– Swivel the retracting blade guard (12) to the back and
hold it in this position.
– Place the new saw blade on the inner clamping
flange (53).
– Fit the clamping flange (52) and the hex socket
screw (51). Press the spindle lock (33) until it engages
and tighten the hex socket screw by turning it anticlock-
wise.
– Slowly push the retracting blade guard back down.
Operation
Pull the plug out of the socket before carrying out any
u
work on the power tool.
Transport Safety Lock (see figure E)
The transport safety lock (34) 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 (34).
– Pull the transport safety lock (34) all the way out.
– Slowly guide the tool arm upwards.
Locking the power tool (transport position)
– Loosen the locking screw (1) if it is clamping the slide
device (2) in place. Pull the tool arm fully forward and
tighten the locking screw again to lock the slide device.
– Pull the depth stop (39) upwards.
– To lock the saw table (14) in place, tighten the locking
knob (18).
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 (28) outwards depending
on the cutting direction, or remove it completely.

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 (28)
and (27).
– 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.
Bosch Power Tools
– Swing the tool arm downwards by the handle (9) until you
can press the transport safety lock (34) all the way in.
The tool arm is now securely locked and ready for transport-
ation.
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 (25).
– Loosen the clamping screw (24).
– Pull out the saw table extension (25) to the required
length.
– Retighten the clamping screw (24) to fix the saw table ex-
tension.
The flexible connector system of the workpiece
supports (26) enables a multitude of extension or expansion
variants.
– Insert the workpiece support (26) 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 (28) all the way out.
– Loosen the left-hand/right-hand locking screw (44).
– Pull the left-hand/right-hand adjustable fence (28) all the way out.
– Lift the adjustable fence upwards and out of the way.
– Tighten the threaded rod (40) to fix the workpiece in
place.
