3. Loosen the left screw of the tensioning-screw-
cover (44). Swivel the tensioning-screw-cover
(44) upwards and unhook, then swivel
downwards.
4. Lock saw blade: press the locking button (18)
and turn the saw blade with the other hand
until the locking button engages. Hold down
the locking button.
5. Remove the tensioning screw with washer
(45) on the saw blade shaft with Allen key
(14) in clockwise direction (left-hand thread!).
6. Loosen safety lock (27) (only for mains-
powered devices) and push the retractable
blade guard (6) upwards and hold.
7. Carefully remove outer flange (46) and saw
blade (47) from the saw blade shaft and close
again the retractable blade guard.
WARNING
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.
8. Cleaning the clamping surfaces:
– Saw blade shaft (50),
– saw blade (47),
– outer flange (46),
– inner flange (49).
WARNING
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.
9. Put on inner flange (49).
10.Loosen safety lock (27) (only for mains-
powered devices) and push the retractable
blade guard (6) upwards and hold.
11.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
correspond to the direction of the arrow (48)
on the saw blade cover!
WARNING
Use only saw blades, which fulfil the requirements
and specifications listed in these operating
instructions.
Use only saw blades designed for the maximum
speed (see "Technical Specifications") – if
unsuitable or damaged saw blades parts are
used, parts can be ejected due to centrifugal
force in an explosive-type manner.
Do not use:
– saw blades made of high-alloy speed steel
(HSS);
– damaged saw blades;
– cut-off wheel blades.
WARNING
– 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.
12.Close again retractable blade guard (6).
13.Slide on outer flange (46) – The flat side has
to point towards the motor!
14.Put on the tensioning screw with the washer
(45) in anti-clockwise direction (left-hand
thread) and tighten by hand.
15.Lock saw blade: press the locking button (18)
and turn the saw blade with the other hand
until the locking button engages. Hold down
the locking button.
WARNING
– Do not extend the hexagon wrench.
– Do not tighten the tensioning screw by hitting
the hexagon wrench.
16.Firmly tighten the tensioning screw (45) using
the hexagon wrench (14).
17.Swivel the tensioning-screw-cover (44)
upwards and fix again with the left screw.
18.Check function. Loosen the safety lock (27)
(only for mains-powered devices) 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.
9.2 Table insert change
WARNING
With a damaged table insert (10) 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.
9.3 Adjust parallel guide/ripping fence
1. Loosen Allen screws (51).
2. Adjust the parallel guide/ripping fence (26) 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).
9.4 Adjust the cutting laser
Align the laser perpendicularly
– Loosen the middle screw (41). Rotate laser.
Tighten the middle screw (41).
Align laser laterally
– Loosen the right (43) and the left screw (42).
Shift the laser horizontally. Tighten the right (43)
and left screw (42).
9.5 Cleaning the tool
Remove chips and saw dust with vacuum cleaner
or brush from:
– adjustment installations
– controls;
– motor vent slots;
– space under table insert;
– cutting laser;
– illumination of cutting line
9.6 Storage of device
WARNING
Store the device in such a way that it cannot be
put into operation by unauthorised personnel.
The hole in the switch should be used to secure
the machine with a padlock from being switched
on by unauthorised persons.
Ensure that the stationary device cannot cause
injury.
CAUTION
Do not store the tool outdoors or in damp
conditions without protection.
9.7 Maintenance
Prior to each use
Remove saw chips with vacuum or brush.
Check power cable and power cable plug or
battery pack 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.
Regularly, depending on conditions of use
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.
10. 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 (54)
place the convex side at the parallel guide/
ripping fence.
– Do not cut workpiece upright, but flat on the
turntable.
