– Set the required mitre angle as necessary.
– Switch the power tool on.
– Push the locking lever (1) and slowly guide the tool arm
downwards using the handle (16).
– Saw through the workpiece applying uniform feed.
– Switch off the power tool and wait until the saw blade has
come to a complete stop.
– Slowly guide the tool arm upwards.
Checking and adjusting the basic settings
Pull the plug out of the socket before carrying out any
u
work on the power tool.
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.
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. Accidental
starting of the power tool can lead to injuries.
– Bring the power tool into the work position.
Checking: (see figure K1)
– Draw a straight cutting line on the workpiece.
– Push the locking lever (1) and slowly guide the tool arm
downwards using the handle (16).
– 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 upwards.
– Clamp the workpiece.
– Turn on the laser beam using the switch (19).
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 K2)
– Turn the set screw (35) using the cross-headed screw-
driver (12) provided until the laser beam is parallel with
the cutting line on the workpiece along its entire length.
One rotation anticlockwise moves the laser beam from left to
right; one rotation clockwise moves the laser beam from
right to left.
Aligning the angle indicator (see figure L)
– Bring the power tool into the transport position.
– Loosen the clamping handle (13) of the angle guide (6).
– Turn the angle guide (6) until it stops at 0°.
Checking
– Set an angle gauge to 90° and position it between the
angle guide (6) and the saw blade (31) on the saw table
(25).
Bosch Power Tools
The leg of the angle gauge must be flush with the angle guide
along its entire length.
Setting
– Turn the angle guide (6) until the leg of the angle gauge is
flush with the saw blade along its entire length.
– Retighten the clamping handle (13).
– Undo the screw (36) with the cross-headed screwdriver
(12) provided and align the angle indicator along the 0°
mark.
– Retighten the screw.
Transport
Before transporting the power tool, the following steps must
be carried out:
– 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.
– Always carry the power tool by the transport handle (20).
Only use the transport devices to transport the power
u
tool and never the protective devices.

Maintenance and service

Maintenance and cleaning

Pull the plug out of the socket before carrying out any
u
work on the power tool.
Clean the air vents on your power tool regularly. The
u
motor's fan will draw the dust inside the housing and ex-
cessive accumulation of powdered metal may cause elec-
trical hazards.
In extreme conditions, always use a dust extractor if
u
possible. Blow out ventilation slots frequently and in-
stall a residual current device (RCD) upstream. When
machining metals, conductive dust can settle inside the
power tool, which can affect its protective insulation.
Have maintenance and repair work performed exclus-
u
ively by a qualified specialist. This will ensure that the
safety of the power tool is maintained.
In order to avoid safety hazards, if the power supply cord
needs to be replaced, this must be done by Bosch or by an
after-sales service centre that is authorised to repair Bosch
power tools.
The retracting blade guard must always be able to move
freely and retract automatically. It is therefore important to
keep the area around the retracting blade guard clean at all
times. Remove dust and chips with a paintbrush.
