Adjusting the Laser
Note: To test the laser function, the machine must be con-
nected to power.
 While adjusting the laser (e. g. when moving the tool
arm), never actuate the On/Off switch. Accidental start-
ing of the power tool can lead to injuries.
– Bring the power tool into the working position.
– Turn the saw table 15 to the 0° detent 24. The lever 21
must be felt to engage in the detent.
– Switch the laser beam on with switch 39.
Checking: (see figure S1)
– Draw a straight cutting line on the workpiece.
– Press locking switch 9 and slowly guide the tool arm down-
ward by the handle 8.
– Align the workpiece in such a manner that the teeth of the
saw blade are in alignment with the cutting line.
– Hold the workpiece in this position and slowly guide the
tool arm upward again.
– Clamp the workpiece.
The laser beam must be in alignment with the cutting line on
the workpiece over the complete length, also when the tool
arm is lowered.
Adjusting: (see figure S2)
– Screw the adjustment screw 52 in or out using a suitable
screwdriver until the laser beam is parallel with the cutting
line on the workpiece over the complete length.
One rotation in anticlockwise direction moves the laser beam
from left to right; one rotation in clockwise direction moves
the laser beam from right to left.
Setting the Standard Bevel Angle 0° (Vertical)
– Bring the power tool into the working position.
– Turn the saw table 15 to the 0° detent 24. The lever 21
must be felt to engage in the detent.
Checking: (see figure T1)
– Adjust an angle gauge to 90° and position it on the saw ta-
ble 15.
The leg of the angle gauge must be flush with the saw blade 12
over the complete length.
Adjusting: (see figure T2)
– Loosen clamping lever 40.
– Push the stop 43 completely to the rear.
– Loosen the lock nut of the stop screw 53 using a commer-
cial 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.
– Tighten clamping lever 40 again.
– Afterwards, retighten the lock nut of the stop screw 53
again.
In case the angle indicator 42 is not in a line with the 0° mark
of the scale 41 after the adjustment, loosen the screw 54 us-
ing a commercial Phillips screwdriver and align the angle indi-
cator along the 0° mark.
Bosch Power Tools
Setting the Standard Bevel Angle 45° (Vertical)
– Bring the power tool into the working position.
– Turn the saw table 15 to the 0° detent 24. The lever 21
must be felt to engage in the detent.
– Turn the stop 30 completely to the front.
– Loosen clamping lever 40 and tilt the tool arm by handle 8
leftward to the stop (45°).
Checking: (see figure U1)
– Adjust an angle gauge to 45° and position it on the saw ta-
ble 15.
The leg of the angle gauge must be flush with the saw blade 12
over the complete length.
Adjusting: (see figure U2)
– Loosen the lock nut of the stop screw 55 using a commer-
cial 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.
– Tighten clamping lever 40 again.
– Afterwards, retighten the lock nut of the stop screw 55
again.
In case the angle indicator 42 is not in a line with the 45° mark
of the scale 41, 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 V)
– Bring the power tool into the working position.
– Turn the saw table 15 to the 0° detent 24. The lever 21
must be felt to engage in the detent.
Checking:
The angle indicator 23 must be in alignment with the 0° mark
of the scale 17.
Adjusting:
– Loosen screw 56 using a Phillips screwdriver and align the
angle indicator alongside the 0° mark.
– Retighten the screw again.
Transport (see figure X)
Before transporting the power tool, the following steps must
be carried out:
– Loosen the locking screw 33 if tightened. Pull the tool arm
completely to the front and tighten the locking screw
again.
– Make sure that the depth stop 32 is pushed completely in-
ward and that adjusting screw 4 fits through the recess
without touching the depth stop when moving the tool
arm.
– 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.
– Wind up the mains cable and tie it together with Velcro
strap 58.
– Carry the machine by the transport handle 3 or hold it by
the recessed handles 26 on the sides of the saw table.
