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 30 to the 0° detent 29. The lever 10
must be felt to engage in the detent.
Checking: (see figure S1)
– Adjust an angle gauge to 90° and position it on the saw ta-
ble 30.
The leg of the angle gauge must be flush with the saw blade 37
over the complete length.
Adjusting: (see figure S2)
– Loosen clamping lever 23.
– Push the stop 26 completely to the rear.
– Loosen the lock nut of the stop screw 59 using a commer-
cial box-end or open-end spanner (size 13 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 23 again.
– Afterwards, retighten the lock nut of the stop screw 59
again.
In case the angle indicator 25 is not in a line with the 0° mark
of the scale 24 after the adjustment, loosen the screw 58 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 30 to the 0° detent 29. The lever 10
must be felt to engage in the detent.
– Turn the stop 19 completely to the rear.
– Loosen clamping lever 23 and tilt the tool arm by handle 4
leftward to the stop (45°).
Checking: (see figure T1)
– Adjust an angle gauge to 45° and position it on the saw ta-

The leg of the angle gauge must be flush with the saw blade 37
over the complete length.
Adjusting: (see figure T2)
– Loosen the lock nut of the stop screw 60 using a commer-
cial box-end or open-end spanner (size 13 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 23 again.
– Afterwards, retighten the lock nut of the stop screw 60
again.
In case the angle indicator 25 is not in a line with the 45° mark
of the scale 24, 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 Scale for Mitre Angles
– Bring the power tool into the working position.
– Turn the saw table 30 to the 0° detent 29. The lever 10
must be felt to engage in the detent.
Checking: (see figure U1)
– Adjust an angle gauge to 90° and position it between the
fence 6 and the saw blade 37 on the saw table 30.
The leg of the angle gauge must be flush with the saw blade 37
over the complete length.
Adjusting: (see figure U2)
– Loosen all four set screws 61 with the hex key (4 mm) 17
and turn the saw table 30 together with the scale 13 until
the leg of the angle gauge is flush with the saw blade over
the complete length.
– Retighten the screws again.
When the angle indicator 12 is not in line with the 0° mark of
scale 13 after adjusting, loosen screw 62 with a cross-head
screwdriver and align the angle indicator alongside the
0° mark.
Transport (see figure V)
Before transporting the power tool, the following steps must
be carried out:
– Guide the tool arm downward until the transport safety-
lock 20 can be pushed completely inward.
– Slide the saw-table extensions 15 completely in and lock
them in place (by pushing clamping lever 14 down).
– Adjust a 0° bevel angle and tighten clamping lever 23.
– Turn saw table 30 rightward to the stop and tighten locking
knob 9.
– Wind up the mains cable and tie it together with Velcro
strap 63.
– 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.
– Carry the machine by the transport handle 45 or hold it by
the recessed handles 16 on the sides of the saw table.
 The power tool should always be carried by two per-
sons in order to avoid back injuries.
 When transporting the power tool, use only the trans-
port devices and never use the protective devices.

Maintenance and Service

Maintenance and Cleaning

If the replacement of the supply cord is necessary, this has to
be done by Bosch or an authorized Bosch service agent in or-
der to avoid a safety hazard.
Cleaning
For safe and proper working, always keep the power tool and
its ventilation slots clean.
The retracting blade guard must always be able to move freely
and retract automatically. Therefore, always keep the area
around the retracting blade guard clean.
