine starting.
8.6.1.2 Machine starting - stopping
The machine motor gets started by
pushing the green knob (B) at the star-
ter of the main control panel.
The motor gets stopped by pushing
the red controler (C). In case of a ma-
ins failure the machine is switched off
by a tapped coil, it 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 braker
switches it off several times in a
sequence.
8.6.1.3 Controller of emergency stopping
The controler of emergency stopping (H), after having been used, will remain locked in the
position OFF, and before a new machine starting it is necessary to release it by indexing of
the „mashroom“ head. The machine cannot be started without this releasing.
8.6.1.4 Main switch and electric motor brake release
For an easier manipulating with cutterblock when exchanging the cutters it is possible to
equip the machine with an overswitch (G) for motor brake releasing.
Position 1- normal run
position 0- OFF
position 2- released; after overswitching to this position, and pushing the green pusher of
motor starter - the cutterblock will get released
position 3- cutterblock reversation (so far as the machine is equipped with reversation)
So far as the overswitch gets overswitched across the "0" position - the machine must be
always started by a motor starter.
