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.
– Slowly push the retracting blade guard back down.
– Fit the clamping flange (45) and the hex socket screw
(44). Press the spindle lock (33) until it engages and
tighten the screw by turning it anticlockwise.
Assembly with SDS bolt (see figure G)
Removing the saw blade:
– Bring the power tool into the work position.
– Press and hold the spindle lock (33) and unscrew the
SDS bolt (48) by turning it clockwise (left-hand thread).
– Remove the clamping flange (45).
– Swivel the retracting blade guard (11) backwards as far
as possible.
– Hold the retracting blade guard in this position and re-
move the saw blade (46).
– Slowly push the retracting blade guard back down.
Fitting the saw blade:
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.
– Place the new saw blade onto the interior clamping flange
(47).
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.
– Slowly push the retracting blade guard back down.
– Attach the clamping flange (45) and the SDS bolt (48).
Press the spindle lock (33) until it engages and tighten
the SDS bolt by turning it anticlockwise.
Operation
Remove the battery from the power tool before carry-
u
ing out work on the power tool (e.g. maintenance,
changing tool, etc.). The battery should also be re-
moved for transport and storage. There is risk of injury
from unintentionally pressing the on/off switch.

Transport safety lock (see figure H)

The transport safety lock (36) 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 (36).
– Pull the transport safety lock (36) all the way out.
– Slowly guide the tool arm upwards.
Bosch Power Tools
Locking the power tool (transport position)
– Loosen the locking screw (32) 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 (5) all the way upwards.
– To lock the saw table (17) in place, tighten the locking
knob (19).
– Swing the tool arm downwards by the handle (9) until you
can press the transport safety lock (36) completely in-
wards.
The tool arm is now securely locked and ready for transport-
ation.

Preparing for operation

Extending the saw table (see figure I)
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 (14).
– Loosen the clamping screw (15).
– Pull out the saw table extension (14) to the required
length.
– Retighten the clamping screw (15) to fix the saw table ex-
tension.
Moving the fence (see figure J)
You have to move the adjustable fence (25) to saw bevel
angles.
– Loosen the locking screw (49).
– Pull the adjustable fence (25) all the way out.
– Re-tighten the locking screw (49).
After sawing the bevel angles, slide the adjustable fence
(25) back again (loosen the locking screw (49); slide the
fence (25) completely inward; retighten the locking screw).
Clamping the workpiece (see figure K)
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 (13) and
(25).
– Insert the supplied screw clamp (26) into one of the holes
(51) intended for this purpose.
– Adjust the threaded rod (50) of the screw clamp to the
workpiece height.
– Tighten the threaded rod (50) 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 (see "Checking and adjusting the basic settings").
Always tighten the locking knob (19) firmly before
u
sawing. Otherwise the saw blade can become wedged in
the workpiece.
