9.5 90° chop cut and rotary table 0°- 45°
(Fig. 1, 12)
Angled cuts of 0° - 45° to the stop rail to the left and
right can be carried out with the chop saw.
Attention! For 90° mitre cuts, the moveable stop rail
(5) must be fixed in the inner position.
• Loosen the locking screw (16) for the moveable stop
rail (5) and push the moveable stop rail (5) inwards.
• The moveable stop rail (5) must be locked in a po-
sition far enough from the inner position that the
distance between the stop rail (5) and the saw blade
(35) is no more than 5 mm.
• Before making the cut, check that no collision could
occur between the stop rail (5) and the saw blade
(35).
• Tighten the set screw (16) again.
• Turn the locking knob (10) counter-clockwise and
pull the lower indexed position lever (11) upwards
with your index finger.
• Use the locking knob (10) to adjust the rotary table
(14) to the desired angle. The pointer (12) on the
rotary table (14) must match the desired angle on
the scale (13) on the fixed saw table (8).
• Turn the locking knob (10) clockwise to fix the rotary
table (14) in place.
• Make a cut as described in point 9.4.
9.6 0°- 45° mitre cut and rotary table 0°
(Fig. 1, 2, 5, 11)
Mitre cut of 0° - 45° to the stop rail to the left and right
can be carried out with the chop saw.
Attention! For bevel cuts (inclined saw head), the
moveable stop rail (5) must be fixed in the outer po-
sition.
• Loosen the locking screw (16) on the moveable
stop rail (5) and push the moveable stop rail (5)
outwards.
• The moveable stop rail (5) must be locked in a po-
sition far enough from the inner position that the
distance between the stop rail (5) and the saw blade
(35) is at least 5 mm.
• Before making the cut, check that no collision could
occur between the stop rail (5) and the saw blade
(35).
• Tighten the set screw (16) again.
• Move the machine head (19) to the upper position.
• Fix the rotary table (14) in the 0° position.
• Loosen the locking screw (24) and tilt the machine
head (19) to the left with the handle (1) until the
pointer (23) points to the desired angle on the scale
(22).

• Retighten the locking screw (24).
• Make a cut as described in point 9.4.
9.7 0°- 45° mitre cut and rotary table 0°- 45°
(Fig. 1, 2, 6, 12)
The chop saw can be used for mitre cuts of 0°- 45° to
the left and right of the work surface and of 0°- 45° to
the stop rail (double mitre cut).
Attention! For bevel cuts (inclined saw head), the
moveable stop rail (5) must be fixed in the outer po-
sition.
• Loosen the locking screw (16) on the moveable
stop rail (5) and push the moveable stop rail (5)
outwards.
• The moveable stop rail (5) must be locked in a po-
sition far enough from the inner position that the
distance between the stop rail (5) and the saw blade
(35) is at least 5 mm.
• Before making the cut, check that no collision could
occur between the stop rail (5) and the saw blade
(35).
• Tighten the set screw (16) again.
• Move the machine head (19) to the upper position.
• Turn the locking knob (10) counter-clockwise and
pull the lower indexed position lever (11) upwards
with your index finger to release the rotary table.
• Use the locking knob (10) to adjust the rotary table
(14) to the desired angle (see also point 9.5).
• Turn the locking knob (10) clockwise to fix the rotary
table (14) in place.
• Loosen the locking screw (24) and use the handle
(1) to tilt the machine head (19) to the left to the de-
sired angle (see also point 9.6).
• Retighten the locking screw (24).
• Make a cut as described in point 9.4.
9.8 Restricting the cutting depth (Fig. 3)
• The cutting depth can be seamlessly adjusted with
the screw (27). To do so, loosen the knurled nut
on the screw (27). Set the desired cutting depth
by screwing in or unscrewing the screw (27). Then
retighten the knurled nut on the screw (27).
• Check the setting with a test cut.
9.9 Dust bag (Fig. 1)
• The saw is equipped with a dust bag (18) for saw-
dust.
• Squeeze the wings of the metal ring on the dust
bag (18) together and slide it over the discharge
port near the motor.
• The dust bag (18) can be emptied via the zip on
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).
