the underside.
9.10 Replacing the saw blade (Fig. 14 - 17)
Pull out the mains plug!
Attention! Wear protective gloves when changing
the saw blade! Danger of injury!
• Swivel the machine head (19) upwards.
• Loosen the screw (f) of the flange cover so that it
can move freely.
• Fold the saw blade guard (4) up sufficiently that
the recess in the saw blade guard (4) is above the
flange screw (34).
• With one hand, fit the Allen key (c) to the flange
screw (34).
• Firmly press the saw shaft lock (20), and slowly
turn the flange screw (34) clockwise. After max.
one turn, the saw shaft lock (20) engages.
• Then undo the flange screw (34), by applying a
slightly greater force in a clockwise direction.
• Fully unscrew the flange screw (34) and remove the
outer flange (33).
• Remove the saw blade (35) from the inner flange
(36) and pull it out downwards.
• Carefully clean the flange screw (34), outer flange
(33) and inner flange (36).
• Insert the new saw blade (35) in the reverse se-
quence and tighten.
• Attention! The cutting angle of the teeth, i.e. the di-
rection of rotation of the saw blade (35), must corre-
spond to the direction of the arrow on the housing.
• Move the guide bar into position and tighten the
screw (f) again.
• Before continuing work, check that the safety de-
vices are functioning properly.
• Attention! After each saw blade change, check that
the saw blade (35) runs freely in the table inlay (9)
in vertical position as well as when tilted to 45°.
• Attention! Changing and aligning the saw blade (35)
must be carried out properly.
9.11 Laser/LED operation (Fig. 18)
• Press 1x: Laser ON / LED OFF
• Press 2x: Laser OFF / LED ON
• Press 3x: Laser ON / LED ON
• Press 4x: Laser OFF / LED OFF

9.12 Calibrating the laser (Fig. 13)
If the laser (17) is no longer showing the correct cutting
line, it can be readjusted.
Loosen the laser screws (32) and adjust the laser by
sliding it sideways such that the laser beam hits the
cutting teeth of the saw blade (35).
10. Transport (Fig. 1, 3, 4)
• To lock the rotary table (14), turn the locking knob
(10) clockwise.
• Push the machine head (19) downwards and lock it
with the locking pin (21). The saw is now locked in
the lower position.
• Fix the saw's slide function with the locking screw
for slide rail guide (26) in rear position.
• Carry the machine by the fixed saw table (8).
• To reassemble the machine, proceed as described
in 9.1.
11. Maintenance
m WARNING! Pull out the mains plug before carrying
out any setting, servicing or repair work!
General maintenance tasks
Wipe swarf and dust off the machine from time to time
with a cloth. Oil the rotating parts once monthly to ex-
tend the life of the tool. Do not oil the motor.
Do not use corrosive agents for cleaning the plastic.
Brush inspection
If the machine is new, check the carbon brushes after
the first 50 operating hours or if a new brush has been
mounted. After the initial check, check every 10 oper-
ating hours.
If the carbon is worn down to a length of 6 mm, or the
spring or the shunt wire is burnt or damaged, both
brushes must be replaced. If the brushes are found to
be usable after removal, they can be reinstalled.
Replacing the table inlay
Danger!
With a damaged table inlay (9) there is a risk of small
parts jamming between table inlay (9) and saw blade
(35) and jamming the saw blade (35).
Immediately replace damaged table inlays (9)!
• Unscrew the screws on the table inlay (9). If re-
quired, turn rotary table (14) and incline machine
head (19) to be able to reach the screws.
• Remove the table inlay (9).
• Install new table inlay (9).
• Tighten the screws on the table inlay (9) again.
12. Cleaning
m WARNING! Pull out the mains plug before cleaning!
• Keep protective devices, air vents and the motor
housing as free of dust and dirt as possible. Rub the
product clean with a clean cloth or blow it off with
compressed air at low pressure.
• We recommend that you clean the product directly
after every use.
• Clean the product at regular intervals using a damp
cloth and a little soft soap. Do not use any cleaning
products or solvents; they could attack the plastic
parts of the product. Make sure that no water can
penetrate the interior of the product. Water penetra-
tion increases the risk of an electric shock.
13. Storage
• Store the product and its accessories in a dark, dry
and frost-free place that is inaccessible to children.
• The optimum storage temperature is between 5 and
30˚C.
• Store the product in its original packaging.
• Cover the product to protect it from dust or moisture.
• Store the operating manual with the product.
14. Electrical connection
The electrical motor installed is connected and
ready for operation. The connection complies with
the applicable VDE and DIN provisions. The cus-
tomer's mains connection as well as the exten-
sion cable used must also comply with these reg-
ulations.
• The product fulfils the requirements of EN 61000-3-11
and is subject to special connection requirements.
This means that use at any freely selectable connec-
tion points is not permitted.
• Given unfavourable conditions in the power supply
the product can cause the voltage to fluctuate tem-
porarily.
• The product is only intended for use at connection
points that
a) do not exceed a maximum permissible mains im-
pedance of "Z" (Zmax = 0.407 Ω), or
b) have a mains constant current carrying capacity
of at least 100 A per phase.

• As the user, you are required to ensure, in consulta-
tion with your electric power company if necessary,
that the connection point at which you wish to oper-
ate the product meets one of the two requirements,
a) or b), named above.
Important information
In the event of overloading, the motor will switch itself
off. After a cool-down period (time varies) the motor
can be switched back on again.
Damaged electrical connection cable.
The insulation on electrical connection cables is often
damaged.
This may have the following causes:
• Pressure points, where connection cables are
passed through windows or doors.
• Kinks where the connection cable has been improp-
erly fastened or routed.
• Places where the connection cables have been cut
due to being driven over.
• Insulation damage due to being ripped out of the
wall outlet.
• Cracks due to the insulation ageing.
Such damaged electrical connection cables must not
be used and are life-threatening due to the insulation
damage.
Check the electrical connection cables for damage
regularly. Ensure that the connection cables are dis-
connected from electrical power when checking for
damage.
Electrical connection cables must comply with the ap-
plicable VDE and DIN provisions. Only use connection
cables of the same designation.
The printing of the type designation on the connection
cable is mandatory.
AC motor:
• The mains voltage must be 220 - 240 V~.
• Extension cables up to 25 m long must have a
cross-section of 1.5 mm².
Connection type X
If the mains connection cable of this product is dam-
aged, it must be replaced by a specially prepared
mains connection cable which can be obtained from
the manufacturer or its service department.
