– Hold the spindle lock 44 pressed and unscrew the hex
socket screw 45 in clockwise direction (left-hand thread!).
– Remove the clamping flange 46.
– Press button 4 and tilt back the retracting blade guard 7 to
the stop.
– Hold the retracting blade guard in this position and remove
the saw blade 8.
– Slowly guide the retracting blade guard downward again.
Mounting the Saw Blade
If required, clean all parts to be mounted prior to assembly.
– Press button 4, tilt back the retracting blade guard 7 to the
stop and hold it in this position.
– Place the new saw blade onto the interior clamping flange
47.
 When mounting the saw blade, pay attention that the
cutting direction of the teeth (arrow direction on the
saw blade) corresponds with the direction of the arrow
on the blade guard!
– Slowly guide the retracting blade guard downward again.
– Place on the clamping flange 46 and the screw 45.
Press the spindle lock 44 until it engages and tighten the
screw turning in anticlockwise direction.
– For working afterwards, the tool arm must be released
again. For this, loosen the transport-safety lock 35 by pull-
ing it outward and turning by 90°.
Operation
 Before any work on the machine itself, pull the mains
plug.
Transport Safety (see figure H)
The transport safety-lock 35 enables easier handling of the
machine when transporting to various working locations.
Releasing the Machine (Working Position)
– Push the tool arm by the handle 5 down a little in order to
relieve the transport safety-lock 35.
– Pull the transport safety-lock 35 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 32 if tightened. Pull the tool arm
completely to the front and tighten the locking screw
again.
– Screw the depth stop 30 completely to the top. (see "Ad-
justing the Depth Stop", page 35)
– To lock the saw table 17, tighten the locking knob 13.
– Press button 4 and tilt down the tool arm by the handle 5.
– Pull the transport safety-lock 35 all the way outward and
turn it by 90°. Allow the transport safety-lock to engage in
this position.
– The tool arm is now securely locked for transport.
Bosch Power Tools
Extending the Saw Table (see figure I)
Long workpieces must be underlaid or supported at their free
end.
– Loosen the wing nut 48 and pull the saw table extension 39
on the extension bar outward to the distance required.
– Tighten the wing nut again.
Clamping the Workpiece
To ensure optimum working safety, the workpiece must al-
ways be firmly clamped.
Do not saw workpieces that are too small to clamp.
Vertical Clamping (see figure J1)
– Insert the quick-action clamp 49 provided into one of the
holes 11 intended for this purpose.
– Press the workpiece firmly against the fence 10.
– Press the quick-release button 50 and adapt the quick-ac-
tion clamp to the workpiece.
– Afterwards, turn the locking knob 51 in clockwise direc-
tion to clamp the workpiece.
Horizontal Clamping (see figure J2)
– Loosen wing nut 52 and pull the quick-action clamp apart.
– Insert the now "reduced" quick-action clamp 49 into one of
the holes 11 intended for this purpose.
– Press the workpiece firmly against the saw table 17.
– Press the quick-release button 50 and adapt the quick-ac-
tion clamp to the workpiece.
– Afterwards, turn the locking knob 51 in clockwise direc-
tion to clamp the workpiece.
Loosening the Workpiece
– To release the quick-action clamp, firstly turn the loosen-
ing knob 51 in anticlockwise direction.
– Now press on the quick-release button 50 and pull the
threaded rod away from the workpiece.
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 35).
 Always tighten the locking knob 13 firmly before saw-
ing. Otherwise the saw blade can become wedged in the
workpiece.
Adjusting Mitre Angles
The mitre angle can be set in the range from 47° (left side) to
53° (right side).
– Loosen the locking knob 13 in case it is tightened.
– Turn the saw table 17 left or right by the locking knob until
the angle indicator 14 indicates the requested mitre angle.
– Tighten the locking knob 13 again.
