2. If necessary, fit ripping fence, locking screw
facing forwards.
3. Set cutting width with ripping fence.
4. Start saw.
5. Push the workpiece in a steady motion
towards the rear and cut in a single pass.
6. Switch the machine off if no further cutting is to
be done immediately afterwards.

11. Care And Maintenance

Danger!
Disconnect the mains plug before starting any
setting, maintenance or repair work.
Disconnect from the mains power before any
maintenance or cleaning work.
– Repair and maintenance work other than
described in this section should only be carried
out by qualified specialists.
– Replace damaged parts, in particular safety
installations, only with original parts. Parts not
approved by the equipment manufacturer can
cause unforeseeable damage.
– Check that all safety devices are operational
again after each service.

11.1 Saw blade change

Risk of burning!
Directly after cutting the saw blade can be very
hot. Let a hot saw blade cool down. Do not clean
the hot saw blade with combustible liquids.
Risk of injury, even with the blade at
standstill!
When loosening and tightening the tensioning
screw (45) the retractable blade guard (26) has
to be swivelled over the saw blade. Wear gloves
when changing blades.
1. Disconnect the mains plug. (see chapter 9.2).
2. Put the saw head in the upper position.
3. Lock saw blade: press the locking button (14)
and turn the saw blade with the other hand
until the locking button (14) engages. Hold
down the locking button (14).
4. Remove the tensioning screw with washer
(45) on the saw blade shaft with Allen key (4)
in clockwise direction (left-hand thread!).
5. Loosen safety lock (8) and push the
retractable blade guard (26) upwards and
hold.
6. Carefully remove outer flange (46) and saw
blade (47) from the saw blade shaft and close
again the retractable blade guard.
Danger!
Do not use cleaning agents (e.g. to remove resin
residue) that could corrode the light metal
components of the saw; the stability of the saw
would be adversely affected.
7. Cleaning the clamping surfaces:
– Saw blade shaft (50),
– saw blade (47),
– outer flange (46),
– inner flange (49).
Danger!
Place inner flange properly! If this is not the case,
the saw can block or the saw blade could work
loose. The inner flange is in the correct position if
the ring groove points towards the saw blade and
the flat side to the motor.
8. Put on inner flange (49).
9. Loosen safety lock (8) and push the
retractable blade guard (26) upwards and
hold.
10.Place a new saw blade - pay attention to
direction of rotation: Seen from the left (open)
side, the arrow on the saw blade has to
18
correspond to the direction of the arrow (48)
on the saw blade cover!
Danger!
Use only saw blades, which fulfil the requirements
and specifications listed in these operating
instructions.
Only use suitable blades, which are designed for
the maximum speed (see "Technical data") – is
unsuitable, damaged or defined blades are used,
parts may be thrown out as a result of the
centrifugal force.
Saw blades intended for cutting wood or similar
materials have to conform to EN 847-1.
Do not use:
– saw blades made of high-alloy speed steel
(HSS);
– damaged or deformed blades;
– cut-off wheel blades.
– Blades with a cutting width less than the
thickness of the splitting wedge or a main blade
width greater than the thickness of the splitting
wedge.
Danger!
– Mount saw blade using only genuine parts.
– Do not use loose-fitting reducing rings; the saw
blade could work loose.
– Saw blades have to be mounted in such way
that they do not wobble or run out of balance
and cannot work loose during operation.
11.Close again retractable blade guard (26).
12.Slide on outer flange (46) – The flat side has
to point towards the motor!
13.Put on the tensioning screw with the washer
(45) in anti-clockwise direction (left-hand
thread) and tighten by hand.
14.Lock saw blade: press the locking button (14)
and turn the saw blade with the other hand
until the locking button engages. Hold down
the locking button.
Danger!
– Do not extend the hexagon wrench.
– Do not tighten the tensioning screw by hitting
the hexagon wrench.
15.Firmly tighten the tensioning screw (45) using
the hexagon wrench (4).
16.Check function. Loosen the safety lock (8)
and fold the saw downwards:
– when folding down the retractable blade
guard, it has to provide free access to the saw
blade without touching other parts.
– When folding the saw upwards into the
starting position, the retractable blade guard
has to cover the saw blade automatically.
– Rotate the saw blade manually. You should be
able to rotate the saw blade into any possible
position without touching other parts.
11.2 Table insert change
Danger!
With a damaged table insert (33) there is a risk of
small parts getting stuck between table insert and
saw blade, blocking the saw blade. Replace
damaged table inserts immediately!
1. Remove screws at table insert. If required,
rotate turntable and incline saw head to be
able to reach the screws.
2. Remove table insert.
3. Insert new table insert.
4. Tighten the screws at the table insert.
11.3 Adjust parallel guide/ripping fence
1. Loosen Allen screws (51).
2. Adjust the parallel guide/ripping fence (27) in
such a way that it is exactly perpendicular to
the saw blade when the turntable engages in
the 0° position.
3. Tighten the Allen screws (51).

11.4 Cleaning the device

Remove chips and saw dust with vacuum cleaner
or brush from:
– adjustment installations
– controls;
– motor vent slots;
– space under table insert;
– cutting laser;
– Cutting line illumination
11.5 Storage of device
Danger!
 Store the device in such a way that it cannot be
put into operation by unauthorised personnel.
 Ensure that the stationary device cannot cause
injury.
Caution!
 Do not store the tool outdoors or in damp
conditions without protection.
 Observe permissible ambient conditions (see
chapter 17. Technical Data).
11.6 Maintenance
Prior to each use
 Remove saw chips with vacuum or brush.
 Check power cable and power cable plug for
damage; if necessary have damaged parts
replaced by a qualified electrician.
 Check all movable parts if they can be moved
freely across the entire range of movement.
 Always work with a properly set splitting wedge.
Check whether the riving knife – blade distance
is between 3 mm and 8 mm. If necessary, repair
before using the device.
 Check whether the retractable blade cover (26)
works properly and does not stick. It has to
provide free access to the saw blade without
touching other parts. When folding the saw
upwards into the starting position, it has to cover
the saw blade automatically. If parts are
damaged or not working correctly, have the
device repaired before using.
 Check the table insert (33). A damaged table
insert must be replaced immediately.
 Check whether the protective equipment is in
the envisaged position, particularly after a
refitting a table saw to a chop and mitre saw. If
parts are damaged or not working correctly,
have the device repaired before using.
Regularly, depending on conditions of use
 Regularly check the power cable on the power
tool and have repaired by an approved expert if
damaged.
 Regularly check extension cables and replace if
damaged.
 Check all screwed joints, retighten if necessary.
 Check reset function of the saw head (saw head
has to return to the upper starting position by
means of spring force), if required have spring
replaced.
 Slightly oil guide elements.

12. Tips and Tricks

– Use appropriate supports on the left and right of
the saw for long workpieces.
– Hold workpiece on the right of the saw blade for
suitable cuts.
– When cutting small pieces, use additional guide
(a suitable wooden board attached with screws
to the guide of the device, can be used as
additional guide).
– When cutting a curved (contorted) board (52)
place the convex side at the parallel guide/
ripping fence.
– Do not cut workpiece upright, but flat on the
turntable.
– Keep surfaces of the supporting tables clean –
in particular remove resin residue with an
appropriate cleaning and care spare.
