Securing the Machine (Transport Position)
– Loosen the locking screw 31 if tightened.
Pull the tool arm completely to the front and
tighten the locking screw again.
– Screw the depth stop 58 completely to the
top. (see "Adjusting the Depth Stop",
page 46)
– To lock the saw table 18, tighten the locking
knob 14.
– Pull the transport safety-lock 28 all the way
outward and turn it by 90°. Allow the trans-
port safety-lock to engage in this position.
– Push the locking lever 43 and at the same
time lower the tool arm via handle 7 until the
transport safety-lock engages in the end po-
sition.
The tool arm is now securely locked for trans-
port.
Preparing for Operation
Extending the Saw Table (see figure F)
Long workpieces must be underlaid or support-
ed at their free end.
– Push tensioning lever 39 upward.
– Pull out saw-table extension 38 to the de-
sired length (max. 225 mm).
– Lock in place by pushing tensioning lever 39
down again.
Extending the Fence (see figure G)
For bevel angles, the fence extensions 21 must
be moved.
– Loosen locking screw 22 and completely pull
out the fence extension 21.
– Retighten the screw again.
Clamping the Workpiece (see figure H)
To ensure optimum working safety, the work-
piece must always be firmly clamped.
Do not saw workpieces that are too small to
clamp.
While clamping the workpiece, do not reach
under the clamping lever of the quick-ac-
tion clamp with your fingers.
– Press the workpiece firmly against the
fence 20.
Bosch Power Tools
– Insert the quick-action clamp 23 into one of
the holes 52 intended for this purpose.
– Adapt the quick-action clamp to the work-
piece by turning the threaded rod 54.
– Push on the clamping lever 53 in order to
clamp the workpiece.
Adjusting Horizontal Mitre Angles
To ensure precise cuts, the basic adjustment of
the machine must be checked and adjusted as
necessary after intensive use (see "Checking
and Adjusting the Basic Adjustment", page 49).
Always tighten the locking knob 14 firmly
before sawing. Otherwise the saw blade can
become wedged in the workpiece.
Adjusting Horizontal Standard Mitre Angles
(see figure I)
For quick and precise adjustment of commonly
used mitre angles, detents 17 have been provid-
ed for on the saw table:
Left
0°
15°; 22.5°; 15°; 22.5°;
31.6°; 45°; 52° 31.6°; 45°; 60°
– Loosen the locking knob 14 in case it is tight-
ened.
– Pull lever 15 and rotate the saw table 18 left
or right to the requested detent.
– Release the lever again. The lever must be
felt to engage in the detent.
Adjusting Any Horizontal Mitre Angle
(see figure J)
The horizontal mitre angle can be set in the
range from 52° (left side) to 60° (right side).
– Loosen the locking knob 14 in case it is tight-
ened.
– Pull lever 15 and at the same time push the
locking bracket 13 until it engages in the
groove intended for this. The saw table can
be moved freely now.
– Turn the saw table 18 left or right by the lock-
ing knob until the angle indicator 66 indi-
cates the requested mitre angle.
– Tighten the locking knob 14 again.
