Adjusting the laser
Note: To test the laser function, the power tool must be con-
nected to the power supply.
While adjusting the laser (e.g. when moving the tool
u
arm), never activate the on/off switch. Starting the
power tool accidentally can lead to injuries.
– Bring the power tool into the work position.
– Turn the saw table (10) to the 0° detent (45). The lever
(12) must be felt to engage in the detent.
To ensure precise cuts, the laser beams must be checked
and adjusted as necessary after intensive use.
Experience and suitable special tools are required for this.
A Bosch after-sales service point will handle this work
quickly and reliably.
Checking (see figure O1)
– Draw a straight cutting line on the workpiece.
– Slowly guide the tool arm downwards using the handle
(4).
– Position the workpiece so that the teeth of the saw blade
line up with the cutting line.
– Hold the workpiece in this position and slowly guide the
tool arm back up.
– Clamp the workpiece.
– Turn on the laser beam using the switch (19) without
pressing the lock-off button (5).
The laser beam must be flush with the cutting line on the
workpiece along its entire length, even if the tool arm is
guided downwards.
Setting (see figure O2)
– Turn the set screw (47) with a suitable screwdriver until
the laser beam is parallel to the entire length of the cut-
ting line on the workpiece.
One rotation anticlockwise moves the laser beam from left to
right; one rotation clockwise moves the laser beam from
right to left.
Checking and Adjusting the Basic Settings
To ensure precise cuts, the basic settings of the power tool
must be checked and adjusted as necessary after intensive
use.
Experience and suitable special tools are required for this.
A Bosch after-sales service point will handle this work
quickly and reliably.
Aligning the fence
– Bring the power tool into the transport position.
– Turn the saw table (10) to the 0° detent (45). The
lever (12) must be felt to engage in the detent.
– Fold out the folding fence (16).
Checking (see figure P1)
– Position the set square (48) with the 90° angle flush with
the saw blade (39) between the fence (8) and the saw
blade on the saw table (10).
The leg of the set square must be flush with the fence along
its entire length.
1 609 92A 8KE | (09.05.2023)
Setting (see figure P2)
– Loosen all hex socket screws (49) with the hex key (28)
provided.
– Rotate the fence (8) until the set square is flush along its
entire length.
– Retighten the screws.
Setting the Standard 0° Bevel Angle
– Bring the power tool into the transport position.
– Turn the saw table (10) to the 0° detent (45). The lever
(12) must be felt to engage in the detent.
Checking (see figure Q1)
– Position the set square (48) with the 90° angle flush with
the saw blade (39) between the saw table (10) and the
saw blade on the saw table (10).
The leg of the set square must be flush with the saw blade
(39) along its entire length.
Setting (see figure Q2)
– Loosen the clamping bolt (24).
– Loosen the lock nut of the stop screw (50) using a com-
mercially available box-ended or open-ended spanner.
– Turn the stop screw as far in or out as needed until the leg
of the set square is flush with the saw blade along its en-
tire length.
– Retighten the clamping bolt (24).
– Then re-tighten the lock nut of the stop screw (50).
If the angle indicator (30) is not aligned with the 0° mark on
the scale (31) following adjustment, loosen the screw (52)
using a commercially available cross-headed screwdriver
and align the angle indicator along the 0° mark. (See figure
S)
Setting the standard 45° bevel angle
– Bring the power tool into the work position.
– Turn the saw table (10) to the 0° detent (45). The
lever (12) must be felt to engage in the detent.
– Loosen the clamping bolt (24) and use the handle (4) to
swivel the tool arm all the way to the left (45°).
Checking (see figure R1)
– Position the set square (48) with the 45° angle flush with
the saw blade (39) between the saw table (10) and the
saw blade on the saw table (10).
The leg of the set square must be flush with the saw blade
(39) along its entire length.
Setting (see figure R2)
– Loosen the lock nut of the stop screw (51) using a com-
mercially available box-ended or open-ended spanner.
– Turn the stop screw as far in or out as needed until the leg
of the set square is flush with the saw blade along its en-
tire length.
– Retighten the clamping bolt (24).
– Then re-tighten the lock nut of the stop screw (51).
If the angle indicator (30) is not aligned with the 45° mark on
the scale (31) following adjustment, first check the 0° set-
ting for the bevel angle and the angle indicator once more.
Then repeat the adjustment of the 45° bevel angle.
