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.

Adjusting the Laser

– Bring the power tool into the working posi-
tion.
– Turn the saw table 8 to the 0° detent 14. The
lever 12 must be felt to engage in the detent.
Checking: (see figure Q1)
– Draw a straight cutting line on the work-
piece.
– Push the locking lever 35 and guide the tool
arm slowly downward with the tool handle 5.
– Align the workpiece in such a manner that
the teeth of the saw blade are in alignment
with the cutting line.
– Hold the workpiece in this position and slow-
ly guide the tool arm upward again.
– Clamp the workpiece.
– Switch the laser beam on with switch 29.
The laser beam must be in alignment with the
cutting line on the workpiece over the complete
length, also when the tool arm is lowered.
Adjusting the Parallelism: (see figure Q2)
– Undo the rubber cap 49.
– Screw the adjustment screw 50 in or out us-
ing a suitable screwdriver until the laser
beam is parallel with the cutting line on the
workpiece over the complete length.
Adjusting the Flush Leveling: (see figure Q3)
– Turn the adjustment screw 51 with the Phil-
lips screwdriver provided until the parallel la-
ser beam is flush with the cutting line on the
workpiece over the complete length.
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.
Bosch Power Tools
Adjusting the Lateral Deviation while Moving
the Tool Arm: (see figure Q4)
– Loosen the three screws 52 of the laser pro-
tection cap 53 with the Phillips screwdriver
provided.
– Move the retracting blade guard 6 complete-
ly to the rear and lift off the laser protection
cap.
– Screw the adjustment screw 54 in clockwise
direction with the Phillips screwdriver pro-
vided if the laser beam moves toward the
left when the tool arm is lowered.
Screw the adjustment screw 54 in anticlock-
wise direction if the laser beam moves to-
ward the right.
– After adjusting, check the flushness with the
cutting line again. If required, align the laser
beam with the adjustment screw 51 again.
– Reattach the laser protection cap 53 again.
Aligning the Angle Indicator (Horizontally)
– Bring the power tool into the working posi-
tion.
– Turn the saw table 8 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 9.
Adjusting:
– Loosen the screw 55 with the Phillips screw-
driver provided and align the angle indicator
along the 0° mark.
– Retighten the screw again.
