Preparing for operation
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.
Extending/Expanding the Saw Table (see figures F−G)
The free end of long and heavy workpieces must have some-
thing placed underneath it or be supported.
The saw table can be extended left and right using the saw
table extensions (23).
– Loosen the clamping screw (22).
Moving the fence (see figure H)
When sawing mitre and/or bevel angles, you have to pull the left-hand or right-hand adjustable fence (26) outwards depending
on the cutting direction, or remove it completely.
Bevel angle Mitre angle
0°–22.5° > 0°

(left/right) (left/right)
Clamping the Workpiece (see figure I)
To ensure maximum safety while working, the workpiece
must always be firmly clamped.
Do not saw workpieces that are too small to clamp firmly.
– Press the workpiece firmly against the fences (26)
and (25).
– Insert the supplied screw clamp (41) into one of the cor-
responding holes (42).
– Adjust the threaded rod (40) of the screw clamp to the
workpiece height.
– Tighten the threaded rod (40) to fix the workpiece in
place.
Adjusting mitre angles
Setting Standard Mitre Angles (see figure J)
For quick and precise setting of commonly used mitre
angles, detents (20) are provided on the saw table:
Left
0°
45°; 30°; 22.5°; 15°
– Loosen the locking knob (16) if it is tightened.
– Pull the lever (17) and rotate the saw table (12) left or
right to the required detent.
– Release the lever again. The lever must be felt to engage
in the detent.
– Retighten the locking knob (16).

– Pull out the saw table extension (23) to the required
length.
– Retighten the clamping screw (22) to fix the saw table ex-
tension.
The flexible connector system of the workpiece
supports (24) enables a multitude of extension or expansion
variants.
– Insert the workpiece support (24) into the openings (47)
on the power tool or into the openings (48) of the second
workpiece support as required.
Never carry the power tool using the workpiece sup-
u
ports.
Only use the transport devices to transport the power
tool.
– Loosen the left-hand/right-hand locking screw (44).
– Pull the left-hand/right-hand adjustable fence (26) all the way out.
– Loosen the left-hand/right-hand locking screw (44).
– Pull the left-hand/right-hand adjustable fence (26) all the way out.
– Lift the adjustable fence upwards and out of the way.
Setting Any Mitre Angle (see figure K)
The mitre angle can be set between 48° (left-hand side) and
48° (right-hand side).
– Loosen the locking knob (16) if it is tightened.
– Pull the lever (17) and at the same time press the locking
clamp (15) until this clicks into the slot provided for it.
This means the saw table can now move freely.
– Turn the saw table (12) left or right by the locking knob
until the angle indicator (58) shows the required mitre
angle.
– Retighten the locking knob (16).
– To loosen the lever (17) again (for setting standard mitre
angles), pull the lever upwards.
The locking clamp (15) springs back into its original posi-
tion and the lever (17) can click back into the detents
(20).
Adjusting bevel angles
Right
The bevel angle can be set between 47° (left-hand side)
and 47° (right-hand side).
15°; 22.5°; 30°; 45°
For quick and precise setting of frequently used bevel
angles, fixed positions have been provided for the angles 0°,
22.5° and 45°.
– Make sure that the clamping wheel (45) is fitted (see "Fit-
ting the Clamping Wheel (see figure A2)", page 20).
Setting Standard Bevel Angles (see figure L)
– Pull the adjustable fences (26) all the way out or remove
them completely.
– Release the clamping wheel (45).
