Dust/Chip Extraction; Operating Modes - Bosch GKM 18V-50 Professional Originalbetriebsanleitung

– Attach the clamping flange (17) and screw in the clamp-
ing bolt (16) in rotational direction ➋. Ensure that the
mounting flange (19) and clamping flange (17) are in-
stalled in the correct position.
– Press and hold the spindle lock button (1).
– Use the hex key (5) to tighten the clamping bolt (16) in
rotational direction ➋. The tightening torque should be
6–9 Nm, which corresponds to hand-tight plus 1/8 turn.

Dust/Chip Extraction

The dust from materials such as lead paint, minerals and
metal can be harmful to human health. Touching or breath-
ing in this dust can trigger allergic reactions and/or cause
respiratory illnesses in the user or in people in the near vicin-
ity.
Certain kinds of metal dust are hazardous, especially in com-
bination with alloys such as zinc, aluminium or chrome. Ma-
terials containing asbestos may only be machined by special-
ists.
– Provide good ventilation at the workplace.
– It is advisable to wear a P2 filter class breathing mask.
The regulations on the material being machined that apply in
the country of use must be observed.
Avoid dust accumulation at the workplace. Dust can
u
easily ignite.
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 B)
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 (10). For a smaller cutting depth,
pull the saw away from the base plate (13); for a larger cut-
ting depth, push the saw towards the base plate (13). Adjust
the desired cutting depth at the cutting-depth scale.
Retighten the clamping lever (10).
The clamping force of the clamping lever (10) can be read-
justed. To do so, unscrew the clamping lever (10) and
retighten it in a position offset by at least 30° in an anticlock-
wise direction.
Note: If the ProCORE18V 12.0Ah battery is used, this may
sit on the workpiece during working. Consequently, the max-
imum cutting depth cannot be reached.
Bosch Power Tools
Cut marks
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.
Utility hook (see figure C)
Your power tool is equipped with a utility hook (3) for
hanging it to a ladder, for example. Simply fold out the utility
hook (3) to the required position.
When the power tool is hanging by the utility hook, en-
u
sure that the saw blade is protected against uninten-
ded contact in order to prevent injury.
Fold the utility hook (3) in again when you want to begin
work with the power tool.
Chip container (see figures F–G)
Caution: Do not touch the protective guard with chip
container (2) and the metal chips with bare hands immedi-
ately after operation. These parts can be very hot and cause
skin burns.
Do not cut material which has had thinner, petrol, grease or
other chemicals applied to it. The metal chips produced by
such materials could damage the protective guard with chip
container (2) and lead to a break that could cause personal
injury.
The metal chips are collected in the chip container of the
protective guard (2). Empty the chip container at regular in-
tervals.
To do this, push the chip container locking mechanism (25)
upwards. Open the lid of the chip container (24) and tilt the
power tool sideways to empty the chip container. After
emptying, close the lid of the chip container (24) and lock
the chip container again.
Start-up
Before carrying out any work with the power tool, en-
u
sure that the chip container is closed and locked.
Never operate the power tool without a protective
guard/with a defective protective guard/lid on the
chip container.
Inserting the battery
Push the charged battery (9) into the power tool until the
battery is securely locked.
