Practical advice
General sawing instructions
Before making any cuts, first make sure that the saw
u
blade cannot come into contact with the stops or any
other parts of the tool at any time.
Only use the power tool for grooving or routing if a
u
suitable protective guard (e.g. tunnel blade guard,
featherboard) is in place.
Do not use the power tool for cutting slots (stopped
u
grooves).
Protect the saw blade against impact and shock. Do not sub-
ject the saw blade to lateral pressure.
The riving knife must be aligned with the saw blade in order
to prevent the workpiece from jamming.
Do not saw workpieces that have become bent or twisted
out of shape. The workpiece must always have a straight
edge to face against the parallel guide.
Always store the push stick on the power tool.
Position of the operator (see figure G)
Never stand directly in line with the saw blade. Always
u
position your body on the same side of the saw blade
as the fence. Kickback may propel the workpiece at high
velocity towards anyone standing in front and in line with
the saw blade.
– Keep hands, fingers and arms away from the rotating saw
blade.
Pay attention to the following instructions:
– Hold the workpiece firmly with both hands and press it
securely against the saw table.
– When using narrow workpieces or sawing bevel angles, al-
ways use the push stick (15) and the additional parallel
guide (47) provided.

Sawing
Making straight cuts
– Adjust the parallel guide (9) to the desired cutting width.
– Place the workpiece on the saw table in front of the pro-
tective cover (6).
– Use the crank (17) to raise or lower the saw blade as far
up or down as needed to position the top teeth of the saw
blade (28) approx. 3−6 mm above the workpiece.
– Switch on the power tool.
– Saw through the workpiece applying uniform feed.
If you apply too much pressure, the tip of the saw blade
could overheat and damage the workpiece.
– Switch off the power tool and wait until the saw blade has
come to a complete stop.

Sawing a bevel angle
– Set the required saw blade bevel angle.
If the saw blade is tilted to the left, the parallel guide (9)
must be to the right of the blade.
– Follow the work steps set out in the (see "Making straight
cuts", page 35) section
Sawing mitre angles (see figure H)
– Set the required mitre angle on the angle guide (3).
– Place the workpiece on the profile rail (50).
The profile must not be positioned along the cut line. If it
is, loosen the wing nut (51) and reposition the profile rail.
– Use the crank (17) to raise or lower the saw blade as far
up or down as needed to position the top teeth of the saw
blade (28) approx. 3–6 mm above the workpiece.
– Switch on the power tool.
– Hold the workpiece against the profile rail (50) with one
hand; place your other hand on the locking knob (60) and
slide the angle guide slowly forwards in the guide
groove (3).
– Switch off the power tool and wait until the saw blade has
come to a complete stop.
Checking and adjusting the basic settings
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.
Adjusting the stops for a standard bevel angle 0°/45°
– Bring the power tool into the work position.
– Set the saw blade to a bevel angle of 0°.
Checking (see figure I1)
– Set an angle gauge to 90° and place it on the saw table
(4).
The leg of the angle gauge must be flush with the saw blade
(28) along its entire length.
Setting (see figure I2)
– Loosen the screw (64). This enables the 0° stop (24) to
be moved.
– Loosen the locking lever (16).
– Slide the hand wheel (18) towards the 0° stop until the
leg of the angle gauge is flush with the saw blade along its
entire length.
– Hold the hand wheel in this position and retighten the
locking lever (16).
– Retighten the screw (64).
If the angle indicator (59) is not aligned with the 0° mark on
the scale (23) following adjustment, loosen the screw (65)
using a conventional cross-headed screwdriver and align the
angle indicator along the 0° mark.
Repeat the work step above for the bevel angle of 45°
(loosen the screw (66); move the 45° stop (22)). The angle
indicator (59) must not be repositioned when doing this.
