Mounting the utility hook (see figures F–G)
Using a screwdriver, lever out the cover (3) from the recess
on the side. Mount the utility hook (30) and secure it with
two screws. Tighten the screws with a torque of 1.8–2 Nm.
The utility hook (30) can be swivelled.
Operation
Before carrying out any work on the power tool (e.g.
u
maintenance, tool change etc.), remove the battery
from the power tool. There is risk of injury from uninten-
tionally pressing the on/off switch.
Operating modes
Setting the cutting depth (see figure C)
Adapt the cutting depth to the thickness of the work-
u
piece. A space of less than the height of one full tooth
should be visible under the workpiece.
Loosen the clamping lever (7). For a smaller cutting depth,
pull the saw away from the base plate (15); for a larger cut-
ting depth, push the saw towards the base plate (15). Adjust
the desired cutting depth at the cutting-depth scale.
Retighten the clamping lever (7).
The clamping force of the clamping lever (7) can be readjus-
ted. To do so, unscrew the clamping lever (7) and retighten
it in a position offset by at least 30° in an anticlockwise direc-
tion.
Adjusting the mitre/bevel angle
We recommend that you place the power tool down on the
front side of the protective guard (17).
Loosen the clamping lever for mitre/bevel angle
preselection (9). Swivel the saw to the side. Set the required
mitre/bevel angle on the scale (8). Retighten the clamping
lever (9).
Note: When making mitre cuts, the cutting depth is less than
the value shown on the cutting depth scale (20).
Cut marks
GKS 18V-57-2
45 0
The cut mark (12) indicates the position of the saw blade
when making a right-angled cut.
For a precise cut, place the circular saw against the work-
piece as shown in the figure. We recommend making a test
cut.
Bosch Power Tools
Start-up
Switching on/off
u
To start the power tool, first press the lock-off switch (2),
then press and hold the on/off switch (1).
To switch off the power tool, release the on/off switch (1).
Note: For safety reasons, the on/off switch (1) cannot be
locked; it must remain pressed during the entire operation.
Switching on the LED worklight
The lamp (10) lights up when the on/off switch (1) is lightly
or fully pressed, meaning that the work area is illuminated in
poor lighting conditions.
Run-out brake
An integrated run-out brake shortens the time the saw blade
keeps running for after the power tool has been switched
off.
Protection Against Deep Discharging
The lithium-ion battery is protected against deep discharge
by the Electronic Cell Protection (ECP). When the battery is
discharged, the power tool is switched off by means of a pro-
tective circuit: The application tool no longer rotates.
Practical advice
u
The width of cut varies depending on the saw blade used.
Protect saw blades against shock and impact.
Guide the power tool evenly, pushing it gently in the cutting
direction in order to achieve a high cut quality. Applying too
much pressure will significantly reduce the service life of ap-
plication tools and can damage the power tool.
Always work with uniform feed and ensure that the speed of
the saw blade stays constant. Avoid increasing pressure
(e.g. when working with damp wood, pressure-treated con-
GKS 18V-57-2 L
struction timber or waste wood) and the resulting speed re-
duction in order to prevent the saw blade teeth from over-
heating.

The sawing performance and the quality of the cut essen-
tially depend on the condition and the tooth shape of the
saw blade. This is why you should only use sharp saw blades
that are suitable for the material being machined.
Sawing wood
Choosing the right saw blade depends on the wood type,
wood quality and whether cuts with or against the grain are
required.
Making cuts in spruce with the grain produces long, spiral-
shaped chips.
Beech and oak dust is especially detrimental to health.
Therefore, work only with dust extraction.
Make sure that you are able to press the On/Off switch
without releasing the handle.
Before carrying out any work on the power tool (e.g.
maintenance, tool change etc.), remove the battery
from the power tool. There is risk of injury from uninten-
tionally pressing the on/off switch.
