To start up the motor push set the ‘Star-Delta’ switch in the ‘Star’ position and push
the button S1, after about 8 sec. turn the switch to the ‘Delta’ position. Fot the
optional ‘Auto-Star-Delta’ push the start button (S1), the motor starts-up
automatically in Star-Delta. By pushing the stop button (AU1) the main motor is
automatically stopped, and slowed down by the automatic brake within 10 seconds.
The feeding motor can be started by pushing the button (POT) of the potentiometer,
and by turning the same button the feeding speed can be chosen from 5 to 22 meters
per minute.
To stop the feeding motor, push the same button (POT).
All motors are stopped automatically when the emergency stop button (AU1) is used;
Make sure the brake release switch (S4.1 ) is set at position O and the warning light
inside the same button is not lit, in order to be able to start up the machine.
When this same switch is pushed during the run of the machine the motors will
automatically be stopped.
WARNING:
All fuses can be found inside the electrical cabinet, and each time this cabinet is
opened the machine must be disconnected from the main power supply.

Dust extraction
For your own health and to avoid fire risk and dust explosion, it is recommended to
connect the machine to a dust extraction system.
The 160 mm outlet on the dust chute need to be connected to a dust extractor,
powerfull enough to obtain an airflow of at least 20 m/sec., measured at the outlet on
the machine
Changing and setting of the planer knives (fig. 4)
In order to turn the planer arbor by hand, push the brake release switch (fig.3, S4.1)
the warning light L1 will light.
Now the dust-safety hood can be opened by pulling the handle situated at the side of
the hood.
To avoid serious injuries when handling planer knives, the wear of safety gloves
is highly recommended: even blunt knives can cause serious damage to your
hands !.
Make sure both planer knives and jib strips are well cleaned before putting them into
the slots in the planer arbor.
Take care of the springs underneath the knives, and see to it that they do not stay
blocked inside their seats in the arbor.
Now put the cleaned planer knive into the groove, pushing the knive down with the
adjustment gauge(fig.4)), and tighten the bolts.
Repeat above for the other planer knives.
Make sure all knives are set at exactly the same height.
Before starting up the machine check again if all bolts are well tightened, and then
push the brake release switch (fig.3,S4.1) the warning light L1 must dim.

Safety measures on the thicknesser
- Check iff the planer knifes are well tighened and secured. When this is not the case
the knifes by the centrifugal force will be ejected from the cutter block.
It is absolutely essential to read this manual before using the machine so you
know how to the machine works and what its limitations are.
- Always make sure that all safety devices are fitted to the machine and that the
machine is connected to a dust extraction system.
- Always wear suitable clothing, loose or torn clothes are very dangerous.
- Keep children away from the machine and out of the workshop.
-To avoid damaging your hearing we recommend to wear ear protection, when
working with the machine.
- The height of a planer knife must be 20 mm minimum!
Adjusting the depth of cut on the thicknesser (fig. 5)
The raise and fall of the thicknesser table is motor driven at 2 speeds up-and down by
pushing the switch S5 for the rise and fall at fast speed, the button S7 for the slow
speed rise and fall.
The position of the thicknesser table can be set at 1/10 mm
fig.5

13

Calibration of the digital read out (fig. 6)
It is highly recommended that each time the planer knives are changed, the digital
read out is calibrated, this to avoid measurement errors.
Calibration is done as follows:
- set the thicknesser table at a random height and thickness a sample.
- now measure exactly the thickness of the sample.
- now the digital read out has to be set at the same measure, and this can be
achieved as follows: press simultaneously the buttons F and SET on the read-out:
Now the read-out begins to count up at 3 progressive speed rates:
- Rate 1: at 1Hz for 10 sec.
- Rate 2: at 10 Hz for 10 sec.
- Rate 3: at 1000 Hz for as long as the 2 buttons F and SET are held.
- Shortly before the desired value is reached, release the two buttons and press the
same two buttons so as to approach the desired value with the slowest rateof 1 Hz.
The thicknessser now is calibrated over the full 300 mm capacity.
To set the read-out at 0, simultaneously press Set and RESET.
fig.6
Important
Before starting to work on the thicknesser always ensure that the anti-kickback
protection fingers are clean and hang down freely in position under their own weight.
These anti-kickback fingers should be inspected on a regular base, and kept clean and
free of any resin deposits whatsoever.
Ensure the correct position and locking of the dust chute.
Roller supports should be used when long workpieces are machined.
Ensure the ticknesser table is well cleaned, since a smooth table surface is essential
for good operation of the thicknesser.
and RESET.

Thicknesser feed (fig. 7)
The machine is equipped with an frequency variator thus enabling an feeding speed
of 5 to 22 m/min.
The feeding motor is started-up by pushing the button of the potentiometer POT, and
by turning the same button a feeding speed can be selected between 5 and 22 meter
per minute, changing over from one speed to an other can be done without having to
stop the feeding motor.
In case of overloading of the feeding mechanism the feeding motor must be
disengaged immediately by pushing the button of the potentiometer POT and the
main cutterblock motor by pushing the emergency stop button (fig. 3, AU1) on the
switch panel.
After reducing the depth of cut on the thicknesser, the motor can be started up again.

Optional thicknesser table rolls (fig.8)
As an option the machine can be equipped with 1 or 2 rolls in the table.
In order to lower the rolls under the table simply pull the handle and lower, as
indicated on the pictogram.
fig.8
Maintenance
Attention: Always disconnect the machine from its power supply before starting
all maintenance works !!
The interior parts of the machine must be cleaned regulary in order to avoid an
accumulation of dust and woodchips.
Any possible deposit of resin on the various parts of the machine must be taken away
with a piece of cloth and a little solvent (petrol, kerosine or other product)
Never smoke or have any naked flame near the machine when using
inflammable products, this to prevent risk of fire and serious burns for the
operator !!
After removing the front, back, and side cover plates, all machine parts which need
maintenance are exposed.
The thread bars and posts of the table and the drive chains of both rise and fall of the
table and the feeding mechanism must be cleaned on a monthly base using a thin oil.
The use of a dust extractor system will most certainly extend the life of your machine.
The life of the motors can be extended by blowing out saw dust from the cooling fan
and from the motor body itself.

Change and tensionning of the belts (fig. 9)
The belts of the main motor can be tensionned as follows:
Unlock the 3 bolts which holds the motor-support bracket onto the frame and wind the
belt spanner bolt up or down in order to tension the belts.
After belt tensionning is done, lock again the 3bolts.
The drive belts are of the type: SPA 1750.

Tensionning the drive chain (fig.10)
The drive chains need no tensionning since the tension is always assured by an idle
chain spanner.
To change the drive chain, pull the chain spanner backwards and remove the chain
from the sprockets and remove the chains.
After the chain is replaced always assure the chain spanner is well placed onto the
chain.
To change the drive chain for the rise and fall of the table, pull the chain spanner lever
to the back and remove the chain.
Attention: do not turn the sprockets on one of the 4 posts of the table whilest
chainging the chain; this will lead into a disorder of the parallelism of the table!
Problems and troubleshooting
1. The machine does not start when the start button is activated :
- workshop main fuse is switched off: power cut, power shortage, or general overload.
- main switch off: put switch on “1”.
2. Reduction of cutting speed when working :
- belt tension not correct: tension the belt
- motor overload due to incorrect feed rate: reduce the feed rate
- blunt tools: sharpen tools
3. Vibration of the machine :
- worn or damaged belt: replace the belt
- overtensionned belt: loosen belt
4. Thermal overload does not re-arm automatically after shut-off and cooling down
period :
- overload is not set on automatic reset, or the overload is faulty: set on automatic, or
replace
