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.
Adjusting the Laser
– Bring the power tool into the working position.
– Turn the saw table 8 to the 0° detent 14. The lever 12 must
be felt to engage in the detent.
Checking: (see figure P1)
– Draw a straight cutting line on the workpiece.
– 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 slowly 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 P2)
– Undo the rubber cap 49.
– Screw the adjustment screw 50 in or out using a suitable
screwdriver until the laser beam is parallel with the cutting
line on the workpiece over the complete length.
Adjusting the Flush Levelling: (see figure P3)
– Turn the adjustment screw 51 with the Phillips screwdriv-
er provided until the parallel laser 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.
Adjusting the Lateral Deviation while Moving the Tool
Arm: (see figure P4)
– Loosen the three screws 52 of the laser protection cap 53
with the Phillips screwdriver provided.
– Move the retracting blade guard 6 completely to the rear
and lift off the laser protection cap.
– Screw the adjustment screw 54 in clockwise direction with
the Phillips screwdriver provided if the laser beam moves
toward the left when the tool arm is lowered.
Screw the adjustment screw 54 in anticlockwise direction
if the laser beam moves toward 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.
