Bosch Professional GKS 18V-57 G Notice Originale page 21

No dust bags should be connected to the dust extrac-
u
tion adapter. Otherwise the extraction system can be-
come clogged.
To ensure optimum extraction, the dust extraction adapter
(28) must be cleaned regularly.
External dust extraction
Connect the extraction hose (35) to a dust extractor (ac-
cessory). You will find an overview of connecting to various
dust extractors at the end of these operating instructions.
The power tool can be directly connected to the socket of a
Bosch all-purpose dust extractor with remote starter. This
dust extractor is started up automatically when the power
tool is switched on.
The dust extractor must be suitable for the material being
worked.
When extracting dry dust that is especially detrimental to
health or carcinogenic, use a special dust extractor.
Operation
Remove the battery from the power tool before carry-
u
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.
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 (29). For a smaller cutting depth,
pull the saw away from the base plate (6); for a larger cutting
depth, push the saw towards the base plate (6). Adjust the
desired cutting depth at the cutting-depth scale. Retighten
the clamping lever (29).
The clamping force of the clamping lever (29) can be read-
justed. To do so, unscrew the clamping lever (29) and
retighten it in a position offset by at least 30° in an anticlock-
wise direction.
Setting the mitre/bevel angle (GKS 18V-57 G)
We recommend that you place the power tool down on the
front side of the protective guard (17).
Loosen the wing bolts (8) and (15). Swivel the saw to the
side. Set the required mitre angle on the scale (9). Retighten
the wing bolts (8) and (15).
Note: When making mitre cuts, the cutting depth is less than
the value shown on the cutting depth scale (30).
Setting the mitre/bevel angle (GKS 18V-57)
We recommend that you place the power tool down on the
front side of the protective guard (17).
Loosen the wing bolt (8). Swivel the saw to the side. Set the
required mitre angle on the scale (9). Retighten the wing
bolt (8).
Bosch Power Tools
Note: When making mitre cuts, the cutting depth is less than
the value shown on the cutting depth scale (30).
Cut marks (GKS 18V-57):
45 0
The 0° cut mark (11) indicates the position of the saw blade
when making a right-angled cut. The 45° cut mark (10) indic-
ates the position of the saw blade when making a 45° cut.
For a precise cut, place the circular saw against the work-
piece as shown in the figure. We recommend making a test
cut.
GKS 18V-57 G:
When using the FSN guide rail system, the power tool can
stay in the holder for the guide rail when making mitre cuts.
(10) Use only cut marks (10)
when making a right-angled
cut and a 45º cut with the
guide rail.
Start-up
Inserting the battery
Slide the charged battery (19) into the foot of the power tool
from the front. Press the battery fully into the foot until the
red stripe is no longer visible and the battery is securely
locked.
Switching on/off
To start the power tool, first press the lock-off switch (1),
then press and hold the on/off switch (18).
To switch off the power tool, release the on/off switch (18).
Note: For safety reasons, the on/off switch (18) cannot be
locked; it must remain pressed during the entire operation.
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.
