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 machine into the transport position.
– Turn the saw table 16 to the 0° detent 15. The lever 13
must be felt to engage in the detent.
Checking: (see figure S1)
– Set an angle gauge to 90° and place it on the saw table 16.
The leg of the angle gauge must be flush with the saw blade 7
over the complete length.
Adjusting: (see figure S2)
– Loosen the lock lever 14.
– Loosen set screws 64 and 65 with the supplied open-end
spanner 42 (10 mm).
– Loosen set screw 63 (approx. 3 turns) with the supplied
hex key 33 (4 mm).
– Screw set screw 60 (10 mm) in or out until the leg of the
angle gauge is flush with the saw blade over the complete
length.

– Retighten the lock lever 14 again.
Afterwards, tighten set screw 63 first, and then set screws
64 and 65.
When the angle indicators 31 and 22 are not in line with the
0° marks of scale 30 after adjusting, loosen the fastening
screws of the angle indicators with the supplied cross-head
screwdriver 33 and align the angle indicators alongside the 0°
marks.
Setting the Standard 45° Bevel Angle (Leftward)
– Bring the power tool into the working position.
– Turn the saw table 16 to the 0° detent 15. The lever 13
must be felt to engage in the detent.
– Pull the left fence extension 19 completely outward.
– Loosen the lock lever 14 and tilt the tool arm leftward to
the stop (45°) by the handle 5.
Checking: (see figure T1)
– Set an angle gauge to 45° and place it on the saw table 16.
The leg of the angle gauge must be flush with the saw blade 7
over the complete length.
Adjusting: (see figure T2)
– Screw set screw 64 (10 mm) in or out until the leg of the
angle gauge is flush with the saw blade over the complete
length.
– Retighten the lock lever 14 again.
When the angle indicators 31 and 22 are not in line with the
45° marks of scale 30 after adjusting, firstly once more check
the 0° setting for the bevel angle and the angle indicators.
Then repeat the adjustment of the 45° bevel angle.
