sions.
– Pull the tool arm away from the fences 6 and 21 until the
saw blade is in front of the workpiece.
– Switch on the machine.
– Press locking switch 17 and slowly guide the tool arm

Special Workpieces
When sawing curved or round workpieces, these must be es-
pecially secured against slipping. At the cutting line, no gap
may exist between workpiece, fence and saw table.
Provide for special fixtures, if required.
Checking and Adjusting the Basic Adjustment
 Before any work on the machine itself, pull the mains
plug.
To ensure precise cuts, the basic adjustment of the machine
must be checked and adjusted as necessary after intensive
use.
A certain level of experience and appropriate specialty tools
are required for this.
A Bosch after-sales service station will handle this mainte-
nance task quickly and reliably.
Setting the Standard Bevel Angle 0° (Vertical)
– Bring the power tool into the working position.
– Turn the saw table 22 to the 0° detent 28. The lever 26
must be felt to engage in the detent.
Checking: (see figure N1)
– Adjust an angle gauge to 90° and position it on the saw ta-
ble 22.
The leg of the angle gauge must be flush with the saw blade 39
over the complete length.
Adjusting: (see figure N2)
– Loosen the lock lever 10.
– Loosen the lock nut of the stop screw 33 using a commer-
cial box-end or open-end spanner (size 10 mm).
Bosch Power Tools
– Screw the stop screw in or out until the leg of the angle
gauge is flush with the saw blade over the complete length.
– Retighten the lock lever 10 again.
– Afterwards, retighten the lock nut of the stop screw 33
again.
In case the angle indicator 32 is not in a line with the 0° mark
of the scale 31 after the adjustment, loosen the screw 44 us-
ing a commercial cross-head screwdriver and align the angle
indicator along the 0° mark.
Setting the Standard Bevel Angle 45° (Vertical)
– Bring the power tool into the working position.
– Turn the saw table 22 to the 0° detent 28. The lever 26
must be felt to engage in the detent.
– Loosen the lock lever 10 and tilt the tool arm leftward to
the stop (45°) by the handle 16.
Checking: (see figure O1)
– 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 39
over the complete length.
Adjusting: (see figure O2)
– Loosen the lock lever 10.
– Loosen the lock nut of the stop screw 9 using a commercial
box-end or open-end spanner (size 10 mm).
– Screw the stop screw in or out until the leg of the angle
gauge is flush with the saw blade over the complete length.
– Retighten the lock lever 10 again.
– Afterwards, retighten the lock nut of the stop screw 9
again.
In case the angle indicator 32 is not in a line with the 45° mark
of the scale 31, firstly check the 0° setting for the bevel angle
and the angle indicator again. Then repeat the adjustment of
the 45° bevel angle.
Aligning the Angle Indicator (Horizontally) (see figure P)
– Bring the power tool into the working position.
– Turn the saw table 22 to the 0° detent 28. The lever 26
must be felt to engage in the detent.
Checking:
The angle indicator 24 must be in alignment with the 0° mark
of the scale 5.
Adjusting:
– Loosen screw 45 using a cross-head screwdriver and align
the angle indicator alongside the 0° mark.
– Retighten the screw again.
Transport (see figure Q)
Before transporting the power tool, the following steps must
be carried out:
– Loosen the locking screw 11 if tightened. Pull the tool arm
completely to the front and tighten the locking screw
again.
– Bring the machine into the transport position.
– Remove all accessories that cannot be mounted firmly to
the power tool.
If possible, place unused saw blades in an enclosed con-
tainer for transport.
