Dust/Chip Extraction; Starting Operation - Bosch PBS 75 A Manual Original

14 | English
This may significantly reduce vibration and noise emissions
over the total working period.
Implement additional safety measures to protect the oper-
ator from the effects of vibration, such as servicing the
power tool and application tools, keeping their hands warm,
and organising workflows correctly.
Assembly
Pull the plug out of the socket before carrying out any
u
work on the power tool.

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 reac-
tions 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 conjunction with wood treatment
additives (chromate, wood preservative). Materials contain-
ing asbestos may only be machined by specialists.
– Use a dust extraction system that is suitable for the ma-
terial 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. Dust can
u
easily ignite.
Self-generated dust extraction with dust box (see figures
A1–A4)
Place the dust box (6) on the extraction adapter (9) until it
engages. Attach the extraction adapter (9) to the extraction
outlet (10).
To empty the dust box (6), remove the dust box (6) with the
extraction adapter (9).
Before opening the dust box (6), knock the dust box against
a firm surface as shown in the figure to loosen the dust from
the filter element.
Take hold of the dust box (6) by the recessed grip, fold the
filter element (12) upwards out of the way and empty the
dust box. Use a soft brush to clean the flaps of the filter ele-
ment (12).
Note: The belt sander has a high material removal rate.
Therefore, to ensure optimum dust extraction, empty the
dust box (6) at regular intervals after every five minutes of
operation and clean the filter element (12) regularly.
External Dust Extraction
Fit a dust extraction hose onto the extraction outlet (10).
Connect the dust extraction hose to an extractor. You will
find an overview of connecting to various dust extractors at
the end of these operating instructions.
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.
Changing the Sanding Belt (see figures B–D)
– Swivel the clamping lever (3) all the way out. The sanding
belt (2) is now slack and can be removed.
– Fit the new sanding belt (2). Ensure that the arrow direc-
tions on the inner surface of the sanding belt and the
housing of the power tool match.
– Swivel the clamping lever (3) back to the starting posi-
tion.
– Lift up the power tool and switch it on. The belt running is
centred automatically when the tool is switched on and
during the sanding process.
If the belt running is not centred after switching the power
tool on, it may have to be manually adjusted. To do this, turn
the adjusting screw (13) on the front roller until the sanding
belt (2) runs at a distance of 2–3 mm from the aluminium
housing, see figure (D). Should the belt running still not be
centred after doing this, then the sanding belt (2) must be
replaced.
Selecting a Sanding Belt
Different sanding belts are available, depending on the ma-
terial you are working with and the required surface removal
rate:
For processing all wood and wood-based
materials
For pre-sanding, e.g. of rough and
uneven beams and boards
For surface sanding and levelling of
slight irregularities
For finishing and fine sanding of hard
woods
Operation

Starting Operation

Pay attention to the mains voltage. The voltage of the
u
power source must match the voltage specified on the
rating plate of the power tool. Power tools marked
with 230 V can also be operated with 220 V.
Products that are only sold in AUS and NZ: Use a resid-
u
ual current device (RCD) with a nominal residual current
of 30 mA or less.
Switching On and Off
Make sure that you are able to press the On/Off switch
u
without releasing the handle.
To switch on the power tool, press and hold the on/off
switch (5).
