If required, clean all the parts to be fitted before installing
them.
– Swivel the retracting blade guard (11) backwards. Hold
the retracting blade guard in this position.

Transport Safety Lock (see figure D)
The transport safety lock (37) makes it easier to handle the
power tool when transporting it to various working locations.
Unlocking the power tool (work position)
– Press the tool arm down slightly by the handle (9) to re-
lease the transport safety lock (37).
– Pull the transport safety lock (37) all the way out.
– Slowly guide the tool arm upwards.
When sawing mitre and/or bevel angles, you have to pull the left-hand or right-hand adjustable fence (15) outwards depending
on the cutting direction, or remove it completely.

Clamping the Workpiece (see figure G)
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 (15)
and (14).
– Insert the supplied screw clamp (28) into one of the cor-
responding holes (35).
– Adjust the threaded rod (52) of the screw clamp to the
workpiece height.
– Tighten the threaded rod (52) to fix the workpiece in
place.

Locking the power tool (transport position)
– Loosen the locking screw (33) if it is clamping the slide
device (1) in place. Pull the tool arm fully forward and
tighten the locking screw again to lock the slide device.
– Screw the adjusting screw (4) all the way upwards.
– To lock the saw table (16) in place, tighten the locking
knob (21).
– Swing the tool arm downwards by the handle (9) until you
can press the transport safety lock (37) completely in-
wards.
The tool arm is now securely locked and ready for transport-
ation.

Preparing for operation

Extending the saw table (see figure E)
The free end of long workpieces must have something
placed underneath it or be supported.
The saw table can be extended left and right using the saw
table extensions (13).
– Pull the clamping lever (17) upwards.
– Pull out the saw table extension (13) to the required
length.
– To lock the saw table extension, push the clamping lever
(17) back down.
Moving the Fence (see figure F)
– Loosen the locking screw (51).
– Pull the left-hand adjustable fence (15) all the way out.
– Loosen the locking screw (51).
– Pull the left-hand adjustable fence (15) all the way out.
– Lift the adjustable fence upwards and out of the way.
– Remove the locking screw (51).
– Loosen the locking screw (51).
– Pull the right-hand adjustable fence (15) all the way out.
– Lift the adjustable fence upwards and out of the way.

Setting mitre and bevel angles

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.
Always tighten the locking knob (21) and the clamp-
u
ing lever (41) firmly before sawing. Otherwise the saw
blade can become wedged in the workpiece.
Note for adjusting mitre angles > 45°:
Before adjusting the mitre angle, pull the saw table
