– Push the locking switch (17) and swivel the retracting
blade guard (19) back as far as it will go.
– Hold the retracting blade guard in this position and re-
move the saw blade (39).
– Slowly push the retracting blade guard back down.
Fitting the saw blade
When fitting the saw blade, make sure that the cutting
u
direction of the teeth (arrow direction on the saw
blade) matches the direction of the arrow on the pro-
tective guard.
If required, clean all the parts you want to fit before installing
them.
– Push the locking switch (17), swivel the retracting blade
guard (19) back as far as it will go and hold it in this posi-
tion.
– Place the new saw blade on the inner clamping
flange (38).
– Slowly push the retracting blade guard back down.
– Place on the clamping flange (37) and the screw (36).
Press the spindle lock (29) until it engages and tighten
the screw by turning it anticlockwise.
Operation
Pull the plug out of the socket before carrying out any
u
work on the power tool.
Transport Safety Lock (see figure D)
The transport safety lock (30) 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 (16) to re-
lease the transport safety lock (30).
– Pull the transport safety lock (30) all the way out.
– Slowly guide the tool arm upwards.
Locking the power tool (transport position)
– Loosen the locking screw (11) if it is clamping the slide
device (12) in place. Pull the tool arm fully forward and
tighten the locking screw again to lock the slide device.
– To lock the saw table (22) in place, tighten the locking
knob (25).
– Push the locking switch (17) and slowly guide the tool
arm downwards using the handle (16).
– Guide the tool arm downwards until you can press the
transport safety lock (30) all the way in.
The tool arm is now securely locked and ready for transport-
ation.

Preparing for operation

Moving the fence (see figure E)
You have to move the adjustable fence (6) to saw bevel
angles.

– Loosen the locking screw (40) using the hex key (35)
provided.
Both external fastening screws must not be loosened.
– Pull the adjustable fence (6) all the way out.
– Re-tighten the locking screw (40).
After sawing the bevel angles, slide the adjustable fence (6)
back again (loosen the locking screw (40); slide the fence
(6) completely inward; retighten the locking screw).
Extending the saw table (see figure F)
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 (3).
– Loosen the clamping screw (2).
– Pull out the saw table extension (3) to the required
length.
– Retighten the clamping screw (2) to fix the saw table ex-
tension.
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 (6)
and (21).
– Insert the supplied screw clamp (7) into one of the cor-
responding holes (41).
– Adjust the threaded rod (42) of the screw clamp to the
workpiece height.
– Tighten the threaded rod (42) to fix the workpiece in
place.
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 (25) firmly before
u
sawing. Otherwise the saw blade can become wedged in
the workpiece.
Setting mitre angles (see figure H)
The mitre angle can be set between 47° (left side) and 47°
(right side).
– Loosen the locking knob (25) if it is tightened.
– Push the lever (26), turn the saw table (22) left or right
by the locking knob and set the required mitre angle using
the angle indicator (24).
– Retighten the locking knob (25).
For quick and precise setting of commonly used mitre
angles, detents (28) are provided on the saw table:
Left
0°
Right
