7. Setup and adjustments
General note:
Setup and adjustment work may only be carried out after
the machine is protected against accidental starting by
pulling the mains plug.
7.1 Changing sawblade
The sawblade has to meet the technical specification.
Use only sawblades according to EN 847-1
The minimum diameter of the saw blades used on the
machine is 250mm.
The maximum diameter of the saw blades used on the
machine is 315mm.
Check sawblade for flaws (cracks, broken teeth, bending)
before installation. Do not use faulty sawblades.
Warning:
The use off HSS saw blades is prohibited; use only carbide
tipped saw blades.
The sawblade teeth must point in cutting direction (down)
Always wear suitable gloves when handling sawblades.
WARNING:
When installing or changing saw blade, always disconnect
saw from power source, unplug!
Push the sliding table to the front and open the lower
sawblade cover.
Raise the main sawblade to its highest position.
Remove the saw guard.
Changing main saw blade:
Loosen the arbor nut (J, Fig 23) while stopping the arbor
against rotation with the locking pin (K).
Fig 23
Attention: left hand thread.
Remove the arbor nut (J) and flange (I).
Place saw blade on arbor shaft making sure teeth point down
at the front of the saw.
Reinstall flange and arbor nut and securely tighten.
Remove the locking pin (K).
Check the correct position of the raving knife in regards to
the saw blade (see Chapter 7.2).
Reinstall the saw guard.
The scoring sawblade is changed as follows:
Put the enclosed spanner onto the saw arbor nut (M, Fig 24)
Fig 24

Put the locking pin (N) in the opening
of the saw table and turn the arbor with the spanner until the
locking pin engages in the hole in the saw arbor pulley.
Now unlock the nut.
Change the scoring blade.
After changing the blade tighten the bolt.
7.2 Mounting the raving knife
The supplied raving knife must always be used.
The machine is equipped with a raving knife for the use of
sawblades diameter 250 to 315 mm.
The raving knife has to be adjusted in such a way that over
its entire length the gap between sawblade and raving knife
does not exceed min.3 mm and max.8 mm. (Fig 25).
Fig 25
The raving knife (P, Fig 26) can be adjusted in both vertical
and horizontal direction.
The height setting has to be adjusted in such a way that the
sawguard bottom never exceeds more than 3 mm above the
highest placed sawblade tooth.
After height adjustment always locks the central bolt (Q).
The raving knive is side adjusted ex works.
The 4 little adjustment screws are used for the exact setting
of the raving knife in line with the sawblade.
For slotting or grooving a special raving knife is needed.
The raving knife has to be adjusted in such a way that the
upper part of the raving knife is never set lower than the
highest sawtooth in use.
Never remove this raving knife.
Kickbacks are severe and very dangerous.
No submerged cuts by removing the raving knife and/or saw
guard may be performed.
7.3 Mounting the saw guard
The sawguard (O, Fig 26) must always be used.
Attach the saw guard to the raving knife (P), in the slot (S)
matching the sawblade diamenter.
The sawguard must be lowered to the workpiece to minimise
the amount of exposed teeth.
Fig 26
Adjustment shall never be performed when the machine is
running.
The saw guard has to be connected to the dust extractor
system.
7.4 Rising and tilting sawblade
Setup adjustments of the sawblade shall never be performed
when the machine is running.
Use the front handwheels to raise the sawblade (1, Fig 27).
One turn of the handwheel equals 7.5 mm of height setting.
Loosen the lock knob (3) to adjust.

Fig 27
Use the left handwheel to tilt the sawblade (2).
Both 45°and 90°positive stops are factory set.
In case, they are adjustable, loosen the grub screw and
reposition the stop collar (Fig 28).
Fig 28
After any adjustment, start the machine with care.
7.5 Setup of scoring sawblade
The height setting of the scorer sawblade is done by turning
the screw (T, Fig 29)
Fig 29
The maximum cutting depth using a scorer sawblade
diameter of 90 mm is 4 mm .
Each time the main sawblade is replaced by a new one, or
even a newly sharpened sawblade, the scorer has to be
adjusted to match the main sawblade teeth width.
It is very important that this is done in the correct way to
ensure a clean cut, free of splintering.
The supplied scoring sawblade has tapered teeth. Cutting
depth also adjusts cutting width.
Before any lateral adjustment can be done the lateral lock (R)
has to be loosened.
The lateral movement of the scorer sawblade is achieved by
turning the excenter (S), lock again after adjustment (R).
7.6 Sliding table setup
When loading panels and when cutting using the parallel
fence the sliding table should be locked.
To lock the table engage the index pin on the front end of the
sliding table.
If over a long period of time many short movements of the
sliding table are made by e.g. crosscutting solid wood, then it
is possible that the ball carrier between the upper and lower
part of the sliding table will move.
This means it will no longer be correctly positioned to allow
the sliding table to slide through its full course.
The operator will feel resistance in the sliding table motion
and the full stroke will not be achieved.
This effect can be corrected simply by pushing the table with
a few short, light pushes against the buffer stop at the end,
until the position of the ball carrier is adjusted and the table
can be moved again along its full stroke.
It is recommended to clean the sliding table once a week,
and to remove all sawdust and chips which gradually slow
down the sliding table.
After all dust has been blown off, thin oil, such as WD-40,
should be sprayed onto the steel guide rods on both the
upper and lower part of the sliding table.
Never use a thick oil or grease!
7.7 Crosscut table setup
Crosscut table setup shall never be performed when the
machine is running.
Lift the crosscut table onto telescopic arm support and slide
onto sliding table T-groove and lock in place. Fig 30
Fig 30

Crosscut table and telescopic arm are aligned ex works (The
table surface must be in level with the sliding table).
The crosscut table can be positioned along the sliding table.
Start the machine with care.
7.8 Crosscut fence setup
Crosscut fence setup shall never be performed when the
machine is running.
The cross-cut table has 2 precision holes, allowing the
crosscut fence to be put in 2 positions:
At the back and front of the cross-cut table.
Simply put the fence onto the crosscut table and lock it in
position using the two knobs. Fig 31.
Fig 31
The 90°adjustable stops are factory set.
Calibration of the scale on the crosscut fence:
The scale on the fence is factory set and needs no further
adjustments.
To check the settings, put the stop at a certain measure and
cut off a sample.
Measure the exact length of the sample, unlock the screw
which holds the fence pivoting T-nut and move the fence
until the measurement corresponds to the length of the
previously cut length.
When using the telescopic extension, the material stop has
to be set to the very end to make the different scales
correspond with one another.
The best way to check that all scales correspond, is to make
several test cuts on the different scales.
7.9 Mitre fence setup
Mitre fence setup shall never be performed when the
machine is running.
For good workpiece support, the fence profile must be set
close to the saw blade (Fig 32)
Fig 32
7.10 Rip fence setup
Rip fence setup shall never be performed when the machine
is running.
To move the fence, lift the handle (1, Fig 33) halve way.
Fig 33
When cutting small workpieces or with the sawunit inclined
at 45°, the fence profile must be used in the low position.
(Fig 34).
Fig 34

The rip fence has a micro adjust feature. Lift the handel (1)
fully and rotate the micro adjust knob (4)
When cross cutting using the parallel fence, to avoid the
wood getting stuck between the fence and the riving knife
(resulting in a highly dangerous kickback) it is necessary to
position the fence so that its end corresponds with the front
of the sawblade. (Fig 35).
Fig 35
Start the machine with precaution.
The rip fence must be parallel to the sawblade and is
adjusted at the factory.
8. Maintenance and inspection
General notes:
Maintenance, cleaning and repair work may only be
carried out after the machine is protected against
accidental starting by pulling the mains plug.
Repair and maintenance work on the electrical system may
only be carried out by a qualified electrician.
Clean the machine regularly.
Inspect the proper function of the dust extraction daily.
Keep the inside of the cabinet clear of sawdust and wood
chips. Make sure the motor fan and fan cover are also kept
clear of sawdust.
After a days use push the sliding table all of the way forward
and backward.
Remove rust from the table e.g. with
WD-40 and a Scotch-Brite™ Hand Pad.
Never smoke while cleaning the machine, and especially
when using petrol, kerosene or other inflammable products.
This could lead to an explosion and serious burns for the
operator.
All protective and safety devices must be re-attached
immediately after completed cleaning, repair and
maintenance work.
Defective safety devices must be replaced immediately.
Check saw blades regularly for faults.
Replace a defective sawblades immediately.
A worn table insert must be replaced.
A worn crosscut fence end cap must be replaced.
Main drive belt tensioning:
Check regularly the condition of the belts and, if necessary,
tighten or replace.
Remove the rear machine access door.
Tension the belt by pushing the motor down with the
tensioning screw (B, Fig 36).
Fig 36
Make sure the belt is not over tensioned, because this could
lead to damage of the saw arbor and bearings.
Main drive belt changing:
Move the blade tilt to 0˚ (Blade 90˚ to table) on the control
panel and raise the blade as far as it will go.
Move the sliding panel all the way to the left and remove two
M6x12 pan head screws to expose the internal blade guard
that covers the blades and riving knife.
Remove the blade guard from the riving knife to expose the
mounting assembly.
Remove the main blade.
Remove M8 Allen screws and remove the inner chip house.
(Fig 37).
Fig 37
Note: for better access, tilt the saw blade.
Loosen the belt tension and remove the belt. (Fig 38).
Fig 38

Replace new V-belt, tension belt, close the left panel, and re-
mount inner chip house, blade, blade guard.
Reattach the rear machine access door.
Scoring unit belt tensioning:
The scoring unit belt is self tensioning by spring load (Fig 39).
Fig 39
Scoring unit belt changing:
Move the blade tilt to 0˚ (Blade 90˚ to table) on the control
panel and lower the blade as far as it will go.
Remove the 4 Allen screws on the top and bottom of right
panel, and remove the left panel.
Push the tension pulley against the spring load.
Remove the old belt and replace new belt.
Re-mount the right panel.
Motor Break:
The motor break works electro-mechanically (break motor).
