Adjusting: (see figure Q2)
– Loosen the nut (size 10 mm) of the Allen screw 55.
– Screw the Allen screw 55 with a suitable Allen wrench (size
3 mm) in or out until the leg of the angle gauge is flush with
the saw blade over the complete length.
– Retighten the nut again.
In case the angle indicator 45 is not in a line with the 0° mark
of the scale 46 after the adjustment, the angle indicator must
be aligned accordingly (see "Aligning the Angle Indicator (Ver-
tically)", page 46).
Setting the Standard Bevel Angle 45° (Vertical)
– Bring the power tool into the table saw working position.
(see "Working Position", page 47)
– Turn the saw table 22 to the 0° detent 27. The lever 26
must be felt to engage in the detent.
– Loosen the clamping lever 36 and tilt the tool arm leftward
to the stop (45°) by the handle 18.
Checking: (see figure R1)
– Adjust an angle gauge to 45° and position it on the saw ta-
ble 22.
The leg of the angle gauge must be flush with the saw blade 7
over the complete length.
Adjusting: (see figure R2)
– Loosen the nut (size 10 mm) of the Allen screw 56.
– Screw the Allen screw 56 with a suitable Allen wrench (size
3 mm) in or out until the leg of the angle gauge is flush with
the saw blade over the complete length.
– Retighten the nut again.
In case the angle indicator 45 is not in a line with the 45° mark
of the scale 46, firstly check the 0° setting for the bevel angle
and the angle indicator again. Then repeat the adjustment of
the 45° bevel angle.
Setting the Standard Bevel Angle 33.9° (Vertical)
– Bring the power tool into the table saw working position.
(see "Working Position", page 47)
– Turn the saw table 22 to the 0° detent 27. The lever 26
must be felt to engage in the detent.
– Loosen the lock lever 36.
– Push the stop bolt 32 completely inside and swivel the tool
arm until the bolt faces against the stop screw 31.
Checking: (see figure S1)
– Adjust an angle gauge to 33.9° and position it on the saw
table 22.
The leg of the angle gauge must be flush with the saw blade 7
over the complete length.
Adjusting: (see figure S2)
– Loosen the nut (size 10 mm) of the stop screw 31.
– Screw the stop screw with a suitable spanner (size 10 mm)
in or out until the leg of the angle gauge is flush with the saw
blade over the complete length.
– Retighten the nut again.
Bosch Power Tools
Operation as Table Saw
 Before any work on the machine itself, pull the mains
plug.
Working Position (see figure
If the power tool was used as a chop and mitre saw, then the
following steps must be carried out before using as a table
saw:
– Bring the power tool into the chop and mitre saw working
position. (see "Working Position", page 42)
– Pull the lower saw blade cover 64 out of the groove of the
parallel guide 59.
– Insert the lower saw blade cover 64 into the saw table 22.
– Set the vertical bevel angle to 0° and tighten the lock lever
36.
– Press release button 17 and slowly guide the tool arm by
handle 18 downward until the transport safety-lock 37 can
be pushed completely inward.
Preparing for Operation
Adjusting the Saw Blade Height (see figure
For safe operation, the correct working position of the saw
blade 7 to the workpiece must be adjusted. The maximum
workpiece height is 51 mm.
– Loosen both clamping levers 66 below the saw table 57.
– Tilt the protection guard 61 toward the rear to the stop and
position your workpiece next to the saw blade.
– Push the saw table down or pull it upward until the upper
saw teeth of the saw blade project approx. 1 mm above the
workpiece surface.
– Hold the saw table in this position and retighten the clamp-
ing levers again.
Adjusting the Parallel Guide (see figure
The parallel guide 59 can be positioned to the right of the saw
blade. The clearance indicator 67 indicates the clearance of
the parallel guide to the saw blade on the scale 63.
– Loosen the clamping knob 62.
This relieves the guide 69 at the rear of the parallel guide.
– Firstly, insert the parallel guide into the rear guide groove
of the saw table.
– Then position the parallel guide into the front guide groove
of the saw table.
The parallel guide can be moved variably now.
– Move the parallel guide until the clearance indicator 67 in-
dicates the requested clearance to the saw blade.
– To lock the parallel guide, push the clamping knob 62
downward again.
 Make sure that the parallel guide is always parallel to
the saw blade or that the sawblade/parallel guide clear-
ance increases toward the rear. Otherwise, danger is giv-
en that the workpiece is jammed between the saw blade
and the parallel guide.
