– Switch off the power tool and wait until the saw blade has
come to a complete stop.
– Slowly guide the glide arm (23) upwards.
Adjusting the Depth Stop (Sawing the Groove) (see
figure Q)
The depth stop needs to be adjusted if you wish to saw a
groove or use a spacer.
– Swivel the depth stop
(25) outwards.
– Use the handle (3) to swivel the glide arm (23) into the
required position.
– Turn the adjusting screw (24) until the end of the screw
touches the depth stop (25) .
– Slowly guide the glide arm (23) upwards.
Special workpieces
When sawing curved or round workpieces, these must be es-
pecially secured against slipping. At the cutting line, there
should be no gap between the workpiece, fence and saw
table.
If necessary, you will need to manufacture special fixtures.
Working on mouldings
Mouldings can be sawn in two different ways:
Positioning of
workpiece Base moulding Crown moulding
– Placed against
the fence
– Lying flat on the
saw table
Furthermore, you can cut with or without the slide move-
ment depending on the width of the moulding.
Always check the set mitre and/or bevel angle first by mak-
ing trial cuts in scrap wood.
Checking and Adjusting the Basic Settings
To ensure precise cuts, the basic settings of the power tool
must be checked and adjusted as necessary after intensive
use.
Experience and suitable special tools are required for this.
A Bosch after-sales service point will handle this work
quickly and reliably.
Setting the Standard 0° Bevel Angle
– Bring the power tool into the transport position.
– Turn the saw table
(33) to the 0° detent (14) . The lever
(12) must be felt to engage in the detent.
Checking (see figure R1)
– Set an angle gauge to 90° and place it on the saw table
(33) .
The leg of the angle gauge must be flush with the saw blade
(34) along its entire length.
Setting (see figure R2)
– Loosen the clamping handle (13) .
– Loosen the two set screws (54) (by at least one turn) us-
ing a socket spanner (10 mm).
– Loosen the set screw (56) (by approx. three turns) using
the hex key (4 mm) (30) .
– Tighten or loosen the set screw (55) using the hex key (4
mm) (30) until the leg of the angle gauge is flush with the
saw blade along its entire length.
– Retighten the clamping handle (13) . Then tighten the set
screw (56) followed by the set screws (54) .
If the angle indicators (28) and (21) are not in line with the
0° marks on the scale (27) 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.
– Turn the saw table
(33) to the 0° detent (14) . The lever
(12) must be felt to engage in the detent.
– Pull the left-hand adjustable fence (7) all the way out.
– Loosen the clamping handle (13) and swivel the glide arm
to the left stop (45°) by the handle (3) .
Checking (see figure S1)
– Set an angle gauge to 45° and place it on the saw table
(33) .
The leg of the angle gauge must be flush with the saw blade
(34) along its entire length.
Setting (see figure S2)
– Tighten or loosen the set screw (57) using a ratchet span-
ner (8 mm) until the leg of the angle gauge is flush with
the saw blade along its entire length.
– Retighten the clamping handle (13) .
If the angle indicators (28) and (21) are not in line with the
45° marks on the scale (27) 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
(33) to the 0° detent (14) . The lever
(12) must be felt to engage in the detent.
– Pull the right-hand adjustable fence (7) all the way out.
– Loosen the clamping handle (13) .
– Use the handle (3) to tilt the glide arm slightly to
the left from the 0° position and turn the rotary
knob
(32) until the right-hand bevel angle range is
shown.
– Swivel the glide arm to the right stop (45°) by the handle
(3) .
Checking (see figure T1)
– Set an angle gauge to 135° and place it on the saw table
(33) .
