1. Introduction
The Ceetec Sandingmachine IS-250 is built to effective sanding of wood like profiles, lists, panels, etc.
The machine is equipped with sanding heads, where one of the advantages, among others is the
modular sanding heads, there can be combined in countless ways. Furthermore a replacement of polish
can be done without demounting the axles and heads.
The planks will be led all the way through the machine by the automatically forward drive system and the
speed can be step less regulated by a frequency changer. Furthermore it is possible to individually
adjust the conveying speed, and the sanding heads speed, which gives a perfect result.
The machine is developed by the same concept as our Paintingmachine line, where the keywords are
flexibility, efficient and simplicity.
If you wish to both sand and paint, it will be to your advantage to mount a Ceetec IS-250 in front of the
Ceetec A-250, and thereby both processes will be done in the same workflow.

2. Safety instructions
Important:
The following safety instructions must be adhered to for reasons of personal safety.
All users must be familiar with these user instructions. Read thoroughly before use to know the
machine functions entirely.
BEFORE the machine is used, the safety guard delivered with the machine must be mounted in the
inlet. See pictures. Affix the safety guard with the bolts supplied. Failure to mount the safety guard or the
removal during operation may result in personal injury.
Mount the safety guards in
the inlet and outlet.
2.1 Use of machine
The machine is only to be used for sanding wood and composites material. The machine is not suitable
for sanding metal objects.
2.2 Ventilation
Always make sure that relevant ventilation is attached to pipes in lid and bottom of the machine. Misuse
can lead to airway genes.
2.3 Risks during use
Keep hands, etc., away from the machine inlet when the machine is running to avoid the risk of
crushing.
The noise level of the machine during normal use is not over 70 dB. Therefore earplugs are not required
during normal use.
Please note that the wood is forwarded in high speed, and thereby can cause personal injury on the
operator that receives the polished wood.
If a Ceetec Paintingmachine is mounted in extension of the Sandingmachine, they have to be combined
by Ceetec roller conveyors. If this is not respected, there is a risk of the wood colliding on its way into
the Paintingmachine, and thereby pushes the sanding machine back, with danger of personal injury.
2.4 Moving the machine
The machine can be moved around on the mounted rubber-wheels or by forklift. Before moving the
machine all cables and ventilation has to be demounted.

5/29
When moving by forklift: Be aware that the forklift lifts under the contrived lifting marks.
When moving manually: Be aware that all needless gear has been taken out of the machine, and the
machine is in god balance. Never try moving the machine manually on hilly ground.

4. Preparing the machine for use
Place the machine on a flat, firm surface. Lower the four support legs so that the machine stands stable.
The control panel can be placed under the machine during transportation to protect it from impact. The
control panel is mounted on the side of the machine using 4 screws.
The machine must NOT be used before the safety tunnels are mounted. The safety tunnels are placed
under the machine during transport to protect them. Mount the tunnels at each end of the machine,
using 4 screws on each tunnel. If it is not mounted or demounted during use, personal injury can occur.
Mount the safety guards in
the inlet and outlet.
The machine is attached to the power station following the local regulations. If it turns out to be
necessary changing the plug, the directions from the supplier must be followed. This job is only to be
done by a competent electrical specialist.
OBS! Please note that the machine needs 3 x 380 V and 0.
Emergency stop
Normally a person on each end operates the machine. In cause of accident either by the inlet or in
danger of getting hit or getting caught by wood on its way in or out of the machine, you can prevent this
by activating the emergency stops, which are placed by the operator on both ends.
When an emergency stop is activated the forward drive is stopped.
After activating the emergency stop, the machine can only be restarted by unlocking the emergency
stop and activating the start button again. NB: Before starting the machine again make sure that the
incident has come to an end, and that the reason for activating the emergency stop is known.
Stop
During normal use, the machine is stopped by the buttons “FREMTRÆK/PULL and
“BØRSTER/SANDING” put in “0” position.
This function is normally used with stop with beaks, change of dimensions etc.
When the machine is stopped, in order to be moved, repaired e.g. the main switch on the control panel
must be turned to position “0”. (Power is off.)

8/29
5. Adjusting the machine
The main switch on the control panel must be in position "O". (The machine is disconnected
from all power.)
NB: During the process, you have to take notice of scarp edges in the machine, which may cause
personal injury.
5.1 The lid on the machine is opened
Set the feeder guide, guide, backpressure roller and brushes to the outer position. Feed the item into the
machine.
5.2 Feeder guide and the guide in the middle of the machine
The feeder guides (pos 9015-20535, picture B/C) guides the item sideways and the roller in front of the
machine guides the item horizontally. Adjust the guides by loosening the wing screws and moving them
towards the item. There must be a 2-3 mm gap on both sides.
5.3 Sanding heads, brushes and screens/shields
The rotating sanding heads (horizontally and vertical) is adjusted so the wanted sanding effect is
achieved. The brush pressure is individually and depends of the treatment and the items profile. Ask if
necessary your sanding supplier for guidance.
The brushing (pos 9011-20567, picture A) is adjusted with the needed pressure, so dust will be removed
and collected in the brush shield (pos 9015-20538, picture D). Also here the brushing pressure is
individually. The brushing is produced in durable nylon.
The brushes can be mounted and demounted with a single grip. (See picture E)
The sanding heads can be mounted and demounted by loosen the 3 stopscrews and pull the lock
washer of. (See picture F and G)
The adjustment of the horizontally sanding heads and brushes is done by leading the pole into the
square pipe on the brush module. (See picture H)
The adjustment of the vertical sanding heads is done by leading the square pipe, plus the pole down
over the square pipe on the sanding head module. (See picture I)

9/29
5.4 Forward drive
The forward drive propels the item through the machine. Adjust the backpressure roller by turning the
spindle using the handle. (See picture J)
Turning clockwise: the backpressure roller is moved upwards
Turning anti-clockwise: the backpressure roller is moved downwards
Bring the backpressure roller into contact with the item and tighten up approx. 1 turn, depending on how
hard the item is.
5.5 Test run and flow rate
1) Pull the item out.
Position the main switch on the control panel to "I" (power is connected). (See picture K)
2) Aktiver knappen ”Børster/Sanding” og hovederne begynder at rotere. Indstil den ønskede hastighed
på knap (See picture K)
3) Activate the button ”Fremtræk/Pull” and adjust the forward drive to the desired speed with the
adjusting knob. (See picture K)
Feed the item into the inlet and check that the forward drive is running evenly.
If forward drive is not running evenly, adjust the backpressure roller. (See picture J)
The item can stop moving, if it hits the feeder guide, guide or brushes. In that case they should be re-
adjusted.
If the wood bends a lot, a problem can occur in the passage, because the wood will get stuck between
brush heads and guide. Therefore the wood has to be as plain as possible.
Test-drive with the same item 2-3 times. This is to make sure, that the machine is adjusted correctly.
Then make a test with a new item. If the result is satisfying, the machine is ready to use. Afterwards the
running is normal, however it is a good idea to check an item from time to time.

10/29
5.6 Opening the lid
NOTE THAT THE MACHINE, FOR SAFETY REASONS STOPS, WHEN YOU OPEN THE LID.
Attention: The lid on the forward drive and brushes is hinged and can be opened.
The lid is connected to a switch, which stops the forward drive, if the lid is open.
To start the forward drive the lid must be closed. If the lid is opened while the machine is activated the
forward drive stops immediately. To restart the machine the lid must be closed and a new start
command must be given on the start button.
5.7 Reversing of circulation direction on the sanding heads
To obtain the wanted sanding result, the circulation direction on the 2nd horizontally sanding can be
reversed (the sanding head is attached to the arrangement with pos. 9015-20522, spare part picture A)
As standard, the machine is configured to both horizontal sanding heads running against the item's
travelling direction.
The circulation direction can only be reversed by the before mentioned horizontal sanding head. Thus
can the circulation direction not be changed on any on the vertical sanding heads.
Procedure for changing the circulation direction (when configured to running against the wood):
Before the replacement can begin, the main switch must be turned to position ”0” and the plug removed.
1. Demount the sideplate, so access to the machines transmissions elements is achieved (spare
part picture C)
2. The tightenwheel is loosen from pos. A (see picture N). The toothed belt (pos. 9015-20525) is
demounted and placed in the opposite direction around the pulley (see picture Q). The tighten
roll is then mounted again in pos. B (see picture P) and the belt is tighten.
