Mounting the Saw Blade
If required, clean all parts to be mounted prior to assembly.
– Place the new saw blade onto the interior clamping flange
44.
 Take care during the mounting that the cutting direc-
tion of the teeth (direction of the arrow on the saw
blade) agrees with the direction of the arrow on the
retracting blade guard!
– Mount the clamping flange 43, the washer 42 and the hex-
agon bolt 41.
Press spindle lock 40 until it engages and tighten hexagon
bolt 41 with the provided ring spanner 35 (tightening
torque approx. 20 Nm).
– Push the locking lever 4 and guide the retracting blade
guard 8 down again.
– Retighten the screws 39 and 38.
Operation
 Before any work on the machine itself, pull the mains
plug.
Transport Safety (see figure E)
The transport safety-lock 33 enables easier handling of the
machine when transporting to various working locations.
Releasing the Machine (Working Position)
– Push the tool arm by the handle 6 down a little in order to
relieve the transport safety-lock 33.
– Pull the transport safety-lock 33 all the way outward and
turn it by 90°. Allow the transport safety-lock to engage in
this position.
– Guide the tool arm slowly upward.
Securing the Machine (Transport Position)
– Loosen the locking screw 26 if tightened. Pull the tool arm
completely to the front and tighten the locking screw
again.
– Screw the depth stop 51 completely to the top (see "Ad-
justing the Depth Stop", page 29).
– To lock the saw table 17, tighten the locking knob 13.
– Pull the transport safety-lock 33 all the way outward and
turn it by 90°. Allow the transport safety-lock to engage in
this position.
– Push the locking lever 4 and at the same time lower the tool
arm via handle 6 until the transport safety-lock engages in
the end position.
The tool arm is now securely locked for transport.

Preparing for Operation

Extending the Saw Table (see figure F)
Long workpieces must be underlaid or supported at their free
end.
– Loosen both hex socket screws 19 with the hex key 30
provided.
– Pull out the saw table extension 21 to the stop and tighten
the hex socket screws again.
Bosch Power Tools
Mounting the Extension Bars (see figure G)
To extend the saw table additionally, extension bars can be
mounted both to the left or right of the power tool.
– Mount one length stop 52 each onto an extension bar 45.
– Insert the extension bars 45 on both sides of the power
tool to the stop in the drill holes 20 intended for this pur-
pose.
– Tighten the screws for securing the extension bars.
Clamping the Workpiece (see figure H)
To ensure optimum working safety, the workpiece must al-
ways be firmly clamped.
Do not saw workpieces that are too small to clamp.
– Press the workpiece firmly against the fence 9.
– Insert the material clamp 22 provided into one of the holes
29 intended for it.
– Loosen the wing bolt 46 and adapt the material clamp to
the workpiece. Tighten the wing bolt again.
– Firmly clamp the workpiece by turning the threaded rod
47 in clockwise direction.

Adjusting the Cutting Angle

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 30).
 Always tighten the locking knob 13 firmly before saw-
ing. Otherwise the saw blade can become wedged in the
workpiece.
Adjusting Standard Mitre Angles (see figure I)
For quick and precise adjustment of commonly used mitre an-
gles, detents 16 have been provided for on the saw table:
Left
0°
45° 31.6° 22.5° 15° 15° 22.5° 31.6° 45° 60°
– Loosen the locking knob 13 in case it is tightened.
– Pull lever 14 and rotate the saw table 17 left or right to the
requested detent.
– Release the lever again. The lever must be felt to engage in
the detent.
Adjusting Any Mitre Angle (see figure J)
The mitre angle can be set in the range from 52° (left side) to
62° (right side).
– Loosen the locking knob 13 in case it is tightened.
– Pull lever 14 and at the same time push the locking bracket
12 until it engages in the groove intended for this. The saw
table can be moved freely now.
– Turn the saw table 17 left or right by the locking knob until
the angle indicator 15 indicates the requested mitre angle.
– Tighten the locking knob 13 again.
