– Position the workpiece so that the teeth of the saw blade
line up with the cutting line.
– Hold the workpiece in this position and slowly guide the
glide arm upwards.
– Clamp the workpiece.
– Switch on the laser beams with the switch .
The laser beams must be the same distance away (left and
right) from the cutting line marked on the workpiece along
their entire length, even when lowering the glide arm.
Setting (see figure T2)
1. Adjusting the right-hand laser beam:
– Turn the right-hand set screw (67) using the hex key (18)
until the entire length of the right-hand laser beam is flush
with the cutting line marked on the workpiece.
This also moves the left-hand laser beam.
One rotation anticlockwise moves the laser beam from left to
right; one rotation clockwise moves the laser beam from
right to left.
2. Adjusting the left-hand laser beam:
– Turn the left-hand set screw (67) using the hex key (18)
until the left-hand laser beam is the same distance away
from the cutting line marked on the workpiece as the
right-hand laser beam.
One rotation anticlockwise moves the laser beam from left to
right; one rotation clockwise moves the laser beam from
right to left.
Setting the Standard 0° Bevel Angle
– Bring the power tool into the transport position.
– Turn the saw table (41) to the 0° detent (15). The lever
(13) must be felt to engage in the detent.
Checking (see figure U1)
– Set an angle gauge to 90° and place it on the saw table
(41).
The leg of the angle gauge must be flush with the saw blade
(43) along its entire length.
Setting (see figure U2)
– Loosen the clamping handle (14).
– Loosen the two set screws (68) (by at least one turn) us-
ing a socket spanner (10 mm).
– Loosen the set screw (70) (by approx. three turns) using
the hex key (4 mm) (17).
– Tighten or loosen the set screw (69) using the hex key (4
mm) (17) until the leg of the angle gauge is flush with the
saw blade along its entire length.
– Retighten the clamping handle (14). Then tighten the set
screw (70) followed by the set screws (68).
If the angle indicators (36) and (21) are not in line with the
0° marks on the scale (35) following adjustment, loosen the
fastening screws on the angle indicators using a cross-
headed screwdriver and align the angle indicators with the
0° marks.
Setting the Standard 45° Mitre Angle (left)
– Bring the power tool into the work position.
1 609 92A 5HG | (08.04.2020)
– Turn the saw table (41) to the 0° detent (15). The lever
(13) must be felt to engage in the detent.
– Pull the left-hand adjustable fence (6) all the way out.
– Loosen the clamping handle (14) and swivel the glide arm
to the left stop (45°) by the handle (1).
Checking (see figure V1)
– Set an angle gauge to 45° and place it on the saw table
(41).
The leg of the angle gauge must be flush with the saw blade
(43) along its entire length.
Setting (see figure V2)
– Tighten or loosen the set screw (71) using an open-ended
spanner (8 mm) until the leg of the angle gauge is flush
with the saw blade along its entire length.
– Retighten the clamping handle (14).
If the angle indicators (36) and (21) are not in line with the
45° marks on the scale (35) following adjustment, first
check the 0° setting for the bevel angle and the angle indicat-
ors once more. Then repeat the adjustment of the 45° bevel
angle.
Setting the Standard 45° Mitre Angle (right)
– Bring the power tool into the work position.
– Turn the saw table (41) to the 0° detent (15). The lever
(13) must be felt to engage in the detent.
– Pull the right-hand adjustable fence (6) all the way out.
– Loosen the clamping handle (14).
– Use the handle (1) to tilt the glide arm slightly to
the left from the 0° position and turn the rotary
knob (42) until the right-hand bevel angle range is
shown.
– Swivel the glide arm to the right stop (45°) by the handle
(1).
Checking (see figure W1)
– Set an angle gauge to 135° and place it on the saw table
(41).
The leg of the angle gauge must be flush with the saw blade
(43) along its entire length.
Setting (see figure W2)
– Tighten or loosen the set screw (72) using an open-ended
spanner (8 mm) until the leg of the angle gauge is flush
with the saw blade along its entire length.
– Retighten the clamping handle (14).
If the angle indicators (36) and (21) are not in line with the
45° marks on the scale (35) following adjustment, first
check the 0° setting for the bevel angle and the angle indicat-
ors once more. Then repeat the adjustment of the 45° bevel
angle.
Aligning the scale for mitre angles
– Bring the power tool into the work position.
– Turn the saw table (41) to the 0° detent (15). The lever
(13) must be felt to engage in the detent.
Checking (see figure X1)
– Set an angle gauge to 90° and position it between the
fence (7) and the saw blade (43) on the saw table (41).
