Dust/Chip Extraction; Auxiliary Handle; Starting Operation - BTI EX 150 Manual Original

Note: Pads with diameters of 150 mm and 125
mm have different carriers. The pads can only be
fitted to the right power tool.
Note: When attaching the sanding pad, make
sure that the teeth of the catch mate with the re-
cesses in the sanding pad.
Note: Damaged sanding pads must only be re-
placed by an after-sales service centre authorised
to work with BTI power tools.

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.
– Use a dust extraction system that is suitable for
the material wherever possible.
– 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.
u
Dust can easily ignite.
Self-generated dust extraction with dust box
(see figures C–G)
English
Slide the dust box (7) onto the extraction outlet
(12). Turn the dust box in such a manner that its
recesses face against the tips on the extraction
outlet and the dust box can be felt to engage.
You can easily check the filling level of the dust
box (7) through the transparent container.
To empty the dust box (7), rotate slightly and pull
it back.
Unscrew the filter element (6) and pull it out of the
dust box (7). Empty the dust box.
Gently tap the filter element (6) against a solid
surface to loosen the dust. Use a soft brush to
clean the flaps of the filter element (6).
Note: In order to ensure optimum dust extraction,
empty the dust box (7) in good time and clean the
filter element (6) regularly.
When working on vertical surfaces, hold the
power tool with the dust box (7) facing down-
wards.
External dust extraction (see figure H)
Fit a dust extraction hose (13) onto the extraction
outlet (12). Mount the vacuum hose onto the ex-
traction outlet (as shown in the figure) in such a

manner that the lateral openings on the extraction
outlet remain free. This prevents the power tool
from adhering to the workpiece during sanding
and the surface quality of the workpiece from be-
ing impaired.
Connect the dust extraction hose (13) to an ex-
tractor (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.
When working on vertical surfaces, hold the power
tool with the dust extraction hose facing
downwards.

Auxiliary Handle

English
The auxiliary handle (1) enables comfortable
handling and optimum power distribution, with a
high sanding removal rate in particular.
Use the screw (2) to secure the auxiliary handle
(1) on the housing.
Operation
English

Starting Operation

English

u
voltage of the power source must match the

Preselecting the orbital stroke
teh English
You can even preselect the orbital stroke rate dur-
ing operation using the necessary orbital stroke
rate preselection thumbwheel (3).
1–2 Low orbital stroke rate
3–4 Medium orbital stroke rate
5–6 High orbital stroke rate
