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.
Start-up

Switching on/off

Make sure that you are able to press the On/Off switch
u
without releasing the handle.
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. Applying too much pressure to the power tool
when moving it in the cutting direction significantly reduces
the service life of the application tools and can damage the
power tool.
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
GKS 18V-57-2 L
Choosing the right saw blade depends on the wood type,
wood quality and whether cuts with or against the grain are
required.
0
45
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.
Sawing with the parallel guide (see figure D)
The parallel guide (13) allows you to make precise cuts
along the edge of a workpiece and cut strips with the same
dimensions.
Sawing with an auxiliary guide (see figure E)
For working on large workpieces or for cutting straight
edges, you can securely fasten a board or rail to the work-
piece as an auxiliary guide. The circular saw can be guided
along the path of this auxiliary guide with the base plate.
Utility hook (see figure G)
Your power tool is equipped with a utility hook (30) for
hanging it to a ladder, for example. Simply fold out the utility
hook (30) to the required position.
u
Fold the utility hook (30) in again when you want to begin
work with the power tool.

Maintenance and Service

Maintenance and Cleaning

u
u
Remove the battery from the power tool before carry-
ing out work on the power tool (e.g. maintenance,
changing tool, etc.). The battery should also be re-
moved for transport and storage. There is risk of injury
from unintentionally pressing the on/off switch.
When the power tool is hanging by the utility hook, en-
sure that the saw blade is protected against uninten-
ded contact in order to prevent injury.
Remove the battery from the power tool before carry-
ing out work on the power tool (e.g. maintenance,
changing tool, etc.). The battery should also be re-
moved for transport and storage. There is risk of injury
from unintentionally pressing the on/off switch.
To ensure safe and efficient operation, always keep
the power tool and the ventilation slots clean.
