Dust/Chip Extraction; Starting Operation - Berner BACOT 12V STARLOCK Manual Original

Position the required application tool (e.g. plunge
cut saw blade (10)) on the tool holder (7) so that
the depressed centre is facing downwards (see
figure on the graphics page, text on the applica-
tion tool should be legible from above).
Turn the application tool to a position which is
convenient for the job at hand and allow it to lock
into place in the cams of the tool holder (7).
Twelve positions offset by 30° are possible for
this.
Secure the application tool using the bolt (11).
Tighten the bolt using the hex key (12) until the
rounded head of the bolt is lying flat against the
application tool.
Check that the application tool is seated se-
u
curely. Application tools that are attached in-
correctly or are not securely fixed in place may
come loose during operation, thereby putting
you at risk.
Attaching/changing the sanding sheet on the
sanding plate
English
The sanding plate (15) is fitted with a hook-and-
loop fastening, allowing sanding sheets with a
hook-and-loop backing to be secured quickly and
easily.
Tap the hook-and-loop fastening of the sanding
plate (15) before fitting the sanding sheet (16) to
facilitate maximum adhesion.
Position the sanding sheet (16) so that it is flush
with one side of the sanding plate (15), then place
the sanding sheet on the sanding plate and press
it on firmly.
To ensure optimum dust extraction, make sure
that the punched holes in the sanding sheet are
aligned with the drilled holes in the sanding plate.
To remove the sanding sheet (16), take hold of it
by an edge and pull it away from the sanding
plate (15).
You can use all sanding sheets, polishing and
cleaning fleeces from the Delta 93 mm series in
the Berner range of accessories.
Sanding accessories such as fleece/polishing felt
are attached to the sanding plate in the same
way.

Dust/chip extraction

The dust from materials such as lead paint, some
types of wood, minerals and metal can be harmful
to human health. Touching or breathing in this
dust can trigger allergic reactions and/or cause
respiratory illnesses in the user or in people in the
near vicinity.
Certain dusts, such as oak or beech dust, are
classified as carcinogenic, especially in conjunc-
tion with wood treatment additives (chromate,
wood preservative). Materials containing asbestos
may only be machined by specialists.

Connecting the dust extraction system
(see figure A)
English
The dust extraction system (14) is only designed
for use with the sanding plate (15); it serves no
purpose when used together with other applica-

Always connect a dust extraction system for sand-
ing.
Remove the application tool for fitting the dust ex-
traction system (14) (accessory).
Slide the dust extraction system (14) as far as it
will go over the tool holder (7) onto the collar of
the power tool. Turn the dust extraction system to
the required position (not directly under the power
tool). Push the clamping lever (17) shut to fix the
dust extraction system in position.
Attach the dust extraction adapter (19) of the dust
extraction hose (20) to the dust extraction outlet
(18). Connect the dust extraction hose (20) to a
dust extractor (accessory).
The dust extractor must be suitable for the mater-
ial being worked.
When extracting dry dust that is especially detri-
mental to health or carcinogenic, use a special
dust extractor.
