Checking and Adjusting the Basic
Adjustment
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 maintenance task quickly and reliably.
Aligning the Angle Indicator (Horizontally)
(see figure O)
Bring the power tool into the working posi-
tion.
Turn the saw table 7 to the 0° detent 14. The
lever 12 must be felt to engage in the detent.
Checking:
The angle indicator 13 must be in alignment
with the 0° mark of the scale 8.
Adjusting:
Loosen the screw 44 with the Phillips screw-
driver provided and align the angle indicator
along the 0° mark.
Retighten the screw again.
Aligning the Angle Indicator (Vertically)
(see figure P)
Bring the power tool into the working posi-
tion.
Turn the saw table 7 to the 0° detent 14. The
lever 12 must be felt to engage in the detent.
Checking:
The angle indicator 20 must be in alignment
with the 0° mark of the scale 19.
Adjusting:
Loosen the screw 45 with the Phillips screw-
driver provided and align the angle indicator
along the 0° mark.
Afterwards, check to ensure that the adjust-
ment made is correct for the 45° mark.
Retighten the screw again.
Aligning the Fence
Bring the machine into the transport posi-
tion.
Turn the saw table 7 to the 0° detent 14. The
lever 12 must be felt to engage in the detent.
Checking: (see figure Q1)
Set an angle gauge to 90° and place it on the
saw table 7 between the fence 18 and the
saw blade 37.
The leg of the angle gauge must be flush with
the fence over the complete length.
Adjusting: (see figure Q2)
Loosen all Allen screws 24 with the Allen key
provided.
Turn the fence 18 until the angle gauge is
flush over the complete length.
Retighten the screws again.
Setting the Standard Bevel Angle 0°
(Vertical)
Bring the machine into the transport posi-
tion.
Turn the saw table 7 to the 0° detent 14
. The
lever 12 must be felt to engage in the detent.
Checking: (see figure R1)
Set an angle gauge to 90° and place it on the
saw table 7.
The leg of the angle gauge must be flush with
the saw blade 37 over the complete length.
Adjusting: (see figure R2)
–Turn the Allen screw 46 in or out using a suit-
able Allen key (size 3 mm) until the leg of the
angle gauge is flush with the saw blade over
its complete length.
In case the angle indicator 20 is not in a line with
the 0° mark of the scale 19 after the adjust-
ment, the angle indicator must be aligned ac-
cordingly (see “Aligning the Angle Indicator
(Vertically)”, page 23).
