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
Note: To test the laser function, the machine must be con-
nected to power.
 While adjusting the laser (e. g. when moving the tool
arm), never actuate the On/Off switch. Accidental start-
ing of the power tool can lead to injuries.
– Bring the power tool into the working position.
Checking: (see figure K1)
– Draw a straight cutting line on the workpiece.
– Push the locking lever 1 and guide the tool arm slowly
downward with the tool handle 16.
– 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 19.
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: (see figure K2)
– Turn the adjustment screw 35 with the Phillips screwdriv-
er 12 provided until the laser beam is parallel to the com-
plete length of the cutting line on the workpiece.
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.
Aligning the Angle Display (see figure L)
– Bring the machine into the transport position.
– Loosen the tension handle 13 of the angle stop 6.
– Turn the angle stop 6 until the stop to the 0° position.
Checking:
– Adjust an angle gauge to 90° and position it between the
angle stop 6 and the saw blade 31 on the saw-table 25.
The leg of the angle gauge must be flush with the angle stop
over the complete length.
Adjusting:
– Twist the angle stop 6 until the leg of the angle gauge is
flush with the saw blade over the complete length.
– Retighten the tension handle 13.
– Loosen the screw 36 with the Phillips screwdriver 12 pro-
vided and align the angle indicator along the 0° mark.
– Retighten the screw again.
Bosch Power Tools
Transport
Before transporting the power tool, the following steps must
be carried out:
– Bring the machine into the transport position.
– Remove all accessories that cannot be mounted firmly to
the power tool.
If possible, place unused saw blades in an enclosed con-
tainer for transport.
– Always carry the power tool by its transport handle 20.
 The power tool should always be carried by two per-
sons in order to avoid back injuries.
 When transporting the power tool, use only the trans-
port devices and never use the protective devices.

Maintenance and Service

Maintenance and Cleaning

 Before any work on the machine itself, pull the mains
plug.
 Clean the ventilation slots of your power tool regularly
with a soft brush. The motor fan draws dust into the hous-
ing, and a large accumulation of metal dust can lead to
electrical hazards.
 In extreme conditions, always use dust extraction as
far as possible. Blow out ventilation slots frequently
and install a portable residual current device (PRCD).
When working metals, conductive dust can settle in the in-
terior of the power tool. The total insulation of the power
tool can be impaired.
 Have maintenance and repair work performed only by
qualified specialists. In this manner, it can be ensured
that the safety of the power tool is maintained.
The retracting blade guard must always be able to move freely
and retract automatically. Therefore, always keep the area
around the retracting blade guard clean.
If the replacement of the supply cord is necessary, this has to
be done by Bosch or an authorized Bosch service agent in or-
der to avoid a safety hazard.
