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 (14) to the 0° detent (22). The lever
(19) 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 T1)
– Draw a straight cutting line on the workpiece.
– Slowly guide the tool arm downwards using the
handle (9).
– 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.
– Switch on the laser beams with the switch (5).
The laser beams must be at the same distance from the
marked cutting line on the workpiece left and right along the
entire length, even if the tool arm is being guided down-
wards.
Removing the Laser Protection Cap (see figure T2)
– Unscrew the two screws (55) of the laser protection
cap (10) using a hex key/slotted screwdriver (43) and re-
move the laser protection cap.
Adjusting the Lateral Deviation when Moving the Tool
Arm (see figures T3−T4)
– Loosen the fastening screw (56) (by approx. one to two
turns).
Do not unscrew the screw completely.
– Move the laser housing (57) right or left until the laser
beams no longer laterally deviate when the tool arm
moves downwards.
– Hold the laser housing (57) in this position and retighten
the fastening screw (56).
– Reattach the laser protection cap (10).

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 mitre angle indicator (see figure U)
– Bring the power tool into the work position.
– Turn the saw table (14) to the 0° detent (22). The lever
(19) must be felt to engage in the detent.
Checking
The angle indicator(58) must be in line with the 0° mark of
the scale (23).
Setting
– Loosen the screw (59) using a cross-headed screwdriver
and align the angle indicator along the 0° mark.
– Retighten the screw.
Aligning the Angle Indicator (Vertical) (see figure V)
– Bring the power tool into the work position.
– Release the clamping wheel (45).
– Pull the locking lever (46) out and set the bevel angle to
0° with the tool arm.
– Let go of the locking lever (46). The locking lever must be
felt to engage in the position
– Retighten the clamping wheel (45).
Checking
The angle indicator(30) must be in line with the 0° mark of
the scale (29).
Setting
– Loosen the screw (60) using a cross-headed screwdriver
and align the angle indicator along the 0° mark.
– Retighten the screw.
Transporting the Power Tool (see figure W)
Before transporting the power tool, the following steps must
be carried out:
– Loosen the locking screw (1) if it is tightened. Pull the
tool arm fully forwards and retighten the locking screw.
– Ensure that the depth stop (39) is swung all the way back
and the adjusting screw (38) does not touch anything
when you move the tool arm.
– Bring the power tool into the transport position.
– Remove all accessories that cannot be securely fitted to
the power tool. If possible, transport unused saw blades
in an enclosed container.
– Turn the transport handle (3) so that it is vertical.
– Carry the power tool by the transport handle (3) or hold it
by the recessed handles (61) on the sides of the saw
table.
Only use the transport devices to transport the power
u
tool and never the protective devices or workpiece
supports.
