Above mentioned values are valid for spruce wood at relative air humidity of 12 - 15 %
and sharp knives 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 knives 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.
With feed speed over 12.5 m/min, the torque of the electromotor is decreased due to
the over-excitation and thus the feed speed is decreased.
It is necessary to count with worsened quality of processing at planing of materials of small
thickness considering the springing of planed material piece.
With the increasing feed speed, the quality of the machined surface is lowered.

3.4 Machine nois data (EN 861:1998; ISO 7960:1995)

Above stated values are those of emissions and need not represent the safe working values.
Although there is a correlation between emissions values and levels of exposition, these va-
lues cannot be used for a reliable statement whether other precautions are necessary or not.
Agents, influencing real exposure of workers, include other working space attributes, other
sources of nois, etc., e.g. the number of machines and other from neighbourhood influencing
processes. The most permissible exposition levels can differ according to country in questi-
on, too. This information will serve for machine user to a better astimation of risks.

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 exhaus-
ting 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 space surrounding
the machine.
If a long peace is planed, it is necessary to have
a sufficient space in front of and behind the ma-
chine in places of material in- and output.

6.2 Machine levelling and fixing

In the lower part of frame, the machine is fitted


with legs with levelling screws and with openings
for anchoring screws.
Under the leveling screws, use steel washers
(they are a part of the supply) and do level the
machine in a flat plain field with a tolerance 0.5
mm / 1000 mm and do screw them to the bottom
(anchor them).
Attached drawing shows a lay-out of anchoring
openings on the machine.

ROJEK a.s. 20 RFT 630, 520, 410


7 Connecting of exhaustion
An exhausting unit of minimal volumetric capacity 1270 m3
h-1 and minimal air stream speed in the hose 20 ms-1 for dry
particals, and 1780 m3h-1 at minimal air stream speed in ho-
se 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 !

For connecting, use a flexible extraction hose with a diameter of 150 mm. Connect the ex-
traction hose to the extraction nozzle, location of which is at the machine outlet, with outfall
to the right, to the left or directly backwards.

Wooden waste must be liquidated eco-friendly - not to worsen the environment.

ROJEK a.s. 21 RFT 630, 520, 410


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 the mains

Make sure that no voltage is at the sup-


ply lead before connecting. Open the
door of the electrical cabinet, push the
connecting cable inside using a bushing
and connect individual phase conduc-
tors to the corresponding terminals lo-
cated at the bottom of the electrical
switchboard. 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 accuracy of connecting
and fasten the terminal door again.

8.2 Operation safety


A damaged supplying lead must be replaced immediately
by a competent specialist. The operation of a machine
with a damaged supply cables is dangerous to life and it
is forbidden !
Before commissioning the machine, make sure that the voltage and frequency stated at the
type label of the machine corresponds with the values of the grid, to which it is connected.
The grid supply, from which the machine is powered, must be performed according to the
regulations and secured at least by 25A safety fuses or a circuit breaker of the L type.
According to CSN 33 2000-4-482 (epv. HD 384.4.482 S1, according to Art. 482.1.7) in a dis-
tributing system other than cables with mineral insulation and busbar distributing system,
must be protected against insulation failures in TN grids using current protectors with rated
equipping difference current IΔN ≤ 300 mA (see IEC 364-5-53, Art. 531.2.4; of the corre-
sponding standard for the product).

Always switch off the machine main switch and lock it


before the tools adjusting and replace and all adjusting,
treatment and maintenance works. Herewith you avoid
eventual machine starting by chance by an else person.

ROJEK a.s. 22 RFT 630, 520, 410


8.3 Rotating direction

An injury danger menaces at an improper rotating di-


rection of the cutter block !

If you stand on the left side of the machine near the stand cover (see Chap. 9.1 pos. 11),
the cutter block must rotate counter clockwise, i.e. to the left.
In order to ascertain the rotation direction, remove the stand cover and turn on the machine
for a short moment.

ROJEK a.s. 23 RFT 630, 520, 410


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 make this change and to
realize the connecting !

Start the machine without tools for a flash to learn its rotating direction.

8.5 Protection of electric parts

The electric motor of the draw is equipped with an electric brake, able to stop the cutter block
in a required term ( 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
and IEC 60 364-4-41.

9.2 machine adjusting 9.2.1 Table Adjustment
Table position changing (by setting height) sets a parameter
(thickness) of machined part. Unevenly thick pieces should
always be inserted with the thicker end first. Unevenly wide
pieces should always be inserted with the wider end first.

9.2.1.3 Table Roller Adjustment

Table rollers are located in a specially modified table and allow for better passage of ma-
chined material through the table. They are free-running with the possibility of height setting.
Adjustment is performed using a hand grooved nut. By turning to the right, the rollers can be
set upwards and vice versa. The roller exposure size above the table plane can be chosen in
the range of 0 to 1 mm according to the nature of accuracy requirements of the machined
area and the machined material. The larger the roller exposure, the larger the breach of the
table planarity and thus the possibility of worsening the quality of the machined area.

ROJEK a.s. 31 RFT 630, 520, 410


9.2.1.4 Table Scale Adjustment

If the value read at the scale (1) does not


correspond with the actual thickness of
the workpiece, it is possible to perform a
repair by moving the indicator (2) in the
fixing grooves.

9.2.1.5 Adjusting the Table Parallelism with the Cutter Block

Always turn off the main switch and lock it or disconnect the
machine by pulling out the fork. This will exclude the possi-
bility of random starting of the machine by someone else.

If the machined part shows uneven thick-


ness across its width and if the effect of
cutter setting accuracy in the cutter block
is excluded, it is possible to adjust the
block and table parallelism in the follow-
ing manner:
- Unscrew fixing screws (A), push cover
ing case (B) down from lower part
of motion screw (C)
- release holder (D) gripping connection
by releasing the screw (E)
- Release screw (F), connecrting motion
screw (C) with table boss (G). Herewith
the whole assembly gets loose.
- Index the motion screw (C) by hexagon
wrench (hexagon gap in lower part).
Herewith the parallelity of table with
cutter block gets adjusted (changed).

WARNING: Do adjust always both screws


at the same side of the table from the
standpoint of material passing, the screws
have a right thread and pitch 6 mm, which
means that turning the screw by 6o results
in a change of 0,1 mm.

We recommend leaving this to an expert service.

ROJEK a.s. 32 RFT 630, 520, 410


RFT 520, RFT 410

If the machined workpiece gets out unevenly thick (across its width) from machine, not cau-
sed by cutters adjusting accuracy in cutter block, the cutter block with table parallelity can be
adjusted as follows:
- Thicknessing table is fast connected with pole (A). Pole moves in body (B). Cube (E) is
fixed to body (B). Cube (E) is connected with cube (D) by body (B). Cube (D) is fast connec-
ted with the stand by screws (C).
Release screws (F). Mutual position od cubes (D) and (E) can be changed by pushing off
screws (G). Hereby the parallelity of machine table with cutter block can be adjusted.

WARNING: Do adjust always both screws at the same side of the table from the standpoint
of material passing. Tighten all wel.
We recommend to let the (table║cutter block) parallelity adjusted in a special service.

tion Admeasuring Sensor

The end switches of the upper position (A) and the lower position (B) are located under the
right stand cover and are fastened using holders (C) to the stand with the possibility of hori-
zontal adjustment. The upper position stopper (D) and lower position stopper (E) are born by
a holder (G) fastened to the machine table. After releasing the locking screws, both stoppers
(D and E) can be adjusted in height and thus the upper and lower turning off position can be
adjusted. The bar of the stoppers (D and E) also bears the impulse sensor (F) that must be
adjusted to a gap of 1 to 2 mm from the magnetic tape (H).

9.2.2 Cutter Block Drive

Always turn off the main switch and lock it or disconnect the
machine by pulling out the fork. This will exclude the possi-
bility of random start of the machine by someone else.
The drive of the cutter block (A) is using V-belts (B) from the main machine electromotor (C).

Pulley adjustment into one vertical plane can be performed by sliding the motor pulley after
releasing the securing screw (E) or by sliding the electromotor holder (F) in the stand
grooves, after releasing of tensioner (D).

9.2.3 Feed Rollers


9.2.3.1 Feed Roller Drive

The torque from the motor is transferred from the motor using a chain to feed rollers and
those convert it by friction into the feed force of the machined part. The drive allows for con-
tinuous or step change of the feed speed.

9.2.3.1.1 Frequency Controlled Motor

Always turn off the main switch and lock it or disconnect the
machine by pulling out the fork. This will exclude the possi-
bility of random start of the machine by someone else.

The feed electromotor with a gearbox (A)


is located at the rear side of the machine
stand and using a chain (B) (with idler
pulley) it drives the slide rollers (C).

Adjustment of the chain wheel (D) of the


gearbox (A) into one vertical plane with
the chain wheels of the rollers is per-
formed after releasing the securing screw
by sliding along the outlet block of the
gearbox. The belting chain wheel (E) is
floating on its block and self-adjusting.

Performed by turning the housing body
(A) around the pivot using the nut (B)
and the screw (D) that is locked in the
body using the nut (C).
B) Pushing Force Adjustment
Performed by changing the leaf spring
rigidity (E) by its compression using the
screw (F) and the nut (G), the set posi-
tion is locked using the nut (H).
C) Setting of thrust
The thrust gets adjusted by stiffness
change of leaf spring (E) by pressing it
with screw (F) and nut (G). The set up
position gets locked by nut (H).

9.2.4 Pushing Edges

Before and after the cutter block (C), there is a pushing edge (A and B).

The front pushing edge is divided and


individual segments are put rotary on
the pivot and it is possible to adjust their
height position against the cutting cylin-
der and they are sprung.
The front edge is adjusted by 1 mm un-
der the cutting cylinder (cutting cylinder
= the cylinder circumscribed over the
cutter edge), that is 2 mm under the
“body” of the cutter block.
The rear edge is solid of hardened
sheet metal and it is adjusted to
0.1 through 0.5 mm under the cutting
cylinder.

ROJEK a.s. 38 RFT 630, 520, 410


9.2.4.1 Front Pushing Edge

It is located between the pulling-in roller and the cutter


block. It allows the pushing of machined piece, splinter re-
moval , and it is height adjusted according to splinter thick-
ness.

a) Height Position Adjustment


The front pushing edge (A) is pushed
into the basic position by a spring (C)
and to a value of 1 mm under the cut-
ting cylinder (B) it is adjusted using the
screw (E) with the locking nut (D).
- Due to the max. splinter of 8 mm, the
upper position of the front pushing edge
(A) is limited by a screw (G) with a lock-
ing nut (F) to a max. value of 10 mm.
b) Pushing Force Adjustment The
pushing force of the front pushing edge
(A) is not adjusted and it is given by the
rigidity of the sprig (C).
9.2.4.2 Rear Pushing Edge
Always during adjusting the height setting of the rear push-
ing edge, it is necessary to verify that the edge cannot col-
lide in the upper position with the cutter block and whether in
the lower position, the edge ramp is above the plane of the
cutting cylinder (The front edge of the machined part must
not damage the edge, but only lift it using the edge ramp).
The rear pushing edge is situated beyond the cutter block. The rear pushing edge enables
thrust of workpiece, the edge shuts the exhausted space. The rear pushing edge is made
from springy hardened metal sheet (A), that is fastened to holder (D). Holder (D) is pivoted in
blocks (G).

a) Adjustment of Parallelism with the Cutter Block


On the right side, the pivot is fitted with an eccentric, (F) by turning which after releasing the
locking screw (G) it is possible to adjust the parallelism of the edge with the cutter block.
b) Adjustment of the Height Setting
After releasing the locking screw (B), it is possible using the arm (C) to turn the transom (D)
with the pushing edge (A) around the pivots of the housing (G). Set the edge (A) so that its
lower area is in the range of 0.1 to 0.5 mm below the cutting cylinder.

(E) will push out the cutter (A) of the
cutter block (B) against the stirrup (G)
of the setting jig.
The stirrup serves as a stopper and the
cutter ejection size (A) above the sur-
face of the cutter body (B) corresponds
to a value of 0,9 mm.
Hold the setter pushed above the cutter
(A) and gradually tighten the wedge
screws (D), best gradually from the cen-
tre of the cutter towards the edges.
Repeat the procedure gradually with all
cutters.

10.3.2 Adjustment using a Dial Indicator

After releasing the screws (D) of the


wedge (C), let the cutter (A) by pushed
out with the spring (F) with a pivot (E)
above the body of the cutter block (B) to
a value of over 1 mm.
Using hard wood, a silon chock or simi-
lar material knock the cutter (A) into the
cutter body (B) and check the value of
ejection above the cutter block body
with a dial indicator (G) as shown in the
picture. The check must be performed
always at both ends and in the middle
of the cutter with all cutters in the cutter
block.
After aligning, gradually tighten the cut-
ters with wedge screws (D), best from
the cutter centre to the edges.
Repeat the procedure with all cutters
and try to adjust them
to the same value that must range with-
in 0.8 to 1 mm.

11 Maintenance and repairs
Always disconnect the machine from the mains before
any maintenance or repair ! Switch off and lock
the main switch or disconnect the machine by towing
off the plug. Herewith you avoid a possibility of an o-
ccasional starting the machine by somebody else.
The backlash-catchers must be kept in good operation condition.
The backlash-catchers must be tested once a workshift at least. The catchers´contacting
plates must not be damaged by bumps. A spontaneous tilting-by-own-weight of backlash-
catchers must be assured.

11.1 Table Setting Drive Chain Tensioning


11.1.1 Table setting by hand wheel (RFT 520, RFT 410)

When tightening the chain (A) for table adjusting it is necessary to change the axe distance
of motion screw and chain wheel axe (C) of hand wheel. After releasing the fixing nut (E), it is
possible to shift with the chain wheel axe holder (C) and herewith to tighten the chain (A).
When the chain is tightened, it is necessary to shift the digital position indicator to machine
base and to arrest it.

11.1.2 Electromotoric adjusting of table (RFT 630)

The table adjusting drive chain (A) gets tightened by help of tensioner (B).
The tensioner is anchored to machine base.

11.2 Cutter Block Drive V-Belt Tensioning

Using the nut (C) at the tensioning screw,


change the position of electromotor hold-
er tilt so that the belts (B) of the cutter
block drive (A) are sufficiently tensioned.
Secure the position again by tightening
the nuts.

If you press with your hand on a correctly


tensioned belt with a force of about 20 N
(about 2 kg), it should bend by about 10
mm.

11.3 Tensioning of feeding drive chain


11.3.1 Tensioning of feeding drive chain RFT 630

Tensioning of feeding drive chain (A) is


automatic by help of idler (B) controled
by spring (C). The spring (C) drawing
strength
is adjusted by changing the length of
anchoring chain (D). Due to chain (A)
length and idler mulfunction, it is pos-
sible to adapt the length of chain (A)
girting by changing the axis distance of
driving chain wheel: release screws (E),
electric gearbox shifts down/ or upward.
Fix the new position - tighten screws
(E) again.

11.3.2 Tensioning of feeding drive chain RFT 520, RFT 410

Tensioning of feeding drive chain (A) is


automatic by help of idler (B) controled
by spring (C). The spring (C) drawing
strength
is adjusted by changing the length of
anchoring chain(D). If, due to chain (A)
length is the idler dud, it can be ne-
cessary to shorten the chain (A) with a
binding member.

11.4 Setting the mechanic digital indication of thicknessing table position

(At the display (B) depicted) mechanical


digital course indicator (A) value, [after
releasing screw (C),] can be changed
by turning the ring (D). When the new
value is set, it is necessary to tighten
the screw (C), and to take care so as
the reaction catching pin [in place (E)]
(course indicator fixing against turning)
would be pushed into machine stand
positioning opening.

11.5 Setting thrust of pulling in and pulling out rolls

Adjusting is described in chapter 9.2.3.2 Adjusting of feeding rolls.

11.6 Cleaning and lubricating

Clean the machine regularly. Oil bars, gudgeons, screw bars and other parts amenable fret.
The oiling frequency depends on the way of working, but apply it minimally once a month.
Bearings of electric motors and shafts have a permanent grease filling and are sealed
(closed). For this reason - do not grease them.
Clean the tables from resin by suitable solvent - for example by turpentine or petroleum,
or by other suitable solvent according to your needs.
Take care so as the belts are not fouled (dirty) with oil or grease. In case it happens, clean
the belts only with paper.
Clean the machine from dust with a vacuum cleaner. It should be done 1 x a week at least.

vings exhausting gets jammed - it is necessary to switch off the machine before carrying out
the remedy. Stop the machine immediately if it gets jammed with the workpiece !
Blunt tool - cutter block knife/-ves is often a cause of electric motor overheating. If the machi-
ne excessively vibrates - check up its levelling and attachment, respectively fixing and
ballancing of knives used in cutter block.

Machine does not work:


It is necessary to check up electric installation and connecting to the mains.

Thicknessing table moves hard:


It is necessary to lubricate the movement screws of the table height setting.

Machine output is insufficient:


Tools are not sharp.

A too thick splinter is chosen – it is necessary to consider the width and hard-
ness of the wood.
Polluted table.
The V-belts of the cutter cylinder are not sufficeintly tensioned.
Electric motor does not perform full output. - A specialist should solve it.

Machine vibrates :
Poorly sharpened or adjusted cutters.
The cutters have an uneven width, height.
The machine is not level, it is not levelled well .

Thicknessing is not possible on the machine:


Too large splinter.
The thicknessing table is not clean.
